What Is PMI? Private Mortgage Insurance Guide

What PMI Is and Why It Exists

Private mortgage insurance, universally known as PMI, is a type of insurance that conventional mortgage lenders require when a borrower makes a down payment of less than 20% of the home's purchase price. Despite being paid by the borrower, PMI protects the lender against financial loss if the borrower defaults on the loan and the property sells at foreclosure for less than the remaining loan balance. This distinction is important: PMI provides zero direct financial protection to the homeowner. If you lose your home to foreclosure, PMI does not cover you in any way.

The reason PMI exists comes down to risk management and the economics of mortgage lending. When a borrower puts down 20% or more, the lender has a substantial equity cushion. Even if the housing market declines by 15%, the lender could still recover the full loan amount through foreclosure, because the borrower's equity absorbs the loss. However, when a borrower puts down only 5% or 10%, that cushion is thin. A modest market decline or depreciation due to property condition could leave the lender with a loss after foreclosure and sale. PMI transfers that risk from the lender to an insurance company, allowing lenders to make loans they would otherwise consider too risky.

The PMI industry in the United States is served by several private companies, including MGIC (Mortgage Guaranty Insurance Corporation), Radian, Essent, National MI, Enact (formerly Genworth), and Arch MI. These companies collect premiums from borrowers, pool the risk across millions of loans, and pay claims to lenders when borrowers default. The industry is regulated at both the state and federal level, with minimum capital and reserve requirements designed to ensure that PMI companies can pay claims even during severe economic downturns.

For the broader housing market, PMI plays a critically important role. Without it, most lenders would require all borrowers to make a minimum 20% down payment. On a $400,000 home, that means saving $80,000 before you can buy, which is a barrier that would prevent millions of Americans from achieving homeownership. PMI essentially allows lenders to extend credit to borrowers with smaller down payments while still managing their risk exposure. According to the Urban Institute, approximately 40% of home purchase mortgages have down payments below 20%, meaning PMI enables a very large share of all home purchases in the country.

It is worth noting that PMI applies only to conventional loans, which are mortgages not backed by a government agency. Government-backed loans have their own insurance mechanisms. FHA loans charge a Mortgage Insurance Premium (MIP), VA loans charge a funding fee (though no monthly mortgage insurance), and USDA loans charge both an upfront guarantee fee and an annual fee. Each of these programs has different rules, costs, and cancellation policies, which we will compare later in this guide.

How PMI Is Calculated

PMI premiums are not a flat rate applied uniformly to all borrowers. Instead, they are calculated based on a matrix of risk factors that determine how likely a given borrower is to default. The two most significant factors are the loan-to-value (LTV) ratio and the borrower's credit score. Additional factors include the loan amount, the type of property (primary residence, second home, or investment), the loan term, and whether the rate is fixed or adjustable.

The loan-to-value ratio measures how much of the home's value is financed by the mortgage. An LTV of 95% means the borrower put down 5% and borrowed the remaining 95%. An LTV of 90% means 10% down. An LTV of 85% means 15% down. As the LTV increases, so does the PMI rate, because higher LTV loans carry greater risk. A borrower at 95% LTV might pay a PMI rate of 0.90% to 1.50% per year, while a borrower at 85% LTV might pay only 0.30% to 0.70% per year.

Credit score is the other major determinant. PMI companies use FICO scores to assess default risk, and the rate differences can be substantial. For a borrower with 10% down (90% LTV), the annual PMI rate might be 0.35% for someone with a 760 credit score, 0.55% for a 720 score, 0.85% for a 680 score, and 1.30% or more for a 640 score. On a $300,000 loan, the difference between a 760 and 640 credit score translates to roughly $237 per month in additional PMI cost. This is one reason why improving your credit score before applying for a mortgage can yield significant monthly savings.

To illustrate the calculation process, consider a home purchased for $400,000 with a 10% down payment. The loan amount is $360,000, and the LTV is 90%. If the borrower has a 740 credit score, the PMI company might assign an annual rate of 0.45%. The annual PMI premium is $360,000 times 0.0045, which equals $1,620 per year. Divided by 12 months, the monthly PMI charge is $135. This amount is added to the principal, interest, taxes, and insurance to produce the total monthly mortgage payment.

PMI rates can also vary between PMI providers. Your lender may obtain quotes from multiple PMI companies and offer you the most competitive rate, or they may have a preferred provider. It is worth asking your lender which PMI company they are using and whether they have shopped around on your behalf. Some lenders have relationships with multiple providers and can offer rate comparisons, while others work exclusively with one company. You can use our PMI calculator to estimate your potential PMI cost based on your specific loan amount, down payment, and credit score.

Different Types of PMI (BPMI, LPMI, Split)

Not all PMI is structured the same way. There are four main types of private mortgage insurance, each with different payment structures, advantages, and drawbacks. Understanding these options allows you to choose the PMI arrangement that best fits your financial situation and long-term plans.

Borrower-Paid Monthly PMI (BPMI) is the most common type and what most people think of when they hear "PMI." With BPMI, the insurance premium is added as a separate monthly charge to your mortgage payment. You pay it every month until you reach the required equity threshold for cancellation (typically 80% LTV). The advantage of BPMI is that it is temporary and creates no impact on your interest rate. The disadvantage is that it increases your monthly payment for what could be seven to ten years or more, depending on how quickly you build equity. BPMI is straightforward to understand and easy to track, and the cancellation process is well-defined under federal law.

Lender-Paid Mortgage Insurance (LPMI) is an arrangement where the lender pays the PMI premium to the insurance company on your behalf, but compensates by charging you a higher interest rate on the loan. For example, instead of paying a separate PMI premium of $150 per month on top of a 6.5% interest rate, you might get a 6.875% interest rate with no separate PMI charge. The advantage is a lower total monthly payment in many cases, and you do not have to deal with PMI cancellation procedures. The significant disadvantage is that the higher interest rate lasts for the entire life of the loan, unless you refinance. With BPMI, the extra cost disappears once you reach 80% LTV, but with LPMI, you are permanently paying a higher rate. LPMI tends to be more cost-effective for borrowers who plan to sell or refinance within five to seven years.

Single-Premium PMI allows you to pay the entire PMI cost upfront at closing as a one-time lump sum. On a $300,000 loan with 10% down, the single premium might be $4,500 to $7,000, depending on your credit score and loan terms. The advantage is that you eliminate the monthly PMI charge entirely, which can help with debt-to-income ratio calculations and simplify your monthly budget. The disadvantage is the large upfront cost, which either comes from your cash reserves (reducing funds available for the down payment, moving expenses, or emergency reserves) or is financed into the loan amount (increasing your balance and interest costs). Single-premium PMI is typically best for borrowers with ample cash who want to minimize their monthly payment.

Split-Premium PMI is a hybrid approach where you pay part of the premium upfront at closing and the remainder as a monthly charge. This structure reduces the monthly PMI payment compared to full BPMI while requiring a smaller upfront payment than single-premium PMI. For example, you might pay $2,000 upfront and $75 per month instead of the full $150 monthly BPMI charge. Split-premium PMI can be a good option when you want to lower your monthly payment to meet DTI requirements for loan qualification but do not have enough cash for a full single premium.

Your lender should be able to present you with cost comparisons for the available PMI options. When evaluating them, consider your expected time in the home, your available cash at closing, your debt-to-income ratio situation, and whether you plan to refinance in the near future. There is no universally "best" type of PMI; the optimal choice depends entirely on your individual circumstances and financial strategy.

Monthly PMI Cost by Loan Amount

To help you budget for PMI, here are realistic monthly cost estimates across different loan amounts, down payment levels, and credit score tiers. These figures are based on typical PMI rate cards from major insurers and represent borrower-paid monthly PMI (BPMI) on 30-year fixed-rate mortgages for primary residences.

For a $250,000 loan (which might result from a $278,000 purchase with 10% down): a borrower with a 760+ credit score pays approximately $73 to $94 per month. With a 720 credit score, the range is $104 to $135 per month. At a 680 credit score, expect $156 to $208 per month. And at a 640 credit score, PMI can run $229 to $313 per month. These represent a meaningful range, with the low-credit-score borrower paying three to four times more than the high-credit-score borrower for the identical loan amount.

For a $350,000 loan (perhaps a $389,000 purchase with 10% down): the costs scale proportionally. At a 760+ credit score, monthly PMI is approximately $102 to $131. At 720, it is $146 to $189. At 680, the cost rises to $219 to $292. And at 640, expect $321 to $438 per month. For borrowers in this loan range, the PMI cost with a lower credit score can exceed the property tax portion of the monthly payment.

For a $500,000 loan (a $556,000 purchase with 10% down): PMI at a 760+ credit score runs approximately $146 to $188 per month. At 720, it is $208 to $271. At 680, the range is $313 to $417. And at 640, monthly PMI reaches $458 to $625. At this loan level, the difference in PMI cost between excellent and fair credit is approximately $400 per month, which is $4,800 per year and could total $35,000 or more over the life of the PMI before it is canceled.

The down payment percentage also has a major impact. Using a $400,000 loan as an example with a 720 credit score: at 5% down (95% LTV), the monthly PMI is approximately $280 to $333. At 10% down (90% LTV), it drops to $167 to $220. At 15% down (85% LTV), it falls further to $100 to $133. The jump from 5% down to 10% down can cut PMI costs nearly in half, which is an important consideration when deciding how much to put down. Use the down payment calculator to evaluate the trade-offs between a larger down payment and lower monthly PMI.

Keep in mind that these are estimates and actual rates vary by lender and PMI company. Your loan officer can provide a specific PMI quote during the pre-approval process, and the exact PMI amount will appear on your Loan Estimate (LE) and Closing Disclosure (CD) documents. If the quoted PMI seems high relative to industry averages, ask whether a different PMI provider might offer a better rate for your profile.

When Does PMI Automatically Cancel

The Homeowners Protection Act of 1998 (HPA), also known as the PMI Cancellation Act, established federal rules governing when PMI must be removed from conventional mortgage loans. This law provides important protections for borrowers and sets clear deadlines that lenders must follow. Understanding these rules ensures you do not pay PMI longer than legally required.

Under the HPA, there are two key thresholds. First, at the 80% LTV threshold, you have the right to request cancellation. When your loan balance reaches 80% of the original purchase price or appraised value at the time of purchase (whichever is lower), you can submit a written request to your loan servicer asking them to cancel PMI. For this request to be approved, you must be current on your payments, have a good payment history (no payments 30 or more days late in the past 12 months and no payments 60 or more days late in the past 24 months), and the lender may require you to certify that there are no junior liens on the property. Some lenders may also require a new appraisal or broker price opinion to confirm that the home has not lost value.

Second, at the 78% LTV threshold, your lender must automatically terminate PMI. This automatic cancellation is based on the original amortization schedule, meaning it occurs when your scheduled payments would have brought the balance to 78% of the original value, regardless of whether you have made extra payments. You must be current on your payments for automatic termination to occur. If you are not current, the lender must cancel PMI on the first day of the first month following the date you become current.

There is also a final termination date, which is the midpoint of the amortization period. For a 30-year mortgage, that is after 15 years of payments. At this point, PMI must be canceled even if the loan balance has not reached 78% of the original value. This provision protects borrowers with interest-only periods or other amortization structures where the balance may not decline as quickly.

A critical detail is that the HPA's automatic cancellation provisions are based on the original purchase price or original appraised value, not the current market value. This means that if your home has appreciated significantly, you are still technically bound by the original value for automatic cancellation purposes. However, you can use the home's current appraised value as part of a borrower-initiated cancellation request, which we will discuss in the next section. The law also requires lenders to provide annual written disclosures about your right to cancel PMI, including information about the dates when you may request cancellation and when automatic termination will occur.

How to Remove PMI Early

While waiting for automatic PMI cancellation can take seven to ten years or more through regular amortization, proactive borrowers have several strategies to eliminate PMI much sooner. Each approach requires meeting specific criteria, but the potential savings of hundreds of dollars per month make these strategies well worth pursuing.

The most straightforward method is to make extra principal payments to reach the 80% LTV threshold faster. If your original loan was $320,000 on a $400,000 home, the 80% threshold is $320,000, which is your starting balance, so you technically start at exactly 80%. But more commonly, if you put down 10% on a $400,000 home (borrowing $360,000), you need to reduce the balance to $320,000, which means paying down $40,000 in principal. Through normal amortization at 6.5%, this would take approximately 8.5 years. But by adding $300 per month to your payment, you could reach $320,000 in about 5.5 years, saving approximately 36 months of PMI payments. At $200 per month in PMI, that is $7,200 in savings.

Another powerful approach leverages home value appreciation. If your home's market value has increased substantially since purchase, your actual loan-to-value ratio may be well below 80% even if the original-value LTV has not reached that threshold. Most lenders allow you to request PMI cancellation based on the current appraised value, though they typically require a formal appraisal (which you pay for, usually $400 to $700). Some lenders require that you have owned the home for at least two years before allowing appreciation-based PMI removal, and many require that the current LTV be 75% or lower (rather than 80%) when using a new appraisal.

Home improvements that increase the property's appraised value can complement the appreciation strategy. Renovations such as kitchen remodeling (average return on investment of 60-80%), bathroom updates, adding livable square footage, or significant curb appeal improvements can boost your home's appraised value. However, not all improvements add dollar-for-dollar value, so be strategic. The goal is to spend less on improvements than the resulting PMI savings justify. If $15,000 in renovations pushes your appraisal high enough to eliminate $200/month in PMI, you recoup the investment in just over six years while enjoying the improved living space immediately.

Refinancing is another path to eliminating PMI. If your home has appreciated enough that a new loan would have an LTV of 80% or less, refinancing replaces your existing PMI-encumbered loan with a new loan that requires no PMI. The new loan is based on the current appraised value, not the original purchase price. However, refinancing involves closing costs (typically 2% to 3% of the new loan amount), so you need to ensure that the monthly PMI savings justify the refinancing expense. If your PMI costs $200 per month and refinancing costs $8,000 in closing costs, the breakeven period is 40 months. If you plan to stay in the home well beyond that, refinancing makes financial sense.

When you believe you qualify for PMI removal, contact your loan servicer in writing. Include your loan number, state that you are requesting PMI cancellation under the Homeowners Protection Act, and note that you are current on your payments. If you are requesting based on the original amortization schedule reaching 80%, provide your calculation. If you are requesting based on current appraised value, ask what documentation is required. Your servicer must respond within a reasonable timeframe, and if they deny the request, they must explain why in writing.

PMI vs FHA Mortgage Insurance (MIP)

One of the most common points of confusion among homebuyers is the difference between PMI on conventional loans and MIP (Mortgage Insurance Premium) on FHA loans. While both serve a similar purpose of protecting the lender against default, they differ significantly in structure, cost, and cancellation rules. Understanding these differences is essential when choosing between an FHA loan and a conventional loan.

FHA MIP has two components. The first is an Upfront Mortgage Insurance Premium (UFMIP) of 1.75% of the loan amount, paid at closing. On a $300,000 FHA loan, the upfront premium is $5,250. Most borrowers finance this amount into the loan rather than paying it out of pocket, bringing the total loan to $305,250. The second component is an annual MIP that is divided into monthly payments and added to your mortgage payment. For most borrowers (those with loans above $726,200 and LTV greater than 95%), the annual MIP rate is 0.55% of the outstanding loan balance. On a $300,000 loan, that is $1,650 per year, or $137.50 per month.

Conventional PMI, by contrast, has no mandatory upfront component (unless you choose single-premium or split-premium PMI). The monthly cost depends on your credit score, LTV, and other factors, as we discussed earlier. For a borrower with a 720 credit score and 5% down, conventional PMI might run 0.70% to 0.85% annually, which is higher than FHA's 0.55% annual rate. However, for a borrower with a 760+ credit score and 10% down, conventional PMI might be as low as 0.30% to 0.40%, significantly less than FHA MIP.

The most significant difference is cancellation policy. Conventional PMI can be canceled once you reach 80% LTV (borrower-requested) or is automatically terminated at 78% LTV. FHA MIP, for loans originated after June 3, 2013, with less than 10% down, cannot be canceled and lasts for the entire life of the loan. The only way to eliminate FHA MIP is to refinance into a conventional loan once you have sufficient equity. For FHA loans with 10% or more down, MIP can be removed after 11 years, but since most FHA borrowers put down only 3.5%, the lifetime MIP rule applies to the vast majority.

This cancellation difference has enormous long-term cost implications. Consider a borrower who takes a $300,000 loan and reaches 80% LTV after eight years. With conventional PMI at $175 per month, the total PMI cost over eight years is $16,800, after which it drops to zero. With FHA MIP at $137.50 per month (ignoring the declining balance for simplicity), the MIP continues for the remaining 22 years of a 30-year loan, adding approximately $36,300 more, for a total MIP cost of roughly $52,500 over 30 years. Add the $5,250 upfront premium, and the total FHA insurance cost is approximately $57,750 compared to $16,800 for conventional PMI. This is why borrowers with credit scores above 700 and the ability to put down 5% or more often find conventional loans with PMI more cost-effective than FHA loans in the long run.

Is PMI Tax Deductible in 2026

The tax deductibility of mortgage insurance premiums has a complicated legislative history in the United States. The deduction was first introduced as part of the Tax Relief and Health Care Act of 2006, which allowed homeowners to deduct PMI premiums as mortgage interest on their federal income tax returns. However, this provision was not made permanent and has required periodic renewal by Congress.

Over the years, the PMI deduction was extended, allowed to lapse, and then retroactively reinstated multiple times. The Consolidated Appropriations Act of 2020 extended the deduction through the end of the 2020 tax year. The Further Consolidated Appropriations Act of 2021 extended it through 2021. However, as of the writing of this article in early 2026, Congress has not enacted legislation extending the PMI deduction beyond its most recent expiration. This means that for the current tax year, mortgage insurance premiums are likely not deductible on your federal return.

When the deduction was available, it applied to mortgage insurance premiums on loans originated after January 1, 2007, for qualified residences. The deduction phased out for taxpayers with adjusted gross income above $100,000, decreasing by 10% for each $1,000 of income above that threshold, and fully phasing out at $109,000. Importantly, the deduction was only available to taxpayers who itemized deductions on Schedule A of their tax return, not to those who claimed the standard deduction. Given that the standard deduction for married couples filing jointly is $30,000 or more, many homeowners with PMI do not itemize and would not have benefited from the deduction even when it was active.

At the state level, tax treatment of PMI varies. Some states conform to the federal tax code and would allow the deduction if the federal provision is reinstated. Others have their own rules that may or may not include PMI deductibility. If you are in a high-tax state where itemizing is more common, the state-level treatment could be relevant.

The bottom line for 2026 tax planning is that you should not count on PMI being tax deductible when calculating the after-tax cost of your mortgage. If Congress reinstates the deduction (which it has done multiple times in the past), that would be a bonus. Consult a qualified tax professional or check the IRS website for the most current information about mortgage insurance premium deductibility for your specific tax year. When evaluating whether to put down less than 20% and pay PMI, base your analysis on the full pretax PMI cost rather than assuming a tax benefit that may or may not be available.

Alternatives to Paying PMI

If you want to avoid PMI altogether, several strategies are available, each with its own trade-offs. The right approach depends on your financial situation, how much cash you have available, and your risk tolerance.

The most obvious alternative is to save for a 20% down payment. On a $400,000 home, that means accumulating $80,000 plus additional funds for closing costs and reserves. For many buyers, particularly in high-cost markets, saving this amount takes years of disciplined saving. However, the math can be straightforward: if PMI costs you $200 per month, that is $2,400 per year. If it takes three additional years to save the extra down payment money, you would avoid $7,200 in PMI but miss three years of potential home price appreciation. In a market where home prices are rising 4% per year, a $400,000 home becomes a $449,000 home in three years, potentially costing you far more than the PMI you would have paid.

A piggyback loan (also called an 80-10-10 or 80-15-5) uses two mortgages to avoid PMI. The primary mortgage covers 80% of the home's value, a second mortgage (typically a home equity loan or HELOC) covers 10% or 15%, and the borrower puts down the remaining 5% or 10%. Since the primary mortgage is at 80% LTV, no PMI is required. The trade-off is that the second mortgage carries a higher interest rate than the first, typically 1% to 3% higher. You also have two separate loan payments to manage. Piggyback loans were very popular before the 2008 financial crisis and have made a moderate comeback, though they are not offered by all lenders.

VA loans are an excellent PMI alternative for eligible veterans, active-duty service members, and qualifying surviving spouses. VA loans require no down payment and no monthly mortgage insurance, regardless of LTV. They do charge a funding fee (typically 2.15% for first-time users with zero down), but this one-time cost is far less than years of PMI payments. Disabled veterans and Purple Heart recipients are exempt from the funding fee entirely. If you are eligible, a VA loan is almost always the most financially advantageous option. Learn more on our VA loan page.

Credit union and community bank programs sometimes offer conventional mortgages with no PMI requirement, even with less than 20% down. These programs may be limited to first-time buyers, certain income levels, or specific geographic areas. The trade-offs might include slightly higher interest rates, lower maximum loan amounts, or requirements to maintain a checking or savings account with the institution. These programs are worth investigating, particularly if you bank with a credit union that offers mortgage lending.

Finally, USDA loans are available for homes in eligible rural and suburban areas and require no down payment. Like FHA loans, USDA loans charge a guarantee fee (1.0% upfront and 0.35% annually), but these costs are lower than typical PMI or FHA MIP. If you are buying in an eligible area, a USDA loan can be a very cost-effective way to avoid traditional PMI. You can check USDA eligibility by property address on the USDA's website.

Is PMI Worth It or Should You Wait

The question of whether to accept PMI and buy now versus waiting to save a 20% down payment is one of the most important financial decisions prospective homebuyers face. The answer depends on several factors, including local housing market conditions, your savings rate, current mortgage interest rates, and your personal financial circumstances. Let us walk through the analysis.

Consider two scenarios for a $400,000 home. Buyer A puts down 10% ($40,000), borrows $360,000, and pays PMI of approximately $200 per month. Buyer B decides to wait three years to save an additional $40,000 for a full 20% down payment. If home prices appreciate at 4% per year, the same home costs $449,945 after three years. Buyer B now needs $90,000 for a 20% down payment (instead of $80,000) and borrows $359,956, which is essentially the same loan amount Buyer A had. But Buyer B missed out on three years of home equity building and paid rent during those three years.

Let us add up the numbers. Buyer A's total PMI cost over the roughly eight years until cancellation is approximately $19,200 ($200/month for 96 months). During those eight years, Buyer A built approximately $60,000 in equity through mortgage payments and, assuming continued 4% annual appreciation, gained approximately $175,000 in appreciation on the $400,000 home. Buyer B saved $19,200 by avoiding PMI but lost $49,945 in home price appreciation during the three-year waiting period and missed three years of equity building through mortgage payments (approximately $12,000). The net financial advantage of buying with PMI in this scenario is substantial.

However, there are scenarios where waiting makes more sense. If home prices are flat or declining in your market, the urgency to buy disappears and saving for a larger down payment reduces risk. If interest rates are expected to decline, waiting might result in a lower rate that more than offsets appreciation. If your current rent is very low relative to the cost of owning (less than 50% of the projected mortgage payment), the carrying cost of waiting is minimal. And if your credit score is below 680, the PMI cost will be high enough that improving your credit first could save you more than PMI alone.

For most buyers in markets with steady or rising home prices, PMI is a worthwhile cost that enables earlier entry into homeownership. Think of PMI as a temporary tool that lets you start building equity and benefiting from appreciation years sooner than you otherwise could. The key is to have a plan for eliminating PMI as quickly as possible, whether through extra payments, appreciation-based removal, or eventual refinancing. With that proactive approach, PMI becomes a short-term expense rather than a long-term burden. Use our affordability calculator to determine how PMI fits into your overall housing budget and whether your income comfortably supports the total payment including PMI.
