Mortgage Points Calculator — Buy Down Your Rate

What Are Mortgage Discount Points?

Mortgage discount points, commonly called "points," are upfront fees paid directly to the lender at closing in exchange for a reduced interest rate on your mortgage. Each point costs 1% of the loan amount and typically reduces the interest rate by approximately 0.25 percentage points, though the exact reduction varies by lender and market conditions. On a $320,000 loan, one point costs $3,200 and would reduce a 6.875% rate to approximately 6.625%. Points are essentially prepaid interest: you pay more upfront to save money over the life of the loan through lower monthly payments. The Consumer Financial Protection Bureau (CFPB) explains that points are tax-deductible in the year they are paid for a purchase mortgage, making them particularly attractive for buyers in higher tax brackets. Discount points should not be confused with origination points, which are lender fees for processing the loan and do not reduce the interest rate. When comparing loan offers, always distinguish between these two types of points.

How Points Reduce Your Rate

The relationship between points and rate reduction is not always exactly 0.25% per point but follows a generally consistent pattern. In the current rate environment, one point on a 30-year fixed mortgage typically buys a 0.25% reduction, while 15-year mortgages may offer slightly larger reductions per point because the lender's risk period is shorter. Some lenders offer fractional points: half a point (0.5%) of the loan amount might reduce the rate by 0.125%. The Freddie Mac Primary Mortgage Market Survey tracks average rates and points charged, showing that points fluctuate with market conditions. In a higher rate environment, lenders may offer more generous reductions per point to attract borrowers. On a $320,000 loan, reducing the rate from 6.875% to 6.625% with one point lowers the monthly payment from approximately $2,101 to $2,047, saving $54 per month. Over 30 years, that $54 monthly savings totals $19,440, minus the $3,200 upfront cost, yielding a net lifetime savings of $16,240. The key decision is whether the upfront cost justifies the long-term savings based on how long you plan to keep the loan.

Breakeven Analysis for Mortgage Points

The breakeven point is the most critical calculation when deciding whether to buy mortgage points. It represents the number of months you must keep the loan before the accumulated monthly savings equal the upfront cost of the points. Using the example of one point on a $320,000 loan that saves $54 per month and costs $3,200, the breakeven occurs at approximately 59 months, or just under five years. If you sell the home, refinance, or otherwise pay off the mortgage before reaching breakeven, you lose money on the points. If you keep the loan beyond breakeven, you profit from the lower rate for every remaining month. According to the National Association of Realtors, the median homeownership duration in the United States is approximately 13 years, well beyond typical breakeven periods of three to seven years. However, refinancing activity can shorten your actual loan duration. If rates drop significantly after you purchase, you might refinance before reaching breakeven, negating the benefit of the points. Consider your expected timeline carefully: if you plan to stay in the home for more than seven years and believe rates are unlikely to drop substantially, points are generally a sound investment.

When It Makes Sense to Buy Points

Buying mortgage points is most advantageous under specific financial circumstances. The strongest case exists when you plan to stay in the home for at least seven to ten years, have sufficient cash beyond the down payment and closing costs, and are in a higher tax bracket where the point deduction provides immediate tax benefit. Points are also attractive when you have extra funds that would otherwise sit in a low-yield savings account: the effective return from buying points often exceeds 8% to 12% annually after breakeven, far outpacing most savings vehicles. Conversely, points are a poor choice if you are stretching to make the down payment, expect to move within five years, anticipate refinancing if rates drop, or need the cash for emergency reserves. The Bankrate mortgage points analysis suggests that in a declining rate environment, avoiding points and retaining the flexibility to refinance is often the better strategy. Many lenders also offer "negative points" or lender credits, where you accept a slightly higher rate in exchange for cash toward closing costs, which is the opposite strategy and may suit buyers with limited upfront funds.

Points vs. a Larger Down Payment

When you have extra cash available at closing, you face a strategic choice between buying points and making a larger down payment. Both options reduce your monthly payment, but through different mechanisms. A larger down payment reduces the loan amount directly, which lowers the monthly payment and may eliminate PMI if you reach 20% down. Buying points keeps the loan amount the same but reduces the interest rate, lowering the interest portion of each payment. Consider a $400,000 home where you have an extra $4,000: putting that toward the down payment (increasing it from 20% to 21%) reduces the loan from $320,000 to $316,000 and saves approximately $26 per month. Using that same $4,000 to buy 1.25 points reduces the rate by 0.3125% and saves approximately $67 per month. In this scenario, points provide a larger monthly savings, but the down payment option also builds immediate equity. According to financial analysis from the CFPB, if you are below the 20% down payment threshold, putting extra cash toward the down payment to eliminate PMI almost always provides a better return than buying points. Once you have cleared 20% down, points become the more efficient use of additional cash.
