How do I calculate a tip?
A tip is just a percentage of the bill, so you multiply the check by the rate written as a decimal. Eighteen percent is the bill times 0.18, which on a 50 dollar check is a 9 dollar tip and a 59 dollar total. Splitting is one more step: add the tip to the bill and divide by the number of people, so that 59 dollars across two diners is 29.50 each. This tip calculator chains those steps and updates as you type, and the round-up option tidies the total to a whole dollar when you'd rather not deal with change. It's quicker than doing it in your head, and you won't second-guess the split when the check is shared.

Frequently asked questions
Multiply the bill by the tip percentage as a decimal, so 18 percent is the bill times 0.18. On a 50 dollar check that's a 9 dollar tip and a 59 dollar total. This tip calculator does it the moment you type, and it'll split the total across your group too, so you don't have to do any mental math at the table.
For sit-down restaurant service, 18 to 20 percent of the pre-tax bill is the common range, with 20 percent the easy default for good service. Counter service, takeout, and coffee usually run 10 to 15 percent or a flat amount. The preset buttons above cover the usual choices, and you can type any percentage for the rest.
Custom is to tip on the pre-tax amount, since the tax isn't part of the service. In practice the difference is small, a few cents on most checks, so many people just tip on the total to keep it simple. Enter whichever figure you prefer as the bill, and the calculator works from that number.
Add the tip to the bill, then divide by the number of people. The tool does this for you: set the party size and you'll see the total per person and the tip per person. It splits evenly, which is the usual approach, and rounding up the total first keeps each share to a clean amount.
Turn on round up and the tool raises the total to the next whole dollar, then back-figures the tip to match, which makes the final number tidy. It's handy for cash, where you want a round total, or for splitting evenly without odd cents. The tip nudges up slightly, never down, so service is never shortchanged.
Yes to both. There's no sign-up, no limit, and nothing to install, since it runs in your browser. The amounts you enter stay on your device and aren't sent anywhere. Bookmark it on your phone and you'll have a fast tip-and-split tool ready the next time the check lands.
