About Tip & Bill Splitter Calculator
Enter the total, tip percentage, and number of people to get each share.
How tip math works
Multiply the bill by the tip percentage to get the tip amount, add it to the bill for the grand total, then divide by the number of people. A 20 percent tip on an 80 bill is 16, making 96 total, or 24 each for four people. Whether tax goes in before the tip is a local custom: US diners usually tip on the pre-tax subtotal, while some regions tip on the total.
Splitting fairly when shares differ
Equal splits work when everyone ordered similarly. When one person ordered far more, split the shared items evenly and assign individual items to each diner, then apply the tip percentage to each share. Rounding each share to the nearest whole note usually leaves a small shortfall, so the organizer covers the remainder or rounds up.

Frequently Asked Questions about Tip & Bill Splitter Calculator
What is a standard restaurant tip?
In the US, 18 to 20 percent is standard for table service, 15 percent for casual spots, and 10 percent or less signals poor service. Many other countries include service in the bill, so check before adding more.
Do you tip on tax?
US convention is to tip on the pre-tax subtotal, which this calculator follows. Tipping on the after-tax total adds roughly 8 percent more tip, so pick one method and stay consistent.
How do you split a bill with different orders?
Assign each personal item to its diner, split shared items evenly, then apply the tip rate to each share. This keeps heavy and light orderers fair without mental arithmetic.
How should rounding be handled?
Round each share up to the nearest whole currency unit and let the small surplus cover the card fee or go to the tip. Rounding down leaves the bill short.
