Multiply the bill by the tip percent and divide by 100 — a 15% tip on a 100 bill is 15, making the total 115; divide that total by the number of people to split it.
Results are computed from your inputs and rounded for display. Verify important figures independently.
Enter the bill, choose a tip percent, and — if you are sharing — how many people are paying. The calculator shows the tip amount, the total including tip, and the per-person share, all computed in your browser.
Formula & methodology
Tip = bill × percent ÷ 100
Total = bill + tip
Per person = total ÷ people
Results are rounded at the sixth decimal for display; currencies are up to you — the math is unit-free.
Worked examples
Bill 84.50 at 18% split by two → tip 15.21, total 99.71, each pays 49.855 (round to your smallest coin).
Bill 200 at 12.5% split by four → tip 25, total 225, each pays 56.25.
Limits
Tipping customs differ by country — some places include service, others expect nothing at all. The calculator applies exactly the percent you choose and nothing else; check the receipt for an already-included service charge first.
Frequently asked questions
Should I tip on the amount before or after tax?
Customs vary; many people tip on the pre-tax amount. Enter whichever base you prefer as the bill — the calculator applies your percent to exactly what you enter.
How do we split fairly when the division is not exact?
The per-person figure is shown unrounded to six decimals; round each share up to the smallest coin and the small surplus becomes part of the tip.
