Tip and Bill Split Calculator

Add a percentage tip and split the bill equally. See the tip, total and a last-person rounding adjustment so all payments add up exactly.

Round the bill and tip to cents. Tip = bill × tip rate; total = bill + tip. Divide total cents by people and round down for all but the last person. The last person pays the remaining cents so the sum is exact.

Example: a THB 1,000 bill with a 10% tip totals THB 1,100. Four people pay THB 275 each. For three people, the first two pay THB 366.66 and the last pays THB 366.68.

The tip is your choice, not a mandatory rate. Enter a bill that already includes taxes and service charges; these are not added again. This does not split individual menu items.
