Tip calculator

The tip is the bill multiplied by the tip percentage divided by 100, and the total is the bill plus the tip. On an $85 bill at 18% the tip is 85 × 0.18 = $15.30, so the total is $100.30. Divided between two people that is $50.15 each, including $7.65 of tip per person.

It rounds each person's share up to the next whole dollar and recalculates the total and tip from that. With an $85 bill at 18% split two ways, $50.15 becomes $51.00 each, the total becomes $102.00 and the tip rises from $15.30 to $17.00. Rounding never reduces the tip.

Etiquette guides in the US generally say tipping on the pre-tax amount is acceptable, but many people simply tip on the total shown on the check, which is a little more generous. Enter whichever figure you prefer as the bill; the calculator does not add tax itself.

In the United States 15% is the usual minimum for sit-down service, 18–20% for good service, and 10% or a few dollars for counter service or delivery. Many other countries tip far less or not at all, so check local custom when travelling. The default here is 18%.

No, the calculator divides the total equally. If one person ordered much more, run it once for the shared items and once for the extra, or use the percentage calculator to work out individual shares, then add the same tip percentage to each of them.
