How to calculate a tip
Multiply the bill by the tip percentage. For an $85 bill with an 18% tip: 85 × 0.18 = $15.30, so the total is $100.30. To split it, divide the total by the number of people.
Quick mental math
- 10%: move the decimal point one place to the left.
- 15%: find 10%, then add half of that amount.
- 20%: find 10% and double it.
Typical tipping in the US
For table service in restaurants, many diners tip between 15% and 20% of the pre-tax bill, with higher amounts for exceptional service. Customs for bars, delivery, taxis and personal services vary, and tipping culture is different in other countries, so check local norms when you travel.
Splitting the bill fairly
The calculator divides the bill and tip evenly. If people ordered very different amounts, it may be fairer to split the bill by item and tip on each person's share. Use the rounding option to land on an easy total when paying by cash.
