How to Calculate a Tip — and What to Tip

Tipping is a voluntary payment added to a bill to reward good service. In the United States, tipping is a cultural norm at restaurants, bars, salons, and with delivery drivers. The standard tip at a sit-down restaurant is 15–20% of the pre-tax bill. For exceptional service, 25% or more is appropriate. When splitting a bill, it is courteous to calculate the tip on the full bill first, then divide the total equally.

Worked Example

A dinner bill is $87.50 for a table of 4. You want to tip 20%. Tip = $87.50 × 0.20 = $17.50. Total = $87.50 + $17.50 = $105.00. Per person = $105.00 ÷ 4 = $26.25. Quick mental math trick: find 10% ($8.75) and double it ($17.50) for a 20% tip.

How to calculate a tip — and how much to leave

Tipping customs vary by country and service type, but the math is always the same: Tip = Bill × (Tip % ÷ 100). To split the total evenly, add the tip to the bill and divide by the number of people: Per person = (Bill + Tip) ÷ People.

Worked example: A $85 dinner for 4 people with a 20% tip: Tip = $85 × 0.20 = $17. Total = $102. Per person = $102 ÷ 4 = $25.50.
