How to use this calculator

  1. Enter the bill. Many people tip on the amount before tax; use the total if you prefer.
  2. Enter the tip percentage.
  3. Enter how many people are splitting the bill.
  4. Turn on rounding to make each share a round amount; the tip shown then includes the extra.

The formula

Tip = bill × tip% ÷ 100 Total = bill + tip Per person = total ÷ people

Shares are shown to the smallest currency unit. Because amounts can't always split evenly, one person may need to pay a little more.

Worked example

$86.40 bill, 18% tip, 3 people

  1. Tip = 86.40 × 0.18 = $15.55 (15.552).
  2. Total = 86.40 + 15.552 = $101.95.
  3. Per person = 101.952 ÷ 3 = $33.98.
  4. With rounding up, each person pays $34 and the tip becomes $15.60 (about 18.06%).

These are the default values above.

Frequently asked questions

Should I tip on the amount before or after tax?

Either is common. Tipping on the pre-tax amount is a widespread convention; the difference is small.

How do I work out 20% quickly?

Move the decimal one place left to get 10%, then double it. On $45, 10% is $4.50, so 20% is $9.

Do tips count as income for the worker?

In the United States, yes. The IRS treats cash and non-cash tips as taxable income that employees must keep records of and report.

Can a tip replace part of a server's wage?

Under the U.S. federal FLSA, employers may count some tips toward minimum wage for tipped employees if conditions are met; many states have stricter rules.

What about a service charge already on the bill?

A mandatory service charge is generally not a tip. Check the receipt before adding a tip on top.
