Tip Calculator

A 15% tip on a 80 bill is 12, for a total of 92 (23 each for 4).

How it works

• Multiplied the bill by the tip percentage and divided by 100.
• Added the tip to the bill for the total.
• Divided the total by the number of people for the per-person share.

tip = bill × tip% / 100 = 80 × 15 / 100 = 12

• Assumes the tip is a percentage of the pre-tax bill, as most tipping conventions do.
• This is an illustration for information only and is not financial advice.
