How to Calculate the Tip

Cash tip left for a restaurant bill

Calculating the amount to tip can be done in a few easy steps. Start by dividing the tip percentage by 100 to get the percentage as a decimal.

tip as decimal = tip percentage ÷ 100

For example, if the tip percentage is 15%, divide 15 by 100 to find the decimal form, which is 0.15.

Next, multiply the tip percentage in decimal form by the total bill to calculate the amount to tip.

tip amount = bill amount × tip percentage

Thus, the tip amount is equal to the total bill amount times the tip percentage in decimal form.

For example, let’s calculate a 20% tip for a $75 bill.

tip as decimal = 20% ÷ 100
tip as decimal = 0.20

tip amount = $75 × 0.20
tip amount = $15

Thus, $15 would be a 20% tip on a $75 bill.

A Simple Trick to Calculate the Tip

Caught without your smartphone or a calculator? Here’s an easy way to calculate a tip without any tech.

Take the total bill and double it in your head, then shift the decimal point to the left one place. This will be a 20% tip amount.

For example, on a $100 bill, double the bill in your head – the result is $200. Then move the decimal point one place to the left, which is $20.0. Thus, the tip amount in this example is $20.
