How it works

See the formula, calculation method, and reasoning behind the result.

This tool calculates the tip amount by applying the selected tip percentage to the bill total.

The calculation works like this:

  • you enter the bill total
  • you enter the tip percentage
  • the calculator converts the percentage into a decimal
  • it multiplies that decimal by the bill total
  • it returns the tip amount

For example, an 18% tip on an $85.50 bill is $15.39.

This is helpful because percentage-based tip math is common but easy to miscalculate quickly when paying in person or on the go.
