About this tool
A tip calculator turns a bill and a percentage into the tip you should leave and what you pay overall. This page uses those two fields and a Calculate button, with tip equal to bill times percent divided by 100 and total equal to bill plus tip.
How to use
- Open the calculator: Open Tip Calculator in your browser.
- Enter the bill: Type the pre-tip amount into Bill.
- Set the tip percent: Enter Tip % such as 15 or 20.
- Calculate: Click Calculate and read Tip and Total in the result.
Common use cases
- Split a restaurant check by computing tip and total before you pay.
- Compare 15% versus 20% tip on the same bill without a phone calculator.
- Double-check a receipt tip line when the percent looks off.
Tips
- Use plain numbers for Bill and Tip %—letters or blanks trigger an invalid-number message.
- Tip and Total are rounded to two decimals after Calculate.
