Open calculatorChoose the right everyday calculator
Use the percentage calculator to find a portion of a number, the discount calculator to subtract a percentage from an original price, and the tip calculator to add a service percentage and divide the total. Each tool shows the formula and intermediate values so you can check the result.
- Enter percentages as ordinary values such as 20 for 20%, not 0.20.
- Check whether a tip should be based on the pre-tax or after-tax amount for your situation.
- Treat displayed currency symbols as labels; the arithmetic works with any currency when all inputs use the same one.
