Calculator
Make everyday calculations with a simple calculator.
How to use this tool
Type an expression or use the keypad, then press Enter or equals. Parentheses run first, multiplication and division next, followed by addition and subtraction.
What to know about the result
For example, (24 + 8) / 2 gives 16. Use * for multiplication and / for division when typing. The % operator returns a remainder; it is not a percentage button. To calculate 15% of 80, enter 80 * 15 / 100. Results use JavaScript number arithmetic and are rounded to 12 significant digits.
Frequently asked question
Can I use this for exact financial calculations?
It is an everyday calculator, not an accounting system. Binary floating-point arithmetic can introduce small rounding differences; confirm financial results using the required rounding rules.
