Free General Calculator for Everyday Math
A simple, fast calculator for addition, subtraction, multiplication, division and percentages — right in your browser, no sign-up needed.
Keyboard works too — numbers, + − × ÷, Enter for =, Backspace to delete.
Everyday math, no extra steps
Enter a number
Tap the on-screen keys or type on your keyboard — both work exactly the same.
Pick an operation
Add, subtract, multiply, divide, or turn a number into a percentage in one tap.
See your result instantly
Press equals and the answer appears right away, with your working shown above it.
Sometimes you just need to do the math
Not every calculation needs a specialized tool. Splitting a bill, checking a discount, adding up a shopping list, or working out a quick percentage doesn't need a full spreadsheet or app download — it just needs a calculator that opens fast and gets out of the way.
This general calculator is built for exactly that: everyday arithmetic, done quickly, on any device, without creating an account or waiting for anything to load.
What it handles
- Addition, subtraction, multiplication and division
- Percentages, for quick discounts, tips or splits
- Chained calculations, so you can keep going without starting over
- Memory keys (M+, M-, MR, MC) to hold a number while you work

Common questions
Is this general calculator free to use?
Yes. The calculator is completely free, works directly in your browser, and doesn't need an account or any sign-up.
Does the calculator work on mobile?
Yes. The layout adjusts to fit phone and tablet screens, and every button is sized for tapping, not just clicking.
Can I use my keyboard instead of tapping buttons?
Yes. Number keys, the plus, minus, multiply and divide keys, Enter for equals, and Backspace all work the same as the on-screen buttons.
What do the memory buttons (M+, M-, MR, MC) do?
M+ adds the current result to memory, M- subtracts it from memory, MR recalls whatever is stored in memory back onto the screen, and MC clears the memory completely.
Is any of my calculation history saved or sent anywhere?
No. Every calculation happens locally in your browser. Nothing you type or calculate is stored or transmitted.
