Limits and formats

This tool finds a percentage of a value, not the change between two values.
Numbers must follow the field order shown by the interface.
Rounded output is fine for quick checks but not for official accounting.
An imported text file should be simple so the numbers are read correctly.
The page does not replace a spreadsheet for long lists of calculations.

Where processing happens

Your numbers remain inside the browser while the percentage is calculated. The operation runs on your device, and no data is sent away from it. Nothing is stored after you close the page.

Frequently asked questions

How is this different from percentage change?

This page answers questions such as what is 15 percent of 200. Percentage change compares an old value with a new one. Use the other tool when you need to know whether something went up or down, and choose the one that matches your question.

Can I import a file for this calculation?

The input accepts simple text files, but typing two numbers is usually faster. If you import a file, check that the base value and the percentage are in the expected order. The processing still happens in your browser and nothing is sent away.

Will the result be rounded?

The displayed answer comes from the numbers you entered and may include decimals. Rounding depends on how you read or reuse it. For invoices or reports, compare it with the rounding rule you normally apply before using the figure.
