What helps
- For a wrong result, the mode you used and the exact numbers you entered.
- For a display problem, the device and browser you were on.
- For a feature idea, what you were trying to work out.
This site does percentage math. It doesn't give financial, tax, or legal advice. See the terms of use, and the privacy policy for how contact messages are handled.
Every correction sent here gets checked against the percent change formula before anything on the calculator changes, and the numbers from the report become a new test case for later updates.
