Reporting a wrong result

If a calculator gives an answer you think is wrong, please include:

• the page address (for example, freetoolhq.com/time-card-calculator/)
• the values you entered and the settings you used
• the result you got, and the result you expected

Please don't send personal information such as Social Security numbers or bank details. We never need it.

Tell us which calculator or tool you wish existed. Suggestions help us decide what to build next.
