About

Our mission is to make gross-pay estimates easier to understand and check. Overtime Pay Calculator gives workers and small employers free tools for overtime, time-and-a-half, double-time, holiday and shift-pay scenarios. Every result shows the rate, hours and multiplier it used so you can review the calculation line by line.

Every result shows its working, and every figure the calculators use is listed onhow we calculate with the source it came from.

Everything runs in your browser. There is no account, nothing is stored, and nothing you type is sent anywhere.

Corrections

If a figure looks off, the fastest fix is a specific one: which calculator, what you entered, what you expected, and the source you are comparing against. Any correction is reflected on the how we calculate page.

We show the assumptions and official source links so you can see what a calculation includes and excludes. Use the contact page or email contact@overtimepaycalculator.org with a reproducible example. About page reviewed October 8, 2026.

Limits

These are gross-pay estimates for planning and for checking a paycheck. They do not decide whether a job is covered or exempt, they do not calculate taxes, and they are not legal advice. For a dispute about unpaid overtime, contact the US Department of Labor's Wage and Hour Division or your state labor agency.
