About
Maintained by the overtimecalculator.fyi team · Last updated April 20, 2026
overtimecalculator.fyi is a free, fast, private tool for figuring out what your overtime is actually worth.
It supports the most common rule sets — federal FLSA, California's daily overtime, custom tiered multipliers, and salary-to-hourly conversions — without burying you in forms or asking you to sign up.
Everything runs in your browser. There's no backend, no analytics, no account. Your inputs live in the URL so you can bookmark or share a calculation, but nothing leaves your device.

- · Shift workers planning the week ahead
- · Freelancers quoting overtime rates

This tool provides estimates only. Not legal, tax, or accounting advice.
