Why Use Our Overtime Calculator?
Calculating overtime pay by hand is error-prone — especially with different state rules. Our calculator handles the complexity for you.
All 50 States
Federal and state weekly rules for every US state; Daily mode on the main calculator for CA daily OT and double time.
Time and a Half & Double Time
Weekly 1.5× by default; Daily mode on this calculator applies 1.5× and 2× where your state requires daily thresholds.
Hourly & Salaried
Works for both hourly employees and salaried workers with salary-to-hourly conversion.
Instant Breakdown
See regular pay, overtime pay, and total earnings with a detailed hour-by-hour breakdown.
Verify Your Paycheck With Confidence
Payroll errors on overtime are more common than most people think. A 2019 report from the Economic Policy Institute estimated that workers lose billions of dollars annually due to wage theft — with overtime miscalculations being a leading cause. Our calculator lets you independently verify whether your paycheck reflects the correct overtime amount.
Simply enter your hourly rate and total hours worked, then select your state. The calculator applies the correct threshold — whether that is the federal 40-hour standard, or a state-specific rule like daily overtime — and shows an estimated total based on the rules this calculator models. If there is a discrepancy between our result and your paycheck, it may be worth reviewing with your HR department.
This tool works for both hourly employees and salaried workers. Want to understand the math behind the numbers? Read our step-by-step overtime guide or see the overtime formula breakdown.
Estimates only — not legal, tax, or financial advice. Overtime and PTO rules vary by state, employer policy, and individual circumstances. Results are for informational purposes. Consult a qualified professional or your state labor agency for definitive guidance. See our Terms of Service.

Overtime Calculator FAQ
