How this calculator works
- Hourly: overtime hours are hours over 40. If you were paid nothing for them, the full 1.5× rate is owed. If you were paid straight time, the missing "half" is owed.
- Salaried (misclassified): courts differ. The high estimate treats your salary as pay for 40 hours, so overtime is owed at 1.5× (salary ÷ 40). The low estimate uses the "half-time" method, (salary ÷ total hours) × 0.5.
- Look-back: federal claims generally reach 2 years, or 3 if the violation was willful (details).
- Liquidated damages: the FLSA allows an additional amount equal to unpaid wages unless the employer proves good faith.
Daily overtime rules in states like California aren't included. If you work long days there, your number may be higher. See state laws.
