What is it?
Under the US Fair Labor Standards Act (FLSA), non-exempt employees must be paid at least 1.5x their regular rate for all hours worked beyond 40 in a workweek. This calculator splits total hours into regular and overtime, applies the chosen multiplier, and shows total gross pay and an effective hourly rate. Some states (CA, CO) have daily overtime rules (OT after 8 hrs/day) that this calculator does not cover — it is a weekly calculator only.
How to use
Enter the employee total hours worked this week, their base hourly rate, and the overtime multiplier (1.5x is FLSA standard). Adjust the regular-hours threshold if your contract or state law differs from 40 hours. The calculator splits hours automatically and computes gross pay.
Example scenario
An employee works 45 hours at $25/hour with a 1.5x overtime rate. Regular pay: 40 x $25 = $1,000. Overtime pay: 5 x $25 x 1.5 = $187.50. Total: $1,187.50. Effective hourly rate = $1,187.50 / 45 = $26.39.
Pro tip
If your employees regularly work overtime, model the annual cost of hiring an additional part-time employee versus the overtime premium. Persistent overtime often signals understaffing and can lead to burnout — the marginal cost of a new hire may be less than sustained overtime premiums plus turnover costs.
