Free Overtime Pay Calculator

How it works

Enter your hourly rate, how many regular hours you work each week, and how many overtime hours you put in — then pick your overtime multiplier. This calculator breaks down your weekly pay and scales it up to monthly and annual estimates.

How the math works

Weekly pay has two parts: regular pay = hourly rate × regular hours, and overtime pay = hourly rate × multiplier × overtime hours. At time and a half (1.5×), a $20/hour worker earns $30 for each overtime hour. The monthly estimate spreads a year of weekly paychecks evenly — weekly × 52 ÷ 12 — and the annual estimate is simply weekly × 52.

Everyday uses

• Paycheck checks: verify a payslip that includes overtime matches what you actually worked.
• Shift decisions: see exactly what picking up an extra weekend shift adds per month before you commit.
• Job comparisons: compare a lower-rate job with guaranteed overtime against a higher-rate job without it.
• Budgeting busy seasons: estimate income during peak periods when overtime is heavy, and plan savings around it.

Frequently asked questions

Q: When does overtime legally kick in? A: Under US federal law (the FLSA), most hourly, non-exempt employees must be paid at least 1.5× their regular rate for hours worked beyond 40 in a single workweek. Some states add daily rules — California, for example, requires overtime after 8 hours in a day. Salaried exempt employees are generally not entitled to overtime.

Q: Why is the monthly figure not just weekly × 4? A: A month is longer than four weeks — there are 52 weeks in a year but only 48 in twelve 4-week blocks. Multiplying by 52 and dividing by 12 spreads the extra four weeks across the year, giving a monthly average you can budget against.

Q: Is this my take-home pay? A: No — these are gross figures before income tax, Social Security, Medicare, and any deductions. Overtime can also push part of your income into a higher withholding bracket on a given check, though it settles out when you file your annual return.
