What Overtime Calculator does, with a checked example

Enter an hourly rate, regular hours, overtime hours, and optional double-time hours, and this tool returns regular pay, overtime pay at 1.5x, double-time pay at 2x, and a weekly gross total, then scales the week into biweekly and monthly gross-pay summaries. The math is plain multiplication on what you type. The thing people most often get wrong: overtime is measured per workweek - every hour over 40 in the employer's fixed seven-day workweek - not per day and not per pay period, so an under-40 week never cancels out an over-40 one.

Worked example

A concrete input and expected output from the current implementation.

Input

Hourly rate $20, 40 regular hours, 5 overtime hours, 2 double-time hours

Expected output

Regular pay $800.00 (40 x $20); overtime pay $150.00 (5 x $30, since $20 x 1.5 = $30); double-time pay $80.00 (2 x $40); weekly gross $1,030.00; biweekly $2,060.00; monthly $4,463.33

Each hour bucket is paid at its own rate - regular at $20, overtime at $30, double time at $40 - and the $1,030 weekly total is scaled by x2 for biweekly and x52/12 for monthly, assuming the same week repeats.

How the result is produced

1

The 40-hour weekly threshold

Under the federal Fair Labor Standards Act, covered non-exempt employees earn at least 1.5x their regular rate for hours over 40 in the employer's fixed seven-day workweek. This tool charges the premium only to the overtime hours you enter above regular hours, so entering 45 total hours as 40 regular plus 5 overtime matches the federal rule, while entering 45 regular hours misses the premium entirely.

Rate math and period scaling

The overtime rate is hourly rate x 1.5 and the double-time rate is hourly rate x 2, applied to the hours in each bucket. Weekly gross is the sum of the three buckets. The biweekly figure is the weekly total times 2, and the monthly figure is weekly times 52/12 - an annualized average, not a calendar-month calculation. The tool holds no state or employer policy data, so the rates are exactly what you enter.

Good uses

  • Verifying a paycheck stub after a week that ran over 40 hours - re-enter your hours and rate to confirm the employer's regular, overtime, and double-time lines add up.
  • Estimating gross pay for a budget or loan application when your schedule includes premium-rate shifts, since lenders and budgets work from gross, not take-home.
  • Comparing shift offers - deciding whether the 2x double-time shift on a holiday pays meaningfully more than the 1.5x overtime shift before committing to it.

Limits and checks

  • The biweekly and monthly rows assume the identical week repeats. If your hours swing - 50 one week, 35 the next - the summaries miss the swing, and the 50-hour week's overtime is not offset by the short week, because overtime is counted per workweek, never averaged across weeks.
  • This is gross pay, not net. No income tax, Social Security, Medicare, or other deductions appear. It also makes no legal call: whether you are exempt from overtime is a classification question, and state daily-overtime rules (California requires 1.5x after 8 hours and 2x after 12) are not modeled.
  • A 2x double-time rate is not a federal floor - it comes from union contracts, company policy, or certain state laws. If your employer pays only 1.5x for those hours, entering them as double-time overstates the check. And if you earn bonuses or commissions, the premium's regular rate must include them, so flat rate x 1.5 can understate what is owed.

Common questions

I worked 45 hours one week and 35 the next. Do they average out to 40 so there is no overtime?

No. Overtime is computed per workweek, not per pay period, so the 5 hours over 40 in the first week earn the 1.5x premium and the short second week does not cancel them. Averaging hours across weeks is not allowed for most covered employees. The tool mirrors this: you enter each week's hours separately.

Does this tell me my take-home pay?

No. The result is gross pay - the full amount before deductions. To get net pay you would subtract federal and state income tax, Social Security and Medicare withholdings, and any benefits or garnishments, which depend on your location, filing status, and employer. Use this tool for gross comparisons, then apply your own tax estimate.
