How this instrument works
Overtime pay is the extra owed once a week's hours run past 40 — federal wage law sets that threshold and puts a floor of 1.5 times the regular rate on every hour beyond it. This instrument prices exactly one week: a straight-time band up to 40 hours and a premium band for whatever comes after, kept as two separate lines instead of one blended average, because that is how an actual pay stub lists them.
The Overtime multiplier is a field here rather than a number baked into the formula, and that choice is deliberate. 1.5x covers most hourly workers most of the time, but it is not the only rate paid in practice — some employers owe double pay for a holiday shift or a seventh consecutive workday under contract, and a few states run a separate daily-hours rule with its own rate alongside the usual weekly one. Typing 2 into the multiplier prices a double-time week using the same two formulas; typing whatever a contract or state schedule specifies prices that instead. One instrument, several pay structures, because only the multiplier changes.
A payroll clerk running a quick gross-pay check without opening full payroll software, an hourly employee cross-checking their own pay stub, and a manager pricing out a week before approving overtime hours all open this calculator for the same reason — a fast, itemized answer. It covers gross pay for one workweek only: no tax withholding, no shift differential, and no day-by-day breakdown for the states — California among them — that count overtime inside a single shift rather than across the whole week.
- Enter your straight-time wage in Hourly rate, $.
- Enter the straight-time hours worked, up to 40, in Regular hours (up to 40).
- Enter only the hours past that point in Overtime hours (beyond 40) — not the week's full total.
- Leave Overtime multiplier at 1.5 for the standard federal rate, or change it to price double time or a different contracted rate.
- Read Regular pay, $ and Overtime pay, $ separately, then check Total weekly pay, $ for the combined total.
Worked example — 40 regular hours, 10 hours of overtime
Put 20 into Hourly rate, $, 40 into Regular hours (up to 40), 10 into Overtime hours (beyond 40), and leave Overtime multiplier at its default of 1.5. Regular pay, $ works out to 20 times 40, or $800.00 — untouched by the multiplier, since that field only applies to the second band of hours.
Overtime pay, $ applies the 1.5 multiplier to just those 10 extra hours: 20 times 1.5 times 10, or $300.00. Total weekly pay, $ combines the two bands into $1,100.00. That combination — 40 hours plus 10 hours priced at 1.5x for a $20 rate — mirrors the standard overtime arithmetic that covers most hourly employees, which is exactly why 1.5 is the multiplier's starting value even though the field stays open for the exceptions.
Questions
Why is the overtime multiplier editable instead of fixed at 1.5?
Because 1.5x is the federal floor, not the only rate paid in practice. Some employers owe double time for a holiday or a seventh consecutive workday under a contract, and a few states set daily overtime rates that run separately from the federal weekly one. Typing 2 into the field prices a double-time week with the same two formulas; typing any other contracted rate prices that instead, without needing a second calculator.
Does this calculator handle California's daily overtime rule?
No — this prices a week's total hours against the 40-hour mark, the standard most states use. California and a short list of others instead trigger overtime inside a single day, before the week ever gets close to 40. Pricing that kind of schedule needs an hour-by-hour breakdown of each shift; a single weekly multiplier cannot reproduce it.
What exactly goes in Regular hours versus Overtime hours?
Regular hours (up to 40) is the straight-time portion of the week, capped at 40; Overtime hours (beyond 40) is only the hours worked past that point, not the week's full total. A 45-hour week means 40 goes in the regular field and 5 in the overtime field — splitting the two correctly before entering them, rather than typing 45 into one box, is the step most likely to be missed.
Why does my actual paycheck differ from this result?
This is gross pay for one week's hours only, before tax withholding, and it assumes a single flat multiplier applies to every overtime hour. A real check can differ because of shift differentials, a bonus folded into the regular rate — which raises the true overtime base under federal rules — or a pay period that spans parts of two separate workweeks. Treat this as the underlying wage arithmetic, not the final net figure on a stub.
Does paid time off count toward the 40-hour threshold?
No — the Fair Labor Standards Act threshold counts hours actually worked in a single week, not hours paid. A worker who takes a paid holiday and then works 38 hours has not crossed 40, even though the paid week totals more than that. Only hours actually worked belong in the regular and overtime fields here.
Who actually uses a weekly overtime split like this one?
Payroll clerks running a fast gross-pay check without full payroll software, hourly employees comparing the result against their own timesheet, and managers estimating a week's labor cost before approving overtime. Because the multiplier is editable, the same instrument covers a standard 1.5x week and a contract's 2x holiday shift without switching tools.
