What this result does not account for
- Gross only — no withholding or benefits
- One rate and one multiplier per period
In short: A period of 160 regular hours plus 5 overtime at $25 an hour pays $4,187.50 gross — $4,000.00 of base plus $187.50 of premium at the $37.50 overtime rate. Across 165 hours that is an effective $25.378788 an hour, the premium pulling the average above the base. Gross is where this page stops on purpose: withholding, benefits and the actual cheque belong to the tax pages it links.
Formula
gross = regular × rate + overtime × rate × multiplier
The period prices in two lines: regular hours at the base rate, overtime hours at the multiplied rate. The effective rate divides the gross by every hour worked, regular and overtime alike — it is the single number a salaried comparison wants, and it is an average, not a rate anyone was paid. Withholding starts after this page ends.
Worked Example
- Enter regular hours, overtime hours, rate, multiplier.
- Read the gross and its two-line split.
- Check the effective hourly rate.
Defaults: 160 plus 5 at $25 and 1.5 — $4,187.50 gross, $187.50 of premium, $25.378788 effective across 165 hours. Drive the overtime to zero and the effective rate is the base rate exactly.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Payroll Hours Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
Why does the page stop at gross?
Because gross is arithmetic and take-home is policy: withholding, benefits and garnishments layer rules this page does not own. The take-home page prices the cheque; the overtime-tax page prices the premium's tax slice.
What is the effective rate for?
Comparing periods and offers: it folds the premium into one hourly figure, so a 165-hour month at $25 reads as $25.378788. It is an average over all hours — nobody was paid that rate, which is exactly why it compares cleanly.
How does the overtime premium enter?
As its own line: overtime hours times the rate times the multiplier. The split card shows base and premium separately, so a disputed multiplier is one number to argue, not five.
Where do the hours come from?
The timesheet. Log the week there, run the overtime split there if your contract has a threshold, and bring the totals here to price the period.
Can the period be a month, a fortnight, a year?
Any period you have hours for — the page prices hours, not calendar names. Annualize by entering annual hours; the effective rate normalizes the comparison either way.
Why refuse a zero-hour period?
A gross of $0.00 over zero hours has no effective rate — dividing by zero would invent one. The page refuses and says so rather than printing a meaningless average.
Does the multiplier have to be 1.5?
Enter what the contract says: 1.5, 2, or 1.25 for a premium that is not a clean half. The arithmetic holds any multiplier of 1 or more.
Is overtime mandatory in the calculation?
Set overtime hours to zero and the gross is the base line — the split card shows a $0.00 premium, which is the honest shape of a flat period.
