Separate regular earnings from overtime premium pay
For a straightforward hourly scenario, total weekly earnings equal regular hours at the base rate plus overtime hours at the selected premium multiplier.

Overtime is where paycheck surprises live in both directions. Workers counting on premium pay want to verify the multiplier actually applied, and schedulers want to know what a 45-hour week really costs. The federal baseline under the Fair Labor Standards Act is simple — covered nonexempt employees receive at least 1.5 times their regular rate for hours beyond 40 in a workweek — but the details around that rule trip people up constantly.
This calculator models the arithmetic clearly: enter the base rate, regular hours, overtime hours, and multiplier, and it separates the two earnings streams so you can see exactly what each contributes. The default 1.5× reflects the federal minimum; the field is editable for states with daily rules, union contracts with richer premiums, or employers that voluntarily pay 2×.
How the calculation works
Total pay = regular hours × hourly rate + overtime hours × hourly rate × multiplier
- Calculate regular earnings from regular hours and base rate.
- Multiply the base rate by the overtime multiplier.
- Multiply that overtime rate by overtime hours and add regular earnings.
Worked example
At $24 per hour, 40 regular hours plus 8 overtime hours at 1.5× produces $960 regular pay, $288 overtime pay, and $1,248 total weekly gross pay. Raise the multiplier to 2× and the overtime stream alone jumps to $384 — a $96 difference for the same hours, purely from the premium terms.
What this estimate does not include
- This is a simple hourly-pay estimate, not a determination of legal eligibility.
- Bonuses and other compensation can affect the legally defined regular rate.
- State rules, exemptions, union terms, and alternative schedules can change overtime treatment.
Use the result as a planning estimate, not as personalized financial, tax, legal, or investment advice.
