Overtime Calculator

Estimate gross pay for one workweek at one base hourly rate. Enter a weekly threshold or hours already classified into non-overlapping pay bands; check the rules that apply to the worker separately.

CurrencyUse one currency for all amounts. This changes labels only; it does not convert money or change local rules.

How will you enter hours?

Base straight-time hourly payUSD/hourOne hourly rate for all hours in this model. A zero entry is permitted for arithmetic, not a wage-compliance conclusion.

Total hours actually workedhoursOne workweek only. Do not average multiple weeks or include paid leave as hours worked.

Entered weekly overtime thresholdhours40 is an illustrative US federal baseline for covered, nonexempt workers—not a global or universal rule.

Overtime pay multiplier× regular rate1.5 means time-and-a-half total pay, not an additional 150% premium.

How to use this calculator

Use one workweek

Enter actual worked hours for one weekly period. Determine coverage, exemptions and any more protective requirements outside this tool.

Set the hour classification

Weekly mode places hours above your entered threshold in the overtime band. Manual mode trusts your separate, non-overlapping regular, overtime and other-band hours.

Check the regular-rate inputs

This model uses one base rate and optionally spreads an included, week-allocated bonus over all worked hours. Multiple job rates and complex bonus allocations require a separate calculation.

Read gross pay and premium separately

Straight-time earnings and the entered bonus already pay the base portion. The additional premium is only multiplier minus one, avoiding double-counting that portion.

Formula and worked example

Weekly mode: overtime hours = max(0, worked hours − entered threshold)
Straight-time earnings = base hourly pay × all worked hours
Modeled regular rate R = (straight-time earnings + included weekly bonus) ÷ worked hours
Additional overtime premium = R × (overtime multiplier − 1) × overtime hours
Other-band premium = R × (other multiplier − 1) × other-band hours
Gross modeled pay = straight-time earnings + included bonus + both additional premiums

At 20 per hour for 45 worked hours, a 40-hour threshold and 1.5 multiplier produce 900 straight-time earnings plus 50 additional premium, totaling 950 gross. This is also 800 for the first 40 hours plus 150 for the five overtime hours. If an additional 100 bonus belongs in this workweek’s regular rate, that rate becomes 1,000 ÷ 45; the premium becomes about 55.56 and gross pay about 1,055.56.

Frequently asked questions

Is this an overtime eligibility checker?

No. It applies the threshold and multipliers you enter. Exemptions, jurisdiction, worker classification and applicable agreements need separate review.

Why are overtime pay and extra premium different?

The full overtime rate includes both the base portion and the extra premium. When straight-time earnings have already been counted for all hours, only the extra premium is added again.

Can a bonus affect the modeled overtime rate?

Yes. An included bonus allocated to this workweek increases the modeled regular rate. Whether a payment belongs in that rate is a separate classification question; its label alone is not enough.

Does it automatically apply daily overtime or double time?

No. Manual mode accepts hours you have already classified into separate bands. It does not decide daily thresholds, seventh-day rules or how overlapping premium rules interact.

Is this take-home pay?

No. It excludes withholding, payroll taxes, deductions, benefits and payments outside the included bonus input. It is not a payslip or a legal determination of wages owed.

Methodology and sources

One workweek, one hourly base rate and non-overlapping hours totaling at most 168. The optional bonus is spread uniformly over that week’s worked hours; zero hours with an included bonus is rejected. Excludes salary-method calculations, multiple hourly rates, piecework, retroactive multiweek bonuses, excluded payments and jurisdiction-specific classifications. Defaults are examples; applicable wage requirements cannot be changed by editing a calculator.
