Purpose and steps
Premium hours = max(total weekly hours − threshold, 0). Weekly gross pay = non-premium hours × regular rate + premium hours × regular rate × overtime multiplier. Annualize using the entered weeks. The calculation runs locally and keeps cash-flow timing consistent with the stated assumptions.
- Confirm currency and monthly versus annual amounts. U.S. tax and loan models should be used within their stated scope.
- Prepare Regular hourly rate, Regular hours this week, Additional hours this week, Weekly overtime threshold, Overtime multiplier, Weeks with this schedule. Defaults demonstrate the model rather than your personal circumstances.
- Check the headline result and its components. A key interpretation for this tool is: Federal defaults apply to covered nonexempt employees; not everyone is eligible for overtime.
- Compare the baseline with a changed scenario: Enter the applicable threshold and multiplier if your contract or rules differ.
Input reference and units
These values reproduce the model’s demonstration. Replace them with your own records or measurements; they are not recommended targets.

| Parameter | Demonstration value | How to enter it |
|---|---|---|
| Regular hourly rate | 25 USD | Use dollars and the monthly or annual period stated in the field label; do not enter thousands of dollars. |
| Regular hours this week | 40 hours | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
| Additional hours this week | 10 hours | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
| Weekly overtime threshold | 40 hours | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
| Overtime multiplier | 1.5 times | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
| Weeks with this schedule | 52 weeks | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
Model-specific method
How this calculator produces its result
Premium hours = max(total weekly hours − threshold, 0). Weekly gross pay = non-premium hours × regular rate + premium hours × regular rate × overtime multiplier. Annualize using the entered weeks.
Linear accumulation and proportional units
Linear accumulation adds the same increment each period. It differs from compound growth because the base does not increase after a previous gain. Multiplication also converts a rate such as dollars per hour into an amount when the time units cancel.
Do not mix a yearly rate with a count of months without converting months to years. Likewise, 52 paid weeks is an assumption rather than a guarantee of annual wages. Overtime models need separate regular and premium hours; otherwise a blended hourly rate can obscure how the total was formed.
I = P × r × t; total = P + I Annual wage = hourly wage × hours/week × paid weeks/year
- P: fixed base
- r: rate expressed as a decimal
- t: duration in the rate’s unit
- For wages, unpaid weeks must be excluded
Worked example
At $25 an hour, 40 regular hours and 10 extra hours with a 40-hour threshold and 1.5 multiplier pay $1,000 regular plus $375 overtime, for $1,375 weekly gross pay.
Reproduce the default scenario
This is a separate example, calculated using the exact engine on the tool page and the defaults in the input reference above. Health examples use metric units. Displayed rounding may differ from intermediate precision.
- Weekly gross pay
- 1,375 USD
- Straight-time pay
- 1,000 USD
- Overtime pay
- 375 USD
- Premium-eligible hours
- 10
- Overtime hourly rate
- 37.5 USD
- Annual gross pay at this schedule
- 71,500 USD
- Extra pay above straight-time rate
- 125 USD
Reading results without overstating them
- Federal defaults apply to covered nonexempt employees; not everyone is eligible for overtime.
- Enter the applicable threshold and multiplier if your contract or rules differ.
Assumptions and exclusions
- This is a simple hourly, weekly model, not a determination of legal entitlement. It does not implement state daily overtime, double time, exemptions, bonuses in the regular-rate calculation, or special industry rules.
