Overtime Calculator
This overtime pay calculator applies time and a half rules using an editable weekly threshold and multiplier, plus optional gross pay before deductions calculation.
Separate the weeks, then the hours
A busy week and a short week do not cancel each other out under a weekly overtime rule. Each week is calculated independently.

How the Selected Threshold Applies to Each Week Separately
A custom weekly threshold is applied to each complete weekly total, not to the combined pay-period total. Weekly overtime is different from pay-period boundaries; two weekly totals are assessed separately even when shown in one two-week report. This calculation does not include daily overtime rules. Default thresholds are only starting values for illustration and are not universal legal rules, so users must check controlling law and employer policy.
Total Hours Versus Overtime Hours
Total hours and overtime hours answer different questions. Total hours are the sum of all hours entered across the selected one-week or two-week period. Regular hours and overtime hours split that total according to the selected threshold for each week. Under a selected 40-hour threshold, entering 50 hours for week one and 30 hours for week two yields 80 total hours, 70 regular hours, and 10 overtime hours. The first week contributes 40 regular hours plus 10 overtime hours, while the second week contributes 30 regular hours and no overtime. Unworked time is not automatically counted unless you include it in the weekly entry. Keeping total, regular, and overtime hours visible helps check data entry, compare weeks, and understand why two weeks with the same total can produce different overtime results.
Simple Time-and-Half Arithmetic
The simple pay estimate uses straightforward time and a half arithmetic when an optional base rate and multiplier are supplied. The overtime rate equals the simple base rate multiplied by the multiplier. For example, a simple base rate of 20 multiplied by 1.5 gives an overtime rate of 30. Regular pay equals regular hours multiplied by the base rate, and overtime pay equals overtime hours multiplied by the overtime rate. With 40 regular hours and five overtime hours at those rates, regular pay is 800, overtime pay is 150, and the simple gross amount is 950. The multiplier can be changed for what-if comparison, but changing it does not determine legal entitlement. This arithmetic stays intentionally simple and does not add bonuses, shift differentials, or blended rates.
Gross Estimate Versus Take-Home Pay
The simple gross example uses 40 regular hours plus 5 overtime hours at a 20 base rate with a 1.5 multiplier. Regular pay is 800, overtime pay is 5 times 30, or 150, for a combined gross of 950. This is gross pay only; taxes, deductions, net pay, bonuses, and other premiums are not included. It also does not determine the legally required regular rate, which can involve additional payments and rules outside this arithmetic. A pay statement can be compared line by line against hours and rates as useful evidence, but a printed amount does not by itself establish that the payment was legally correct.
Regular-Rate and Coverage Limitations
This calculator uses only the simple base rate you enter and does not determine the legal regular rate. It does not handle bonuses, commissions, piece rates, multiple pay rates in one week, retroactive pay changes, or variable-rate legal regular-rate calculations. United States federal references here concern generally covered nonexempt work, but coverage depends on duties, salary basis, industry, employer size, and specific exceptions. The commonly shown 40-hour threshold and 1.5 multiplier defaults are examples only, not rules for every country, state, contract, or worker. This calculator does not label everyone paid hourly as nonexempt or everyone salaried as exempt. Under the federal framework discussed here, weekend or holiday work does not automatically create overtime; only hours beyond the applicable weekly threshold do.
Biweekly Overtime Examples
Biweekly overtime examples show why each week must be checked separately. With a selected 40-hour threshold, 40 hours in week one and 40 hours in week two produce 80 total hours and zero overtime hours. With 50 hours in week one and 30 hours in week two, the total is also 80 hours, but the result is 70 regular hours and 10 overtime hours. With 45 hours in both weeks, the total is 90 hours, with 80 regular hours and 10 overtime hours. Averaging across the pay period would give the wrong answer in the uneven example because the lower week cannot offset the higher week. These time and a half and biweekly overtime illustrations use the same threshold logic as the single-week calculation, repeated once for each week.
Record-Verification Checklist
Use a short record-verification checklist before relying on any weekly or biweekly figure. Confirm that each weekly entry uses the intended decimal or H:MM format, especially values such as 8:30 versus 8.3. Confirm that the selected threshold matches the scenario being tested and that one-week or two-week selection matches the hours entered. Compare total hours to source timesheets, time clocks, or schedules, then confirm the regular and overtime split for each week. Confirm that any simple base rate and multiplier are entered as what-if estimates only. Keep copies of original time records, corrections, meal-period rules, rounding rules, and final pay statements. If anything differs, correct the source hours first, then recalculate rather than editing only the result.
Questions, answered
How does this overtime calculator apply a custom threshold when two weeks are entered?
It applies the selected threshold separately to each weekly entry and does not average the pay period. Overtime threshold and pay-period duration are distinct, so a biweekly pay period still needs two weekly checks. Weekly hours may be entered as decimal hours or H:MM, and the one-week or two-week setting should match the hours entered.
Why do 50 hours plus 30 hours produce 70 regular hours and 10 overtime hours?
Under a selected 40-hour threshold, the first week gives 40 regular hours plus 10 overtime hours, while the second week gives 30 regular hours and no overtime. The combined result is 80 total hours, split into 70 regular hours and 10 overtime hours. Equal totals can therefore produce different overtime outcomes.
How is time and a half calculated in the simple estimate?
The overtime rate equals the simple base rate times the multiplier. A simple base rate of 20 times 1.5 gives an overtime rate of 30. With 40 regular hours and five overtime hours, regular pay is 800, overtime pay is 150, and the simple gross amount is 950.
Is the simple gross amount the same as take-home pay?
No. The calculator provides a simple gross estimate before deductions. It does not calculate taxes, withholding, benefits, or net paycheck amounts. Use payroll records and the pay statement for amounts after deductions and corrections.
Does weekend or holiday work automatically create federal overtime?
No. Under the federal framework discussed here, only hours beyond the applicable weekly threshold create overtime. Weekend or holiday timing alone does not create overtime. Coverage also depends on nonexempt status and specific exceptions, not simply on being paid hourly or salaried.
What is excluded from this calculator?
It excludes daily overtime, bonuses and other incentive pay, variable-rate legal regular-rate calculations, multiple rates in one week, taxes and net pay, and rules for every country or contract. The 40-hour and 1.5 defaults are examples for what-if calculation, not universal legal requirements.
