Estimate gross earnings for regular hours, time and a half, and a second premium rate such as double time. Enter your hours by rate, or let the weekly mode split one week at an editable overtime threshold.
How to calculate overtime pay
Choose Entered hours when your timesheet already separates regular and premium hours. Enter each hour in exactly one category. For example, five hours paid at double time belong in the second-rate field, not in both overtime fields. The result covers the hours entered; the base pay period is only used to establish an hourly equivalent.
Choose Weekly threshold when all hours above one weekly limit receive the same multiplier. A 45-hour week with a 40-hour threshold gives 40 regular hours and five overtime hours. A 35-hour week has no overtime under those settings. Daily thresholds, multiple weekly tiers, and holiday rules need to be classified separately in entered-hours mode.
Time and a half versus the extra premium
At a base rate of 20 per hour, time and a half pays 30 for each overtime hour. The extra premium is 10, not 30. This calculator shows both the full pay for overtime hours and the extra premium already included in that pay. Adding the premium to the total again would double count it.
Converting salary to an hourly estimate
For annual pay, divide by paid weeks per year and normal paid hours per week. Monthly pay is multiplied by 12 first. Daily pay is divided by normal hours per day, derived from the weekly schedule. The schedule fields do not decide which worked hours qualify for overtime.
A salary equivalent is useful for planning, but an employer's applicable regular rate can include other compensation. Bonuses, commissions, shift differentials, and particular salary arrangements are outside this simple model. Use the hourly input when you already know the appropriate base rate.
This is a gross-pay estimate. It does not decide overtime eligibility or calculate tax, benefits, daily overtime rules, or deductions. Use your applicable pay agreement and workweek rules for the inputs.
Why the defaults are 40 hours and 1.5 times pay
For covered, nonexempt workers, the US federal rule generally requires at least time and a half after 40 hours in a workweek. These editable defaults are an example, not a rule for every worker or country. See the US Department of Labor overtime fact sheet for coverage and regular-rate context.
Formula
Overtime rate = hourly base × multiplier
Gross pay = regular hours × base + overtime hours × overtime rate
Extra premium = overtime hours × base × (multiplier − 1)
Examples
Five hours at time and a half
With a base rate of 20, 40 regular hours and five hours at 1.5×, regular pay is 800 and overtime pay is 150. Total gross pay is 950. The included extra premium is 50.
Two overtime rates
At 20 per hour, 40 regular hours, five hours at 1.5× and two hours at 2× produce 800 + 150 + 80 = 1,030 gross pay.
Annual salary equivalent
Annual base pay of 52,000 over 52 paid weeks and 40 normal hours per week gives 25 per hour. At an agreed 1.5× multiplier, the estimated overtime rate is 37.50.
