Overtime Paycheck Calculator
The overtime paycheck calculator estimates gross pay for a paycheck that includes both regular hours and premium-rate overtime hours. It is different from a simple overtime-rate tool because it frames the answer as a paycheck for a selected pay period: weekly, biweekly, or monthly. the inputs multiplies regular hourly pay by regular work time, multiplies that hourly pay by the overtime multiplier to find the overtime rate, multiplies by overtime hours, and then adds both pieces. It also shows overtime as a share of total pay so you can see how dependent the check is on extra hours.
This is a gross-pay calculator. It does not predict the net amount deposited in your bank account, and it does not decide whether the hours are legally overtime. Under the federal Fair Labor Standards Act, many covered nonexempt employees must receive overtime pay at not less than one and one-half times the regular rate for hours worked over 40 in a workweek. Paychecks, however, often cover more than one workweek. A biweekly paycheck can include one week with overtime and one week without; federal overtime is generally evaluated by workweek, not by averaging the whole two-week period.
How to use this calculator
Enter your regular hourly pay before deductions. Enter regular work time for the pay period shown, then enter the overtime pay multiplier and overtime hours for that same period. Finally choose the pay period label. The label changes the wording of the result; it does not multiply or convert your hours. If you select “monthly,” enter monthly regular and overtime hours. If you select “biweekly,” enter the combined hours for the full two-week check.
For a flexible weekly overtime estimate, use the overtime calculator. For a fixed 1.5 times rate, use the time and a half calculator. If the same overtime pattern repeats and you want annual income, use the salary with overtime calculator or hourly to salary with overtime calculator.
Formula
The calculator follows these steps:
If total pay is zero, the calculator shows an overtime share of zero rather than dividing by zero.
Checking an overtime paycheck scenario
Use the default inputs: $20 per hour, 40 regular hours, 1.5× overtime multiplier, 4 overtime hours, and weekly as the pay period.
| Step | Calculation | Result |
|---|---|---|
| Regular pay | $20 × 40 hr | $800.00 |
| Overtime rate | $20 × 1.5 | $30.00 per hr |
| Total overtime pay | $30.00 × 4 hr | $120.00 |
| Total pay per week | $800.00 + $120.00 | $920.00 |
| Overtime share | $120.00 ÷ $920.00 × 100 | 13.04% |
| Total hours | 40 hr + 4 hr | 44 hr |
That matches the calculation exactly: the primary result is total pay per week of $920.00, with regular pay of $800.00, an overtime rate of $30.00/hr, total overtime pay of $120.00, overtime share of 13.04%, and 44 total hours.
FLSA and paycheck timing
The FLSA overtime rule is based on the workweek. That matters for paycheck review. A biweekly check with 84 total hours is not automatically four overtime hours. It could be 42 hours in each week, 44 in one week and 40 in the other, or 50 in one week and 34 in the other. Those patterns produce different overtime obligations under the federal weekly rule. This calculator can still total the paycheck once you know regular and overtime hours, but it does not reconstruct the weekly timesheet.
Exempt versus nonexempt status also matters. A salaried nonexempt employee may still have overtime computed from a regular rate. A salaried exempt employee generally is not owed FLSA overtime if the exemption is valid. Some states and localities have more protective wage-and-hour rules, and some employers provide premiums beyond the legal minimum. Always use the rule that actually applies to your job and location.
Tips for checking a paycheck with overtime
- Compare the calculator’s regular pay and overtime pay with separate lines on your paystub.
- Enter gross hourly pay, not the net hourly value after taxes.
- If the pay period is biweekly, make sure overtime hours came from weekly calculations.
- Do not include reimbursements or tips unless payroll treats them as part of the regular rate.
- Treat overtime-heavy checks carefully in a budget because the same hours may not repeat.
- If your result is close but not exact, ask whether payroll rounded hours or used an adjusted regular rate.
For budgeting after you estimate gross pay, the budget calculator helps assign overtime income to bills, debt, savings, and taxes. For wage comparisons after a raise, the pay raise calculator can show how a higher base rate changes future overtime.
