At $20 per hour, 40 regular hours produce $800.00 and 5 overtime hours at 1.5x produce $150.00, for estimated gross pay of $950.00.
The rate used before the overtime multiplier.
Pay for regular hours at the base rate.
Pay for overtime hours after applying the multiplier.
The extra amount above base-rate pay for overtime hours.
Regular hours plus overtime hours in this estimate.
Gross pay divided by all regular and overtime hours.
Overtime pay formula used
$20.00 x 40 + $20.00 x 5 x 1.5 = $950.00How this result was calculated
- Use the $20.00 base hourly rate for the 40 regular hours.
- Multiply $20.00 by 1.5 and 5 overtime hours to get $150.00.
- Add $800.00 regular pay and $150.00 overtime pay.
- Divide $950.00 by 45 total hours to show a $21.11 effective hourly rate.

$28 per hour, 36 regular hours, and 6 overtime hours at 2x.
How to use this overtime calculator
The tool separates regular pay from the overtime premium so you can review the assumptions instead of seeing only one final number.
Choose the pay basis
Select hourly rate when you know it, or weekly salary to add overtime to a fixed base.
Enter the hours
Enter regular and overtime hours for one pay period; do not count the same hour twice.
Set the multiplier
Use 1.5 for time and a half, 2 for double time, or a documented alternative.
Review the breakdown
Check regular pay, overtime pay, premium, total hours, and effective hourly pay.
What to enter in an overtime pay calculator
Use one pay period and one consistent pay basis. A weekly salary should match that week's regular and overtime hours; an hourly rate should be the rate used for the same work. Do not mix a weekly rate with biweekly hours.
The multiplier controls the premium: 1.5 pays 150% of the base rate and 2 pays 200%. The tool does not decide eligibility, the regular rate, included bonuses, breaks, rounding, commissions, or multiple-rate rules. Check the written policy or pay statement.
| Input | What to enter | How the tool uses it |
|---|---|---|
| Hourly rate | $20.00 | Uses the amount as the base rate for regular and overtime calculations. |
| Weekly salary | $1,200.00 | Divides the weekly base by regular hours to estimate the implied hourly rate. |
| Regular hours | 40 | Calculates regular pay at the base or implied hourly rate. |
| Overtime hours | 5 | Calculates pay at the base rate multiplied by the overtime multiplier. |
| Multiplier | 1.5 | Sets time and a half, double time, or another documented premium. |
Overtime calculator formulas
These equations keep the estimate transparent. They describe arithmetic, not a legal determination of overtime eligibility or a promise about take-home pay.
Base hourly rate
base hourly rate = hourly rateFor a weekly salary basis, the tool estimates base hourly rate as weekly salary divided by regular hours. That assumption is shown in the result context.
Regular pay
regular pay = base hourly rate x regular hoursA weekly salary basis treats entered salary as regular pay for the period.
Overtime pay
overtime pay = base hourly rate x overtime hours x multiplierAt 1.5x, each overtime hour pays 150% of the base rate; at 2x, it pays 200%.
Gross and effective pay
gross pay = regular pay + overtime pay; effective rate = gross pay / total hoursGross pay is before deductions; effective rate averages gross pay over all hours.
How to read an overtime calculator result
Regular pay covers the base schedule. Overtime pay applies the multiplier to overtime hours. Premium isolates the extra amount above base-rate pay; in the default example, 5 hours would be $100 at base rate versus $150 at 1.5x, a $50 premium.
Effective hourly rate averages gross pay across all hours. It helps compare scenarios but is not a contract rate and says nothing about taxes or benefits.
Weekly salary mode assumes salary covers regular hours and overtime is added using the implied rate. Bonuses, commissions, exemptions, or employer-specific regular-rate rules may require a different calculation.
| Result | Meaning | Useful for |
|---|---|---|
| Regular pay | Base-rate pay for regular hours. | Checking the ordinary portion of a weekly wage estimate. |
| Overtime pay | Pay for overtime hours after the multiplier. | Comparing time-and-a-half, double-time, or another documented rate. |
| Overtime premium | Extra pay above base-rate treatment of overtime hours. | Seeing how much the premium contributes to gross pay. |
| Effective hourly rate | Gross pay divided by all hours in the scenario. | Comparing scenarios with different regular and overtime hours. |
Overtime calculator limits and edge cases
Use these boundaries to decide whether the simple estimate matches your pay arrangement or whether you need a payroll-specific calculation.
No overtime
Enter 0 to calculate regular pay only.
Time and a half
1.5 means 150% of the base rate; verify it applies to these hours.
Double time
2x doubles the base rate; it may apply only to a specific shift or agreement.
Weekly salary
Salary mode infers a rate from salary divided by regular hours; it does not decide exempt status.
Multiple rates
For multiple jobs, shifts, commissions, or bonuses, use the documented regular-rate method.
Taxes and deductions
Gross only; taxes, benefits, retirement, garnishments, and corrections are excluded.
A note about payroll rules
This is an arithmetic planning tool. U.S. overtime eligibility and the regular rate can depend on classification, workweek, included compensation, exemptions, state law, and employer policy. Review official U.S. Department of Labor guidance and your pay documents before using an estimate for a dispute or filing.
For a paycheck comparison, check the workweek, threshold, multiplier, rounding, and deductions. For a wage claim or compliance question, consult a qualified payroll or employment adviser.
Review the U.S. Department of Labor overtime guidance for federal context, then confirm the rules that apply to your work arrangement.
