Overtime Pay Calculator
This overtime pay calculator works out regular, time-and-a-half and double-time pay from your rate and the hours you worked.
Formula & worked example
Formula: Pay = regular hours × rate + overtime hours × rate × multiplier (+ double-time hours × rate × 2).
Example: 18 an hour, 52 hours, threshold 40, time and a half: 720 + 12 × 27 = 1,044 (about 20.08 an hour).
Method & source: Standard premium-pay method; US federal rule is 1.5× over 40 hours a week for most non-exempt employees. See how we test our calculators.
Next step: try hourly to salary or work hours with breaks.
Overtime Pay, Explained
An overtime pay calculator works out what you earn when you work more than your regular hours. It splits your hours into regular time and overtime, applies a premium such as time and a half, and adds them up into one total.
It also handles double-time hours and shows your effective hourly rate, so you can see what a long week is really worth.
Calculating Regular, Overtime and Double-Time Pay
Enter your hourly rate, the hours you worked, your regular-hours threshold and the overtime multiplier.
- Regular pay: hours up to the threshold multiplied by your hourly rate.
- Overtime pay: hours above the threshold multiplied by your rate and the overtime multiplier.
- Double time: optionally treat some overtime hours at twice the rate.
- Effective rate: total pay divided by all hours worked.
- Step-by-step working: every line of the calculation is shown.
The tool covers gross pay only. Tax and other deductions depend on your country and circumstances.
Why Checking Overtime Pay Matters
Overtime is easy to get wrong when rules differ between employers, contracts and countries.
- Check that your payslip includes the overtime you worked.
- See how much extra a shift at time and a half is worth.
- Plan whether extra hours are worth taking on.
- Compare regular, overtime and double-time pay side by side.
- Prepare figures before discussing pay with an employer.
Knowing how your overtime is calculated helps you spot errors and make better decisions about extra hours.
Worked walkthrough: a 52-hour week
A warehouse worker earns 18 an hour with overtime after 40 hours at time and a half. In a 52-hour week, regular pay is 40 × 18 = 720. The 12 overtime hours are paid at 18 × 1.5 = 27, adding 324, so total pay is 1,044 and the effective hourly rate is about 20.08. If 4 of those 12 hours fall on a Sunday paid at double time, the calculation becomes 8 × 27 = 216 plus 4 × 36 = 144, so overtime is 360 and the week totals 1,080, or about 20.77 an hour.
Practical tips for Overtime Pay calculations
- Check your contract or employee handbook for the regular-hours threshold – it may be daily, weekly or per pay period.
- In the US, the federal rule is 1.5 times the regular rate over 40 hours in a workweek for most non-exempt employees; some states add daily overtime rules.
- In the UK there is no general right to enhanced overtime pay, but the National Minimum Wage still applies to your average pay for hours worked.
- Enter double-time hours only for the hours that really qualify, such as bank holidays if your contract says so.
- Use the effective hourly rate to judge whether a very long week is worth the extra time.
Regular hours, overtime and double time
Overtime is pay for hours beyond a set threshold, usually paid at a premium. Time and a half means 1.5 times the normal rate, and double time means twice the rate, often for weekends, holidays or very long shifts. The calculator prices each band separately and adds them together, so you can see where the money comes from.
At a rate of 22 an hour with a 40-hour threshold, a 48-hour week pays 40 × 22 = 880 for regular hours plus 8 × 33 = 264 of overtime, a total of 1,144. If two of the extra hours are overtime and six are double time, the total is 880 + 66 + 264 = 1,210.
How time and a half is calculated
Time and a half is the normal hourly rate × 1.5, and double time is the rate × 2. The table shows both for three hourly rates, plus the gross pay for a 45-hour week with 40 regular hours and 5 hours at time and a half.
| Hourly rate | Time and a half (1.5×) | Extra per overtime hour | Double time (2×) | 45-hour week, 5 h at 1.5× |
|---|---|---|---|---|
| 12 | 18 | 6 | 24 | 570 |
| 15 | 22.50 | 7.50 | 30 | 712.50 |
| 20 | 30 | 10 | 40 | 950 |
At 15 an hour the week works out as 40 × 15 = 600 plus 5 × 22.50 = 112.50, a total of 712.50. The calculator lets you choose the overtime multiplier (time and a quarter, time and a half, time and three quarters or double time) and has a separate box for hours paid at double time; it does not pick a rate for you, because overtime rules differ by country, employer and contract. Self-employed? There is no overtime premium unless you charge one, so price extra hours with the freelance rate calculator.
The effective hourly rate
The effective rate is total pay divided by total hours, and it shows what an hour of your time is actually worth that week. The 48-hour week above pays 1,144, which is 23.83 an hour against a base rate of 22. The mixed week with double time pays 1,210 over 48 hours, or 25.21. Comparing the effective rate with your base rate shows whether taking extra shifts is worthwhile.
Overtime rules depend on where you work
There is no single overtime rule. In the United States, federal law generally requires 1.5 times the regular rate for hours over 40 in a week for most non-exempt employees, and some states add their own rules. In the UK there is no general statutory right to enhanced overtime pay, so it depends on your contract, although your average pay across all hours worked must still meet the National Minimum Wage. Check your contract or employee handbook for the threshold and multipliers that apply to you.
Overtime and tax
The gross overtime figure is before tax, and extra earnings can be taxed at your highest marginal rate, so the amount that reaches your bank account is lower than the headline. To estimate the net effect on a UK salary, use the UK take-home pay calculator with the higher total.
Salaried staff and unpaid extra hours
Many salaried roles include no overtime at all, so extra hours lower the effective rate instead of raising the pay. The hourly to salary calculator shows the hourly rate behind a salary for the hours you actually work, and the work hours calculator totals shifts and breaks before you enter them here.
Frequently Asked Questions (FAQs)
Multiply your hourly rate by the overtime multiplier and by the number of overtime hours, then add your regular pay. At 15 an hour, 46 hours worked, a 40-hour threshold and time and a half, total pay is 735.
It depends on where you work. In the United States the Fair Labor Standards Act requires most non-exempt employees to be paid at least 1.5 times their regular rate for hours over 40 in a workweek. In the UK there is no general legal right to enhanced overtime pay; it depends on your contract.
The number of hours you work before overtime starts. It might be 40 a week, 37.5 a week or a daily limit, depending on your contract.
No. It calculates gross pay. Use a take-home pay calculator to estimate what remains after deductions.
Multiply your hourly rate by 2, then by the double-time hours. At £15 an hour, 4 double-time hours pay £120.
Half as much again: each overtime hour pays 50% more than a normal hour. On a rate of 15, time and a half is 22.50 an hour, which is 7.50 extra; on 20 it is 30, which is 10 extra. Over 5 overtime hours at a rate of 15, that comes to 112.50 instead of 75 at the normal rate.
Yes. Enter hours at each rate and the calculator adds regular, overtime and double-time pay into one total.
It is total pay divided by total hours worked. The result shows it so you can see how overtime lifts your average pay.
Check your contract and local law. Overtime rules, thresholds and multipliers vary by country, state and employer. This tool calculates gross pay from the values you enter and is not legal or payroll advice. See our full disclaimer.
