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.

Hours & Pay

$
hFor the pay period, usually one week.
h40 is the US federal weekly threshold; UK contracts vary.
hOptional – for Sundays or holidays.

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.

What Is an Overtime Pay Calculator?

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.

How Our Overtime Pay Calculator Works

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.

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 means overtime hours are paid at 1.5 times your normal hourly rate. Double time is 2 times the rate.

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.

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.
