How Overtime Pay Is Calculated

Overtime pay is your base hourly rate multiplied by an overtime premium for every hour beyond the normal schedule. At the common time-and-a-half rate, a 25.00 base rate becomes 37.50 per overtime hour, so 40 regular hours plus 5 overtime hours pays 1,000.00 plus 187.50, a total of 1,187.50. The calculator also shows your effective hourly rate across all hours worked, which is useful when comparing a salaried offer against an hourly job with regular overtime.

The 1.5x multiplier is the legal minimum for hours over 40 per week for non-exempt employees in the United States under the Fair Labor Standards Act, and 2x double time is common for holidays, seventh consecutive workdays, or hours beyond 12 in a day in some jurisdictions such as California. Many European countries instead regulate overtime through collective agreements: multipliers of 1.25x for the first bracket and 1.5x beyond are typical in Dutch and German agreements, and some contracts compensate with time off rather than money.

Because rules differ that much, the multiplier field is fully editable and there is a separate line for double-time hours, so you can model a week that mixes normal overtime and holiday work. Salaried employees can still use the tool: divide your gross annual salary by 52 weeks and your contract hours to get an equivalent hourly rate, then check what the extra hours you are actually working would be worth if they were paid.

Treat the result as an indication, not a payroll statement: taxes, social contributions, shift allowances, and rounding rules in your payroll system will change the net outcome. To first build the hours themselves from start and end times, use the Timesheet Calculator, and to see what an annual figure means per month or per hour, the Salary Calculator converts between pay periods.

How the Overtime Calculator Works

  1. 01Enter your base hourly rate and adjust the overtime multiplier (1.5x by default).
  2. 02Fill in regular hours, overtime hours, and any double-time hours.
  3. 03The tool multiplies each bucket by its rate and adds them up.
  4. 04Read regular pay, overtime pay, double-time pay, total, and your effective hourly rate.

Using Overtime Multipliers Correctly

Time and a half (1.5x) is the most common overtime premium, but it is not universal: some agreements start at 1.25x for the first overtime bracket, and double time (2x) often applies to holidays or very long days. Enter the hours in the matching bucket and adjust the multiplier to whatever your contract or collective agreement specifies. The effective rate line shows what your blended hourly earnings are across all hours worked.

When to Use an Overtime Calculator

Use it when checking a payslip after a week with extra hours, when deciding whether picking up an extra shift is worth it, or when comparing a salaried job against an hourly one with regular overtime. It is also useful for employers making a quick estimate of what an extra project week will cost in wages.

Common Use Cases

Tips

  • Use the 1.25x / 1.5x / 2x quick buttons to switch between common premiums.
  • Keep holiday hours in the double-time field so they are not mixed with normal overtime.
  • Salaried? Divide annual gross by (52 x contract hours) to get an hourly rate to test with.

Frequently Asked Questions

What is time and a half?→
Time and a half means each overtime hour pays 1.5 times your base rate. At a 20.00 base rate, an overtime hour pays 30.00. Working 5 overtime hours on top of a 40-hour week at that rate adds 150.00 to your gross pay.
When does double time apply?→
Double time (2x) commonly applies to public holidays, Sundays in some industries, or extreme hours, such as beyond 12 hours in a single day under California law. Many countries have no statutory double time at all and leave it to collective agreements, so check your contract.
Is overtime pay required by law?→
It depends on where you work and your role. In the US, non-exempt employees must get at least 1.5x for hours over 40 per week under the FLSA. In much of Europe, overtime compensation comes from collective agreements and can be paid time, extra pay, or both. Salaried and managerial roles are often exempt.
What does the effective hourly rate mean?→
It is your total gross pay divided by total hours worked. If you work 40 regular hours plus 10 overtime hours at 1.5x, your effective rate is 1.1 times your base rate. It is a fair way to compare jobs with different overtime patterns.
Does the result include taxes?→
No, all amounts are gross. Overtime is taxed as normal income in most countries, although a higher gross in one month can temporarily push more of it into a higher withholding bracket. Net effects depend entirely on your local tax rules.
