Overtime calculator

Enter your hourly rate, the hours you worked and the hours after which overtime starts. The calculator splits regular and overtime hours and gives you the total pay, with every step shown.

A simple example: overtime after 40 hours paid at 150%.

This calculator gives an estimate and is not legal, tax or employment advice. The presets are examples: your contract, collective agreement and local law determine the real values.

How to use it

  1. Choose a starting point. Pick a country to fill in a typical threshold and premium, or keep the generic example. These are examples only: your contract decides.
  2. Enter rate and hours. Type your hourly rate and the total hours worked in the period, as a decimal number (45.5 for 45 hours 30 minutes).
  3. Set the threshold and premium. The threshold is the number of regular hours in the period, often 40 per week. The overtime pay is a percentage of your rate: 150 means time and a half.
  4. Read the breakdown. You see overtime hours, the pay for each part and the total. Switch on the second level if hours beyond a higher threshold are paid at a higher rate.

How overtime pay is calculated

Overtime is work beyond the regular hours of a period, usually a week. Hours up to the threshold are paid at the normal hourly rate; hours above it are paid at the rate multiplied by the overtime percentage. The calculation has three steps.

  1. Regular hours = the smaller of the hours worked and the threshold. Regular pay = regular hours × hourly rate.
  2. Overtime hours = hours worked above the threshold. Overtime pay = overtime hours × hourly rate × overtime percentage ÷ 100.
  3. Total pay = regular pay + overtime pay. If a second level applies, hours beyond it are paid at their own percentage.

Time and a half means a multiplier of 1.5, entered here as 150%. Double time is 200%. A premium of 25% on top of the normal rate is entered as 125%.

Each amount is rounded to the cent and the total is the sum of the rounded parts, so the lines you see always add up to the total.

Worked examples

Time and a half

Rate 20, 45 hours in the week, regular hours 40, premium 150%. Regular pay is 40 × 20 = 800.00. Overtime is 5 hours at 20 × 1.5 = 30, which is 150.00. Total pay is 950.00, an average of 21.11 per hour worked and 50.00 more than paying all 45 hours at the normal rate.

Double time after a second threshold

Rate 20, 52 hours, regular hours 40 at 150% and a second level from 48 hours at 200%. Hours 41 to 48 are 8 overtime hours at 30 = 240.00. The 4 hours beyond 48 are paid at 40 = 160.00. With 800 of regular pay the total is 1,200.00.

Under the threshold

Rate 15 and 32.5 hours worked with a 40-hour threshold: no overtime. Total pay is 32.5 × 15 = 487.50.

Romanian premium of 75%

If overtime is paid rather than taken as time off, Romanian law sets a premium of at least 75% of base pay, entered as 175%. At a rate of 40 and 48 hours with a 40-hour threshold: 40 × 40 = 1,600.00 plus 8 × 40 × 1.75 = 560.00, total 2,160.00.

What the rules look like in different countries

Overtime rules are set by law, by collective agreements and by individual contracts, and they change. The summary below is for orientation only; check the current text that applies to you.

CountryIn general
United StatesThe federal Fair Labor Standards Act requires at least time and a half for hours over 40 in a workweek for non-exempt employees. Some states add daily overtime. Many salaried professionals are exempt.
United KingdomThere is no statutory overtime premium. Overtime pay is whatever the contract says. The Working Time Regulations limit the average week to 48 hours unless you opt out.
GermanyOvertime is set by the contract or the collective agreement. The Working Hours Act limits the working day to 8 hours, extendable to 10 if the average over six calendar months or 24 weeks stays at 8.
FranceThe legal premium is 25% for the first eight overtime hours in a week and 50% beyond, unless a collective agreement sets a different rate, which cannot be below 10%.
SpainOvertime must be paid at least at the value of an ordinary hour or compensated with time off. The annual limit is 80 overtime hours, not counting hours compensated with rest within four months.
ItalyPremiums come from the national collective agreement (CCNL) and company rules, and vary by sector, time of day and holidays. The legal average weekly limit, overtime included, is 48 hours.
RomaniaOvertime is compensated with paid time off within 90 days; if that is not possible it is paid with a premium of at least 75% of base pay. The weekly limit, overtime included, is 48 hours on average.

Getting an accurate figure

  • Use gross hourly rate. Divide your gross monthly pay by the hours you are paid for to get it. For a salary, divide the annual amount by 52 weeks and by the contract hours per week.
  • Count only paid hours. Subtract unpaid breaks first. The hours worked calculator does this for you.
  • Convert hh:mm to decimals. 38 hours 45 minutes is 38.75. Use the hours and minutes to decimal converter if you need it.
  • Check the period. The threshold must match the period you enter: 40 for a week, about 173 for a month of 40-hour weeks.

This is not a payroll or legal tool. Taxes, social contributions, night and holiday premiums and contract-specific rules are not included.

Frequently asked questions

How do I calculate overtime pay?
Multiply the hours above the threshold by your hourly rate and by the overtime percentage divided by 100, then add the pay for the regular hours. At 20 an hour, 5 overtime hours at time and a half give 5 × 20 × 1.5 = 150.
What does time and a half mean?
That each overtime hour is paid at 1.5 times the normal rate, a premium of 50%. In the calculator you enter 150. Double time is 200.
How do I calculate overtime for a salaried employee?
First find the hourly rate: annual salary ÷ 52 ÷ contract hours per week. Then enter that rate. Whether a salaried employee is entitled to overtime depends on the country, the contract and, in the United States, whether the role is exempt.
Is the weekly overtime threshold always 40 hours?
No. 40 is common in the United States and many other countries, but contracts can set 35, 37.5 or 38 hours, and some countries count overtime per day or per month. Enter the threshold that matches your period.
Are breaks included in the hours worked?
Only paid breaks count. Subtract unpaid breaks before entering the hours.
Can this calculator replace payroll software?
No. It shows how overtime pay works and gives a quick estimate. It does not include taxes, contributions or the special rules of your contract.
