What Overtime Calculator does
Overtime pay is the hourly rate times a multiplier times the overtime hours. At 20 an hour, time and a half is 30 an hour, so 10 overtime hours earn 300; added to 800 for 40 regular hours, the week pays 1,100 and averages 22.00 an hour. This calculator does that sum for any rate, with a multiplier from 1.25x to 3x and a separate box for hours paid at double time. It shows regular pay, overtime pay, the overtime rate, the total and the effective hourly rate. You decide which hours count as overtime, because that rule depends on where you work and what your contract says.
Overtime pay formula
Overtime rate = Hourly rate × Multiplier Overtime pay = Overtime rate × Overtime hours Regular pay = Hourly rate × Regular hours Double-time pay = Hourly rate × 2 × Double-time hours Total pay = Regular pay + Overtime pay + Double-time pay Effective hourly rate = Total pay ÷ Total hours
Each line of pay is rounded to two decimals, and the total is the sum of those rounded lines, so the breakdown always adds up. The overtime rate itself is not rounded before it is multiplied by the hours: 17.33 an hour at 1.5x is 25.995, and ten hours of it pay 259.95 rather than 260.00. The Overtime rate box shows up to four decimals for that reason.

The time and a half and double-time rate for common hourly rates, with gross pay for a 50-hour week made of 40 regular hours and 10 overtime hours at 1.5x.

With 40 regular and 10 overtime hours at 1.5x, the effective rate is always 10% above the hourly rate, whatever the rate is.
What extra overtime hours add at 20 an hour
Each row is 40 regular hours at 20 an hour plus the overtime hours shown. Regular pay is 800.00 in every row.

Worked overtime examples
A rate that does not multiply evenly
Hourly rate 17.33, Regular hours 40, Overtime hours 10, Overtime multiplier 1.5x
Regular pay 693.20, Overtime pay 259.95, Total pay 953.15, Overtime rate 25.995, Effective hourly rate 19.06
Rounding the overtime rate to 26.00 first would overstate the pay by 5 cents.
A full shift paid at double time
Hourly rate 25, Regular hours 40, Overtime hours 8, Overtime multiplier 2x
Regular pay 1,000.00, Overtime pay 400.00, Total pay 1,400.00, Overtime rate 50.00, Effective hourly rate 29.17
Time and a half and double time in the same week
Hourly rate 20, Regular hours 40, Overtime hours 8, Overtime multiplier 1.5x, Double-time hours 4
Regular pay 800.00, Overtime pay 240.00, Double-time pay 160.00, Total pay 1,200.00, Effective hourly rate 23.08
The premium note reports that 52 hours at the plain rate would pay 1,040.00, so overtime added 160.00.
A 37.5-hour contract with time and a quarter
Hourly rate 22.50, Regular hours 37.5, Overtime hours 6.25, Overtime multiplier 1.25x
Regular pay 843.75, Overtime pay 175.78, Total pay 1,019.53, Overtime rate 28.125, Effective hourly rate 23.30
When does overtime start? It depends on where you work
This page multiplies the hours you give it. It does not decide which of your hours are overtime, because that is a legal and contractual question with different answers in different places.
In the United States, the federal Fair Labor Standards Act, as described by the Department of Labor, requires covered, non-exempt employees to be paid at least one and a half times their regular rate for hours worked over 40 in a workweek. Many salaried and other exempt roles are outside that rule. Some states add their own requirements, including overtime counted by the day rather than the week, and a state rule can be more generous than the federal one.
Outside the United States the picture changes again. Some countries set a legal premium, some leave the rate to the employment contract or a collective agreement, and some allow time off in place of extra pay. Weekend, night and public holiday work is often paid at its own rate, which is what the 2x, 2.5x and 3x options and the double-time box are for.
Treat the result as arithmetic, not as a statement of what you are owed. For that, read your contract and the guidance from your labour authority, or ask your payroll department.
What this calculator does not do
- It does not work out hours from clock-in and clock-out times. The timesheet calculator on this site does that; bring the weekly totals back here.
- It does not apply a daily or weekly threshold for you. You split the hours into regular, overtime and double time yourself.
- It uses one hourly rate. If you worked at two rates in the same week, or earned a bonus or commission that changes your regular rate of pay, the legally correct overtime rate can be a weighted figure this tool does not compute.
- It does not convert a salary to an hourly rate. Use the hourly to salary converter first, then enter the hourly figure.
- All results are gross. Tax, pension, insurance and other deductions are not taken off.
- The multiplier comes from a fixed list: 1.25x, 1.5x, 1.75x, 2x, 2.5x and 3x. Double-time hours are always paid at exactly 2x.
How to get your result
- 1
Enter your Hourly rate. Use the plain number without a currency symbol; the results are in the same currency.
- 2
Enter Regular hours: the hours paid at your normal rate for the week or pay period.
- 3
Enter Overtime hours: the hours paid at the higher rate.
- 4
Choose the Overtime multiplier. Leave it on 1.5x (time and a half) or pick 2x (double time) or another rate from the list.
- 5
If some hours are paid at twice your rate on top of that, enter them in Double-time hours (optional).
- 6
Read Total pay, Regular pay, Overtime pay, Overtime rate and Effective hourly rate, then copy the Summary if you want to keep it.
