Overtime Calculator
Enter an hourly rate, the hours worked in a week, the number of hours after which overtime starts and an overtime multiplier to see regular pay, overtime pay and gross pay for the week.
Rate and hours for one week
The rate is in dollars and cents. The defaults, overtime after 40 hours at 1.5 times the rate, follow the US federal rule quoted below. Change the threshold and multiplier to the rule that applies to you.
The rate for an hour that isn't overtime.
All hours worked in one workweek, including any overtime. Use decimals for part hours: 30 minutes is 0.5.
Hours above this number are paid at the overtime rate.
1.5 is time and a half; 2 is double time.
Gross pay for the week
$1,372.00
40 regular hours and 6 overtime hours.
Blended rate: $29.83 per hour over 46 hours.
Working
- Regular pay (40 hours × rate)
- $1,120.00
- Overtime rate (rate × 1.5)
- $42.00 per hour
- Overtime pay (6 hours × overtime rate)
- $252.00
- Gross pay (regular + overtime)
- $1,372.00
Regular pay and overtime pay are each rounded to the nearest cent (half a cent rounds up), and gross pay is their sum. The overtime rate is shown without rounding.
How overtime pay is worked out
- Regular hours = hours worked, up to the threshold.
- Overtime hours = hours worked above the threshold (0 if there are none).
- Regular pay = regular hours × hourly rate.
- Overtime rate = hourly rate × multiplier.
- Overtime pay = overtime hours × overtime rate.
- Gross pay = regular pay + overtime pay.
- Blended rate = gross pay ÷ hours worked.
Regular pay, overtime pay and the blended rate are each rounded to the nearest cent, with half a cent rounding up, and gross pay is the sum of the two rounded amounts. The overtime rate is shown without rounding, so a rate such as $37.875 an hour isn't cut to $37.88 before it's multiplied.
Example, using the calculator's starting values: $28.00 an hour for 46 hours, with overtime after 40 hours at 1.5 times the rate. Regular pay is 40 × $28.00 = $1,120.00. The overtime rate is $28.00 × 1.5 = $42.00, so overtime pay is 6 × $42.00 = $252.00. Gross pay is $1,372.00, and the blended rate is $1,372.00 ÷ 46 = $29.83 an hour.
The US federal rule (FLSA)
The defaults follow the US federal overtime rule. The US Department of Labor's Overtime Pay page (opened October 29, 2026) says:
“The federal overtime provisions are contained in the Fair Labor Standards Act (FLSA). Unless exempt, employees covered by the Act must receive overtime pay for hours worked over 40 in a workweek at a rate not less than time and one-half their regular rates of pay.”
The same page says: “Averaging of hours over two or more weeks is not permitted.” That's why the calculator works on one week. The Department's Fact Sheet #23: Overtime Pay Requirements of the FLSA (revised October 2019, opened October 29, 2026) explains what the regular rate includes and how it's worked out for pay on a salary, piece-rate or commission basis. This rule applies in the US only. State laws, employment contracts and the laws of other countries can set a different threshold or multiplier, so check the rules where you work and enter them above. The calculator doesn't decide whether someone is owed overtime.
Overtime in your labor costs
Overtime raises what an hour of labor costs you, as the blended rate shows. If client work needs overtime, allow for that cost in your quote or project rate. To work out what an hour of your own time needs to earn, use the freelance hourly rate calculator. When labor is part of what each unit you make costs, use the cost per unit calculator. If you're about to take on staff, the guide how to hire your first employee covers worker classification, budgeting the cost of a hire, onboarding and payroll setup.
