Calculate your overtime pay, time and a half, double-time, and total weekly gross pay from an hourly rate or salary, including the regular and effective rate.
Overtime Pay Formula
The calculator runs in several modes, but each one is built on the same set of pay formulas.
Regular Pay = R * H_reg
Overtime Pay = R * 1.5 * H_ot
Double-Time Pay = R * 2 * H_dt
Gross Pay = Regular Pay + Overtime Pay + Double-Time Pay + Other Pay
The variables are:
- R = your regular hourly rate of pay, in dollars
- H_reg = regular hours, paid at the base rate
- H_ot = overtime hours, paid at 1.5 times the regular rate (time and a half)
- H_dt = double-time hours, paid at 2 times the regular rate
- Other Pay = any bonus or extra pay added to the period
The 1.5 and 2 multipliers are the defaults you can change under the options. The overtime multiplier sets how much each overtime hour pays above the regular rate, and the double-time multiplier does the same for double-time hours. The weekly threshold, set to 40 hours by default, is the point at which extra hours start counting as overtime.
If you start from an annual salary instead of an hourly wage, the calculator first converts the salary into a regular rate:
R = Annual Salary / Paid Weeks / Hours per Week
The auto-split mode handles the case where you only know the total hours worked. It places every hour up to the weekly threshold into regular hours and sends the remainder to overtime, then applies the formulas above. The two target modes work in reverse: one solves for the overtime hours needed to reach a target gross pay, and the other solves for the hourly rate needed to reach a target gross pay. The effective hourly rate shown with each result is the gross pay spread across every hour worked:
Effective Rate = Gross Pay / Total Hours
Overtime Multipliers and Pay Rates
Overtime pay is set by a multiplier applied to your regular rate. The first table shows the standard multipliers and what each one pays on a $20 hourly rate. The second table converts common hourly wages into their time-and-a-half overtime rate.
| Pay type | Multiplier | Rate on $20/hr |
|---|---|---|
| Regular | 1.0x | $20.00 |
| Time and a half (overtime) | 1.5x | $30.00 |
| Double time | 2.0x | $40.00 |
| Regular rate | Overtime rate (1.5x) |
|---|---|
| $12.00 | $18.00 |
| $15.00 | $22.50 |
| $20.00 | $30.00 |
| $25.00 | $37.50 |
| $30.00 | $45.00 |
| $40.00 | $60.00 |
Example Problems
Example 1. You earn $20 per hour and work 40 regular hours plus 6 overtime hours in one week. Your regular pay is 40 * $20 = $800. Your overtime pay is 6 * $20 * 1.5 = $180. Your gross pay is $800 + $180 = $980.
Example 2. You earn $25 per hour and work 48 total hours with the auto-split mode and a 40-hour threshold. The first 40 hours are regular: 40 * $25 = $1,000. The remaining 8 hours are overtime: 8 * $25 * 1.5 = $300. Your gross pay is $1,000 + $300 = $1,300, and your effective rate is $1,300 / 48 = $27.08 per hour.
FAQ
When does overtime start? Under the federal Fair Labor Standards Act, non-exempt employees earn overtime for hours worked beyond 40 in a single workweek. A workweek is any fixed, recurring period of 168 hours. Some states add their own rules, such as daily overtime after 8 hours, so check your state if it applies to you.
What is the regular rate of pay? The regular rate is your average hourly earnings for the week, found by dividing your total pay for the week by the total hours you actually worked. For a simple hourly job it equals your stated wage, but bonuses and other earnings can raise it, which in turn raises the overtime rate.
Is overtime taxed at a higher rate? No. Overtime is taxed as ordinary income just like the rest of your pay. A paycheck with overtime can have more withheld because the larger gross amount can push that single check into a higher withholding bracket, but the extra money is not taxed under a separate overtime rate.
