# Overtime Calculator

> Enter the hourly rate, the regular hours and the overtime hours. Change the overtime multiplier if yours is not 1.5, and add double-time hours if you have them. You get regular pay, overtime pay, total gross pay and the effective hourly rate. $20 an hour for 40 regular and 8 overtime hours is $1,040.00.

## How it works

Regular pay = rate × regular hours. Overtime pay = rate × the overtime multiplier × overtime hours, where time and a half is a multiplier of 1.5. Double-time pay = rate × the double-time multiplier × double-time hours. Gross pay = regular + overtime + double time. Effective hourly rate = gross pay ÷ all hours worked. If you only know the total hours, the page can split them: hours above the weekly limit (40 is the usual US limit) are overtime. This is gross pay before tax.

**Overtime pay for 8 overtime hours at different rates (time and a half)**

| Hourly rate | Overtime rate | 8 overtime hours |
| --- | --- | --- |
| $15.00 | $22.50 | $180.00 |
| $20.00 | $30.00 | $240.00 |
| $25.00 | $37.50 | $300.00 |
| $30.00 | $45.00 | $360.00 |
| $40.00 | $60.00 | $480.00 |

**Overtime multipliers you may meet**

| Name | Multiplier | Typical use |
| --- | --- | --- |
| Time and a half | 1.5 | Hours over 40 in a week under US federal rules, and many contracts |
| Double time | 2 | Some states for very long days, holidays, and many union contracts |
| Straight time | 1 | Hours that are not overtime |

## Worked example: 48 hours in a week at $20 an hour

1. Regular pay: 40 hours × $20 = $800.00.
2. Overtime pay: 8 hours × $20 × 1.5 = $240.00.
3. Gross pay: $1,040.00 for 48 hours, an effective rate of $21.67 an hour.
4. If 2 of those hours were double time: the gross becomes $1,120.00, an effective $22.40 an hour.

## FAQ

### How do I calculate overtime pay?
Multiply the hourly rate by the overtime multiplier, usually 1.5, and by the overtime hours. Add that to the regular pay for the regular hours.

### How many hours before overtime starts?
Under US federal rules, for non-exempt workers it is after 40 hours in a workweek. Some states and contracts also count daily hours, so check your own rules.

### What is time and a half?
An hourly rate of one and a half times the regular rate. For a $20 worker that is $30 an hour.

### What is double time?
Two times the regular rate. It applies in some states after very long days and in many union contracts, so it is a separate box here.

### Why is the effective hourly rate higher than the base rate?
Because the overtime hours pay more, the average over all hours rises. It shows what an hour really costs.

### Is this the amount that arrives in the bank?
No. It is gross pay before tax and other deductions.
