What Is Overtime Pay?
Overtime pay is additional pay earned when you work beyond your standard work hours. In many workplaces, overtime begins after a set weekly threshold, such as 40 hours in a workweek. Some workplaces may also use daily overtime, holiday overtime, or special contract-based overtime rules.
The most common overtime rate is time and a half, which means overtime hours are paid at 1.5 times your regular hourly rate.
Important: Overtime rules can vary by country, state, province, employer, contract, and worker classification. Use this guide for general calculation help, and check your local labor rules or employment agreement for exact requirements.
Basic Overtime Pay Formula
The standard overtime formula is:
For time and a half, calculate your overtime rate like this:
So the complete time-and-a-half formula is:
How to Calculate Overtime Pay Step by Step
1. Find Your Regular Hourly Rate
Start with your normal hourly pay rate. For example, if you earn $20 per hour, that is your regular hourly rate.
2. Find Your Total Hours Worked
Add all eligible work hours for the pay period or workweek. If you are unsure of your total hours, use the Work Hours Calculator or Timesheet Calculator first.
3. Separate Regular Hours and Overtime Hours
If your overtime threshold is 40 hours per week and you worked 46 hours, then:
- Total hours worked: 46
- Regular hours: 40
- Overtime hours: 6
4. Calculate Your Overtime Rate
For time and a half, multiply your regular hourly rate by 1.5.
$20 × 1.5 = $30 per overtime hour
5. Multiply Overtime Hours by the Overtime Rate
Now multiply overtime hours by the overtime rate.
6 overtime hours × $30 = $180 overtime pay
6. Add Regular Pay and Overtime Pay
To estimate total gross pay, add your regular earnings and overtime earnings.
Regular pay: 40 × $20 = $800
Overtime pay: 6 × $30 = $180
Total gross pay: $980
Example: Overtime Pay Calculation
- Hourly rate: $18
- Total weekly hours: 45
- Regular hours: 40
- Overtime hours: 5
- Overtime multiplier: 1.5
Step 1: Calculate overtime rate:
$18 × 1.5 = $27 per overtime hour
Step 2: Calculate overtime pay:
5 × $27 = $135 overtime pay
Step 3: Calculate regular pay:
40 × $18 = $720 regular pay
Step 4: Add both together:
$720 + $135 = $855 total gross pay
What Does Time and a Half Mean?
Time and a half means you earn 150% of your regular hourly rate for overtime hours. In simple terms, your overtime rate is your normal hourly rate plus half of that rate again.
| Regular Hourly Rate | Time-and-a-Half Rate |
|---|---|
| $15/hour | $22.50/hour |
| $18/hour | $27.00/hour |
| $20/hour | $30.00/hour |
| $25/hour | $37.50/hour |
| $30/hour | $45.00/hour |
How to Calculate Double Time
Double time means you earn twice your regular hourly rate. Some employers use double time for holidays, certain overtime hours, emergency shifts, or long workdays.
- Regular hourly rate: $22
- Double-time rate: $22 × 2 = $44
- Double-time hours: 3
3 × $44 = $132 double-time pay
How to Calculate Weekly Overtime Hours
To calculate weekly overtime hours, add all hours worked during the workweek, then subtract the regular-hours threshold.
Tuesday: 8 hours
Wednesday: 10 hours
Thursday: 9 hours
Friday: 8 hours
Total weekly hours = 44 hours
Regular hours limit = 40 hours
Overtime hours = 4 hours
If you need to calculate weekly totals first, use the Timesheet Calculator to total daily shifts, break deductions, and overtime hours.
How to Calculate Overtime Pay From Salary
If you are paid a salary and need to estimate an hourly overtime rate, first convert your salary into an hourly rate. A simple estimate is:
- Annual salary: $52,000
- Weekly hours: 40
$52,000 ÷ 52 = $1,000 per week
$1,000 ÷ 40 = $25 per hour
Time-and-a-half overtime rate:
$25 × 1.5 = $37.50 per overtime hour
If you worked 4 overtime hours:
4 × $37.50 = $150 overtime pay
For salary comparisons, you can also use the Hourly to Salary Calculator or Salary to Hourly Calculator.
Overtime Pay vs Regular Pay
Regular pay is what you earn for standard hours. Overtime pay is what you earn for eligible extra hours after your overtime threshold is reached.
| Pay Type | Formula | Example |
|---|---|---|
| Regular Pay | Regular Hours × Hourly Rate | 40 × $20 = $800 |
| Time-and-a-Half Pay | Overtime Hours × (Hourly Rate × 1.5) | 6 × $30 = $180 |
| Double-Time Pay | Double-Time Hours × (Hourly Rate × 2) | 3 × $40 = $120 |
Common Mistakes When Calculating Overtime Pay
- Using the wrong hourly rate
- Forgetting to separate regular hours from overtime hours
- Not totaling all eligible work hours in the week
- Mixing up time and a half with double time
- Forgetting unpaid break deductions when calculating hours worked
- Using gross pay instead of regular hourly rate for the overtime formula
- Assuming every salaried worker qualifies for overtime

Why Accurate Overtime Calculations Matter
Accurate overtime calculations help employees check their pay, help employers reduce payroll errors, and help managers understand labor costs more clearly. Even a small mistake in overtime rate, break deductions, or total weekly hours can create paycheck errors over time.
For workers, overtime calculations can also help with budgeting and deciding whether extra shifts are worth it. For employers, accurate overtime tracking helps with scheduling, payroll planning, and fair compensation.
