How to Calculate Overtime Pay
Calculating overtime pay is straightforward once you know the formula. Here is how it works step by step:
- Determine your regular hourly rate (your base pay per hour).
- Find your overtime hours, the number of hours worked beyond your overtime threshold (usually 40 hours per week under federal law).
- Multiply your overtime hours by your overtime rate. For time and a half, that is your hourly rate × 1.5.
The overtime pay formula:
Overtime Pay = (Hours Over Threshold) × (Hourly Rate × Overtime Multiplier)
For example, if you earn $25 per hour and work 48 hours in a week with a 40-hour threshold at 1.5x:
- Regular pay: 40 hours × $25 = $1,000
- Overtime hours: 48 − 40 = 8 hours
- Overtime rate: $25 × 1.5 = $37.50/hr
- Overtime pay: 8 × $37.50 = $300
- Total weekly pay: $1,000 + $300 = $1,300
Use the overtime calculator above to run this calculation instantly for any hourly rate and hours worked. This overtime hours calculator handles all the math, just enter your numbers and see the breakdown.
What Is Time and a Half?
Time and a half means you earn 1.5 times your regular hourly rate for each overtime hour worked. It is the most common overtime pay rate in the United States, required by the Fair Labor Standards Act (FLSA) for most non-exempt employees. Our time and a half calculator above makes it easy to see exactly what you earn at 1.5x.
To calculate your time and a half rate, simply multiply your hourly rate by 1.5. You can also use our overtime pay calculator to see the full breakdown:
- $15/hr → $22.50/hr at time and a half
- $20/hr → $30.00/hr at time and a half
- $25/hr → $37.50/hr at time and a half
- $30/hr → $45.00/hr at time and a half
Time and a half applies to all hours worked beyond 40 in a single workweek for non-exempt employees. Some states and union contracts may have additional rules, for example, California requires time and a half after 8 hours in a single day. Use the overtime calculator above to calculate overtime pay for your specific situation.
Overtime Pay by Hourly Rate
Here is a quick reference showing what you earn per overtime hour at common hourly rates. This overtime pay calculator table covers both time and a half (1.5x) and double time (2x) rates, plus what 5 and 10 overtime hours per week add to your paycheck.
| Hourly Rate | Time and a Half | Double Time | 5 OT hrs/wk | 10 OT hrs/wk |
|---|---|---|---|---|
| $15/hr | $22.50/hr | $30.00/hr | $112.50/wk | $225.00/wk |
| $20/hr | $30.00/hr | $40.00/hr | $150.00/wk | $300.00/wk |
| $25/hr | $37.50/hr | $50.00/hr | $187.50/wk | $375.00/wk |
| $30/hr | $45.00/hr | $60.00/hr | $225.00/wk | $450.00/wk |
| $35/hr | $52.50/hr | $70.00/hr | $262.50/wk | $525.00/wk |
| $40/hr | $60.00/hr | $80.00/hr | $300.00/wk | $600.00/wk |
| $45/hr | $67.50/hr | $90.00/hr | $337.50/wk | $675.00/wk |
| $50/hr | $75.00/hr | $100.00/hr | $375.00/wk | $750.00/wk |
These figures assume a standard 40-hour overtime threshold with time and a half (1.5x). Your actual overtime pay depends on your employer’s policy, state law, and any union agreements. Use the overtime calculator above to get your exact numbers with any hourly rate and overtime hours.
FLSA Overtime Rules
The Fair Labor Standards Act (FLSA) is the federal law that governs overtime pay in the United States. Understanding these rules helps you calculate overtime pay accurately. Here are the key rules every worker should know:
The 40-Hour Threshold
Under the FLSA, non-exempt employees must receive overtime pay at a rate of at least 1.5 times their regular rate for all hours worked over 40 in a workweek. This is a weekly calculation, employers cannot average hours across multiple weeks.
Exempt vs Non-Exempt Employees
Not everyone qualifies for overtime. The FLSA defines two categories:
- Non-exempt employees are entitled to overtime pay. Most hourly workers fall into this category.
- Exempt employees are not entitled to overtime. To be exempt, an employee must generally earn at least $35,568 per year ($684 per week) on a salary basis AND perform specific job duties (executive, administrative, professional, computer, or outside sales).
Being paid a salary does not automatically make you exempt. Both the salary threshold and the duties test must be met. If you are unsure about your status, check with the Department of Labor’s overtime pay requirements. If you are non-exempt, use our overtime pay calculator to see what you should be earning.
Common Misconceptions
- Overtime is not optional for employers, if a non-exempt employee works over 40 hours, the employer must pay overtime regardless of whether the overtime was authorized.
- Comp time (time off instead of overtime pay) is generally not allowed for private-sector employees under the FLSA.
- The FLSA does not require overtime for working weekends, holidays, or night shifts, only for hours exceeding 40 per week (though state laws may differ).
Overtime Laws by State
While the FLSA sets the federal baseline, several states have their own overtime laws that provide additional protections. Here are the most notable:
| State | Weekly Threshold | Daily Threshold | Special Rules |
|---|---|---|---|
| California | 40 hrs | 8 hrs | Double time after 12 hrs/day; time and a half on 7th consecutive day; double time after 8 hrs on 7th day |
| Alaska | 40 hrs | 8 hrs | Daily overtime after 8 hours for most employees |
| Nevada | 40 hrs | 8 hrs | Daily overtime if hourly rate is less than 1.5x minimum wage |
| Colorado | 40 hrs | 12 hrs | Daily overtime after 12 hours; also after 12 consecutive hours |
| Oregon | 40 hrs | None | Manufacturing: daily OT after 10 hrs |
| Washington | 40 hrs | None | Agricultural workers have specific overtime rules |
| New York | 40 hrs | None | Residential employees: OT after 44 hrs |
| Minnesota | 48 hrs | None | Higher weekly threshold than federal standard |
If your state has a daily overtime threshold (like California’s 8-hour rule), you may earn overtime even if your weekly total is under 40 hours. Always check your state’s specific rules, the stricter law (federal or state) applies. Our overtime hours calculator uses the weekly threshold by default, but you can adjust it to match your state’s daily rules.
Overtime for Shift Workers
If you work a rotating shift schedule, overtime is often built into your pattern. Many 12-hour and 24-hour shift patterns average more than 40 hours per week, which means automatic overtime every pay period. This overtime calculator supports all 12 major shift patterns so you can see your exact overtime hours and pay.
Here is how common shift patterns stack up for overtime:
| Shift Pattern | Avg Hours/Week | Weekly OT Hours | OT Pay at $25/hr (1.5x) |
|---|---|---|---|
| 2-2-3 (Panama) | 42 | 2 | $75.00/wk |
| DuPont | 42 | 2 | $75.00/wk |
| Pitman | 42 | 2 | $75.00/wk |
| 4-on-4-off | 42 | 2 | $75.00/wk |
| 4-on-2-off | 46.7 | 6.7 | $251.25/wk |
| Continental | 42 | 2 | $75.00/wk |
| Kelly | 56 | 16 | $600.00/wk |
| 24/48 | 56 | 16 | $600.00/wk |
| 48/96 | 56 | 16 | $600.00/wk |
| DDNNOO | 56 | 16 | $600.00/wk |
Firefighters on a Kelly or 24/48 schedule earn significant overtime, 16 overtime hours per week at time and a half adds $600 weekly (at $25/hr). That is over $31,000 in overtime pay per year. Use the overtime pay calculator above to calculate overtime pay for your specific pattern and hourly rate.

Weekly vs Biweekly Overtime
A common question: does overtime reset every week or every pay period? Under the FLSA, overtime must be calculated on a weekly basis, not biweekly, semimonthly, or monthly. This is important when you use an overtime calculator to verify your paycheck.
This means your employer cannot average your hours across a two-week pay period to avoid paying overtime. Here is an example:
- Week 1: You work 50 hours
- Week 2: You work 30 hours
- Biweekly total: 80 hours (40/week average)
Even though the biweekly average is 40 hours, you are owed 10 hours of overtime for Week 1. Your employer cannot say “it averages out.” Each week stands on its own for overtime calculation purposes.
The pay period selector in our overtime calculator affects only the earnings projections (how your pay scales to biweekly, monthly, and yearly totals), the overtime calculation itself is always based on a single week, just as the FLSA requires.
Double Time Pay
Double time means earning 2 times your regular hourly rate. If you make $25/hr, double time is $50/hr. While double time is not required by federal law, our double time calculator makes it easy to see your earnings at 2x. It applies in several situations:
- California: Double time is required for hours worked beyond 12 in a single day, and for hours beyond 8 on the 7th consecutive workday.
- Union contracts: Many collective bargaining agreements include double time for holidays, weekends, or excessive overtime hours.
- Employer policy: Some companies voluntarily offer double time for holiday shifts or emergency call-ins.
To calculate double time pay, select “2x (Double Time)” in the overtime multiplier dropdown of the overtime calculator above. You can also enter a custom multiplier for any rate between 1x and 5x.
For workers in California or under union contracts, double time can significantly increase your earnings. At $30/hr with 4 hours of double time per week, that is an extra $240 weekly, over $12,000 per year. Use the overtime pay calculator to see your exact double time earnings.
