Updated February 2026 · 10 min read
Whether you're an hourly worker checking your paycheck, a freelancer invoicing a client, or a small business owner running payroll, knowing how to calculate overtime correctly is essential. This guide breaks down everything you need to know — from the basic formula to complex scenarios involving daily overtime and double time.

1. What Is Overtime Pay?
Overtime pay is the additional compensation an employer must pay an employee for working beyond the standard number of hours. In the United States, the Fair Labor Standards Act (FLSA) is the federal law that governs overtime. It requires employers to pay eligible employees at least 1.5 times their regular hourly rate ("time and a half") for every hour worked over 40 in a single workweek.
The key concepts are:
- Regular rate — Your standard hourly pay (1.0x). This is the rate for the first 40 hours in a week (under federal law).
- Overtime rate — Typically 1.5x your regular rate. Applied to hours exceeding the threshold.
- Workweek — Any fixed, recurring 168-hour period (7 consecutive 24-hour days). Your employer defines when the workweek starts.
Important: Overtime is calculated on a per-workweek basis under federal law. You cannot average hours across multiple weeks unless covered by a specific exception (such as the 8/80 rule in healthcare).
2. The Basic Overtime Formula
The overtime pay calculation has three steps:
1. Regular Pay = Regular Hours × Hourly Rate
2. Overtime Pay = OT Hours × (Hourly Rate × 1.5)
3. Total Gross Pay = Regular Pay + Overtime Pay
Example: If you earn $20/hour and work 45 hours in a week:
| Component | Calculation | Amount |
|---|---|---|
| Regular Pay | 40h × $20.00 | $800.00 |
| Overtime Pay | 5h × $30.00 (1.5×) | $150.00 |
| Total Gross Pay | $950.00 |
Without overtime, you would have earned 45 × $20 = $900. The 5 overtime hours at 1.5x add an extra $50 in premium pay.
3. Weekly vs. Daily Overtime
Most people only know about weekly overtime, but several states also enforce daily overtime. The difference matters a lot:
📅 Weekly Overtime
Used by most of the US (Federal FLSA), Ontario, Quebec, and many other jurisdictions.
Rule: OT applies after 40 hours in a workweek (some states use 44 or 48).
Example: You work 12h on Monday but only 30h total. No overtime owed.
⏰ Daily Overtime
Used by California, Alaska, Nevada, Colorado, and British Columbia.
Rule: OT applies after 8 hours in a single day (12h in Colorado).
Example: You work 10h on Monday, only 30h total. 2 hours of OT owed.
Some jurisdictions, like California, apply both weekly and daily overtime simultaneously. If you work 9 hours on Monday through Friday (45 hours total), you'd get 5 hours of daily OT (1 hour per day over the 8-hour threshold) plus any remaining weekly OT beyond 40 hours. Our free calculator handles these complex overlapping rules automatically.
4. Understanding Double Time
Double time means your employer pays you twice your regular hourly rate (2.0x). It's less common than time-and-a-half and only mandated in certain jurisdictions:
- California: Double time after 12 hours in a single day, or after 8 hours on the 7th consecutive workday in a workweek.
- British Columbia: Double time after 12 hours in a single day.
- Union contracts: Many collective bargaining agreements include double time for holidays, weekends, or extreme hours.
Example (California): You work a 14-hour day at $25/hour:
| Hours | Rate | Pay |
|---|---|---|
| First 8 hours (regular) | $25.00 (1.0x) | $200.00 |
| Hours 9–12 (overtime) | $37.50 (1.5x) | $150.00 |
| Hours 13–14 (double time) | $50.00 (2.0x) | $100.00 |
| Total | 14 hours | $450.00 |
Without overtime or double time, 14 × $25 = $350. With California's rules, you earn $100 more — a 28.6% premium.
5. How Breaks Affect Overtime
Breaks directly impact your overtime calculation because unpaid breaks reduce your total hours worked. There are two types:
Paid Breaks (Rest Breaks)
Short breaks (typically 5–20 minutes) are usually paid and count toward hours worked. Federal law considers breaks under 20 minutes as compensable time. These do count toward overtime.
Unpaid Breaks (Meal Breaks)
Longer breaks (typically 30–60 minutes for lunch) are usually unpaid and do not count toward hours worked. However, if you are not completely relieved of duties during a meal break, it may be considered paid time. These should be deducted from your total hours before calculating overtime.
Example: You clock in at 8:00 AM, take a 30-minute unpaid lunch, and clock out at 5:30 PM. Your gross time is 9.5 hours, but after deducting the 30-minute break, your net hours worked = 9 hours. In California, that means 1 hour of daily overtime.
6. Step-by-Step: Calculate Your Overtime Pay
Find your regular hourly rate
Check your pay stub or employment agreement. If you're salaried, divide your annual salary by 2,080 (52 weeks × 40 hours). Example: $52,000 ÷ 2,080 = $25.00/hour.
Record start and end times for each day
Be precise — don't round. Even 5 minutes per day adds up to over 21 hours a year. Record in whatever format you prefer (12h or 24h).
Subtract unpaid breaks
Deduct any unpaid meal breaks from each day's total. Paid rest breaks (under 20 minutes) should be included in your hours.
Identify your overtime rules
Check whether your state uses weekly OT only (most states), daily OT (California, Alaska, Nevada), or both. Make sure to use the correct thresholds.
Separate regular, OT, and double time hours
Apply the thresholds to categorize your hours into regular (1.0x), overtime (1.5x), and double time (2.0x) buckets.
Calculate total pay
Multiply each category by its rate and sum them up. This is your total gross (pre-tax) pay for the week.
7. Real-World Examples
Example A: Standard Federal Overtime
Worker in Texas, $18/hour, no daily OT rule.
| Day | Mon | Tue | Wed | Thu | Fri | Sat | Total |
|---|---|---|---|---|---|---|---|
| Hours | 9 | 9 | 9 | 9 | 9 | 0 | 45 |
Regular: 40h × $18 = $720 | OT: 5h × $27 = $135 | Total: $855
Example B: California Daily + Weekly OT
Worker in California, $22/hour. Daily OT > 8h, double time > 12h.
| Day | Mon | Tue | Wed | Thu | Fri | Total |
|---|---|---|---|---|---|---|
| Hours | 10 | 10 | 8 | 8 | 6 | 42 |
Daily OT: Mon 2h + Tue 2h = 4 hours at 1.5x
Remaining weekly hours: 42 − 4 (daily OT) = 38 regular → no additional weekly OT
Regular: 38h × $22 = $836 | Daily OT: 4h × $33 = $132 | Total: $968
8. Who Is Exempt from Overtime?
Not all workers are entitled to overtime. Under the FLSA, the following employees may be classified as "exempt" (not eligible for OT):
- Executive employees — Manage a department or subdivision, supervise 2+ employees, have authority to hire/fire.
- Administrative employees — Perform office/non-manual work related to management or business operations, exercise independent judgment.
- Professional employees — Work requires advanced knowledge in a field of science or learning (doctors, lawyers, engineers, teachers).
- Computer professionals — Systems analysts, programmers, software engineers earning at least $27.63/hour (or $684/week salary).
- Outside sales employees — Primary duty is making sales outside the employer's place of business.
Salary threshold (2025–2026): To be exempt, an employee generally must earn at least $58,656/year ($1,128/week) on a salary basis. If you earn less than this, you may be eligible for overtime regardless of your job duties. This threshold was updated in 2024.
9. Common Mistakes to Avoid
❌ Rounding your hours too aggressively
Rounding 8:53 AM to 9:00 AM might seem harmless, but losing 7 minutes daily adds up to over 29 hours (nearly a full workweek) per year.
❌ Averaging hours across weeks
Working 50 hours one week and 30 the next doesn't average to 40. You're owed 10 hours of OT for the first week.
❌ Forgetting about daily overtime
If you work in California or another state with daily OT, you can earn overtime even if your weekly total is under 40 hours.
❌ Not deducting unpaid breaks
Including a 30-minute lunch in your hours inflates your total by 2.5 hours per week. Always deduct unpaid breaks.
❌ Assuming all salaried workers are exempt
Many salaried workers earning under the salary threshold are still entitled to overtime. Check the exemption criteria above.
