Sample Calculations: Understanding How It Works
Let's walk through two real-world examples to show you exactly how overtime is calculated under each rule. Both examples use the same work schedule and a $20/hour rate to make direct comparison easy.
Note: These examples use $20/hour for simple, clear math ($30 for 1.5×, $40 for 2×). Both examples use identical hours worked so you can see exactly how the calculation rules differ. Enter your actual hourly rate in the calculator above to get your personalized results.
Example 1: Weekly Overtime (40-Hour Rule)
Scenario: You work for a company that follows federal FLSA guidelines. You earn $20/hour and work the following schedule:
| Day | Hours | Regular | OT (1.5×) | Daily Pay |
|---|---|---|---|---|
| Monday | 8.0 | 8.0 | 0.0 | $160.00 |
| Tuesday | 8.0 | 8.0 | 0.0 | $160.00 |
| Wednesday | 8.0 | 8.0 | 0.0 | $160.00 |
| Thursday | 12.0 | 12.0 | 0.0 | $240.00 |
| Friday | 10.0 | 4.0 | 6.0 | $260.00 |
| Saturday | 0.0 | 0.0 | 0.0 | $0.00 |
| Sunday | 0.0 | 0.0 | 0.0 | $0.00 |
| Total | 46.0 | 40.0 | 6.0 | $980.00 |
How This Works:
- Monday–Thursday: You work 36 total hours (running total: 8 + 8 + 8 + 12 = 36). Since you haven't reached 40 hours yet, all hours are paid at your regular rate of $20/hour.
- Friday (The Key Day): You work 10 hours. Your running total for the week becomes 46 hours (36 + 10). The first 4 hours get you to the 40-hour threshold (all regular pay). The remaining 6 hours are overtime, paid at 1.5× your rate ($30/hour).
- Calculation Breakdown:
- Regular Pay: 40 hours × $20 = $800.00
- Overtime Pay: 6 hours × $30 (1.5× rate) = $180.00
- Total Weekly Pay: $980.00
Important: Notice that even though you worked 12 hours on Thursday, those are all regular hours because you hadn't exceeded 40 hours for the week yet. Overtime only kicks in after you cross the 40-hour weekly threshold.
Example 2: Daily Overtime (8/12-Hour Rule)
Scenario: You work in California where daily overtime rules apply. You earn $20/hour and work the same schedule as Example 1:
| Day | Hours | Regular | OT (1.5×) | OT (2×) | Daily Pay |
|---|---|---|---|---|---|
| Monday | 8.0 | 8.0 | 0.0 | 0.0 | $160.00 |
| Tuesday | 8.0 | 8.0 | 0.0 | 0.0 | $160.00 |
| Wednesday | 8.0 | 8.0 | 0.0 | 0.0 | $160.00 |
| Thursday | 12.0 | 8.0 | 4.0 | 0.0 | $280.00 |
| Friday | 10.0 | 8.0 | 2.0 | 0.0 | $220.00 |
| Saturday | 0.0 | 0.0 | 0.0 | 0.0 | $0.00 |
| Sunday | 0.0 | 0.0 | 0.0 | 0.0 | $0.00 |
| Total | 46.0 | 40.0 | 6.0 | 0.0 | $980.00 |
How This Works:
- Monday–Wednesday: You work exactly 8 hours each day. All hours are regular pay at $20/hour.
- Thursday (12-Hour Day):
- First 8 hours = Regular pay ($20/hour) = $160
- Next 4 hours (hours 9-12) = OT at 1.5× ($30/hour) = $120
- Hours beyond 12 = OT at 2× ($40/hour) = $0 (you didn't exceed 12 hours)
- Thursday Total: $280
- Friday (10-Hour Day):
- First 8 hours = Regular pay ($20/hour) = $160
- Next 2 hours (hours 9-10) = OT at 1.5× ($30/hour) = $60
- Friday Total: $220
- Total Weekly Pay:
- Regular Pay: 40 hours × $20 = $800.00
- OT Pay (1.5×): 6 hours × $30 = $180.00
- OT Pay (2×): 0 hours × $40 = $0.00
- Total: $980.00
Key Difference: With daily OT rules, overtime is calculated each day based on that day's hours. Any hours over 8 in a single day earn 1.5×, and any hours over 12 in a single day earn 2×. The weekly total doesn't matter—it's all about individual day thresholds.
Comparing the Two Rules
Notice that in this particular example, both methods result in the same total pay ($980) and the same number of overtime hours (6). However, this is not always the case:
When Weekly OT Pays More
If you work consistent 8-hour days and only exceed 40 hours on the last day, weekly OT can result in higher pay since all excess hours count as overtime.
When Daily OT Pays More
If you work long days (10+ hours) but stay under 40 hours per week, daily OT rules ensure you get overtime pay for those long days, while weekly OT wouldn't trigger at all.
Understanding Overtime Rules
Weekly Overtime (Federal FLSA)
Under federal law, hours beyond 40 in a workweek earn 1.5× your regular rate. This is the most common overtime calculation used across the United States.
Daily Overtime (State Laws)
Some states (like California, Alaska, and Nevada) require daily overtime: 1.5× after 8 hours per day and 2× after 12 hours per day, regardless of weekly totals.
Double-Time Pay
In daily overtime jurisdictions, hours worked beyond 12 in a single day typically earn double your regular rate (2×). This provides extra compensation for very long work days.
Employer Policies May Vary
Always verify your specific overtime rules with your employer. Some organizations offer more generous overtime policies than legally required, such as overtime after 37.5 hours or daily OT in non-required states.
