Struggling with overtime calculations? Many small business owners underpay or overpay employees due to time and a half confusion, risking fines up to $1,000 per violation under FLSA. Get it right with this guide.
What Is Time and a Half?
Time and a half means paying non-exempt employees 1.5 times their regular hourly rate for hours worked over 40 in a workweek. This stems from the Fair Labor Standards Act (FLSA), covering most U.S. hourly workers.
Contractors who bill clients for overtime can add it as its own hourly line, at the higher rate, in PineBill's free invoice generator.
Federal law mandates this for overtime, but some states like California require daily overtime after 8 hours. According to the U.S. Department of Labor, non-compliance affects millions of workers annually.

Who Qualifies for Time and a Half?
Only non-exempt employees qualify. Exempt workers (executive, administrative, professional) earning above $35,568 annually ($684/week as of 2025, post-rule vacatur) don't get overtime.
Hourly employees are typically non-exempt. Salaried non-exempt get overtime based on their regular rate equivalent.
Small businesses: Classify correctly to avoid DOL audits. Misclassification is the top overtime violation.
Federal and State Overtime Laws
FLSA requires time and a half after 40 hours/week. Key 2025 notes:
- Salary threshold reverted to 2019 levels after 2024 rule blocked.
- States like CA, NY require daily OT (after 8-10 hours/day).
- No federal daily OT, but 7 states mandate it.
| Requirement | Federal (FLSA) | Example States (Stricter) |
|---|---|---|
| OT Trigger | >40 hrs/week | CA: >8 hrs/day or >40/week |
| Rate | 1.5x regular | Same, or 2x on 7th day (CA) |
| Exempt Salary | $35,568/year | Higher in some states |
Always check state laws via DOL website.
How to Calculate Time and a Half: Step-by-Step
Follow these steps for accurate payroll.
Determine Regular Hourly Rate
Include base wage plus non-discretionary bonuses/shift differentials divided by total hours.
Example: $20/hr base + $200 weekly bonus / 40 hrs = $25 regular rate.
Add to Regular Pay
Total pay = (regular rate x 40) + OT pay.
Real-World Calculation Examples
| Scenario | Regular Rate | Reg Hrs | OT Hrs | OT Rate | Total Pay |
|---|---|---|---|---|---|
| Basic Weekly | $15 | 40 | 5 | $22.50 | $697.50 |
| With Bonus | $20 (+$100 bonus/40hrs = $22.50 reg) | 40 | 10 | $33.75 | $1,012.50 |
| Salaried Non-Exempt ($800/wk /40 = $20/hr) | $20 | 35 | 10 | $30 | $950 |
BLS data shows average 3.6 OT hours/week across industries.

Common Mistakes to Avoid
- Wrong regular rate: Exclude bonuses? Fines follow.
- Averaging hours: Calculate per workweek, not pay period.
- Off-clock work: Training, travel counts.
- Exempt misclassification: Review duties test.
- State ignorance: CA daily OT trips up many.
DOL recovered $238M in back wages last year.
Key Takeaways
- Time and a half = 1.5x regular rate after 40 hrs/week (FLSA).
- Include all pay in regular rate.
- Check state laws for daily OT.
- Use tools like PineBill for compliance.
- Audit classifications annually.
