When to use this calculator
- Hourly employees verifying their weekly paycheck before payday
- Freelancers tracking billable hours across a 7-day week
- Managers estimating labor costs for a team member's schedule
- Part-time workers checking whether they've crossed the overtime threshold
- Small business owners calculating gross payroll for weekly pay runs
- Job seekers comparing take-home pay across different hourly offers
Overtime Rules by State — 2026 (Key Variations from Federal 40-hr Rule)
| State | Daily OT Threshold | Weekly OT Threshold | Double-Time Trigger | Governing Authority |
|---|---|---|---|---|
| California | After 8 hrs/day | After 40 hrs/week | After 12 hrs/day or 8 hrs on 7th consecutive day | CA Labor Code §510; IWC Wage Orders |
| Alaska | After 8 hrs/day | After 40 hrs/week | None (state law) | AS 23.10.060 |
| Nevada | After 8 hrs/day (if <$18.00/hr in 2026) | After 40 hrs/week | None (state law) | NRS 608.018 |
| All other states | No daily threshold | After 40 hrs/week | No federal requirement | FLSA 29 U.S.C. §207 |
| Federal (FLSA) | No daily threshold | After 40 hrs/week | No federal requirement | U.S. DOL – WHD |

How it works
What Is Overtime?
Overtime is any work hours beyond 40 in a standard workweek, typically compensated at 1.5× your regular hourly rate. Under the Fair Labor Standards Act (FLSA), this rule applies to non-exempt employees in the United States. Some states go further: California mandates overtime after 8 hours in a single day (daily overtime), not just after 40 weekly hours — a distinction this calculator does not cover.
> Quick example: 45 hours at $20/hour → 40 regular hours ($800) + 5 OT hours at $30/hour ($150) = $950 gross pay.

How It Works
The calculator uses decimal hours (e.g., 9.50 = 9:30 AM) for all inputs. For each day, it subtracts the clock-in time from the clock-out time, then deducts the lunch break:
daily_hours = (clock_out − clock_in) − (lunch_minutes / 60)Negative or zero values — rest days, holidays, or blank entries — are treated as 0 hours. The seven daily totals are summed into a weekly total:
weekly_total = Σ daily_hours (Mon–Sun)---
Regular vs. Overtime Hours
regular_hours = min(weekly_total, 40)
ot_hours = max(weekly_total − 40, 0)The FLSA defines a workweek as any fixed, recurring period of 168 consecutive hours (7 × 24 hours). Employers choose which day starts their workweek — it does not have to be Monday. Hours cannot be averaged across two weeks: 50 hours one week + 30 the next are not equivalent to 40 + 40 for overtime purposes.

Gross Pay Formula
gross_pay = (regular_hours × rate) + (ot_hours × rate × 1.5)Worked example: Mon–Fri, 9 AM to 6 PM with a 30-minute lunch each day → 8.5 h/day × 5 days = 42.5 total hours. At $22/hr:
| Metric | Value |
|---|---|
| Total hours | 42.50 h |
| Regular hours | 40.00 h |
| Overtime hours | 2.50 h |
| Regular pay | $880.00 |
| OT pay (×1.5) | $82.50 |
| Gross pay | $962.50 |

Common Errors When Calculating Time Cards
---
What This Calculator Does NOT Include
| Not covered | Why it matters |
|---|---|
| Daily overtime (CA, AK, NV) | State law may owe you more than federal formula |
| Double time (2×) | California requires 2× pay after 12 hours/day or 8 hours on the 7th consecutive day |
| Paid time off / sick leave | PTO hours typically count toward gross pay but not toward overtime hours |
| Tips, commissions, or bonuses | Non-discretionary bonuses must be included in the "regular rate" for OT calculation under FLSA §207 |
| Taxes or deductions | Result is gross pay only — net take-home will be lower after federal/state withholding, FICA (7.65%), and any benefit deductions |
| Multiple pay rates | Employees working two roles at different rates require a blended rate calculation |

Who Is "Non-Exempt"?
The FLSA overtime rule applies to non-exempt workers. Employees classified as exempt (executive, administrative, professional, or certain computer/sales roles earning above a salary threshold — currently $684/week as of 2024) are not entitled to overtime pay by federal law. If you are salaried, confirm your classification before relying on overtime calculations.
---
Rounding Rules
Many employers round clock-in/out times to the nearest 5, 6, or 15 minutes. The FLSA permits rounding only if it averages out neutrally over time — it cannot systematically favor the employer. If your paycheck consistently reflects fewer hours than you worked, rounding practices may warrant review.
