Most US states default to the federal FLSA 40-hour weekly overtime rule. However, several states enforce daily overtime thresholds that are stricter. In these states, you may owe — or be owed — overtime even without exceeding 40 hours in a week.
| State | Daily OT — 1.5× | Daily OT — 2× | Weekly OT |
|---|---|---|---|
| CaliforniaStrictest | After 8 hrs/day | After 12 hrs/day | After 40 hrs/wk |
| Alaska | After 8 hrs/day | — | After 40 hrs/wk |
| Nevada | After 8 hrs/day (if wage < 1.5× state min wage) | — | After 40 hrs/wk |

| All other states | Federal only (no daily rule) | — | After 40 hrs/wk |
Payroll software (ADP, QuickBooks, Gusto, Rippling) stores time in decimal format for accurate pay multiplication. Divide any minute count by 60 to convert. Formula: Decimal Hours = Minutes ÷ 60
| Minutes | Decimal Hours | Common Usage |
|---|---|---|
| 5 min | 0.08 hrs | Quick break / 1/10 hour |
| 6 min | 0.10 hrs | 1/10 hour (legal/professional billing) |
| 10 min | 0.17 hrs | Short meeting |
| 15 min | 0.25 hrs | Quarter hour — most common rounding unit |
| 20 min | 0.33 hrs | Break time |
| 30 min | 0.50 hrs | Half hour / Lunch break |
| 40 min | 0.67 hrs | Extended meeting |
| 45 min | 0.75 hrs | Three-quarter hour |
| 50 min | 0.83 hrs | Near full hour |
| 60 min | 1.00 hrs | Full hour |
| 90 min | 1.50 hrs | Hour and a half |
| 120 min | 2.00 hrs | Two hours |
Under US federal regulations (29 CFR § 785.48), employers may round employee clock-in and clock-out times to the nearest quarter-hour (15 minutes), as long as the practice averages out to the employee's benefit over time and does not consistently favor the employer. This is known as the "7-minute rule":
| Actual Clock Time | Direction | Rounds To |
|---|---|---|
| 7:01–7:07 | Down (≤7 min past :00) | 7:00 |
| 7:08–7:14 | Up (≥8 min past :00) | 7:15 |
| 7:15–7:22 | Down (≤7 min past :15) | 7:15 |
| 7:23–7:29 | Up (≥8 min past :15) | 7:30 |
| 7:30–7:37 | Down (≤7 min past :30) | 7:30 |
| 7:38–7:44 | Up (≥8 min past :30) | 7:45 |
Some employers use 5-minute or 6-minute rounding instead of 15-minute rounding. The 6-minute interval is called "tenth-of-an-hour" rounding (0.1 hours = 6 minutes) and is standard in legal billing and professional services: 1–3 minutes rounds to :00; 4–9 minutes rounds to :06. This produces billing increments of 0.1, 0.2, 0.3 … hours rather than 0.25, 0.50, 0.75.
A single day's net hours = clock-out minus clock-in minus unpaid breaks. This is what you enter on a daily time card or submit to a project management tool. Relevant for freelancers billing per-project and shift workers.
FLSA overtime is calculated on a single workweek (any fixed, regularly recurring 7-consecutive-day period). Overtime does not carry across workweek boundaries — 45 hours in Week 1 and 35 in Week 2 means 5 overtime hours in Week 1, not zero just because the two-week average is 40.
A biweekly pay period covers exactly 2 weeks (80 hours at standard 40 hrs/wk). A semi-monthly pay period covers half a calendar month (~86.67 hours at 40 hrs/wk). Important: FLSA overtime is still calculated on the underlying workweeks within the pay period — not on the pay-period total.
9:00 AM – 5:00 PM, 3 projects, 30-minute lunch
Billable hours: 2.5 + 3.0 + 2.0 = 7.5 hrs (7.50 decimal)
10:00 PM → 6:00 AM, 30-minute break
Net hours: 8.00 − 0.50 = 7.5 hrs (7.50 decimal)
8:00 AM – 9:00 PM (13 hrs clock), 1 hr break = 12 net hours, rate $20/hr
Gross daily pay (CA): $280.00
Federal-only (FLSA) would pay: 12 × $20 = $240.00 — $40 less than California law requires.
Subtract the total break duration from your clock time: (End Time − Start Time) − Unpaid Break = Net Work Hours. For example: 9:00 AM to 5:00 PM is 8 hours clock time; minus a 30-minute unpaid lunch gives 7.5 net hours, or 7.50 in decimal format.
When the end time is earlier than the start time (e.g., starting at 10:00 PM and ending at 6:00 AM), the calculator automatically adds 24 hours to the end time before calculating the duration. 10:00 PM to 6:00 AM = 8 hours total. Enter your actual times and the calculator handles the midnight crossover.
Divide minutes by 60 to get decimal hours. Common conversions: 15 min = 0.25 hrs, 30 min = 0.50 hrs, 45 min = 0.75 hrs. Formula: Decimal Hours = Minutes ÷ 60. Payroll systems use decimal format because you can multiply decimal hours directly by the hourly rate without further conversion.
Under the federal Fair Labor Standards Act (FLSA), non-exempt employees are entitled to overtime pay at 1.5 times their regular rate for all hours worked over 40 in a single workweek (any fixed 7-day period). Overtime is not averaged across pay periods — a week with 45 hours always generates 5 overtime hours, regardless of whether the prior week had fewer hours.
California requires overtime for hours worked beyond 8 per day (at 1.5× rate) and beyond 12 per day (at 2× double-time rate), in addition to the standard 40-hour weekly threshold. This is stricter than federal FLSA, which has no daily limit. For example, if you work 10 hours in a single day in California, the first 8 hours are regular pay and the next 2 hours are overtime at 1.5× — even if your weekly total is under 40 hours.
Under 29 CFR § 785.48, employers may round employee clock times to the nearest quarter-hour (15 minutes). The '7-minute rule' means: if the actual time is 7 minutes or less past a quarter-hour, it rounds down to that quarter-hour; if it is 8 minutes or more past, it rounds up to the next quarter-hour. For example, clocking in at 7:07 rounds to 7:00; clocking in at 7:08 rounds to 7:15. This practice is only legal if it is neutral over time and does not systematically favor the employer.
Yes — use the Weekly Timesheet section to enter start time, end time, and break minutes for each day of the week. The tool calculates net hours per day, totals the week, and automatically flags FLSA overtime when the total exceeds 40 hours. You can also enter your hourly rate to see an estimated gross pay breakdown showing regular pay and overtime pay separately.
A biweekly pay period is every two weeks (26 pay periods per year, 80 hours at 40 hrs/wk per period). A semi-monthly pay period is twice per calendar month (24 pay periods per year, approximately 86.67 hours per period at 40 hrs/wk). Critically, FLSA overtime is still calculated on the underlying 7-day workweeks within the pay period — not on the pay-period total.
Start with your total daily work hours, then subtract non-billable time (internal admin, invoicing, project management, travel between clients). The remaining hours are billable to the client. Industry benchmarks suggest 65–80% billable utilization for a sustainable solo practice. Use the Billable vs Non-Billable section in this calculator after you calculate your daily hours.
This calculator uses standard decimal hour conversion (minutes ÷ 60) and FLSA overtime logic, which matches the format accepted by ADP, QuickBooks, Gusto, Rippling, and most payroll systems. It is suitable for estimating your hours and identifying overtime eligibility. For the official payroll record your employer submits to tax authorities, always verify figures through your company's payroll provider or HRIS system.
The calculator includes overtime reference standards for: United States (FLSA, 40 hrs/wk), United Kingdom (Working Time Regulations, 48 hrs/wk), European Union (Working Time Directive, 48 hrs/wk), India (Factories Act, 9 hrs/day or 48 hrs/wk), Australia (Fair Work Act, 38 hrs/wk), Canada (Canada Labour Code, 44 hrs/wk federal), UAE (Federal Labour Law, 8 hrs/day or 48 hrs/wk), and Singapore (Employment Act, 44 hrs/wk). Each includes a direct source link to the official government reference.
