The FLSA 7-minute rule, in 60 seconds
The U.S. Department of Labor (DOL) allows employers to round employee time to the nearest quarter-hour for payroll, provided the rounding is neutral over time — meaning it can’t consistently disadvantage employees. The most common implementation:
- Punches within 1–7 minutes of a quarter-hour mark round down to the prior quarter-hour.
- Punches at 8–14 minutes round up to the next quarter-hour.
Example: an employee clocks in at 8:53. That’s 7 minutes before 9:00 → rounds to 9:00 (a 7-minute “loss” for the employee). They clock out at 17:08 → that’s 8 minutes after 17:00 → rounds to 17:15 (a 7-minute “gain”). Net: balanced over time.

How this calculator handles each rule
The rounding chip you select is applied to the final decimal hours, not the punches themselves. That’s the most common implementation in modern payroll software (ADP, Gusto, Rippling, BambooHR all do it this way) because it gives you a clean decimal number for downstream multiplication.
- Exact — no rounding. Use only for engineering or research time tracking.
- Quarter (0.25) — classic 15-minute rounding. Strict mathematical “round half up.”
- DOL 7-min — identical to Quarter for our calculator’s implementation, applied to the decimal total. The 7-minute distinction matters when you round the punches, not the totals.
- Tenths — 6-minute (0.1 hr) increments. Found on legacy mainframe payroll.
- Hundredths — 0.01 hr precision. Used for billable-hour invoicing where dollar amounts are derived later.
Worked example: a typical shift
A retail worker clocks in at 09:07 and out at 17:53, with a 30-minute lunch break.
- Total elapsed: 17:53 − 09:07 = 8 h 46 m
- Less unpaid lunch: 8 h 46 m − 30 m = 8 h 16 m
- Decimal: 8.267 hr
- DOL 7-min rounded: 8.25 hr (rounds down because .267 is closer to .25)
- At $18.50/hr: 8.25 × $18.50 = $152.63 gross
What’s NOT included (intentionally)
This calculator computes straight-time pay only. To get to net pay you need to subtract:
- Federal, state, and local income tax (varies by jurisdiction and W-4)
- FICA/Medicare (currently 7.65% combined)
- Pre-tax deductions (401(k), HSA, FSA)
- Post-tax deductions (Roth 401(k), garnishments)
- Overtime premium (calculated weekly, not per-shift)
For tax withholding, use a payroll provider or the IRS withholding estimator. Our scope is the time → hours → straight-pay portion.
Frequently asked questions
Is rounding mandatory under FLSA?
No. Employers may round, but they don’t have to. Some employers pay to-the-minute. Rounding is allowed only because it was historically needed for paper time clocks — modern systems can do exact math just as easily.
Which rounding rule does my employer use?
Check your paystub or employee handbook. If unclear, ask payroll. The choice should be documented in writing — and applied consistently to all employees.
What about California / state-specific rules?
California courts have moved away from accepting time rounding (See's Candy v. Superior Court was the historical green light, but more recent decisions like Camp v. Home Depot have narrowed it). If you’re calculating California payroll, lean toward exact-minute methods. Consult an employment attorney for current guidance.
