If I clock in at 8:07, does my employer pay from 8:00 or 8:15?
From 8:00. A punch at 8:07 rounds down to the top of the hour. Walk in at 8:08 and the same rule rounds you up to 8:15. That split is the whole point of the 7-minute rule: it draws a symmetrical line halfway through each quarter-hour block so the rounding can be neutral over time.
The Fair Labor Standards Act (FLSA) of 1938 permits rounding, but only if it does not systematically favour the employer. Shave seconds off every shift and you have a wage claim. Let the ups and downs cancel out across a pay period and you have a legal system.
How the 7-minute break point actually works
Every quarter-hour block has a midpoint. For the block starting at :00, that midpoint sits at 7 minutes 30 seconds. The rule splits it at 7 for simplicity:
| Actual punch (minutes past the hour) | Rounds to |
|---|---|
| :00 to :07 | :00 |
| :08 to :22 | :15 |
| :23 to :37 | :30 |
| :38 to :52 | :45 |
| :53 to :59 | :00 (next hour) |
The name comes from that 7-minute marker. Zero through seven past the quarter go down; eight through fourteen go up. A punch at 12:07 becomes 12:00. A punch at 12:08 becomes 12:15. Both shift by 7 minutes. Symmetrical.
Rounding to the closest 5, 6, or 15-minute increment
The FLSA names three acceptable intervals. None is mandatory.
Closest 5-minute mark. Break point at 2.5 minutes. A punch at 8:02 rounds to 8:00; 8:03 rounds to 8:05. This produces decimal values: 0.08 (5 minutes), 0.17 (10 minutes), 0.25 (15 minutes), and so on through 0.92 (55 minutes).
Closest 6-minute mark. Break point at 3 minutes. Standard in legal billing because six minutes is exactly 0.10 of an hour. A 0.1-hour block. The same neutrality test applies.
Closest 15-minute mark. The 7-minute rule. Break point at 7.5 minutes, applied as 7 down, 8 up. Produces clean quarter-hour decimals: 0.25, 0.50, 0.75. This is the most common choice for hourly payroll.
Every increment works the same way: pick a midpoint, round toward the nearer boundary, and audit the totals.
When rounding violates federal law
Neutrality is the only test that matters. Over a pay period, the minutes added and the minutes subtracted must approach zero. A system that always rounds down fails. A system that rounds down by 10 minutes and up by 4 fails.
The Department of Labor looks at the pattern. One bad day is not a violation. A consistent lean is.
Examples that break the rule:
- Rounding every clock-in down and every clock-out down.
- Using a 10-minute break point for quarter-hour rounding (0 to 10 down, 11 to 14 up).
- Rounding only late arrivals but never early departures.
The 7-minute rule is not a licence to round down at 7 past. It rounds down from :00 to :07 and up from :08 to :14. If your payroll system only ever subtracts, you are stealing time.
Two days of rounding that pass the neutrality test
Day one: - 8:03 → 8:00 (minus 3 minutes) - 12:11 → 12:15 (plus 4 minutes) - 12:58 → 13:00 (plus 2 minutes) - 17:07 → 17:00 (minus 7 minutes)
Net: minus 4 minutes. Small.
Day two: - 7:53 → 8:00 (plus 7 minutes) - 12:22 → 12:15 (minus 7 minutes) - 13:00 → 13:00 (exact) - 17:08 → 17:15 (plus 7 minutes)
Net: plus 7 minutes. Across both days the error is plus 3 minutes. That cancels over a fortnight.
Why paper timesheets cause more rounding violations than software
Digital time clocks apply the rule the same way every time. Set the increment, set the break point, and the arithmetic does not drift. Manual timesheets drift constantly. A manager glances at 8:06 and writes 8:00, then glances at 8:08 and also writes 8:00. That is asymmetric. Repeat it across ten employees and the liability compounds.
Most payroll software lets you pull a report comparing raw punches to rounded values. Run it for one pay period. Sum the differences. If the total leans more than 15 minutes in either direction, the rounding is not neutral.
If you process payroll by hand, use a work hours calculator that applies the same break point to every entry. Never round by eye.
