The rule in one sentence
If a clock punch is within 7 minutes of a quarter hour, round it to that quarter hour. If it is 8 minutes or more away, round to the next quarter hour.
Quarter-hour breakpoints
Each hour is split into four quarters: :00, :15, :30, :45. The split point between two quarters falls at 7.5 minutes, which is why the rule works on the 7/8 boundary.
| Actual punch | Distance from :00 | Rounded to | Why |
|---|---|---|---|
| 8:03 | 3 min | 8:00 | Within 7 min, round down |
| 8:07 | 7 min | 8:00 | Exactly 7, round down |
| 8:08 | 8 min | 8:15 | 8 or more, round up |
| 8:14 | 14 min | 8:15 | Closer to next quarter |
| 8:22 | 7 min from :15 | 8:15 | Within 7 of :15 |
| 8:23 | 8 min from :15 | 8:30 | Round up to :30 |
Worked example
An employee clocks in at 7:53 AM and clocks out at 4:38 PM with a 30-minute lunch.
- 7:53 → 7:53 is 7 minutes after 7:45 → rounds down to 7:45.
- 4:38 → 4:38 is 8 minutes after 4:30 → rounds up to 4:45.
- Rounded shift: 7:45 AM to 4:45 PM = 9h 0m, minus 30m lunch = 8.50 paid hours.
Why employers use it
- Cleaner totals. Quarter-hour math is faster than minute-by-minute math.
- Decimal-friendly. Each quarter hour equals exactly 0.25 decimal hours.
- Standardized. The 7/8 split is widely understood and documented.
What the FLSA says
The Department of Labor allows employers to round time, provided the rounding "averages out" so employees are properly compensated over time. Rounding that always benefits the employer is not allowed.
Common pitfalls
- Rounding only clock-in down and clock-out up. That shaves time consistently and is non-compliant.
- Forgetting state restrictions. California courts have ruled against certain rounding practices for time worked.
- Combining rounding with auto-deducted lunches. Layered rounding can magnify errors.
Why the 7/8 split
Each 15-minute quarter has a midpoint at the 7.5-minute mark. The 7-minute rule rounds anything up to and including 7 minutes down to the previous quarter, and anything from 8 minutes up to the next quarter. The split is one minute earlier than a true halfway split because most U.S. payroll systems treat the 8-minute mark as the start of the next rounding bucket. Employers can choose to round at exactly 7.5 minutes if their software supports it, but the 7/8 convention is by far the most common.
Worked example: a clean week
A retail associate punches in and out at these times: 8:54 in / 5:03 out, 8:58 in / 5:11 out, 9:02 in / 5:07 out, 8:52 in / 5:00 out, 8:59 in / 5:14 out. Apply the 7-minute rule to each punch:
- 8:54 → 9:00 (6 minutes early rounds to the quarter); 5:03 → 5:00.
- 8:58 → 9:00; 5:11 → 5:15.
- 9:02 → 9:00; 5:07 → 5:00 (within 7 minutes).
- 8:52 → 8:45 or 9:00 depending on your bucket. Most systems push toward 9:00 because 8:52 is within 7 minutes of 8:45 and within 8 of 9:00, so it rounds to 8:45.
- 8:59 → 9:00; 5:14 → 5:15.

What auditors look for
If the Department of Labor reviews a rounding policy, they ask three questions: is the policy documented, is it applied consistently across employees, and does it average out over time. The last point is where many employers stumble. Periodic audits comparing rounded totals to actual minutes are the simplest defence.
Important note
The 7 minute rule is a common practice, not a guaranteed compliance method. Always confirm rounding rules with your employer's policy and applicable state law.
