What the regulation says
29 CFR 785.48(b) addresses “rounding” practices. It recognises the practice, used for many years, of recording employees' starting and stopping time to the nearest 5 minutes, or to the nearest one-tenth or quarter of an hour. It treats this as acceptable for enforcement purposes where the practice is applied in a way that will not result, over a period of time, in failure to compensate the employees properly. In other words, rounding is allowed when it is neutral: sometimes up, sometimes down, and on average it does not cost workers time.
The regulation does not use the phrase “7-minute rule”. That is the common name for how quarter-hour rounding works in practice (below). The rule also does not say your state allows rounding: states may have their own limits, so check your state labor department.
How the 7-minute rule works
With a quarter-hour grid, the marks are :00, :15, :30 and :45. A punch within 7 minutes of a mark rounds to that mark; a punch 8 minutes or more past a mark rounds forward to the next one. Rounding to 5 minutes and 6 minutes (tenths of an hour) works the same way with a smaller grid. Use the time rounding calculator to test your own punches.
| Actual punch | Rounded (15 min) | Effect on paid time |
|---|---|---|
| In at 7:52 am | 7:45 am | +7 min paid |
| In at 7:53 am | 8:00 am | -7 min paid |
| In at 8:07 am | 8:00 am | +7 min paid |
| In at 8:08 am | 8:15 am | -7 min paid |
| Out at 5:07 pm | 5:00 pm | -7 min paid |
| Out at 5:08 pm | 5:15 pm | +7 min paid |
A fairness test with real numbers
Is this rounding neutral?
An employee arrives early to get ready and clocks in at 7:53 every morning and out at exactly 4:30. The 7:53 punch is 8 minutes past 7:45, so it rounds up to 8:00 and the employee loses 7 minutes of paid time a day. Over 20 days that is 140 minutes (2 hours 20 minutes) of unpaid work, worth $46.67 at $20.00/hour. If the same employee clocked in at 7:52 instead, the punch would round down to 7:45 and gain 7 minutes. Rounding is neutral only if both kinds of punches appear about equally. If most punches fall where rounding goes against the employee — for example when workers must clock in a few minutes early to get ready — the rounding shortchanges them every day.
What to do: keep a log of actual punches for a month, total the rounded and unrounded hours using the time card calculator, and see which way the difference runs. A persistent gap in one direction is the pattern the regulation's “over a period of time” language is aimed at.
Common questions employers and employees ask
- Can the employer always round down? Rounding that systematically favors the employer is the practice that attracts scrutiny; the regulation's condition is that it does not result in failure to compensate employees properly over time.
- Should rounding apply to start and end, or to the total? The regulation speaks of recording starting and stopping time; punch rounding is the standard application. Rounding a total can distort overtime differently.
- What about rounding that crosses the 40-hour line? Overtime depends on the rounded hours your employer pays; a few minutes can mean a few overtime minutes. See the example in the overtime calculator.
- Do states ban rounding? Some may; we only publish what we can cite, so check your state labor department's guidance.
Tips for employees and small employers
- Employees: keep your own record and compare it to the pay stub every period.
- Employers: if you round, document the rule, apply it to every punch in both directions and audit periodically with a sample of real punches.
- If time to the minute is practical, many employers simply pay to the minute, which avoids the question.
A full week of examples
| Day | Actual in / out | Rounded (15 min) | Actual paid (30 min meal) | Rounded paid |
|---|---|---|---|---|
| Mon | 7:58 / 4:32 | 8:00 / 4:30 | 8:04 | 8:00 |
| Tue | 8:09 / 4:36 | 8:15 / 4:30 | 7:57 | 7:45 |
| Wed | 7:51 / 4:44 | 7:45 / 4:45 | 8:23 | 8:30 |
| Thu | 8:03 / 5:12 | 8:00 / 5:15 | 8:39 | 8:45 |
| Fri | 8:00 / 4:25 | 8:00 / 4:30 | 7:55 | 8:00 |
This week: actual 40:58; rounded 41:00. Individual days move up or down, but the total is within two minutes. This is what a neutral rounding policy looks like. If every row of a real week went the same way, you would need to question the policy.
Alternatives to rounding
- Pay to the minute. Modern systems calculate exact minutes; it is simple to explain.
- Grace periods with exact pay. Allow a short window for attendance policy without changing pay.
- Rounding in tenths. Round to 6 minutes so each entry is a one-decimal number, if the policy is neutral.
