Time clock rounding rules
What federal law allows, what the 7-minute rule means, and how to check whether rounding is costing you.
Can employers round time clock punches?
Yes, as long as the rounding doesn't shortchange employees over time (29 CFR 785.48(b)). Federal rules allow rounding to the nearest 5 minutes, tenth of an hour (6 minutes), or quarter hour. With quarter-hour rounding, 1 to 7 minutes rounds down and 8 to 14 rounds up. That is the 7-minute rule.
What the regulation says
29 CFR 785.48(b) accepts the common practice of recording start and stop times to the nearest 5 minutes, tenth of an hour, or quarter hour. The condition is that, over time, the practice must not lead to employees being underpaid for the time they actually worked. This is usually called the neutrality requirement.
The regulation doesn't require rounding. Many employers pay to the minute, and modern time clocks make that easy.
The 7-minute rule is just "nearest quarter hour"
A quarter hour is 15 minutes. Any punch falls somewhere between two quarter-hour marks. If it is 7 minutes or less past a mark, the earlier mark is closer. If it is 8 minutes or more past, the later mark is closer. Nothing about it is a separate law. It is what "nearest" means when you count in whole minutes.
| Minutes past the quarter hour | Rounds to |
|---|---|
| 0–7 | the earlier quarter hour |
| 8–14 | the next quarter hour |
So 8:07 rounds to 8:00 and 8:08 rounds to 8:15. At the end of the day, 4:52 rounds to 4:45 and 4:53 rounds to 5:00.
5-minute and 6-minute rounding
| Increment | Rounds down | Rounds up |
|---|---|---|
| 5 minutes | 0–2 minutes past | 3–4 minutes past |
| 6 minutes (1/10 hour) | 0–2 minutes past | 3–5 minutes past |
With 6-minute rounding, a punch exactly 3 minutes past the mark sits halfway between. This calculator rounds halves up, so 8:03 becomes 8:06. Some payroll systems round that midpoint down. If your numbers differ from your employer's by a few minutes, this is the first thing to check.
Neutral rounding: a worked example
Quarter-hour rounding on each punch, with a 30-minute unpaid lunch that isn't rounded.
| Day | Actual in | Actual out | Actual hours | Rounded in | Rounded out | Rounded hours | Difference |
|---|---|---|---|---|---|---|---|
| A | 7:53 AM | 4:07 PM | 7:44 | 8:00 AM | 4:00 PM | 7:30 | −14 min |
| B | 8:07 AM | 4:08 PM | 7:31 | 8:00 AM | 4:15 PM | 7:45 | +14 min |
The math for day A: 4:07 PM − 7:53 AM = 8 hours 14 minutes, minus 30 minutes = 7:44. Rounded: 8:00 to 4:00 is 8:00, minus 30 = 7:30. The math for day B: 4:08 PM − 8:07 AM = 8 hours 1 minute, minus 30 = 7:31. Rounded: 8:00 to 4:15 is 8:15, minus 30 = 7:45.
Over the two days, the employee loses 14 minutes and gains 14 minutes. That is what neutral rounding looks like. If a full month of punches showed the employee losing time nearly every day, the practice would fail the neutrality test even though each single rounding follows the rule.
Rounding that isn't neutral
- Rounding only one way. A policy that always rounds down, or rounds in the employer's favor only, doesn't average out.
- Rounding clock-ins but not clock-outs, or the reverse, when punches cluster on one side. If everyone clocks in 5 minutes early and the clock-in rounds forward, those minutes are lost every day.
- Requiring work before the rounded start time. If you start working at 7:53, the 7 minutes count as work time whatever the rounding says.
29 CFR 785.48(a) adds a related point. If an employee punches in early or out late but does no work in that time, the employer doesn't have to pay for those minutes. If the employee does work, it counts.
Each punch or the daily total
This calculator can round each punch (the approach 785.48(b) describes) or round the day's total. Using the days above with daily-total rounding to 15 minutes, day A's 7:44 becomes 7:45 and day B's 7:31 becomes 7:30. The difference shrinks to 1 minute a day either way. Match whichever method your employer uses.
California
California is stricter in practice. In Donohue v. AMN Services (2021), the California Supreme Court held that employers can't round time punches for meal periods, and that time records showing short or late meal periods create a presumption of a violation. Later California cases have also questioned rounding where an employer can record exact times. If you work in California, check current guidance from the Labor Commissioner's Office before relying on any rounding.
How the calculator handles rounding
Rounding is off by default, because exact minutes are always accurate. When you turn it on, punches are rounded to the nearest 5, 6, or 15 minutes, with halves rounded up. Overnight punches are rounded on the same continuous clock, so 11:53 PM rounds to midnight cleanly. The calculator never offers "always round down".

Frequently asked questions
Is the 7-minute rule a law?
Not by that name. Federal rules allow rounding to the nearest quarter hour (29 CFR 785.48(b)), and at whole-minute precision, nearest means 1 to 7 minutes rounds down and 8 to 14 rounds up. The 7-minute rule is the everyday name for that.
Can my employer always round down?
No. Rounding is allowed only if it averages out so employees are paid for all the time they actually work. A policy that always rounds down, or only ever in the employer's favor, fails that test.
Is time clock rounding legal in California?
It is under heavy scrutiny. The California Supreme Court barred rounding of meal period punches in Donohue v. AMN Services (2021), and later cases have questioned rounding where exact times are recorded. Check current guidance from the California Labor Commissioner's Office.
Do I get paid if I clock in early?
Only for time you actually work. If you clock in early but don't start working, federal rules let the employer leave those minutes out (29 CFR 785.48(a)). If you start working, that time counts and must be paid.
What rounding does the calculator use by default?
None. Totals use the exact minutes you enter. Turn on 5-, 6-, or 15-minute rounding only to match your employer's records.
