Quick answer: Under federal law, employers may round employees’ clock-in and clock-out times to the nearest 5 minutes, tenth of an hour (6 minutes) or quarter hour (15 minutes), but only if the rounding is neutral. That means it averages out over time so employees are paid for all the time they actually worked.
With quarter-hour rounding, known as the 7-minute rule, 1 to 7 minutes round down and 8 to 14 minutes round up. So 8:07 becomes 8:00, and 8:08 becomes 8:15.
Rounding that always favors the employer is illegal. California applies stricter rules.

What is time clock rounding?
Time clock rounding is when an employer adjusts recorded punch times to a set interval before calculating pay. For example, a punch at 7:56 AM becomes 8:00 AM. It dates back to paper punch clocks, when adding up odd minutes by hand took a lot of time.
The federal Fair Labor Standards Act (FLSA) doesn’t require rounding, but it allows it under the conditions in 29 CFR 785.48(b).
Federal time rounding rules
Under federal regulations, a rounding practice is acceptable only if all of these are true:
- It uses a permitted interval: the nearest 5 minutes, the nearest tenth of an hour or the nearest quarter hour.
- It is neutral as written: times are rounded to the nearest interval, both up and down, for both clock-in and clock-out.
- It is neutral in practice: over a period of time, employees are fully paid for the time they actually work. A policy that looks neutral on paper but consistently shaves time in practice can still violate the law.
Rounding only changes how recorded time is counted. If an employee is actually working, for example setting up a register before the shift, that time must be paid, whatever the rounding policy says.
The 7-minute rule (quarter-hour rounding)
Quarter-hour rounding is the most common method. Because 7.5 minutes is the midpoint of a 15-minute interval, punches 1 to 7 minutes past a quarter hour round down, and punches 8 to 14 minutes past round up.
| Actual punch (minutes past the hour) | Rounds to | Decimal hours |
|---|---|---|
| :53 to :07 | :00 | .00 |
| :08 to :22 | :15 | .25 |
| :23 to :37 | :30 | .50 |
| :38 to :52 | :45 | .75 |
Examples:
- 7:53 becomes 8:00.
- 8:07 becomes 8:00.
- 8:08 becomes 8:15.
- 4:37 PM becomes 4:30 PM.
- 4:38 PM becomes 4:45 PM.
Tenth-hour and 5-minute rounding
| Method | Interval | How it rounds | Example |
|---|---|---|---|
| Quarter hour | 15 minutes | 1–7 min down, 8–14 min up | 9:08 → 9:15 |
| Tenth of an hour | 6 minutes (0.1 hour) | To the nearest 6-minute mark; 3 minutes past usually rounds up | 9:02 → 9:00, 9:04 → 9:06 |
| 5 minutes | 5 minutes | 1–2 min down, 3–4 min up | 9:02 → 9:00, 9:03 → 9:05 |
Smaller intervals mean less difference from actual time, which makes them easier to defend. Larger intervals, such as rounding to the nearest 30 minutes, are not among the intervals recognized in federal regulations and are very likely to underpay employees.
Example: a neutral rounding policy over one week
Here is one employee’s week under quarter-hour rounding. A positive number means the rounded time paid the employee more than the actual punches; a negative number means less.
| Day | Clock in → rounded | Clock out → rounded | Net effect |
|---|---|---|---|
| Mon | 7:56 → 8:00 (−4 min) | 4:33 → 4:30 (−3 min) | −7 min |
| Tue | 8:05 → 8:00 (+5 min) | 4:40 → 4:45 (+5 min) | +10 min |
| Wed | 7:52 → 7:45 (+7 min) | 4:29 → 4:30 (+1 min) | +8 min |
| Thu | 7:58 → 8:00 (−2 min) | 4:36 → 4:30 (−6 min) | −8 min |
| Fri | 8:02 → 8:00 (+2 min) | 4:27 → 4:30 (+3 min) | +5 min |
| Week total | +8 min | ||
Some days the employee gained minutes and some days they lost minutes. Over the week, the policy balanced out. This is what a neutral policy looks like.
When time rounding is illegal
- One-way rounding: rounding clock-ins up and clock-outs down, for example 7:53 to 8:00 while 8:03 goes to 8:15.
- Rounding that shaves time in practice: for example, when employees must be at their stations by 8:00, so they always clock in a few minutes early and those minutes are always rounded away.
- Rounding while the employee is working: minutes spent performing work must be paid, even if the punch would round them off.
- Using rounding to discipline tardiness: docking 15 minutes of pay for clocking in at 8:02 goes beyond neutral rounding. Employers can discipline lateness in other ways, but not by withholding pay for time worked.
What about clocking in early or out late?
Federal rules don’t require pay for small amounts of time when employees voluntarily clock in early or clock out late without working, such as punching in and then chatting or having coffee before the shift. If the employee does any work during that time, it must be paid.
Many employers handle this with a clear policy: no clocking in more than a few minutes before the shift, and no work before clocking in.
State rules: California is stricter
Most states follow the federal standard, but California courts have limited rounding:
- Meal breaks: In Donohue v. AMN Services (2021), the California Supreme Court held that employers may not round meal period punches. A rounded record showing a short or late meal break can expose the employer to meal period premium pay.
- Rounding in general: California courts have traditionally allowed neutral rounding. In Camp v. Home Depot, however, a California appeals court questioned whether rounding is lawful when an employer can easily record exact time. The California Supreme Court agreed to review the case, and as of mid-2026 it had not issued a decision.
Given this uncertainty, many California employers now pay to the exact minute.
Some union contracts and state rules in other industries also restrict rounding. Check your state’s labor law page and any employment agreement that applies to you.
Best practices for employers
- Consider not rounding at all. Modern time clock apps record exact minutes, which removes most of the legal risk.
- If you round, round to the nearest interval, both up and down, for every punch, and put the policy in writing.
- Audit regularly. Compare rounded and actual time across all employees, for example every quarter. If employees consistently lose time, change the policy and pay back the difference.
- Never round meal break punches, especially in California.
- Control early clock-ins with a policy, not with rounding, and make sure no one works off the clock.
Tips for employees
- Ask for your employer’s written rounding policy.
- Keep your own record of actual punch times for a few pay periods, then compare it with your pay stubs using our time card calculator.
- If rounding consistently reduces your pay, raise it with HR first. If that doesn’t resolve it, contact your state labor department or the U.S. Department of Labor’s Wage and Hour Division.
Frequently asked questions
Is the 7-minute rule a law?
Not exactly. The 7-minute rule is the common name for rounding to the nearest quarter hour, which federal regulations allow as long as it is neutral and employees are paid for all time actually worked. Employers are not required to round at all.
Can my employer always round my time down?
No. Rounding must go to the nearest interval, both up and down. A policy that always rounds in the employer’s favor violates federal law.
Can an employer round to the nearest 30 minutes?
Federal regulations recognize rounding to the nearest 5 minutes, tenth of an hour or quarter hour. A 30-minute interval is not among them and is very likely to result in unpaid work time.
Is time rounding legal in California?
Neutral rounding of start and end times has traditionally been allowed, but meal period punches may not be rounded. The California Supreme Court is reviewing whether rounding is lawful when an employer can track exact time (Camp v. Home Depot). Until it rules, paying to the minute is the safest approach.
Does rounding affect overtime?
Yes. Overtime is based on total hours worked in the workweek, so rounded minutes can push hours above or below 40. Because the policy must average out over time, it must not systematically reduce overtime hours. See how to calculate overtime.
Should I write rounded times on my time card?
No. Always record your actual times and let your employer apply its rounding policy. See our guide on how to fill out a time card.
