Time clock rounding rules and the 7-minute rule

Is time clock rounding legal?

Yes under federal law, as long as it's neutral. The Department of Labor's rule, 29 CFR 785.48(b), accepts recording start and stop times "to the nearest 5 minutes, or to the nearest one-tenth or quarter of an hour," provided the practice doesn't, over a period of time, fail to pay employees for all the time they actually worked.

In practice that means two things:

• Round to the nearest mark, both ways. Each punch goes to whichever increment is closer, so some round up and some round down.
• No net loss over time. If rounding pays employees less than their exact punches week after week, it fails, even if the rule looks neutral on paper.

Rounding is a permission, not a requirement. Many employers now pay to the minute, since modern clocks capture it exactly, and some states are stricter than federal law; California is covered below.

The 7-minute rule

The 7-minute rule is quarter-hour rounding: a punch 1 to 7 minutes after a quarter hour rounds back to it, and a punch 8 to 14 minutes after rounds forward to the next one. It works because 7.5 minutes is the midpoint of a 15-minute block.

• Clock in at 7:07, recorded as 7:00: the employee gains 7 paid minutes.
• Clock in at 7:08, recorded as 7:15: the employee loses 7 paid minutes.
• Clock out at 3:37, recorded as 3:30; clock out at 3:38, recorded as 3:45.

The rule applies to every punch, in and out. It isn't a grace period for lateness, and it doesn't let an employer skip the first 7 minutes of work.

15-minute rounding chart

Under quarter-hour rounding, every punch lands on :00, :15, :30 or :45. The quick version:

The full chart shows how far each punch moves. The same pattern repeats after every quarter hour.

Whether a move helps or hurts depends on the punch. Moving a clock-in earlier, or a clock-out later, adds paid time; moving a clock-in later, or a clock-out earlier, removes it. The time rounding calculator rounds a whole week of punches for you.

5, 6 and 10-minute rounding

Smaller increments work the same way, rounding to the nearest mark, and move each punch less, so they're easier to keep neutral.

Tenth-of-an-hour rounding is popular because each step is 0.1 hours, which goes straight into payroll (see minutes to decimal). The regulation names 5 minutes, a tenth and a quarter of an hour. Ten-minute rounding isn't named, so if you use it, expect it to be judged by the same neutrality test.

What makes rounding illegal

Rounding becomes illegal when it consistently favors the employer. These patterns fail:

• One-way rounding. Rounding every clock-in up and every clock-out down, or always rounding to the scheduled start time.
• Rounding away real work. Requiring people to be working at 6:53 but rounding their 6:53 punch to 7:00 every day.
• Lopsided results. A rule that's neutral on paper but, because of how people actually punch, cuts paid time week after week.

A worked example: a worker punches in at 6:53 and out at 3:07 every day, with an unpaid 30-minute lunch, and starts working as soon as they punch in.

• Exact time: 6:53 to 3:07 is 8 hours 14 minutes, minus 30 minutes, so 7 hours 44 minutes.
• Quarter-hour rounding: 7:00 to 3:00 is 8 hours, minus 30 minutes, so 7 hours 30 minutes.
• Lost per day: 14 minutes. Over 250 workdays: 3,500 minutes, or about 58 hours of unpaid work.

That's a neutral-looking rule producing a one-sided result, because this worker's habits always land on the losing side.

Early and late punches are a separate question. Under 29 CFR 785.48(a), if employees voluntarily punch in early or out late and don't do any work in that time, the extra minutes can be disregarded. The test is whether they're working, not when they punched.

Time clock rounding rules in California

California allows neutral rounding in principle, but it's riskier there than anywhere else, and meal-period punches can't be rounded at all.

• See's Candy Shops v. Superior Court (2012). A California Court of Appeal accepted a neutral rounding policy modeled on the federal rule.
• Donohue v. AMN Services (2021). The California Supreme Court held that employers can't round meal-period punches, and that time records showing a short or late meal period create a presumption of a violation that the employer has to rebut. A 29-minute lunch rounded to 30 is still a 29-minute lunch.
• Camp v. Home Depot (2022). A Court of Appeal held that an employer whose system captured every minute had to pay for all of it, even under a facially neutral rounding policy. The California Supreme Court agreed to review the case in 2023, and it was still pending when we last checked in October 2026, so look for a decision before relying on rounding in California.

California also has daily overtime, so a few minutes moved across the 8-hour line can change the overtime owed; see California overtime rules. The practical answer for California employers is to pay from exact punches. If you round at all, never round meal-period punches, and test the results regularly.

Can my employer round my time?

In most states, yes, if the rounding is neutral: sometimes in your favor, sometimes not, and even over time. Your employer can't round in only one direction, round away minutes you spent working, or use rounding that keeps shorting you.

If you think rounding is costing you, write down your real punch times for a few weeks and compare them with your pay stubs. If the difference always runs one way, raise it with payroll. If that doesn't fix it, contact your state labor department or the US Department of Labor's Wage and Hour Division (1-866-487-9243).

Best practice: keep raw punches, round only in the pay calculation

The safest setup is to store every punch exactly as it happened and apply rounding only when hours are totaled for pay, or not to round at all.

• You can prove neutrality. With exact punches, you can compare rounded and exact totals for any person over any period.
• You can stop rounding later without losing any history.
• Corrections stay honest. Edits are made to the punch, with a record of who changed what.

Once a quarter, compare each employee's total exact minutes with their total rounded minutes. If anyone is consistently behind, fix the policy and pay the difference. Rounding also matters for recordkeeping: the FLSA requires records of hours worked each workday and workweek (see FLSA recordkeeping requirements).

TrackBadges works this way: rounding to 5, 10 or 15 minutes is a timesheet setting, the raw scan times are never changed, and every edit keeps a history, so you can turn rounding off at any time and every exact punch is still there.
