7-minute rule calculator

How to use the 7-minute rule calculator

• Rounding is already set to Nearest 15 minutes (7-minute rule).
• Type your exact punches from the time clock, such as 7:53 and 4:07p.
• Enter unpaid break minutes, or switch to lunch punches if you clock out for lunch. Lunch punches are rounded too. Break minutes are not.
• Read the rounded total. Then set Rounding to None to see your exact total. The difference is what rounding added or took away this week.
• Save both versions as PDFs if you want to compare them over several weeks.

Quarter-hour rounding table

Look at the minutes past the last quarter hour (:00, :15, :30 or :45).

Worked example: rounding versus exact time

Here is one week with a 30-minute unpaid lunch each day. The rounded column is what the calculator shows with 15-minute rounding. The exact column is what it shows with rounding off.

Monday: 7:53 rounds up to 8:00 (8 minutes past 7:45). 4:07 rounds down to 4:00. Rounded, the day is 8:00 − 0:30 = 7:30. Exact, it is 8:14 − 0:30 = 7:44.

Thursday: 7:52 rounds down to 7:45 (7 minutes past). 4:00 stays. Rounded, the day is 8:15 − 0:30 = 7:45. Exact, it is 8:08 − 0:30 = 7:38. Here rounding gave 7 extra minutes.

Rounded total: 7:30 + 8:00 + 7:45 + 7:45 + 7:30 = 38:30, or 38.50 hours. Exact total: 7:44 + 8:00 + 7:45 + 7:38 + 7:35 = 38:42, or 38.70 hours. This week, rounding cost 12 minutes. In another week it may add time. The point of the rule is that it should even out.

What the law says about rounding

There is no federal law called the 7-minute rule. It is the common name for quarter-hour rounding under 29 CFR 785.48. That regulation says employers have long recorded start and stop times "to the nearest 5 minutes, or to the nearest one-tenth or quarter of an hour". It accepts the practice as long as it doesn't result, over a period of time, in failing to pay employees for all the time they actually worked.

The Department of Labor's Fact Sheet #53 spells out the quarter-hour version: time from 1 to 7 minutes may be rounded down, and time from 8 to 14 minutes must be rounded up. It also warns that an employer may violate minimum wage and overtime rules if it always rounds down.

So the test is fairness over time. Rounding that goes both ways and averages out is accepted. Rounding that consistently favors the employer is not.

How the calculation works

Each punch is rounded on its own, before the day is added up. The calculator looks at the minutes past the last step. With a 15-minute step, 7 or fewer round down and 8 or more round up.

The 5-minute and 6-minute options work the same way. With 6 minutes (a tenth of an hour), 1 to 2 minutes round down and 3 to 5 round up. With 5 minutes, 1 to 2 round down and 3 to 4 round up.

After rounding, the day is out minus in, minus unpaid break minutes. Overnight shifts, overtime and pay work just as they do with rounding off. Decimal hours are total minutes ÷ 60.

5-minute and 6-minute rounding

Some employers round to a smaller step. The regulation names the nearest 5 minutes and the nearest tenth of an hour as well as the quarter hour. Here is how the calculator rounds with each step.

Check rounding over several weeks

One week tells you little. To see if rounding evens out, enter each week's real punches, write down the rounded and exact totals, and keep a running difference. Download the PDF each week so you have the punches on record.

If the difference keeps growing in the same direction, bring your notes to your employer or payroll team. If it swings both ways and stays small, the rounding is probably working as intended.

Common mistakes with the 7-minute rule

• Rounding the daily total instead of each punch. Payroll systems that use the 7-minute rule round the punches. Rounding the total gives a different answer.
• Thinking 7 minutes late is free. Rounding is about recording time, not about attendance rules. Your employer can still have a lateness policy.
• Only rounding one way. If early clock-ins always round up to the start time but late clock-outs never round up, that pattern can favor the employer.
• Comparing one week. One week can go either way. Compare several weeks with rounding on and off.
• Ignoring work before the shift. Rounding only covers punch times. Work you actually did is hours worked, and the de minimis rule in 29 CFR 785.47 does not let an employer ignore regular work time, however small.

Legal basics

This is general information, not legal advice. The calculator shows how rounding changes your hours. It can't tell you whether your employer's policy is lawful, and state law may also apply.

Under 29 CFR 785.48, time clocks are not required. If you clock in early or stay late on your own and don't work, that time doesn't have to be paid. If you do work, it counts.
