Quick answer: US federal rules let employers round clock-in and clock-out times to the nearest 5 minutes, tenth of an hour (6 minutes) or quarter hour (15 minutes), as long as the policy rounds both up and down and, over time, pays employees for all the time they actually work (29 CFR 785.48(b)). With quarter-hour rounding, the 7-minute rule applies: 1 to 7 minutes past an increment rounds down, 8 to 14 minutes rounds up.
What time clock rounding is
Time clock rounding means recording a punch at the nearest set increment instead of the exact minute. A clock-in at 8:07 becomes 8:00 under quarter-hour rounding, and a clock-in at 8:08 becomes 8:15. Payroll teams use it because shorter, cleaner numbers are easier to convert to decimal hours and multiply by a wage.
Rounding is a convenience, not a way to trim payroll. The Department of Labor allows it only because, done properly, the minutes rounded away on some punches are given back on others. If a policy only ever rounds in the employer’s favor, it breaks federal law.
The three allowed rounding increments
The federal rule names three increments. Each one has a midpoint: punches before it round down and punches at or after it round up.
| Increment | Rounds down | Rounds up | Example |
|---|---|---|---|
| Nearest 5 minutes | 0 to 2 minutes past | 3 to 4 minutes past | 8:02 → 8:00, 8:03 → 8:05 |
| Tenth of an hour (6 minutes) | 0 to 2 minutes past | 3 to 5 minutes past | 8:02 → 8:00, 8:04 → 8:06 |
| Quarter hour (15 minutes) | 0 to 7 minutes past | 8 to 14 minutes past | 8:07 → 8:00, 8:08 → 8:15 |
Tenth-of-an-hour rounding is popular with payroll teams because each increment is exactly 0.1 decimal hours. A 6-minute block is 0.1, a 12-minute block is 0.2, and so on, so rounded punches convert straight into decimal hours with no long fractions.
Try it: round any punch
Rounds to the nearest increment, the method federal rules allow when it averages out.

The 7-minute rule explained
The 7-minute rule is simply quarter-hour rounding written out. Every quarter hour is split at the halfway point, 7.5 minutes. Because punches are recorded in whole minutes, 7 minutes or less rounds back to the previous quarter hour and 8 minutes or more rounds forward.
| Actual punch | Rounded punch | Minutes gained or lost |
|---|---|---|
| 8:00 | 8:00 | 0 |
| 8:04 | 8:00 | −4 |
| 8:07 | 8:00 | −7 |
| 8:08 | 8:15 | +7 |
| 8:11 | 8:15 | +4 |
| 8:14 | 8:15 | +1 |
Over a large number of random punches, the ups and downs cancel out. That neutral outcome is what makes the policy lawful. The same logic applies at the end of a shift: a clock-out at 5:07 PM rounds to 5:00 PM, a clock-out at 5:08 PM rounds to 5:15 PM.
When rounding becomes illegal
A rounding policy is unlawful when, in practice, it consistently underpays. The DOL and the courts look at the result over time, not just the written policy. These patterns are the usual problems:
- Rounding only one way. Clock-ins always rounded forward and clock-outs always rounded back.
- Early punch restrictions plus rounding. Employees are required to be working at 7:55 but the clock rounds that punch to 8:00 every day.
- Rounding meal breaks. A 27-minute lunch recorded as 30 minutes can create missed meal break claims in states with meal period rules.
- Work before or after the punch. Logging in to systems, safety briefings or closing tasks that happen off the clock are work time regardless of rounding.
Example: a policy that never averages out
- An employee must be at the workstation by 7:53 AM, usually clocks out at 5:07 PM and takes a 1-hour unpaid lunch.
- Quarter-hour rounding records 8:00 and 5:00, so 8 hours are paid.
- Actual work time is 9 hours 14 minutes minus the lunch hour, which is 8 hours 14 minutes. 14 minutes are lost every day, and over five days that is 70 minutes (1.1667 hours). At $22 per hour, 1.1667 × $22 = $25.67 short every week.
- Because this employee’s punches never round in their favor, the policy is not averaging out for them and back pay may be owed.
Result: 70 minutes, $25.67 unpaid per week
State rules to check
Federal law sets the floor. Some states add stricter wage and hour rules that affect rounding, especially around meal periods.
| State | What to know |
|---|---|
| California | Neutral rounding was accepted in See’s Candy Shops v. Superior Court (2012), but Donohue v. AMN Services (2021) barred rounding of meal period punches. The California Supreme Court has also reviewed rounding in Camp v. Home Depot, so many California employers now pay to the exact minute. |
| States with daily overtime | Alaska, California, Colorado and Nevada can require overtime based on daily hours, so a few rounded minutes can move a shift over a daily threshold. |
| All states | Rounding never changes the obligation to pay minimum wage and overtime for all hours actually worked. |
Tip: Most modern time clock software can record the exact minute. When in doubt, paying to the minute removes the rounding risk entirely.
Rounding in Excel and Google Sheets
If you keep punches as times in a spreadsheet, these formulas round them to the nearest increment. The result is still a time, so format the cell as Time.
// Nearest quarter hour (time in A2)
=MROUND(A2,"0:15")
// Nearest tenth of an hour
=MROUND(A2,"0:06")
// Nearest 5 minutes
=MROUND(A2,"0:05")
// Rounded hours between two punches, as decimal hours
=(MROUND(B2,"0:15")-MROUND(A2,"0:15"))*24To total a week of shifts with breaks, the hours worked calculator does the same arithmetic and shows each step.
How to write a fair rounding policy
- Pick one increment and apply it to every punch, in and out.
- Round to the nearest increment, never always up or always down.
- Keep meal breaks exact where state law regulates meal periods.
- Audit a sample of timecards each quarter: compare rounded hours with exact hours. If the total consistently favors the employer, switch to exact-minute pay.
- Write it down in the handbook and apply it consistently.
Frequently asked questions
What is the 7-minute rule?
It is quarter-hour rounding. A punch 1 to 7 minutes past a quarter hour rounds down to it, and a punch 8 to 14 minutes past rounds up to the next quarter hour. 8:07 becomes 8:00 and 8:08 becomes 8:15.
Is time clock rounding legal?
Yes, under federal law, when employers round to the nearest 5 minutes, 6 minutes or 15 minutes and the policy averages out so employees are paid for all the time they actually work (29 CFR 785.48(b)). Some states are stricter.
Can an employer always round down?
No. A policy that only rounds in the employer’s favor does not average out and can lead to unpaid wage claims.
Is rounding to the nearest 6 minutes allowed?
Yes. The tenth-of-an-hour increment is 6 minutes, and each block equals 0.1 decimal hours, which makes payroll arithmetic simple.
Does rounding apply to breaks?
Federal law treats short rest breaks of 5 to 20 minutes as paid time. Meal periods of 30 minutes or more can be unpaid if the employee is fully relieved of duty. In California, meal period punches should not be rounded.
How do I round time in Excel?
Use =MROUND(A2,”0:15″) for quarter hours, “0:06” for tenths or “0:05” for 5 minutes, and format the result as Time.
