The 7-Minute Rule and Quarter-Hour Time Clock Rounding, With Chart (2026)

Here's how rounding works, the chart, where it goes wrong, and an honest look at whether you should be rounding at all.

01

What the 7-minute rule says

Federal regulations at 29 CFR 785.48(b) allow employers to round punch times to the nearest 5 minutes, 6 minutes (tenth of an hour), or 15 minutes (quarter hour). Quarter-hour rounding is where the famous 7-minute split comes from: within a 15-minute block, the first 7 minutes round down and the last 8 round up.

So on quarter-hour rounding, a 7:07 clock-in becomes 7:00, and a 7:08 clock-in becomes 7:15. The same split applies on the way out: a 3:37 clock-out becomes 3:30, and a 3:38 becomes 3:45.

02

The quarter-hour rounding chart

For a punch near the hour, quarter-hour rounding works like this. The same pattern repeats for every quarter of every hour.

Tenth-of-an-hour rounding uses 6-minute blocks with a 3-minute split, which produces smaller swings per punch and is common in payroll systems that compute in decimal hours.

03

The one condition everything hangs on

Rounding is legal under the federal rule only if it's neutral, meaning it averages out over time and doesn't systematically shortchange workers. Round down and round up with the same arithmetic, applied to everyone, in both directions.

The pattern that gets employers sued is one-directional rounding in practice, even when the written policy looks neutral. Two common ways that happens:

1. Behavior is not symmetric. Workers who are told not to clock in early will punch at 6:58 to 7:06, and quarter-hour rounding converts nearly all of that to 7:00. Meanwhile clock-outs cluster right after the quarter mark. The policy is neutral on paper and the outcomes are not, and outcomes are what get audited.
2. Rounding stacks on a grace period. A rule like "we round, and also anything within 5 minutes of shift start counts as on time" tends to double-shave the same edge of the shift.

If a review of a few months of punches shows workers losing minutes on average, the rounding isn't neutral, whatever the handbook says.

04

Rounding and grace periods are different things

A grace period is a scheduling forgiveness: clock in at 7:04 for a 7:00 shift and you're not written up. Rounding is a pay calculation. Mixing the vocabulary leads crews to believe minutes are being stolen, and leads owners to believe discipline policy is pay policy. Keep them separate in writing: pay comes from the punch record and the rounding rule; lateness is handled as a conduct matter.

05

Do you even need rounding anymore

Rounding exists because 1960s punch cards were added up by hand, and quarter hours made the arithmetic humane. A digital punch does its own arithmetic. When the timesheet adds itself up, rounding no longer saves any work; the only thing it changes is who wins the edge minutes, and that's exactly the part that creates legal exposure.

Paying to the exact minute is the option with nothing to defend. No neutrality analysis, no chart taped to the wall, no argument at 7:08. Several states' courts have signaled the same direction, treating rounding as increasingly hard to justify when the employer demonstrably has exact records. The California Supreme Court has Camp v. Home Depot under review as of August 2026, and the question in that case is whether rounding survives there at all. If you have exact punches and you round them anyway, you're choosing a fight you don't need.

The honest exceptions: if your payroll provider requires quarter-hour increments, or a union agreement specifies rounding, then run a genuinely neutral rule and audit it now and then.

How Clox handles it

Clox records the exact minute of every punch, and the overtime and break engine computes totals from those exact times, so the default is the clean case: what the worker punched is what payroll pays. If you do apply a rounding policy, it's applied consistently in the calculation rather than by a foreman's pencil, and the totals you approve on Friday match the payroll export to the minute. The punch record itself stays intact underneath, signed and hash-chained, so if a dispute ever reaches an audit you can produce the original times, not just the rounded results. You can see how the record works or read up on what to have ready for a workers' comp audit.

07

The short version

Quarter-hour rounding with the 7-minute split is still legal federally when it's truly neutral in outcomes, not just on paper. But it earns you nothing once punches are digital, some states are hostile to it, and the failure mode is a back-pay claim with your name on it. Record exact minutes, pay exact minutes, and spend the argument budget somewhere else.
