Time clock rounding and the seven minute rule, explained properly

What rounding is, and where the rule comes from

Rounding means paying to a fixed grid of time rather than to the exact minute. An employee clocks in at 8:58 and clocks out at 5:06. Under quarter hour rounding they are paid from 9:00 to 5:00. The recorded times do not change. The paid times sit on the nearest mark.

The federal basis is 29 CFR 785.48, a regulation that dates to a period when time was recorded on a mechanical punch clock and payroll was worked out by hand on paper. Rounding existed because adding 1,400 exact minute figures by hand every fortnight was genuinely difficult. The regulation permits it in narrow terms. It names three intervals that have been accepted in the industry, five minutes, one tenth of an hour which is six minutes, and one quarter of an hour, and it attaches a condition that does all the work:

Read that twice, because almost every rounding mistake is a failure to take it literally. It is not a rule about the design of your policy. It is a rule about the outcome of your policy measured across time.

The seven minute rule is just a nickname

There is no seven minute rule in the regulation. What people are describing is the midpoint of a quarter hour. If you round to the nearest fifteen minutes, then the first seven minutes after a mark round back and the next eight round forward. Seven minutes is where the boundary falls.

Worked through, with a shift starting at 9:00:

• Clock in at 9:07 and you are paid from 9:00. Seven minutes in your favour.
• Clock in at 9:08 and you are paid from 9:15. Seven minutes in the employer’s.
• Clock out at 5:07 and you are paid to 5:00.
• Clock out at 5:08 and you are paid to 5:15.

Notice that we named the boundary minutes rather than saying something vague like “9:06 pays from 9:00”. If you are explaining this to staff, always give them the two minutes on either side of the line. “Anything up to 9:07 pays from 9:00, anything from 9:08 pays from 9:15” is a sentence somebody can check against their own timesheet. Any softer version invites the suspicion that the rule is being described loosely on purpose.

Over a large number of shifts with genuinely random arrival times, the gains and losses cancel. That balance is the entire justification for the practice. It is also the assumption that breaks in the real world, and that is what the last few years have been about.

Neutral has to mean neutral in practice, not on paper

Some timekeeping products will offer you rounding that always goes one way. Always round down on clock in, always round down on clock out, or round the start of a shift forward to the scheduled time. Every one of those is a wage violation waiting to be found, and a vendor offering it as a configuration option is selling you a liability with a checkbox.

Even genuinely neutral rounding stops being neutral when arrivals are not random, and in most workplaces they are not. People arrive a few minutes early because being late has a cost and being early does not. If your staff systematically clock in at 8:52 and clock out at 5:02, then neutral quarter hour rounding takes eight minutes off the front of every shift and gives two back at the end. The policy is symmetric. The outcome is not.

That is exactly what the Eighth Circuit looked at in Houston v. St. Luke’s Health System in August 2023. The employer rounded clock times within six minutes of the scheduled start or end of a shift to the scheduled time. The district court had granted the employer summary judgment. The Eighth Circuit vacated that and sent the case back, because the evidence showed the policy cost time for nearly two thirds of employees, and the employees who lost time lost more than their colleagues gained.

The court did not strike down the regulation, and it is worth being accurate about that since plenty of summaries say otherwise. What the decision establishes is narrower and more demanding: a rounding policy that looks balanced in its design can still fail the regulation on its results, and an employer who has never measured the results has no answer when somebody else measures them.

California is on a different track

In California a Court of Appeal held in Camp v. Home Depot that where an employer can capture and does capture the exact minutes worked, it must pay for all of them, regardless of whether its rounding is neutral. The California Supreme Court granted review in February 2023 and the case is still pending, which means the appeal court’s decision is not settled law and the question is genuinely open.

The reasoning is what matters for planning, though, and it is hard to argue with. The historical justification for rounding was administrative difficulty. A modern time clock records to the second and a computer adds the column instantly. If the exact figure is sitting in the database and you have chosen to pay a different one, the difficulty defence is gone.

So should you round at all?

Our own product defaults to exact minutes, and the default is a legal position rather than a design preference. But there are real reasons businesses round, and it is worth treating them seriously rather than waving them away.

Reasons that hold up

• Your payroll provider or union agreement requires a grid. Some do. If the agreement says quarter hours, that is the arrangement you are operating under.
• You genuinely cannot capture exact time. If shifts are recorded on paper and transcribed, you are rounding whether you call it that or not, and doing it on a stated rule is better than doing it by whoever is typing.
• Predictability for staff. Some employees prefer knowing that arriving at 8:55 and 8:58 pay identically. This is a real preference and it is worth respecting.

Reasons that do not

• It saves money. If rounding is saving you money it is not neutral, and you have written down the reason you will lose.
• It discourages early arrival. Rounding is not a scheduling control. If people are clocking in fifteen minutes early and you do not want them to, the answer is the schedule and the conversation, not the pay arithmetic.
• It is how we have always done it. Understandable, and not a defence.

If you do round, do it like this

Five rules. They are not complicated, and following them is most of the battle.

1. Nearest only. Never always up, never always down, never to the scheduled time. Only three intervals have accepted footing, five minutes, six minutes and fifteen minutes. Anything else is an invention.
2. Record the exact time regardless. The rounding applies to what is paid, never to what is recorded. The exact punch is the wage record, and you will want it the day somebody asks a question. Our engine works this way by construction: the recorded times are never touched and only the paid figure computes from the rounded boundaries.
3. Never round the same shift twice. If you deduct an unpaid meal break, rounding both the shift boundaries and the break deduction compounds the error. Our break deductions are always computed on exact measured time for this reason.
4. Measure the outcome. Once a quarter, total the rounded paid minutes against the exact recorded minutes for the whole workforce. If the number leans consistently in your favour, your policy is not neutral in practice whatever it says on paper. This is the single test that Houston turns on, and almost nobody runs it.
5. Tell people. Write the rule down with the boundary minutes named, put it where staff can read it, and say plainly that the exact times are recorded. A pay practice that staff discover for themselves reads as something that was being hidden, even when it is entirely lawful.

How to actually run the neutrality test

Rule four is the one nobody does, so here it is concretely. Export a quarter of punch data with the exact clock in and clock out times for every shift. In a spreadsheet, compute two columns: the exact minutes between each pair, and the minutes between the same pair after rounding each end to your interval. Subtract one from the other and total the difference across every shift.

A neutral policy produces a total near zero, drifting either way from quarter to quarter. If the total is consistently negative for the workforce, your policy is taking time. Look at the per employee figures as well as the total, because a total near zero can hide two groups moving in opposite directions, and the group losing time is the one that matters. Then look at the shape of the arrivals: if most people clock in six or seven minutes before the hour, that is the cause, and it is a scheduling pattern rather than a rounding fault.

The whole exercise is an hour of somebody’s time once a quarter. In Houston the plaintiff produced precisely this analysis and it was enough to reverse a summary judgment. An employer who runs it first knows what it says before anybody else does, and can fix a drifting policy while it is still a spreadsheet rather than a claim.

If you operate in California, read the last two again, and take advice before setting up rounding at all. The direction of travel there is clear even though the destination is not yet fixed.
