How Time Clock Rounding Works
Time clock rounding replaces your exact punch times with the nearest increment to simplify payroll math. Under federal law (29 CFR 785.48), employers can round to the nearest 5 minutes, 6 minutes (1/10 hour), or 15 minutes (1/4 hour). Each clock-in and clock-out gets rounded separately, not the total hours worked.
The "7-minute rule" is just 15-minute rounding by another name. If you're 1-7 minutes past a quarter hour, it rounds down. If you're 8-14 minutes past, it rounds up. The practice goes back to manual time cards, when calculating exact minutes for every employee was a headache nobody wanted.
FLSA rules and legal requirements
The Fair Labor Standards Act allows rounding, but there's a catch: it has to be neutral over time. If an employer always rounds clock-in times up and clock-out times down, that's an FLSA violation because it chips away at paid hours every single shift. The rule covers non-exempt (hourly) employees, and some states go further. California courts, for example, have required employers to prove their rounding policy is actually neutral in practice, not just on paper.
The real cost of rounding
A few minutes a day might not feel like much. But lose 5 minutes every shift at $20/hour and that's about $433 gone by the end of the year. Keep records of your actual punch times so you can spot whether rounding is consistently working against you.
| Daily Loss | Weekly Loss | Annual Hours | Annual Pay ($20/hr) |

| 1 min | 5 min | 4.3 hrs | $86.67 |
| 3 min | 15 min | 13.0 hrs | $260.00 |

15-minute (quarter-hour) rounding reference
This is the most common rounding method. It's where the 7-minute rule comes from.
| Clock Time | Rounds To | Decimal | Direction |
|---|---|---|---|
| :00 - :07 | :00 | .00 | Down |
| :08 - :14 | :15 | .25 | Up |
| :15 - :22 | :15 | .25 | Down |
| :23 - :29 | :30 | .50 | Up |
| :30 - :37 | :30 | .50 | Down |

| :45 - :52 | :45 | .75 | Down |
| :53 - :59 | :00 (+1hr) | .00 | Up |
6-minute (tenth-hour) rounding reference
Payroll departments like this one because each increment is exactly 0.1 hours, so decimal conversion is trivial.

| :03 - :08 | :06 | .1 |

Frequently Asked Questions
Common questions about time clock rounding and the 7-minute rule
What is the 7-minute rule for time clocks?
The 7-minute rule is the FLSA-permitted practice of rounding employee time to the nearest 15-minute (quarter-hour) increment. If your punch falls 1-7 minutes past a quarter hour, it rounds down. If it's 8-14 minutes past, it rounds up. So clocking in at 8:07 rounds to 8:00, but clocking in at 8:08 rounds to 8:15.
Is time clock rounding legal?
Yes, under federal law (29 CFR 785.48). Employers can round to the nearest 5 minutes, 6 minutes (1/10 hour), or 15 minutes (1/4 hour). The catch is that rounding has to be neutral over time and can't systematically favor the employer. Some states have tighter restrictions on top of the federal rule.
How does 6-minute (1/10 hour) rounding work?
Six-minute rounding splits each hour into ten 6-minute segments. The breakpoint sits at 3 minutes within each segment. Clocking in at 8:02 rounds to 8:00 (within 3 minutes of :00), but clocking in at 8:04 rounds to 8:06 (past the midpoint). Payroll departments favor this method because each increment converts to a clean 0.1 hours.
Does rounding apply to total hours or individual punches?
It's applied to each clock-in and clock-out time individually, not to total hours worked. That matters because rounding 8 hours and 7 minutes of total work down to 8 hours is not the same thing as rounding each punch separately. The FLSA says rounding applies to "starting time and stopping time."
Can my employer always round down?
No. Federal law says rounding has to be applied neutrally. If an employer rounds clock-in times up and clock-out times down every shift, they're violating the FLSA because it systematically cuts paid hours. Over time, the rounding has to average out so employees are fully compensated.
How much money can rounding cost me per year?
Small daily differences add up fast. Losing 5 minutes per day at $20/hour works out to about $433 per year (5 min x 5 days x 52 weeks / 60 min x $20). At $30/hour, that same 5-minute daily loss is roughly $650. Plug your own numbers into the calculator above to see your exact figure.
What states have special time clock rounding rules?
A handful of states go beyond the federal rules. California courts have required employers to show that their rounding policy is neutral in practice, not just in theory. Alaska, Colorado, and Nevada each have their own specific regulations too. Check with your state's labor department for the details that apply to you.
What is the difference between 5-minute, 6-minute, and 15-minute rounding?
The interval controls how much each punch can shift. 5-minute rounding (breakpoint at 2.5 min) moves your time the least per punch. 6-minute rounding (breakpoint at 3 min) divides hours into clean tenths, which is why payroll software likes it. 15-minute rounding (breakpoint at 7.5 min, the "7-minute rule") can shift a punch the most but is still the most common in traditional payroll systems.
