Time Clock Rounding Calculator
See how the 7-minute rule and 5, 6, 10, or 15-minute rounding change your paid hours, and what a week of rounded punches costs you over a year.
Time Clock Rounding Calculator
Enter your real punches for the week and see exactly how many minutes the rounding rule takes back, and what those minutes are worth over a year.
Your Punches This Week
Enter the times your clock actually recorded, to the minute, not the rounded times on your pay stub. Leave a day blank if you didn't work it. If clock-out is earlier than clock-in, the shift is treated as crossing midnight.
Punching out for an unpaid lunch? That break has its own pair of punches. Enter those punches as their own row, or net the break out first with the timesheet calculator.
Rounding Increment
15 minutes is the quarter-hour rule most time clocks use, and that is where the 7-minute rule comes from.
Rounding Rule
Nearest is the standard, and the only one that can average out. Always-down and always-up apply to both punches, so part of the effect cancels.
Hourly Rate
Used only to price the minutes. Ignore it if you only want the hours.
Nearest 15 minutes: the 7-minute rule
Gross hours and gross dollars only. The annual figure is 52 weeks of the same schedule, so it shows the size of the swing rather than predicting your year.
Your week crosses 40 hours, and rounding can move the overtime line as well as the regular hours. Price the premium with the overtime calculator or the time and a half calculator.
The federal standard
"It has been found that in some industries, particularly where time clocks are used, there has been the practice for many years of recording the employees' starting time and stopping time to the nearest 5 minutes, or to the nearest one-tenth or quarter of an hour. … this practice of computing working time [will be accepted] provided that it is used in such a manner that it will not result, over a period of time, in failure to compensate the employees properly for all the time they have actually worked."
29 CFR 785.48(b)
Keep Your Own Punch Record
ClockWage44 records your shifts to the minute across as many jobs as you want and totals them on-device, so you always have your own record to hold a rounded stub against.
How time clock rounding actually works
Rounding happens punch by punch, not to your daily total. Your clock-in gets pulled to the nearest mark on the grid, your clock-out gets pulled to the nearest mark, and your paid time for the day is the gap between the two rounded values. That is the practice 29 CFR 785.48(b) describes: recording starting time and stopping time to the nearest increment.
Take the shift this page loads with. You clock in at 8:58 and out at 5:04, which is 8 hours and 6 minutes, or 8.10 hours. At the quarter hour, 8:58 rounds forward to 9:00 and 5:04 rounds back to 5:00. Paid time is exactly 8.00 hours. Six minutes disappeared, and both ends of the shift contributed: two minutes at the start, four at the end. Five days of that is half an hour a week.
At a 15-minute increment, the grid looks like this:
| Punch falls between | You are paid from |
|---|---|
| :53 to :07 | :00 |
| :08 to :22 | :15 |
| :23 to :37 | :30 |
| :38 to :52 | :45 |
That table is the 7-minute rule. Seven minutes past a quarter mark rounds back, eight minutes past rounds forward, and the furthest any single punch can travel is 7 minutes. Tenth-of-an-hour rounding uses the same idea on a tighter grid: marks every 6 minutes at :00, :06, :12, :18 and so on, with a maximum move of 3 minutes. Five-minute rounding caps the move at two and a half minutes.
Because both punches move independently, a single day can gain and lose at the same time. It also means very short work can vanish. Clock in at 9:02 and out at 9:05 with quarter-hour rounding and both punches land on 9:00, so a 3-minute stretch of work pays 0.00 hours. Try it in the grid above.
One thing this tool leaves out on purpose: unpaid break columns. In most real systems a lunch break is its own pair of punches, and it gets rounded the same way your shift punches do. Run those punches as their own row, or use the timesheet calculator to net breaks out of the week first.
What the FLSA allows, and where the law is heading
The federal baseline is 29 CFR 785.48(b). It lets employers record starting and stopping times to the nearest 5 minutes, the nearest tenth of an hour, or the nearest quarter hour, but the permission comes with a condition: the practice cannot, over a period of time, fail to compensate employees for all the time they have actually worked. Neutrality is the whole test.
The Department of Labor spelled that out in opinion letter FLSA2019-9 (July 2019) with two questions. Is the rounding policy neutral on its face? And does it average out so employees are fully paid for the time they actually work? An employer that can answer yes to both is compliant.
Courts read it the same way. In Corbin v. Time Warner Entertainment-Advance/Newhouse Partnership, 821 F.3d 1069 (9th Cir. 2016), the Ninth Circuit upheld nearest-quarter-hour rounding even though the plaintiff came out $15.02 behind over a year. The part people miss: an individual employee doesn't have to break even. The policy has to be neutral on its face and neutral as applied, in the aggregate, over time.
California is where the ground is moving. In Donohue v. AMN Services, LLC (2021) 11 Cal.5th 58, the California Supreme Court held that employers may not round meal-period punches at all, even neutrally, because the 30-minute meal period is a bright-line entitlement rather than an average. Donohue was narrow on purpose. It decided meal periods and expressly left the general rounding question open.
That open question is Camp v. Home Depot U.S.A., Inc. In October 2022 the California Court of Appeal, Sixth District, held that where an employer captures the exact time an employee worked, it must pay for all of that time; Home Depot had recorded punches to the minute and then rounded each day's total worktime to the nearest quarter hour. The California Supreme Court granted review on February 1, 2023 (No. S277518), which under California practice removed the appellate opinion as binding authority. Briefing finished in 2023. As of 2026 the case has still not been argued and no opinion has issued, and it is now the oldest unargued civil case on the court's docket. Treat the 2022 appellate reasoning as the direction of travel, not as settled statewide law, and be skeptical of any article that tells you the California Supreme Court has ruled on rounding. Several page-one results say exactly that, and it has not happened.
Rounding was invented because manual timecards were painful to total by hand. Systems that capture punches to the second have made that justification thin, and both regulators and courts have noticed.
When rounding stops being neutral
The distinction that matters to you is not size, it is direction. Random variation is what neutral rounding looks like from the inside: 9 minutes in your favor Monday, 6 against you Tuesday, roughly even across a month. That is the system working as 785.48(b) intends.
A systematic direction is different. The clearest example is rounding the clock-in up and the clock-out down, so every shift loses minutes and none ever gains. That is a one-way ratchet, it can never average out, and averaging out is the express condition in the regulation. Grace periods that only apply against you, or a requirement that you be on the floor working before your rounded start time, do the same thing by another route.
Notice what the always-down and always-up settings above do, because they surprise people. Flooring both punches hands you free minutes at the start of the shift and takes them back at the end, so most of the effect cancels and the weekly number stays small. On the default 8:58 to 5:04 shift, always-down and always-up each gain 9 minutes while nearest loses 6. The chip describes which way the punches move, not who comes out ahead.
What to do with a week that lands against you: keep your own punch record, compare it against the stub, and remember that 785.48(b) is written about what happens "over a period of time." One week is a data point, not proof. If the pattern holds across a month or a quarter and always runs one direction, that is the situation the regulation is aimed at, and your state labor agency or the DOL Wage and Hour Division is where complaints go.
One more wrinkle worth knowing: it is usually your rounded hours, not your actual hours, that cross the 40-hour line. Rounding can push you into overtime or pull you out of it. This page stops at gross hours and gross dollars, so take the rounded weekly figure over to the overtime calculator to price what happens past 40.
This calculator gives estimates only, based on the punch times and rounding rule you enter, and it is not tax, legal, or payroll advice. State law can be stricter than the federal rule. Check your own pay stub and time records, and talk to your state labor agency or an employment attorney about a specific situation.
Frequently Asked Questions
Common questions about time clock rounding calculator
What is the 7-minute rule for time clocks?
It is what nearest-quarter-hour rounding looks like from the employee's side. Every punch gets pulled to the closest :00, :15, :30, or :45. If you're within 7 minutes past a quarter mark, your punch drops back to it; at 8 minutes or more it jumps forward to the next one. Clock in at 8:07 and you're paid from 8:00; clock in at 8:08 and you're paid from 8:15. The same test runs on your clock-out, which is why the rule can pay you for time you didn't work as easily as it can shave time you did.
Is time clock rounding legal?
Under federal law, yes, with conditions. 29 CFR 785.48(b) permits rounding starting and stopping times to the nearest 5 minutes, tenth of an hour, or quarter hour, but only if the practice does not, over a period of time, fail to pay employees for all the time they actually worked. The Ninth Circuit applied that standard in Corbin v. Time Warner (2016) and upheld quarter-hour rounding even though the employee finished the year $15.02 short. The Labor Department's 2019 opinion letter FLSA2019-9 used a two-part test: the policy has to be neutral on its face, and it has to average out in practice. State law can be stricter.
Can my employer always round down?
No. A policy that only ever moves time in the employer's direction cannot average out, which is exactly what 785.48(b) requires. The clearest version of the problem is rounding your clock-in up and your clock-out down: every shift loses minutes and none ever gains. But "always round down on both punches" is a different animal, because flooring your clock-in hands you free minutes at the start of the shift and takes them back at the end, so the two partly cancel. Try both settings above and watch the weekly total move.
Does rounding apply to each punch or to my total hours?
This calculator rounds each punch, which is the practice 785.48(b) actually describes. Some employers instead add up the exact minutes and round the daily or weekly total. The two produce different answers, and total-hours rounding is what was challenged in Camp v. Home Depot: the company recorded punches to the minute but rounded each day's total to the nearest quarter hour. If your employer rounds totals, compare your exact daily minutes against your pay stub rather than using the rounded punches here, and the timesheet calculator will give you the unrounded weekly figure.
Is rounding still allowed in California?
Partly, and the rest is unresolved. In Donohue v. AMN Services (2021) the California Supreme Court held that meal-period punches cannot be rounded at all, even neutrally, because the 30-minute break is a bright line. For ordinary shift punches, a California Court of Appeal held in 2022 in Camp v. Home Depot that an employer that captures exact time must pay for exact time. The California Supreme Court granted review in February 2023, and as of 2026 the case has still not been argued or decided. Until it is, California rounding sits in open territory, and a lot of what you'll read online wrongly reports it as settled.
How much can rounding actually cost me in a year?
Six minutes a day is the number worth remembering, because it is what an 8:58 to 5:04 shift loses to quarter-hour rounding. That is half an hour a week, roughly 26 hours a year, and at $20 an hour about $520. The direction matters more than the size: a policy that lands against you every single day is the pattern 785.48(b) is aimed at, while a policy that gives you 9 minutes one day and takes 6 the next is doing what it's supposed to do.
What is the difference between 5, 6, 10, and 15-minute rounding?
It is how far any single punch can move. Six-minute rounding, also called tenth-of-an-hour, shifts a punch by at most 3 minutes and lines up neatly with decimal payroll (0.1, 0.2, and 0.3 of an hour), which the decimal hours converter shows in detail. Five-minute rounding moves a punch by at most two and a half minutes. Fifteen-minute rounding can move it a full 7 minutes in either direction, which is why it produces the biggest swings. The regulation names 5 minutes, one-tenth of an hour, and one-quarter hour; 10-minute rounding is common in the field but isn't one of the three it lists.
My pay stub hours do not match my punches. What should I do?
Start by getting your own record. Write down your actual punch times for a full pay period and run them through this tool with the increment your employer uses, then compare against the stub. If the stub is lower than both your actual hours and the rounded hours, the gap isn't rounding and something else is going on. The hours and minutes calculator helps you add the differences up by hand. Under the FLSA your employer has to keep accurate time records, and you're entitled to see yours. Your state labor agency or the DOL Wage and Hour Division takes complaints, and several states give you a right to copies of your own time records on request.
