Time clock rounding calculator
Many time clocks round punches to the nearest quarter hour, the so-called 7-minute rule. Enter your actual in and out times for the week, choose the rounding your employer uses, and the calculator shows the rounded punches, the minutes you gained or lost each day, and what that adds up to over a year at your hourly rate. If every day rounds against you, it says so.
How to use this calculator
- Pick the rounding rule your time clock uses. Nearest 15 minutes is the 7-minute rule; nearest 6 minutes is tenths of an hour.
- Enter your actual clock-in and clock-out times for each day, from your own record or the raw punches on the time clock.
- Enter your hourly rate and how many weeks a year look like this one.
- Read each day: the rounded times and the minutes gained or lost. Red is time you worked but were not paid for.
- Check the totals bar for the week and the year. If every day is red, the rounding is one-sided.
What the 7-minute rule is
Under 29 CFR 785.48(b), employers may round starting and stopping times to the nearest 5 minutes, tenth of an hour or quarter hour. With quarter-hour rounding, a punch from 7:53 to 8:07 becomes 8:00, and 8:08 becomes 8:15: 7 minutes either side of the quarter hour, which is where the name comes from.
The regulation allows this only on the assumption that the rounding averages out, so that over time employees are paid for all the time they actually work. Rounding that consistently favours the employer, or that rounds clock-in up and clock-out down, is not the practice the regulation describes.
How rounding costs money
A worker who clocks in at 7:53 and out at 4:07 every day is paid 8:00 to 4:00: 14 minutes a day, 70 minutes a week, about 58 hours a year. At $18 an hour that is roughly $1,050 a year. The same worker clocking in at 8:07 and out at 3:53 gains the same amount. The calculator shows both directions; what matters is the pattern over weeks.
Some employers pair rounding with a grace period, say 5 minutes, which is a separate policy and is not the same as rounding. Other systems round only the shift total rather than each punch, which produces smaller differences. Enter your actual punches and compare with the hours on your pay stub to see which your employer does.
What to do with the numbers
Keep your own record of actual punches, not just the rounded figures the system shows you. Employers are required to keep accurate records of hours worked (29 CFR 516.2), and a dispute over rounding is decided on whether the practice paid you for all hours over time. A week of your own times next to the rounded times is the evidence that question needs. The PunchStamp app keeps that record automatically and shows actual against rounded for every shift.
Frequently asked questions
Is the 7-minute rule legal?
Yes, under 29 CFR 785.48(b), as long as the rounding does not, over a period of time, fail to pay employees for all the time they actually worked. Rounding that is consistently in the employer's favour does not meet that condition.
How does the 7-minute rule work?
Punches are rounded to the nearest quarter hour. 7 minutes or less past the quarter hour rounds down; 8 minutes or more rounds up. 8:07 becomes 8:00 and 8:08 becomes 8:15. The same applies at clock-out.
Can my employer round my clock-in up and my clock-out down?
Rounding has to be neutral. A system that always rounds in the employer's favour is not the practice the regulation permits. Record your actual times and compare them with your pay stub; this calculator does the comparison.
What is rounding to the tenth of an hour?
Punches round to the nearest 6 minutes, giving hours like 8.1 or 7.9 on the pay stub. Choose nearest 6 minutes in the calculator to model it.
Does rounding apply to breaks?
It can, if breaks are punched. Short rest breaks of 5 to 20 minutes must be paid under 29 CFR 785.18 regardless of rounding, and rounding a 30-minute unpaid meal to 45 minutes deducted would underpay you.
How much can rounding cost per year?
It depends on your punch pattern. Losing 14 minutes a day, five days a week, for 52 weeks is about 60 hours. Enter your rate above to see the dollar figure for your own pattern.
Can I recover pay lost to unfair rounding?
Unpaid wages under the FLSA can generally be claimed for two years, three if the violation was wilful (29 U.S.C. 255). Your own record of actual punches is the starting point. Talk to your state labor department or the U.S. Department of Labor Wage and Hour Division.
