What this page sets up
The calculator opens with quarter-hour rounding on. Each punch is moved to the nearest quarter hour before the hours are added up, using the 7-minute rule: 1 to 7 minutes past rounds down, 8 to 14 rounds up. Every day shows the rounded hours with the punched hours next to them, and the results show both totals and the difference, so you can see exactly what rounding did to this card.
Enter your punches exactly as the time clock recorded them, not already rounded. The example card has five days of punches a few minutes either side of the hour. Punched, the week is 42 hours 14 minutes. Rounded, it’s 42:00, so this week the rounding cost the employee 14 minutes. Another week it might add time. That’s the test federal rules apply (29 CFR 785.48(b)): rounding must average out over time, not always favor the employer.
Checking a rounding policy
Keep a few weeks of your own punch times and enter each week here. If the paid total keeps coming out below the punched total, the rounding may not be neutral in practice, especially if you’re told to clock in no earlier than a set time but can clock out late. Save or print each week as a record: the PDF shows both the punched and the rounded times. Share result sends the week as a link: it shows the paid totals, and Open this card brings back the punched and rounded times.
Other increments
Some employers round to the nearest 5 or 6 minutes (a tenth of an hour) instead. Change the rounding setting and the card recalculates. With 6 minutes, a punch 3 minutes past rounds up.
