Time Card Rounding Rules Explained

Understanding 15-minute, quarter-hour, and 6-minute rounding rules. What employers can and cannot do with time card rounding.

What is time card rounding?

Time card rounding is the practice of rounding clock-in and clock-out times to a set increment, such as the nearest 5 minutes, 6 minutes, 10 minutes or 15 minutes. It is common in workplaces that use time clocks or payroll systems with fixed increments.

Common rounding increments

Common increments include nearest 5 minutes, nearest 6 minutes, nearest 10 minutes and nearest 15 minutes. Quarter-hour rounding is one of the most familiar methods because each hour is divided into four 15-minute blocks.

Neutral rounding matters

Rounding should not systematically undercount employee time. DOL guidance recognizes rounding practices such as nearest 5 minutes, one-tenth of an hour or quarter-hour rounding in some situations, but major discrepancies can raise concerns. A practice that always rounds down may create wage and overtime problems.

Example of quarter-hour rounding

With nearest 15-minute rounding, 8:07 may round to 8:00, while 8:08 may round to 8:15. The exact rule depends on the employer’s policy and payroll system. The important point is that the rule should be applied consistently and neutrally.

Rounding vs actual hours worked

Employees should still keep accurate records of actual start and stop times. If rounded totals regularly reduce paid time, workers and employers should review the policy and compare it against applicable wage and hour requirements.

Best practices for time card rounding

Use a written policy, apply the same rule consistently, avoid always rounding against employees, audit time records regularly, and keep original clock data when possible. For small businesses, exact minute tracking may be simpler than maintaining a rounding policy.
