FLSA Compliance: Understanding the 7-Minute Payroll Rounding Rule
In the United States, employer timekeeping is governed by the Fair Labor Standards Act (FLSA) under Department of Labor regulation 29 CFR § 785.48(b). The regulation permits employers to round employee starting and stopping times to the nearest 5 minutes, one-tenth of an hour (6 minutes), or quarter of an hour (15 minutes), provided it is done impartially.
The 7-Minute Rule Interval Table (15-Minute Quarter Hour)
When rounding to 15-minute increments, check which 7-minute boundary the minutes fall into:
08 - 14 Minutes → Round up to :15 (.25 hrs)
16 - 22 Minutes → Round down to :15 (.25 hrs)
23 - 29 Minutes → Round up to :30 (.50 hrs)
31 - 37 Minutes → Round down to :30 (.50 hrs)
38 - 44 Minutes → Round up to :45 (.75 hrs)
46 - 52 Minutes → Round down to :45 (.75 hrs)
53 - 59 Minutes → Round up to next hour (1.00 hr)
Why Decimal Hours Are Required for Payroll Software
Standard time clocks record hours and minutes using base-60 (sexagesimal) numbering. However, accounting and payroll software calculate employee compensation using base-10 (decimal) currency multiplication. If an employee earns $20.00/hour and works 40 hours and 30 minutes, you cannot multiply 40.30 × $20 (which would yield an incorrect $806.00). You must convert 30 minutes to 0.50 decimal hours: 40.50 × $20.00 = $810.00.
Frequently Asked Timecard Questions
No. Rounding is completely optional. Employers are permitted to pay employees for the exact minute worked. However, if an employer chooses to round time, it must be neutral and cannot consistently round in the employer's favor to shave employee compensation.
Under federal FLSA rules, non-exempt employees must receive overtime pay for all hours worked over 40 in a workweek at a rate not less than time-and-one-half (1.5×) their regular rate of pay. Some states (like California) also mandate daily overtime for hours over 8 in a single workday.
The 6-minute rule divides one hour into 10 tenths (0.1 hours = 6 minutes). This method is widely favored by law firms, accounting practices, and consulting agencies because it provides straightforward decimal addition (e.g. 18 minutes = 0.3 hours) with fewer rounding disputes.
