How Payroll Decimal Conversion Works

When an employee clocks in at 8:07 AM and out at 4:52 PM, the total time worked is 8 hours 45 minutes. Payroll systems need this as 8.75 decimal hours to calculate gross pay.

8 hours 45 minutes → 8 + (45 ÷ 60) = 8.75

At $22/hour: 8.75 × $22 = $192.50 gross pay for the shift.

Payroll-Specific Considerations

Rounding Rules

Under FLSA, employers may round to the nearest 5, 6, or 15 minutes as long as it averages out fairly. The 7-minute rule is most common: 1–7 min rounds down, 8+ rounds up.

Break Deductions

Subtract unpaid break time before converting. If an 8.5-hour shift includes a 30-minute unpaid lunch, the payable time is 8.00 hours.

Overtime Tracking

FLSA requires overtime at 1.5× for hours over 40 per week. Decimal format makes weekly totals easy to sum: 8.75 + 8.50 + 9.00 + 8.25 + 8.50 = 43.00 total (3.00 OT).

Frequently Asked Questions

Why does payroll need decimal hours?\u25BE
Payroll software multiplies hours by the pay rate. Decimal format (7.75 instead of 7:45) allows direct multiplication: 7.75 × $20 = $155.00.
How many decimal places should I use for payroll?\u25BE
Two decimal places is standard for most payroll systems. This gives accuracy to the nearest 0.6 minutes (36 seconds), which is more than sufficient.
Should I round employee time?\u25BE
Rounding is permitted under FLSA if it averages out fairly. The most common practice rounds to the nearest 15 minutes using the 7-minute rule.
How do I handle overnight shifts?\u25BE
If an employee works 10 PM to 6 AM (8 hours), you can calculate total hours by adding 24 to the end time: (6+24) - 22 = 8.00 hours.
