Frequently Asked Questions
Why does payroll use decimal hours instead of hours and minutes?
Decimal hours multiply cleanly by an hourly rate — 7.5 hours × $20/hour = $150 exactly. Hours and minutes
(7h 30m) can't be multiplied directly without converting first.
Guide: understanding your result
Key points
- Decimal hours = hours + minutes ÷ 60. Payroll systems use decimal hours to multiply time by an hourly rate.
- Federal rules allow employers to round time to the nearest 5, 6 or 15 minutes only if rounding averages out and does not consistently underpay workers.
- 7 hours 45 minutes is 7.75 hours, not 7.45.
Worked example
7 h 45 min at $22/hour: 7 + 45 ÷ 60 = 7.75 hours → 7.75 × $22 = $170.50.
