Why payroll uses decimal hours

Decimal hours make multiplication straightforward. If someone works 8 hours 15 minutes, the 15 minutes becomes 0.25 hours, so the time can be written as 8.25 hours before multiplying by an hourly wage. The same logic turns 8 hours 30 minutes into 8.50 and 8 hours 45 minutes into 8.75. The key is dividing minutes by 60 rather than treating minutes as hundredths.

Use the chart for quick checks

This table lists every minute from 0 through 59 rounded to two decimal places. It is useful for reviewing a payroll report, filling out a decimal timesheet, or checking whether a conversion was entered correctly. For exact calculations with larger hour totals, use the Decimal Hours Calculator, which converts in both directions and avoids manual rounding.
