Minutes to decimal hours chart
Payroll systems want decimal hours, not clock time. The rule is one division: a minute is one sixtieth of an hour, so divide the minutes by 60 — 15 minutes is 0.25, 30 minutes is 0.5, 45 minutes is 0.75.
Minutes to decimal hours, 0–90 minutes

| 30 | 0.50 | ||
| 75 | 1.25 | ||
| 35 | 0.58 | ||

The formula
Decimal hours = hours + (minutes ÷ 60). Seven hours and 32 minutes is 7 + 32/60 = 7.5333 — payroll typically bills that as 7.53. Going the other way, multiply the decimal part by 60: 7.53 − 7 = 0.53 × 60 ≈ 32 minutes.
Common payroll conversions
| Time | Decimal |
|---|---|
| 1 min | 0.02 |
| 6 min | 0.10 |
| 7 min | 0.12 |
| 8 min | 0.13 |
| 10 min | 0.17 |
| 15 min | 0.25 |
| 20 min | 0.33 |
| 30 min | 0.50 |
| 45 min | 0.75 |
| 60 min | 1.00 |
Rounding before converting
Some employers round punches first (nearest 5, 6, 10 or 15 minutes) and only then convert — see time clock rounding rules for when that is allowed. To see both at once, enter your punches in the calculator and switch the hours format between decimal and hours:minutes; the bi-weekly case is covered in the bi-weekly timesheet guide.
