Decimal Hours Calculator
A decimal hours calculator converts clock times into decimal hours — so 8 hours 15 minutes becomes 8.25 — which is the format most payroll systems expect.
Turn clock times into decimal hours without doing the division yourself. Enter your shifts and the decimal hours calculator returns the total payroll-ready, alongside the familiar hh:mm.
It's the same engine as our time card calculator, tuned to put decimal hours front and center.

How to use this calculator
- Enter start and end times for each day.
- Add any unpaid break minutes.
- Read the decimal-hours total — for example, 38.75 — next to the hh:mm total.
- Apply rounding if your payroll system expects it.
How overtime is handled
Regular and overtime hours are both shown in decimal form, ready to multiply by a pay rate. Choose the overtime rule that matches your job.
How breaks are handled
Break minutes are removed before the decimal total is calculated, so 8.25 means 8.25 hours actually worked.
Examples
From hh:mm to decimal
A 38:45 week is 38.75 decimal hours. The calculator shows both so you can copy whichever your system needs.
Single shift
8:00 AM to 4:15 PM with no break is 8:15, or 8.25 decimal hours.
Tips
- For pay, let the tool compute gross from exact minutes — rounding decimals first can cost a few cents.
- Decimal hours are the standard import format for most payroll software.
Minutes to decimal hours
Payroll usually wants decimal hours. Divide minutes by 60:
| Minutes | Decimal |
|---|---|
| 15 | 0.25 |
| 30 | 0.50 |
| 45 | 0.75 |
| 60 | 1.00 |
Printing & exporting your timesheet
Use Print / save as PDF for a clean report — ads, navigation, and controls are removed automatically by the print styles, leaving just your hours and totals. Use Export CSV to download a spreadsheet you can import into payroll or open in Excel or Google Sheets.
Frequently asked questions
What are decimal hours?
Decimal hours express time as a number with a fractional part instead of minutes — 8 hours 15 minutes becomes 8.25.
How do I get the hh:mm version back?
Multiply the fractional part by 60. For 8.25, that's 0.25 × 60 = 15 minutes, so 8:15.
