To convert hours to decimal, keep the whole hours and divide the minutes by 60, then add the two together. So 8 hours 15 minutes becomes 8 + (15 ÷ 60) = 8.25 decimal hours. That decimal figure is what payroll systems and spreadsheets need before they can multiply your time by an hourly rate. Use the free converter below for an instant answer plus optional gross pay.
This calculator from Anchor AI Tools turns hours and minutes into decimal hours, and — if you add a pay rate — shows the gross pay too, so you can check a timesheet or invoice in one step.
Quick Answer: To convert hours to decimal, divide the minutes by 60 and add the result to the whole hours. For example, 8 hours 15 minutes = 8 + (15 ÷ 60) = 8.25 decimal hours, and 7 hours 45 minutes = 7.75 decimal hours. Multiply the decimal by your hourly rate to get pay: 7.75 × $20 = $155.
Enter hours and minutes below. Add an hourly rate if you want gross pay too, then click Convert and copy the decimal value into your payroll system, spreadsheet, or invoice.
Keep the hours; divide minutes by 60; add them together.
Converting just the minutes? Use the minutes to decimal converter. To go the other way — decimal back to clock time — see decimal to time.
Decimal Hours = Hours + (Minutes ÷ 60)
The hours stay the same; only the minutes are convertedAn hour contains 60 minutes, so each minute is worth 1/60 of an hour. To convert any hours-and-minutes time, you keep the whole hours unchanged and divide just the minutes by 60, then add the two parts together.
This chart shows common hours-and-minutes values and their decimal equivalents. The highlighted rows are the quarter-hour marks payroll uses most. Bookmark or print this page for quick reference.
| Time | Decimal | Time | Decimal |
|---|---|---|---|
| 0:15 | 0.25 | 5:00 | 5.00 |
| 0:30 | 0.50 | 6:30 | 6.50 |
| 0:45 | 0.75 | 7:15 | 7.25 |
| 1:00 | 1.00 | 7:45 | 7.75 |
| 1:30 | 1.50 | 8:00 | 8.00 |
| 2:15 | 2.25 | 8:15 | 8.25 |
| 3:20 | 3.33 | 8:30 | 8.50 |
| 4:10 | 4.17 | 8:45 | 8.75 |
| 4:40 | 4.67 | 9:00 | 9.00 |
| 4:50 | 4.83 | 40:20 | 40.33 |
Pro tip: The quarter marks repeat every hour — 0.25, 0.50, 0.75. For any other minute value, divide by 60. For example, 20 minutes ÷ 60 = 0.3333, which rounds to 0.33.
Converting hours to decimal correctly prevents under- or over-paying on every timesheet.
📋 Convert 7h 45m at $20/hr
Keep 7 hours. 45 ÷ 60 = 0.75. So 7 + 0.75 = 7.75 decimal hours. Pay: 7.75 × $20 = $155.00.
📋 Convert 40h 20m at $25/hr
Keep 40 hours. 20 ÷ 60 = 0.3333 ≈ 0.33. So 40.33 decimal hours (displayed rounded). Using the exact value for pay: 40.3333 × $25 = $1,008.33.
⚠️ The most common mistake
30 minutes is half an hour, so 0.50 — not 0.30. Entering 8.30 instead of 8.50 undercounts 12 minutes per shift.
You cannot multiply a clock time by a wage directly. 8:30 means 8 hours 30 minutes, but typing 8.30 × $20 gives the wrong answer because the minutes are not a true decimal yet. Converting to 8.50 first lets standard arithmetic work: 8.50 × $20 = $170.00.
Under the U.S. Department of Labor's interpretation of the Fair Labor Standards Act, employers must keep accurate records of hours worked. Converting clock hours to decimal is the standard method payroll teams use to calculate regular pay, overtime, and labour-cost reports correctly. For the complete workflow including overtime, read our guide to converting time to decimal for payroll.
If hours are in one cell and minutes in another, add them with the minutes divided by 60. If you have a clock-in and clock-out time stored as time values, subtract and multiply by 24:
Format the result cell as Number (not Time) with two decimal places. For tax or benefit deductions on the pay figure, pair this with the percentage calculator.
This conversion is everyday work for payroll administrators calculating wages, employees checking their own pay, freelancers billing hourly clients, HR teams processing time cards, accountants tracking labour costs, and small business owners running payroll by hand. Anyone multiplying worked time by a rate needs decimal hours first.
