1. Minutes to a fraction of an hour: 45 min ÷ 60 = 0.75
2. Seconds to a fraction of an hour: 0 sec ÷ 3600 = 0.0000
3. Add it all up: 7 + 0.75 + 0/3600 = 7.75
How to Convert Time to Decimal
Every timesheet eventually needs a time to decimal conversion before a pay rate can touch it, and the arithmetic only takes three short steps. The calculator above runs the same conversion live, so you can check your own timesheet against it line by line.
- Divide the minutes by 60. Minutes are a fraction of an hour, so 45 minutes becomes 45 ÷ 60 = 0.75. This is the step people skip when they try to convert time to decimal in their head, and it is where the $6 payroll error below comes from.
- Add the fraction to the whole hours. Take the whole-hour count from the time card and add the fraction from step one — this is the moment you actually convert time to decimal. Seven hours plus 0.75 gives 7.75, the decimal hours figure a payroll system actually wants.
- Round to your payroll policy. Some employers keep four decimal places for exact time to decimal precision; most payroll software rounds to two decimals, which is why "2 decimals (payroll standard)" is the default above.
Worked example: a clerk clocks in at 9:00 a.m. and out at 4:45 p.m., with the seconds field showing 00. That is 7 hours and 45 minutes, or 7:45 on the clock. Run it through the time to decimal calculator and the result is 7.75 decimal hours — the number that goes straight into a payroll spreadsheet.
Why Payroll Uses Decimal Hours
Pay rates are decimal numbers, and decimal numbers only multiply correctly against other decimal numbers. Skip the time to decimal step and the arithmetic breaks: a clock reading of 7:45 is not the decimal 7.45 — it is 7.75 once you convert time to decimal properly. Multiply $20 by 7.45 by mistake and a payroll clerk pays $149.00 for the shift instead of the correct $155.00 from $20 × 7.75. That $6.00 gap looks small on one shift, but multiplied across a biweekly timesheet with dozens of clock-ins, a whole department's payroll can drift by real money every single pay period — all from skipping the time to decimal conversion.
This is also where rounding policy matters. Many employers round clock times to the nearest quarter hour before running the time to decimal calculator, and the Fair Labor Standards Act (FLSA) permits 15-minute rounding as long as it is applied neutrally — rounding both up and down over time, not always down against the employee. Payroll teams that document a fixed rounding rule and apply it consistently to every timesheet stay on the right side of that requirement; the rounding selector above mirrors the same idea by giving you a documented, repeatable rule instead of ad hoc math.
A spreadsheet takes the error out of the multiplication but not out of the conversion — the cells still need the time to decimal step done somewhere. Whether that happens in a formula or in this time to decimal calculator, the rule stays the same: convert time to decimal first, multiply second. Teams that pin the time to decimal habit down once stop finding drift at audit time.
Quick Reference Table
For a fast lookup without touching the calculator, here is how common minute values convert to decimal hours — a time to decimal shortcut for the values that come up on almost every timesheet. This is the same time to decimal table payroll clerks tape above a time clock.
| Minutes | Decimal hours |
|---|---|
| 5 | 0.08 |
| 10 | 0.17 |
| 15 | 0.25 |
| 20 | 0.33 |
| 30 | 0.50 |
| 40 | 0.67 |
| 45 | 0.75 |
| 50 | 0.83 |
Need every minute value from 1 to 59, not just the common ones? The full minutes to decimal chart lists every row so you never have to run the time to decimal calculator for a single lookup. Bookmark whichever time to decimal reference you use most — the table above or the full chart — and payroll day gets shorter.
Time to Decimal FAQ
How do you convert time to decimal?
Divide the minutes by 60 and add the result to the whole hours; if you are tracking seconds, divide those by 3600 and add them too. That single formula is the whole time to decimal conversion, and it is exactly what this time to decimal calculator runs on every keystroke.
What is 7:45 in decimal?
7.75. Forty-five minutes divided by 60 is 0.75, and 7 whole hours plus 0.75 is 7.75 decimal hours — the figure a time to decimal calculator or payroll system expects for a 7-hour-45-minute shift.
How do I convert time to decimal in Excel?
Excel stores clock times as fractions of a day, so multiply the time cell by 24 and format the result as a plain number: =A1*24. If A1 holds 7:45, that formula returns 7.75, matching the time to decimal calculator above exactly.
What is the 15-minute rounding rule?
It is the FLSA-permitted practice of rounding clock-in and clock-out times to the nearest quarter hour before you convert time to decimal — as long as the rounding is applied neutrally over time rather than consistently shaving minutes off the employee's side.
Is there a decimal time calculator for payroll?
Yes — this page is a free time to decimal payroll calculator built for exactly that job. It works equally well as a plain time to decimal calculator for freelancers logging billable hours. Enter hours, minutes and seconds, choose a rounding level, and copy the decimal result straight into a payroll system or spreadsheet; no account and no software install required.

Already used the time to decimal calculator above? Need to go the other way? The decimal to time calculator takes a decimal figure like 7.75 and turns it back into hours and minutes for a time card. And once you convert time to decimal and multiply by an overtime rate, the last step is the time and a half calculator.
