How payroll time conversion works
Clock time is base-60 (60 minutes per hour), but payroll software needs base-10 decimals so it can multiply hours by a pay rate. The formula: decimal hours = hours + (minutes / 60).
Say you worked 8 hours and 45 minutes. That is 8 + (45 / 60) = 8.75 decimal hours. At $20/hr, your gross pay is 8.75 × $20 = $175.00. Without that decimal conversion, the payroll system has no way to do this math.
One thing that trips people up: 0.50 hours is 30 minutes, not 50 minutes. Decimal hours run on base-10, clock minutes on base-60, so the numbers never line up the way you'd expect. Stick with the formula instead of eyeballing it.
Going the other direction, take the decimal part and multiply by 60. For 8.75 hours: 0.75 × 60 = 45 minutes, so you get 8 hours and 45 minutes.
FLSA rounding rules for time conversion
The Fair Labor Standards Act (29 CFR 785.48) lets employers round employee time to the nearest 5, 6, or 15 minutes. The most widely used approach is the "7-minute rule" for quarter-hour rounding: 1–7 minutes past the quarter hour rounds down, 8–14 minutes rounds up.
Rounding has to be applied consistently and cannot tilt in the employer's favor over time. The Department of Labor has confirmed that rounding to 2 decimal places in payroll software is fine. More employers are switching to exact time tracking to sidestep rounding disputes altogether.

Common payroll time conversion mistakes
- Confusing decimal hours with minutes. 0.75 hours is 45 minutes, not 75. Multiply the decimal by 60 to get minutes.
- Inconsistent rounding. Mixing rounding methods within a pay period can create FLSA violations. Pick one and stick with it.
- Repeating decimals. Some conversions never terminate (20 minutes = 0.3333...). Standard payroll rounds to 2 decimal places, giving 0.33.
- Wrong conversion direction. Multiplying when you should divide, or the other way around. Minutes to decimal: divide by 60. Decimal to minutes: multiply by 60.
- Forgetting break time. Subtract unpaid breaks before converting to decimal hours.
If something looks off, check your conversion against the chart above. Two decimal places gets you within about 36 seconds of the real value, which is plenty for payroll.
Frequently Asked Questions
Common questions about payroll time conversion
How do I convert minutes to decimal hours for payroll?
Divide the minutes by 60. So 45 minutes / 60 = 0.75. Add that to your whole hours: 8 hours and 45 minutes becomes 8.75. Payroll systems need time in this decimal format before they can calculate wages.
What is the 7-minute rule for time rounding?
With quarter-hour rounding (FLSA-compliant), 1–7 minutes past the quarter hour gets rounded down and 8–14 minutes gets rounded up. So a 9:07 AM clock-in becomes 9:00 AM, but 9:08 AM becomes 9:15 AM. Employers have to apply this rule consistently, not just when it benefits them.
Why does payroll use decimal hours instead of minutes?
Because payroll software multiplies hours by a pay rate. With decimal hours, that math is direct: 8.75 hours × $20/hr = $175.00. If you left the time as 8:45, the system would need an extra conversion step before it could calculate pay.
How do I convert decimal hours back to minutes?
Grab the decimal part and multiply by 60. With 8.75 hours, the .75 part times 60 gives you 45 minutes. So 8.75 decimal hours = 8 hours and 45 minutes. Handy for double-checking timesheet entries or reading payroll reports in clock time.
What decimal places should I use for payroll?
Two decimal places (hundredths of an hour) is the standard. The Department of Labor recommends it, and payroll providers like ADP and Paychex default to it. Two decimals gets you within about 36 seconds of the exact time, which is more precision than payroll needs.
Is 0.50 hours the same as 50 minutes?
No, and this catches people all the time. 0.50 decimal hours is 30 minutes (0.50 × 60 = 30), not 50. The confusion happens because decimal hours are base-10 and clock minutes are base-60. Use the formula (minutes / 60) instead of guessing.
How do employers round time for payroll?
The FLSA allows rounding to the nearest 5 minutes, 6 minutes (1/10th of an hour), or 15 minutes (1/4 hour). The catch: rounding has to be neutral over time and cannot consistently shortchange employees. A growing number of payroll systems skip rounding entirely and use exact decimal conversion.
What is 7 hours and 53 minutes in decimal?
It is 7.88 decimal hours. Here is the math: 53 / 60 = 0.8833, which rounds to 0.88 at 2 decimal places. Total: 7 + 0.88 = 7.88. If you earn $20/hr, that comes to $157.60 gross.
