Payroll Hours Conversion Chart & Decimal Calculator

Convert hours and minutes into payroll decimal hours, reverse decimals back into time, and estimate gross pay. Use the complete 1–60 minute chart for timesheets, invoices, payroll entry, and contractor billing.

Payroll minutes to decimal hours calculator

Enter worked hours and minutes. The calculator divides minutes by 60, adds the whole hours, and optionally multiplies the result by an hourly rate.

Hours and minutes to decimal

8 hours 30 minutes = 8.50 decimal hours

Decimal hours to hours and minutes

1.75 hours = 1 hour 45 minutes

Quick rule

Minutes to decimal: divide by 60.
Decimal to minutes: multiply the decimal part by 60.

How payroll time conversion works

Payroll systems normally store time as decimal hours because decimal values can be multiplied directly by an hourly rate. Minutes are based on 60, not 100, so the number after the decimal is not a minute count.

Decimal hours = whole hours + (minutes ÷ 60)

Example: 8 hours 45 minutes = 8 + (45 ÷ 60) = 8.75 hours.

Important: 1 hour 45 minutes is 1.75 hours, not 1.45 hours. Treating minutes as hundredths is one of the most common timesheet errors.

Worked payroll and billing examples

Shift with an unpaid break

An employee works from 8:15 AM to 5:00 PM with a 30-minute unpaid break. The elapsed time is 8 hours 45 minutes. After subtracting the break, paid time is 8 hours 15 minutes, or 8.25 decimal hours.

Weekly timesheet total

A total of 38 hours 40 minutes becomes 38 + (40 ÷ 60) = 38.6667 hours. Displayed to two decimal places, that is 38.67 hours.

Freelancer invoice

Two hours 20 minutes is 2.3333 hours. At $100 per hour, the unrounded calculation is 2.3333 × $100 = $233.33.

Overtime calculation

Convert the total worked time first, then separate regular and overtime hours according to the rules that apply to the worker. Keep sufficient decimal precision until the final pay calculation.

Excel and Google Sheets formulas

Use these formulas when preparing a timesheet or payroll worksheet:

  • Minutes in A2 to decimal hours: =A2/60
  • Start time in A2 and end time in B2: =(B2-A2)*24
  • Subtract break minutes in C2: =((B2-A2)*24)-(C2/60)
  • Gross pay when decimal hours are D2 and rate is E2: =D2*E2

Format the result cell as a number rather than a clock time. For overnight shifts, use a formula or time-entry method that correctly handles the date change.

Conversion, display rounding, and payroll policies

Converting minutes to decimal hours is a mathematical operation. Rounding that number for display is different from changing recorded clock-in or clock-out times under a workplace policy. Use the actual recorded time and the precision your payroll system requires. If an organization applies a time-rounding policy, confirm that policy with the responsible payroll professional and applicable requirements.
