Enter whole hours, extra minutes and the agreed rate. The calculator converts the minutes to a decimal, adds them to the hours and calculates the billable amount. For example, 2 hours 30 minutes becomes 2.5 billable hours.
Use the decimal-hours result on a timesheet or invoice line. If your contract allows rounding, round time consistently and disclose the increment.
Minutes to decimal hours
Divide minutes by 60: 6 minutes is 0.1 hour, 15 minutes is 0.25, 30 minutes is 0.5 and 45 minutes is 0.75. Multiply total decimal hours by the hourly rate for the billable amount.
For multiple sessions, calculate each accurately or total the raw minutes before converting. Repeatedly rounding individual entries can overstate time.
