How do freelancers calculate billable hours worked?

Freelancers record start and end timestamps for each project, subtract non-billable interruptions, and convert the total time to decimal hours. Multiplying total decimal hours by the client’s hourly contract rate produces the billable invoice total.

How do you convert 45 minutes into decimal hours?

Divide 45 by 60: 45 ÷ 60 = 0.75. So, 8 hours and 45 minutes equals 8.75 decimal hours.

Subtract your start time from your finish time, then subtract any unpaid breaks. For example, starting at 9:15 AM and finishing at 5:45 PM is 8 hours and 30 minutes of elapsed time. Subtracting a 30-minute lunch leaves exactly 8 hours and 0 minutes worked.
