Employee vs. working for yourself Your scenario
A model, not a market rate. It shows the minimum you'd need to bill to match a $66,500 employee salary once you cover what an employer normally pays for. Change any number.
Minimum billing rate
How this calculator works. Billable hours are hours you can charge a customer. Driving, quoting, paperwork and slow weeks aren't billable, which is why 1,400 is a common starting point versus 2,080 paid hours as an employee.
