What this calculator estimates
Convert an employee-equivalent salary into a contractor billing rate using benefits, taxes, overhead, utilization and profit margin.
How to use it
Enter Comparable employee salary ($); Benefits value (% of salary); Employer payroll taxes (%); Business overhead (% of direct cost); Billable hours per week; Billable weeks per year; Target profit margin (%). Select Calculate to update the results.
How the calculation works
Salary is increased for benefits and employer taxes, then for business overhead. The resulting annual cost is divided by billable hours and grossed up for target margin.
