How this calculator works
Planning comparison only. It uses a simplified 15.3% self-employment tax and 7.65% employee FICA before income tax; the actual SE-tax base and deduction are more complex.
Worked example
The same gross pay can have different economics after contractor expenses, self-employment tax, and employee benefits.
Assumptions and limits
Inputs are treated as non-negative U.S. dollar amounts. Results are rounded to cents where useful. This tool is for planning and does not determine legal eligibility, payroll compliance, or final tax liability.
