Formula Used

This calculator uses a simplified effective-rate approach for fast planning. It is ideal for screening compensation structures, not filing returns.

Combined tax rate = Federal tax rate + State or local tax rate
Employee taxable income = Gross pay + Bonus − Pretax deductions − Retirement contributions − Employee deduction amount
Employee income tax = Employee taxable income × Combined tax rate
Employee payroll tax = Employee gross pay base × Employee payroll tax rate
Employee net cash = Gross pay base − Pretax deductions − Retirement contributions − Total employee tax
Employee total value = Employee net cash + Employer-paid benefits value
Contractor business profit = Contractor revenue − Business expenses
Contractor taxable income = Business profit − Health insurance − Retirement − Contractor deduction amount
Contractor income tax = Contractor taxable income × Combined tax rate
Self-employment tax = Contractor business profit × Self-employment tax rate
Contractor net cash = Revenue − Business expenses − Insurance − Retirement − Replacement benefits cost − Total contractor tax
Break-even contractor revenue is estimated with iterative search until contractor net cash matches employee total value.

FAQs

1. What does this calculator compare?

It compares employee take-home value against contractor after-tax cash. It also includes benefits, payroll taxes, business expenses, and a client or company cost view.

2. Why can a contractor owe more tax?

Contractors often pay both income tax and self-employment tax. They may also cover insurance, unpaid leave, and retirement costs that employees partly receive through employers.

3. Should I include employer benefits?

Yes. Health coverage, retirement matches, paid time off, and other perks can materially change the true employee value, even if cash salary looks lower.

4. Can I model different tax environments?

Yes. You can change federal, state, payroll, self-employment, and employer payroll rates. This makes the tool useful for quick scenario planning across locations or contract structures.

5. Is the break-even revenue estimate exact?

No. It is a planning estimate based on your effective rates and deduction assumptions. It helps show the contractor revenue needed to match employee value.

6. Are deductions handled differently for both paths?

Yes. Employee pretax deductions reduce the employee tax base, while contractor business expenses reduce business profit before tax calculations. Separate deduction fields let you test both cases clearly.

7. Can this tool decide legal worker classification?

No. It measures financial impact only. Legal classification depends on labor rules, control tests, contract terms, and local regulations, which require separate review.

8. When is the contractor path usually stronger?

It usually improves when contractor revenue is high enough to offset self-employment tax, lost benefits, insurance costs, and unpaid downtime. The break-even revenue figure helps test that threshold.
