How the 1099 vs W-2 estimate works
This calculator compares two common ways to earn income: W-2 employee wages and 1099 contractor revenue. It estimates federal income tax, payroll or self-employment tax, optional state tax, business expenses, and pre-tax W-2 deductions so you can compare estimated take-home income side by side.
W-2 estimate
For employee income, the calculator starts with gross wages, subtracts pre-tax deductions and the standard deduction, then estimates federal income tax, employee FICA, and optional state tax.
1099 estimate
For contractor income, it starts with gross revenue, subtracts business expenses, estimates self-employment tax, applies the half-SE-tax deduction, and estimates federal and optional state tax.
What the difference means
The final difference shows estimated 1099 net income minus estimated W-2 net income. A higher 1099 number does not automatically mean the contractor offer is better.
What to include in the comparison
A contractor rate often needs to be higher than an employee salary because a contractor may pay both sides of Social Security and Medicare taxes, cover their own benefits, buy equipment, pay for insurance, and handle unpaid time off. A W-2 role may have a lower gross number but include health insurance, retirement matching, paid leave, unemployment insurance, and more predictable withholding.
- Enter W-2 gross wages before tax withholding.
- Enter W-2 pre-tax deductions such as traditional 401(k), HSA, or eligible premiums.
- Enter 1099 gross revenue before expenses.
- Enter ordinary business expenses you expect to deduct from contractor revenue.
- Use the state tax field only as a rough flat-rate estimate.
Example: comparing an employee job to contract work
Suppose a job offer pays $80,000 as a W-2 employee and a contract offer pays $95,000 as a 1099 contractor. At first glance, the contract offer looks better. But if the contractor has $6,000 of business expenses and must pay self-employment tax, the net difference may shrink.
The calculator helps show that tradeoff. It does not place a dollar value on health insurance, retirement match, paid time off, job stability, or administrative time, so those should be added to your personal comparison.
Important assumptions
The estimate uses simplified federal tax logic and a flat optional state tax rate. It does not model itemized deductions, credits, the qualified business income deduction, local tax rules, retirement plan differences, health insurance deductions, or every state-specific rule.
For a quick decision, this is useful directional math. For a final tax plan, compare the estimate with payroll records, IRS guidance, state tax guidance, or a qualified tax professional.

FAQ
How much more should a 1099 contractor make than a W-2 employee?
There is no single rule, but contractors often need a higher gross rate to cover self-employment tax, benefits, unpaid time off, business expenses, insurance, and admin time. This calculator helps estimate the tax side, but benefits and risk still need a separate dollar value.
Does this calculator include the qualified business income deduction?
No. The QBI deduction can be important for some self-employed people, but eligibility depends on income, business type, and other rules. This calculator keeps the estimate simpler and more conservative.
Why does the 1099 side include self-employment tax?
W-2 employees pay the employee share of Social Security and Medicare taxes through payroll. Self-employed workers generally pay both the employee and employer portions through self-employment tax, with a partial deduction for income tax purposes.
Should I compare annual salary or hourly rates?
Use annual amounts when possible. If you only have an hourly rate, estimate annual income by multiplying the rate by expected billable hours. For contract work, remember that unpaid holidays, sick time, and gaps between projects can reduce annual revenue.
