W2 vs 1099 Calculator

The W-2 vs 1099 Calculator compares a simplified employee package with a contractor package. Enter W-2 income and benefits, then enter 1099 income and contractor expenses. The calculator estimates payroll taxes, self-employment tax, net value, and which option produces the higher modeled value.

What the model includes

For the W-2 side, the model subtracts an employee FICA estimate from gross income and adds the supplied benefits value. For the contractor side, it subtracts business expenses, calculates self-employment tax on 92.35% of net business income, and subtracts that tax.

The implementation uses a static Social Security wage-base assumption and fixed tax rates. It does not calculate federal income tax, state income tax, deductions, retirement contributions, health-insurance premiums, paid leave, or worker-classification rules.

Calculation outline

$\text{W-2 net value}=\text{W-2 income}-\text{FICA estimate}+\text{benefits}$ $\text{Net business income}=\max(0,\text{1099 income}-\text{contractor expenses})$ $\text{Self-employment tax base}=\text{Net business income}\times0.9235$ $\text{1099 net value}=\text{Net business income}-\text{self-employment tax}$

The displayed difference is the absolute gap between the two modeled net values. The better-option label reflects only this simplified calculation.

Worked example

Suppose W-2 income is $90,000 with$6,000 in benefits, while contractor income is $105,000 with$10,000 in expenses.

1. W-2 FICA is estimated from the static wage-base and rate assumptions.
2. Contractor net business income is $105,000 - $10,000 = $95,000.
3. Self-employment tax is applied to 95,000 x 0.9235 using the model's brackets.
4. The two resulting net values are compared, and the larger modeled value is labeled W-2, 1099 Contractor, or Equal.

How to use the result

Use the comparison as a starting point for negotiating compensation, not as a tax filing result. A contractor rate may need to cover equipment, unpaid administration, gaps between contracts, insurance, retirement saving, and the employer-side costs normally associated with employment.

Questions

Does the calculator include federal income tax?

No. It models FICA and self-employment tax only, plus the supplied benefits and expenses. Federal, state, and local income tax can materially change the comparison.

Are benefits treated as cash wages?

The W-2 benefits input is added directly to modeled W-2 net value. Enter a realistic annual value for the benefits you would actually use; the calculator does not value individual benefit types.

Does a 1099 label decide worker classification?

No. Worker classification depends on the facts of the working relationship and applicable law. The calculator compares compensation assumptions and does not provide legal advice.

Limitations

Tax rates and wage bases can change, and the static assumptions in this tool may not match your jurisdiction or tax year. Verify the result with current IRS guidance and a qualified tax professional before making a contract or employment decision.
