1099 vs W-2 Calculator
A 1099 vs W-2 calculator is a tool that compares your take-home pay as a self-employed 1099 contractor against the same headline pay earned as a W-2 employee. At equal pay a contractor usually nets less, because they owe both halves of Social Security and Medicare as self-employment tax — 15.3% on 92.35% of net earnings — while an employer covers half of that for a W-2 worker. This calculator estimates federal income tax plus FICA or SE tax plus a flat state rate for each path, then solves for the 1099 gross that would match the W-2 net, giving you a "markup" to quote. It is a TY2025 estimate, not tax advice.
Use cases
Decide whether to accept a contract rate
When a client offers a 1099 rate that looks similar to your old W-2 salary, this shows why it is not an equal offer. The self-employment tax alone claws back the employer’s half of FICA, so a matching net requires a higher gross. Seeing both take-home figures side by side helps you judge whether the contract rate is actually a raise or a quiet pay cut.
Set a fair 1099 markup to quote
If you want the same take-home you had on payroll, you need to charge more as a contractor. The tool solves for the 1099 gross that produces the same net as a given W-2 salary, so you can quote a defensible rate. Treat it as a floor for negotiation — the real gap is wider once lost benefits and unpaid gaps are counted.
Budget for quarterly estimated taxes
W-2 workers have tax withheld automatically; contractors usually send quarterly estimated payments instead. Seeing the combined federal, self-employment, and state tax on your 1099 income gives a rough annual figure you can divide into four, so a tax bill at year-end is less likely to catch you off guard. It is an estimate, so keep a buffer.
Compare offers across states
A contract in a no-income-tax state can net more than a higher-paying one where state tax bites. By entering a flat state rate for each scenario, you can compare take-home rather than headline pay. The state model here is a single flat percentage, so it will not capture brackets, local taxes, or credits — use it for a quick side-by-side, not a filing.
Explain the gap to a client or partner
The "why do contractors cost more?" conversation is easier with real numbers. A clear breakdown of employer-paid FICA, the extra self-employment tax, and the resulting markup makes the difference concrete for a client sizing a budget or a friend weighing whether to leave a salaried job — no hand-waving about taxes simply "being higher" and no guessing at the size of the gap.
How it works
- Enter the headline pay — Type the annual amount both paths are compared at — the W-2 salary or the 1099 gross you want to test.
- Choose the comparison — Compare the two at equal pay, or ask the tool to solve for the 1099 gross that matches a target W-2 net.
- Add a state rate — Enter a single flat state income-tax percentage (0 for no-tax states), applied to both scenarios.
- Let it compute the taxes — It estimates federal income tax, then FICA for the W-2 side and self-employment tax on 92.35% of net for the 1099 side.
- Read the take-home and markup — See each net figure, the difference, and the 1099 gross needed to match the W-2 net — your markup to quote.
Examples
Input: $100,000, equal comparison, 5% flat state
Output: 1099 nets about $7,000 less than W-2
Input: Match the net of an $80,000 W-2 salary, 0% state
Output: ≈ $86,000–$88,000 1099 gross needed
Input: $60,000 headline, equal comparison, 0% state
Output: Similar federal tax, 1099 pays extra SE tax
Frequently asked questions
Why does a 1099 contractor take home less at the same pay?
A W-2 employee splits Social Security and Medicare taxes with their employer, who pays half. A 1099 contractor pays both halves as self-employment tax — 15.3% on 92.35% of net earnings — so at identical pay the contractor keeps less.
What is the self-employment tax rate?
It is 15.3% (12.4% Social Security up to the annual wage base, plus 2.9% Medicare) applied to 92.35% of your net self-employment earnings. You can deduct half of it when figuring federal income tax, which this estimate includes.
What is the 1099 "markup"?
It is the higher gross a contractor must charge to end up with the same take-home as a given W-2 salary. The tool solves for it so you can quote a rate that offsets the extra self-employment tax.
Does this include benefits, PTO, or unemployment insurance?
No. It models federal income tax, FICA or SE tax, and a flat state rate only. It leaves out health insurance, retirement match, paid time off, unemployment and workers’ comp coverage, and unpaid gaps between contracts — all of which make the real contractor gap wider.
Does it account for the QBI deduction?
No. The Section 199A qualified business income deduction can reduce a contractor’s taxable income but has income limits and phase-outs this simplified tool does not model, so your actual 1099 tax may be lower than shown.
How is state tax handled?
As a single flat percentage applied to both paths. Real state taxes have brackets, standard deductions, and sometimes local taxes, so treat the state figure as a rough adjustment, not a filing-ready number.
Is this tax advice?
No. It is a TY2025 educational estimate using published federal figures. Rates, wage bases, and your personal deductions vary, so confirm anything that affects a real decision with a qualified tax professional.
Tips
- Compare take-home pay, not headline rate — the same number means very different money as 1099 vs W-2.
- When quoting a contract rate, start from the markup and add a cushion for benefits and unpaid gaps.
- Set aside the estimated self-employment plus income tax from each payment so quarterly taxes are covered.
- Remember the half-of-SE-tax deduction and a possible QBI deduction can lower your real 1099 tax below this estimate.
- Use a 0% state rate for no-income-tax states, and check local city taxes separately.
