1099 vs W2 Income Comparison Calculator

Deciding between a W2 job offer and a 1099 contract at the same headline pay is really two different math problems in disguise. A W2 employer withholds federal and payroll (FICA) tax, splits Social Security and Medicare with you, and usually throws in health insurance and a 401k match. A 1099 contractor owes self-employment tax on top of income tax, pays 100% of their own FICA-equivalent, and gets no employer benefits — but can deduct business expenses, a home office, retirement contributions and half of their self-employment tax. This calculator runs both scenarios side by side for the same gross income so you can compare actual take-home pay, not just the rate on the contract.

How to use it

1. Enter your filing status and annual gross income (the number on the offer or contract).
2. Enter your state income tax rate as a flat percentage, or leave it at 0 if your state has no income tax.
3. Fill in the W2 side: monthly employer health insurance contribution, employer 401k match percentage, and the annual value of other benefits (dental, vision, life insurance, etc.).
4. Fill in the 1099 side: your own monthly health insurance cost, annual retirement contributions (SEP-IRA, Solo 401k), deductible business expenses, and home office deduction.
5. The comparison table and summary update automatically as you type.

The table walks through gross income, federal income tax, state tax, Social Security, Medicare, the above-the-line self-employment tax deduction, health insurance, retirement, other benefits and business expenses, before landing on total take-home pay, effective tax rate, an hourly rate (based on a 2,080-hour work year), and a "Total Value" row that adds employer benefits back on top of W2 take-home pay for a fair, apples-to-apples comparison against 1099 income (which has no separate benefits to add).

Why 1099 contractors pay more payroll tax

A W2 employee pays 7.65% of wages toward Social Security and Medicare, and the employer quietly pays the other 7.65% on their behalf. A 1099 contractor is both employer and employee, so they owe the full 15.3% self-employment tax rate — before income tax. The calculator applies the standard self-employment adjustment (92.35% of net income) and the IRS above-the-line deduction for half of that self-employment tax, so the comparison reflects actual current tax rules rather than a naive doubling.

What this calculator doesn't account for

It's an estimate, not a tax return. It uses flat federal brackets and a flat state rate — it doesn't model state-specific brackets, the Qualified Business Income (Section 199A) 20% pass-through deduction available to many contractors, itemized deductions, tax credits, or local taxes. Actual take-home pay depends on your full financial picture. Use this to sanity-check an offer, then talk to a CPA before signing anything.

Is a higher 1099 rate always worth it?

Not automatically. A contract rate needs to beat the equivalent W2 salary by roughly the value of the benefits you'd give up — employer health insurance, 401k match, paid time off, unemployment insurance eligibility and the employer's half of payroll tax — plus a margin for the self-employment tax hit and the extra bookkeeping and income volatility that come with 1099 work. This calculator's "Total Value" row is a starting point for that math, not the whole picture.
