A 1099 contractor who bills $50 an hour looks like they are earning less than a W-2 employee offered $70 an hour — but that comparison is misleading. Contractors pay the full 15.3% self-employment tax, buy their own health insurance, fund their own retirement, and get no paid time off. W-2 employees, by contrast, pay only half of FICA (7.65%), receive employer-paid benefits worth 25–35% of salary, and get health insurance, 401(k) matches and PTO bundled in. This calculator turns your billed contractor rate into the net dollars you actually keep, then compares it side-by-side with a W-2 offer so you can see which path pays more in real terms.
Type your rate, your annual hours, and the W-2 offer you are weighing. Every figure updates instantly, and the result card shows both your after-tax contractor take-home and the W-2 salary that would be financially equivalent.
How to Use
- Enter your Contractor Hourly Rate — the amount you bill clients, before any business expenses.
- Set Billable Hours / Year. A standard full-time schedule is 2,080 hours (40 hours a week for 52 weeks). If you only bill 30 hours a week because of admin, sales and downtime, enter 1,560 instead.
- Adjust the Self-Employment Tax Rate. The default 15.3% is the full Social Security and Medicare tax on Schedule SE. If you want to also estimate federal and state income tax on top, raise this to 25% or 30% to see your true after-tax number.
- Type the W-2 Hourly Offer you are comparing against. Leave it at 0 if you only want to model your contractor take-home.
- Set W-2 Benefits Value as a percentage of wages. The default 30% is a realistic average: employer health insurance contributions, FICA match, 401(k) match, paid time off, and unemployment and workers' comp typically add up to roughly a third of base pay.
- Add your Annual Business Expenses — software subscriptions, equipment, professional insurance, home-office share, and travel. These are deducted before self-employment tax, so they lower your tax bill directly.
The result card breaks out your gross contractor revenue, the self-employment tax you will owe, your net annual pay, and your effective after-tax hourly rate. On the W-2 side it shows the gross salary, the benefits value, and the total compensation package, and finally the equivalent W-2 salary you would need to earn the same after-tax dollars as a contractor.
How Contractor Tax Works
When you work as a W-2 employee, your employer withholds 7.65% of your pay for Social Security and Medicare, then matches that 7.65% on their own dime. When you are self-employed, the IRS charges you the full 15.3% as the self-employment tax on Schedule SE. You do get one break: only 92.35% of your net self-employment earnings are subject to the 15.3% tax, which is why many calculators show an effective rate near 14.1% rather than the full 15.3%. This tool uses the simpler 15.3% on your net earnings after expenses; bump the rate up yourself if you also want to layer federal and state income tax into the picture.
On top of self-employment tax, contractors must send quarterly estimated taxes (April, June, September, January) because nothing is withheld from client invoices. Underpay by too much during the year and the IRS can charge an underpayment penalty, so setting aside 25–30% of every invoice into a separate tax account is a common rule of thumb.
Why the W-2 Benefits Line Matters
A W-2 salary is not just the number on your offer letter. Employers pay:
- Employer FICA match — an extra 7.65% of wages on top of what you pay.
- Health insurance premiums — often $6,000–$12,000 a year per employee.
- 401(k) match — typically 3–6% of salary, which is free retirement money.
- Paid time off — two weeks of PTO is worth roughly 8% of annual pay.
- Workers' compensation, unemployment tax and disability insurance — legally required in most states.
Stacked together, these benefits are worth 25–35% of base salary. A W-2 job paying $70 an hour is really paying close to $91 an hour once benefits are counted, which is why a contractor billing $70 an hour may still come out ahead in take-home pay even after self-employment tax.
Examples
Example 1 — The default comparison. A contractor bills $50 an hour for 2,080 hours a year. Gross revenue is $104,000. At the 15.3% self-employment tax rate, they owe $15,912 in SE tax and net $88,088 — an effective after-tax hourly rate of about $42.35. The W-2 offer on the table is $70 an hour, which is $145,600 a year in wages plus 30% benefits ($43,680), for a total package of $189,280. To match the contractor's $88,088 take-home as a W-2 employee (who only pays 7.65% FICA), you would need a W-2 salary of roughly $95,385. The W-2 offer wins on total compensation, but the contractor can close the gap by raising their rate to $60–$65 or by deducting meaningful business expenses.
Example 2 — A senior specialist. A freelance consultant bills $150 an hour for 1,500 billable hours a year (the rest is sales and admin). Gross revenue is $225,000. After $12,000 of deductible business expenses and 15.3% SE tax, they net roughly $181,900, or about $121 an hour after tax. The equivalent W-2 salary needed to match that take-home is around $196,979 — and that ignores the fact that a W-2 role would also throw in benefits worth another $60,000 or so. This is why senior independent consultants often bill $150+ and still prefer contracting over a comparable staff job.
Example 3 — The beginner. A new contractor starts at $35 an hour, billing 2,080 hours. Gross is $72,800, SE tax is about $11,138, and net is $61,662 — roughly $29.65 an hour after self-employment tax. A W-2 offer at $45 an hour ($93,600 plus benefits) is a materially better deal at this stage. New contractors should either push their rate toward $50, plan to deduct real business expenses, or treat the first year as a rate-building investment rather than a long-term plan.
Example 4 — High-earning contractor. At $500 an hour for 2,080 hours, gross revenue crosses $1,040,000. Self-employment tax on the full amount is roughly $159,120, leaving about $880,880 net. The equivalent W-2 salary to match that take-home is near $953,849. Very high earners should note that the Social Security portion of SE tax has an annual wage-base cap (around $168,600 in recent years), so the effective rate above that cap drops — consult a CPA, because this calculator uses a flat 15.3% across all income.
FAQ
What is the self-employment tax rate?
The self-employment tax is 15.3% of your net self-employment earnings, split into 12.4% for Social Security and 2.9% for Medicare. In practice the IRS applies it to 92.35% of your net profit, which brings the effective rate to roughly 14.14%. You also get to deduct half of the SE tax when calculating your federal income tax. Use the 15.3% default in this calculator, or raise it to 25–30% if you want to estimate income tax on top.
How do I compare a 1099 rate to a W-2 salary?
Do not compare the two numbers directly. First, multiply your contractor rate by your billable hours to get annual gross revenue. Subtract deductible expenses and the self-employment tax to find your net take-home. Then compare that net figure to a W-2 salary after the employee's 7.65% FICA, and add the W-2 employer benefits (typically 25–35% of salary) on top. This calculator does both sides automatically.
What contractor hourly rate equals a $70,000 W-2 salary?
A W-2 salary of $70,000 costs the employer roughly $91,000 once benefits and the employer FICA match are added. To net the same amount as a W-2 employee on $70,000, a contractor needs to bill about $48–$52 an hour at 2,080 billable hours, after deducting business expenses. Use the Equivalent W-2 Salary output in reverse to pin down your exact rate.
Are contractor business expenses deductible?
Yes. Ordinary and necessary business expenses — software, equipment, professional liability insurance, home-office square footage, business travel, and mileage — are deducted on Schedule C before your net profit is taxed. Lower net profit means lower self-employment tax and lower income tax, so keep receipts and track mileage carefully. The Annual Business Expenses input on this page lowers your taxable contractor income by the amount you enter.
Do contractors pay into Social Security and Medicare?
Yes, through the self-employment tax. The 12.4% Social Security portion goes toward your future retirement benefits, and the 2.9% Medicare portion goes into the Medicare system. Earnings as a 1099 contractor count the same as W-2 wages for Social Security benefit calculations, so you are not "missing out" on credits — you are simply paying both the employee and employer halves yourself.
How much should I set aside for taxes as a contractor?
A widely used rule of thumb is to set aside 25–30% of every invoice for federal, state, and self-employment taxes. At very low profit levels the effective rate can be closer to 15–20%; at high earnings in a high-tax state it can approach 35%. Make quarterly estimated payments in April, June, September and January to avoid underpayment penalties.
What is the difference between a 1099 contractor and an employee?
A W-2 employee is on payroll: the employer withholds taxes, pays half of FICA, provides benefits, and controls how the work is done. A 1099 independent contractor runs their own business: they send invoices, pay the full 15.3% self-employment tax, buy their own benefits, and control how the work is performed. Misclassification carries legal risk for the client, so confirm your status with a tax professional before signing contracts.
