What Is a Contractor Rate To Salary Calculator?
A contractor rate to salary calculator estimates what an hourly contract rate is worth when compared with a W-2 salary. The simple calculation is hourly rate times billable hours, but that number can overstate the practical value of a contract offer. Contractors often cover their own benefits, insurance, software, equipment, unpaid vacation, and tax administration.
This calculator separates gross contract revenue from an estimated salary equivalent. It starts with your billable schedule, subtracts annual business expenses and replacement benefits, then estimates the extra self-employment tax burden compared with a simplified W-2 employee FICA share.
How to Calculate Contractor Rate to Salary
First, multiply contractor hourly rate by billable hours per week and billable weeks per year. That gives annual contract revenue. Next, subtract ordinary business expenses and the value of benefits you need to replace. Finally, account for the extra payroll-tax burden that self-employed workers often carry.
The IRS self-employment tax rate is commonly summarized as 15.3%, and IRS Topic 554 explains that generally 92.35% of net self-employment earnings are subject to that tax. This page uses those figures as a simplified planning model, not as a tax filing result.
Worked Examples
$95/hr for 32 hours and 46 weeks
Annual billable hours equal 1,472. Gross contract revenue is $139,840. After $9,000 in expenses, $18,000 in replacement benefits, and estimated extra self-employment tax burden, the W-2 equivalent is much lower than the headline contract gross.
Targeting a $120,000 W-2 salary
If you want the contract to feel like a $120,000 salary, you need to cover the target salary, annual expenses, benefit replacement, and tax burden across your expected billable hours. The breakeven hourly rate card estimates that required contractor rate.
When This Estimate Is Useful
Use this calculator before accepting a 1099 offer, converting from employee to contractor, quoting a consulting engagement, or comparing two compensation structures. It is especially useful when a contract rate sounds high but the project includes unpaid downtime, no benefits, or meaningful operating costs.

Frequently Asked Questions
How do you convert a contractor hourly rate to salary?
Multiply contractor hourly rate by billable hours per week and billable weeks per year to estimate gross contract revenue. Then adjust for business expenses, replacement benefits, unpaid downtime, and extra self-employment tax burden to estimate a W-2 salary equivalent.
Why is contractor gross revenue not the same as salary?
Contractor gross revenue often has to cover unpaid time, software, insurance, equipment, health insurance, retirement contributions, and the employer side of payroll taxes that a W-2 employer may otherwise cover.
What self-employment tax rate does this calculator use?
It uses a simplified IRS-based planning estimate: 15.3% self-employment tax applied to 92.35% of net self-employment earnings after business expenses. Exact tax results depend on current law and personal facts.
What should I enter for benefits replacement?
Enter the annual cost or value you need to replace employer benefits, such as health insurance, retirement match, paid time off, disability insurance, equipment, training, or other compensation value.
How do I calculate the contractor rate needed to match a salary?
Start with the target W-2 salary, add annual business expenses and benefits replacement, then divide by annual billable hours after allowing for extra self-employment tax burden. This page estimates that breakeven hourly rate.
Should I use 2,080 hours for contractor work?
Use 2,080 only if you truly bill 40 hours every week for 52 weeks. Contractors often bill fewer hours because of unpaid time off, sales time, admin work, holidays, and gaps between projects.
Does this calculator decide whether I am a contractor or employee?
No. Worker classification depends on legal and factual tests. This page is only a compensation planning calculator and does not determine employment status.
Does this calculator show take-home pay?
No. It estimates gross salary-equivalent value before income tax, state tax, deductions, credits, and exact payroll withholding. Use a tax or paycheck calculator for net pay planning.
