Why a salary cannot be converted to a contractor rate with one fixed multiplier
Rules such as “add 20%” or “divide salary by 2,000 and add 30%” are shortcuts. They can be useful for a quick conversation, but they do not solve the actual financial comparison. A W-2 employee and a 1099 contractor can have different payroll-tax treatment, state-tax results, health-insurance costs, business expenses and paid-versus-unpaid time. The audited calculator therefore compares estimated take-home instead of applying one universal premium to gross salary.
The solver begins with the selected W-2 salary and state, calculates the W-2 estimated take-home, and then searches for the contractor gross that produces approximately the same net amount under the 1099 path. That annual result is the break-even gross. It is a planning floor, not a guaranteed market rate or negotiation recommendation.
How $80k, $100k, $120k and $150k scenarios differ
The required contractor premium does not stay perfectly constant as salary increases because federal brackets, payroll-tax limits, deductions and state rules can interact with income. The same W-2 salary can also require a different 1099 target in different states. Use the salary buttons above as starting points, then enter your actual state, expenses and health-insurance cost rather than treating a published example as your personal result.
For higher contractor revenue, also pay attention to the assumptions documented by the product. The current model is a planning tool with a defined tax scope, not tax-preparation software. More complex filing situations can require professional analysis outside the calculator.
Convert annual break-even into an hourly contractor rate
Hourly conversion should use realistic billable hours. A contractor billing 2,000 hours has a lower hourly break-even than someone billing 1,500 hours because the same annual target must be earned in fewer revenue-producing hours. Vacation, holidays, sick time, training, administration, sales and gaps between contracts can all reduce utilization. Test several hour assumptions before deciding what hourly rate you need to ask for.
What to do after you find break-even
If the current offer is below break-even, use the counter-offer output as the minimum amount required to reach the modeled W-2 net target. If it is above break-even, evaluate the remaining difference against benefits you would lose, contract risk and the profit margin you want from independent work. The financial floor and the rate you choose to negotiate are related, but they are not necessarily the same number.
