Fill in the W-2 side with the salary number from your offer letter and — this is the part most people skip — the dollar value of your benefits package. Employer-paid health insurance commonly runs $7,000–$15,000/year. A 401(k) match is real money you'd otherwise have to fund yourself. Paid time off has a daily wage value (the tool converts your PTO days using a 260-workday baseline). Add dental, life, disability, and any other employer-paid perks under "other benefits". A $100k W-2 with a full benefits stack is often worth $115–$125k in total compensation.
Fill in the 1099 side with what a client would actually pay you for the same work. This number should be 25–50% higher than your W-2 equivalent — that's the standard 1099 premium that covers self-employment tax, self-funded benefits, and income volatility. Enter your annual deductible business expenses (Schedule C line items like software, equipment, professional fees, home office), the health insurance you'd buy on the marketplace, and what you'd contribute to a Solo 401(k) or SEP-IRA. Set the "unpaid time off" field to the days you plan to take off — you won't be paid for them, and the tool subtracts those hours from your effective hourly rate.
Pick your filing status to set the correct federal standard deduction and bracket widths. Enter your state tax rate as a single combined percentage (most states fall between 0–10%; zero out for no-tax states like Texas, Florida, Washington).
The result cards show total economic value for the W-2 side (cash take-home plus benefits) and cash take-home for the 1099 side (after SE tax, federal, state, self-paid health, and retirement). Use both effective hourly rates as a sanity check — they translate the comparison into work-time terms, which often clarifies tradeoffs the gross numbers obscure.
The "winner" badge highlights whichever side nets more in total economic value. Don't treat this as a final answer — autonomy, control over schedule, client risk, and income volatility don't show up in any tax line, but they matter as much as the dollars.
