Stop Guessing.
Know Which Offer Wins.
The average person leaves $10,000–$30,000 on the table by not properly comparing offers or negotiating. OfferDuel shows you the real numbers — after taxes, cost of living, equity, benefits, and commute costs — then writes your negotiation email.

What Makes This Different
Most salary comparison tools just show base salary. OfferDuel calculates what you actually take home.
50-State Tax Engine
Real federal + state bracket calculations with standard deductions, FICA, Medicare surtax. Not estimates — real math.
Cost of Living Adjustment
$150K in San Francisco ≠ $150K in Austin. We adjust your after-tax income by real COL indices.
Equity Valuation
RSUs vs options. Vesting schedules. Strike prices. We annualize the real value — not the inflated 4-year number.
Benefits Calculator
401k match value, health insurance costs, PTO dollar value. The invisible $10K-30K most people ignore.
Commute Impact
45 min commute = 390 hours/year = $19K opportunity cost at $100K salary. We quantify it.
Negotiation Scripts
Professional counter-offer emails backed by your specific numbers. Not generic templates — your data, your ask.
