Educational use only

The calculators, guides and salary data on BiotechFIRE are general information to help you understand how equity compensation and personal finance work. They don't take your full situation into account and are not a recommendation to buy, sell, hold or exercise any security, or to take any tax position.

Estimates, not answers

• Tax estimates use 2026 US federal parameters (IRS Rev. Proc. 2025-32), a single flat state rate you enter and the standard deduction.
• They leave out many things that can change your result, including state AMT, the AMT credit, itemized deductions, other income and losses, phase-outs, local taxes, and your company's specific plan rules.
• Vesting schedules, scenario values and offer comparisons depend entirely on the numbers you enter. Outcomes, odds and prices are assumptions, not predictions.
• Salary data comes from anonymous self-reported submissions. We review entries but can't verify them.

Talk to a professional

Before you exercise options, sell company stock, choose between job offers or make other significant financial decisions, talk to a qualified tax professional, financial planner or attorney who knows your situation.

No warranty

We work hard to keep the tools accurate, but they're provided "as is," without warranties of any kind. Tax law changes, and errors happen. To the fullest extent the law allows, BiotechFIRE isn't liable for decisions you make or losses you incur based on the site.

Insider trading and company policies

Nothing here overrides your company's insider trading policy, blackout windows or pre-clearance requirements. Ticker symbols and fund names are examples, not recommendations.
