Q: Should I prioritize salary or equity at a startup?

It depends on your financial situation and risk tolerance. Salary-heavy offers (≥70% salary) are better for short-term stability , while equity-heavy offers (≤50% equity) have higher upside but carry risk . Consider your savings runway, ability to absorb losses, and belief in the company's trajectory.

Q: How do I value equity in pre-revenue companies?

For pre-revenue companies, the calculator uses the latest 409A valuation (typically set at $10–$50M for seed-stage startups) and applies conservative multipliers (0.5–1.0x). Early-stage equity is highly speculative; these estimates have wide confidence intervals.

Q: How do I compare offers from private companies vs. public companies?

Public company equity (RSUs) is more liquid and less risky, typically valued at current share price. Private company equity (options/RSUs) is illiquid and depends on a future liquidity event. This calculator is optimized for private companies; for public companies, consider using current fair market value instead of estimated outcomes.

Q: What’s the biggest mistake engineers make when evaluating equity?

The most common pitfall is overestimating equity potential . Many engineers focus on the number of shares instead of ownership percentage and exit multiples . For example, 10,000 options at a $50M valuation is worth less than 1,000 options at a $500M valuation—even if 10,000 shares feels more valuable. Always analyze equity in context of company stage and funding.

Question 1

How accurate are these equity estimates?

Accepted Answer

Equity estimates are highly variable based on company stage, funding conditions, and market sentiment. This calculator uses venture capital return multiples and public market comparables to project likely outcomes, but actual equity value can range from $0 to 5x+ of the estimate. Always verify grant details with your recruiter or hiring manager.

Question 2

Should I prioritize salary or equity at a startup?

Accepted Answer

It depends on your financial situation and risk tolerance. Salary-heavy offers (≥70% salary) are better for short-term stability, while equity-heavy offers (≤50% equity) have higher upside but carry risk. Consider your savings runway, ability to absorb losses, and belief in the company's trajectory.

Question 3

How does company performance affect equity value?

Accepted Answer

The calculator uses exit multiples based on venture capital return profiles:
- Poor performance (0.5x): down round, equity worth ~50% of grant value
- Steady (1.0x): no change, equity equals grant value
- Good (1.5x): likely acquisition/IPO, 1.5x grant value
- Exceptional (2.0x+): top-tier unicorn, 2x+ grant value
These multipliers approximate real-world outcomes observed in PitchBook and CB Insights startup exit data.

Question 4

What tax rate should I use for equity compensation?

Accepted Answer

Equity taxation depends on the type (ISOs vs. NSOs) and holding period. This calculator uses a 35% flat rate as an estimate for short-term capital gains. Actual rates may be lower for qualified dispositions (20%) or higher if combined with other income. Consult a tax professional for your specific situation.

Question 5

How do I value equity in pre-revenue companies?

Accepted Answer

For pre-revenue companies, the calculator uses the latest 409A valuation (typically set at $10–$50M for seed-stage startups) and applies conservative multipliers (0.5–1.0x). Early-stage equity is highly speculative; these estimates have wide confidence intervals.

Question 6

Does this calculator account for dilution?

Accepted Answer

No. The tool assumes your ownership percentage stays constant, but startups often dilute 5–10% per funding round. Later-stage equity (Series C+) is less affected than early-stage (seed/Series A). Factor this into long-term projections.

Question 7

How do I compare offers from private companies vs. public companies?

Accepted Answer

Public company equity (RSUs) is more liquid and less risky, typically valued at current share price. Private company equity (options/RSUs) is illiquid and depends on a future liquidity event. This calculator is optimized for private companies; for public companies, consider using current fair market value instead of estimated outcomes.

Question 8
