Understanding Startup Equity: What Its Really Worth
The Real Value of Startup Equity
A startup offers you $150,000 salary plus equity worth “$400,000.” A larger company offers $220,000 with smaller RSU grants. Which is the better deal? The answer is more complex than it appears—and getting it wrong can cost you hundreds of thousands of dollars.
Startup equity is potentially valuable but frequently misunderstood. Here’s what you need to know to evaluate equity offers accurately.
Equity Basics
Types of Startup Equity
Stock Options (ISOs and NSOs):
- The right to buy shares at a set price (strike price)
- You pay the strike price to “exercise” options
- Value depends on future price exceeding strike price
- ISOs (Incentive Stock Options) have tax advantages
- NSOs (Non-Qualified Stock Options) are simpler but taxed as income
Restricted Stock Units (RSUs):
- Promise of shares delivered on vesting
- No purchase required
- More common at later-stage startups and public companies
- Taxed as income when vested
Vesting
Equity typically vests over time:
- Standard schedule: 4-year vesting with 1-year cliff
- Cliff: No equity until 1 year, then 25% vests at once
- Monthly vesting: Remaining 75% vests monthly over 3 years
- Implications: Leave before the cliff = no equity; leave at 2 years = 50% vested
Valuation Terminology
- 409A valuation: IRS-compliant valuation for setting option strike prices
- Last funding round valuation: What investors paid for preferred shares
- Fully diluted shares: Total shares including all options and future dilution
- Preferred shares: What investors hold; includes liquidation preferences
- Common shares: What employees typically receive
Evaluating Equity Offers
Key Questions to Ask
- How many shares? The number of shares matters less than percentage
- What’s the total fully-diluted share count? Allows you to calculate your percentage
- What’s the current 409A/strike price? Your cost to exercise options
- What was the last funding round valuation? Context for company value
- What’s the vesting schedule? When you actually own equity
- What’s the option exercise window post-departure? Time to exercise after leaving
Calculating Percentage Ownership
Example: Offered 10,000 shares, fully-diluted count is 10,000,000
Your ownership: 10,000 / 10,000,000 = 0.1%
This percentage will dilute in future funding rounds.
The Discount for Illiquidity and Risk
Startup equity isn’t cash. Apply substantial discounts:
- Illiquidity: You can’t sell until an exit event
- Risk: Most startups fail or have modest exits
- Time value: Money now is worth more than money maybe later
- Dilution: Future rounds will reduce your percentage
- Liquidation preferences: Investors get paid first in exits
Rule of thumb: Apply 80-90% discount to paper value for early startups.
Common Equity Traps
The “Value” Fallacy
Company states equity is “worth $400,000” based on last round valuation. Issues:
- That’s preferred share price; your common shares are worth less
- You can’t sell at that price
- The company may never achieve that value in an exit
- Dilution will reduce your percentage
Short Exercise Windows
Standard is 90 days to exercise after leaving. Problems:
- May require tens of thousands of dollars to exercise
- Creates tax liability on exercise
- Essentially forces you to stay or lose equity
Some companies offer extended exercise windows (10 years); negotiate for this.
Underwater Options
If the company’s value drops below your strike price:
- Your options are worthless until value recovers
- Common after down rounds or market corrections
- Company may offer refresher grants, but not guaranteed
Phantom Equity
Some startups offer:
- Profit sharing (depends on profits that may never materialize)
- Appreciation rights (complex structures)
- Delayed grant promises (may never be formalized)
Ensure you get actual equity, documented properly.
Stage-Specific Considerations
Early Stage (Pre-Seed, Seed)
- Higher risk, potentially higher reward
- Larger percentages offered (0.1%-1%+ for early engineers)
- Most likely to fail
- Longest time to liquidity (7-10+ years)
- Most dilution ahead
Growth Stage (Series B-D)
- More proven business, lower risk
- Smaller percentages (0.01%-0.1%)
- Higher valuations mean more potential value per percentage
- Path to exit more visible
- Less dilution ahead
Late Stage (Pre-IPO)
- Closest to liquidity
- RSUs more common than options
- Lower upside but more certain value
- May have secondary market opportunities
Negotiating Equity
What’s Negotiable
- Number of shares/options: Often flexible
- Strike price: Usually not (determined by 409A)
- Vesting schedule: Sometimes (cliff length, acceleration)
- Exercise window: Worth asking for extension
How to Negotiate
- Research comparable offers at similar stage companies
- Ask for percentage, not just share count
- Request extended exercise window
- Consider accelerated vesting on acquisition
- Get everything in writing
When to Value Cash Over Equity
Consider prioritizing cash when:
- You need income for financial obligations
- The startup has high risk factors
- The equity offer is small relative to cash gap
- You’ve already had several equity-heavy roles
- The company culture or leadership raises concerns
Tracking and Managing Equity
Documentation to Keep
- Original offer letter
- Stock option agreement
- 409A valuation at grant time
- Vesting schedule confirmation
- Any equity refresh grants
Decisions to Make
- Early exercise: Sometimes beneficial for tax purposes
- 83(b) election: Must file within 30 days if early exercising
- Exercise strategy: When/whether to exercise vested options
Consult a tax advisor for your specific situation.
The Bottom Line
Startup equity is a lottery ticket with potentially life-changing upside—but most tickets don’t pay out. Evaluate equity offers skeptically, understand what you’re actually receiving, and don’t sacrifice cash you need for speculative upside you might never see.
The best approach: take equity at companies you believe in, with business models that make sense, led by people you trust. Accept lower cash when you can afford to and when the upside potential justifies the risk. Otherwise, prioritize guaranteed compensation.
