How much are my startup shares worth?
There's no live share price for a private company — but you can get to a realistic figure with two numbers you already have. Here's how, and where people go wrong.
If you hold shares or options in a private startup, "what are they worth?" has no official answer the way a listed stock does. There's no market ticking away. But you're not in the dark either — a sensible estimate comes from two things: a reference price per share and how many shares you hold.
Step 1 — find a reference price per share
The usual reference is your company's last funding round — the price per share investors paid. You'll find it on your term sheet, your share or option agreement, or the cap table. If there's been no recent round, a 409A valuation (or your country's equivalent) or the latest company valuation is the next-best anchor.
Step 2 — multiply by what you hold
Reference price per share × your number of shares = a rough paper value. If you hold options rather than shares, remember you'd first pay the exercise price to own the shares — so your net position is the paper value minus the cost to exercise (and any tax).
Step 3 — adjust to a realistic sale price
Paper value isn't what a buyer pays today. A private, minority, all-cash sale happens at a discount to that headline number — for illiquidity, for selling common rather than preferred, and for the buyer's information risk. So your realistic sale figure is the paper value, minus that discount.
How big a discount is its own question — we cover it in what discount is fair when you sell startup shares?
Where people go wrong
- Using the headline valuation for common shares. Your common shares or options are worth less than the preferred price.
- Forgetting dilution. Later funding rounds issue new shares, so your percentage — and sometimes your per-share value — can change.
- Ignoring the exercise cost. Options aren't free to turn into shares; net value is what matters.
- Confusing paper value with cash. The number on the cap table is not what lands in your account after a discounted, taxed sale.
