Valuing your shares

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.

One catch: the last-round price is usually for preferred shares. If you hold ordinary common shares or options, yours are worth somewhat less than that headline price, because preferred carries protections common doesn't.

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?
