See what your startup investment could become

Every time a startup raises money, your share of it shrinks. See what following on would cost, and what your stake could return when the company sells.

Run your own numbers

Enter your first cheque, add the rounds the company raises, and decide at each one whether you follow on. Nothing you type leaves your browser.

Future funding rounds

Each time the company raises money it issues new shares, so your percentage falls unless you invest again. For each round, choose whether to use your pro-rata right.

No later rounds yet. Add a Series A to see how new money dilutes you and what it would cost to keep your share.

The maths, briefly

How a small stake grows, shrinks and pays out

Four ideas decide what your cheque returns. Each is worked through with one example, €5,000 into a Pre-seed round, using the same engine as the calculator.

Equity: what your cheque buys

You invest €5,000 in a Pre-seed round: €4M pre-money, raising €1M.

  1. 1Post-money valuation

    €4,000,000 + €1,000,000 =€5,000,000

  2. 2Your ownership

    €5,000 ÷ €5,000,000 =0.10%

Pre-money is the company’s value before the round; post-money adds the new money. Your ownership is always your cheque divided by post-money.

Dilution: why your percentage falls

The Seed raises €3M at a €15M post-money valuation, and you don’t invest.

  1. 1Share of the company sold

    €3,000,000 ÷ €15,000,000 =20%

  2. 2Share of your stake you keep

    100% − 20% =80%

  3. 3Your new ownership

    0.10% × 80% =0.080%

  4. 4Your paper value

    0.080% × €15,000,000 =€12,000

Your percentage fell, yet your paper value rose from €5,000 to €12,000, because the company grew faster than it diluted you.

Pro-rata: what it costs to keep your share

To stay at 0.10% through the Seed, you buy your share of the new money.

  1. 1Pro-rata cheque

    0.10% × €3,000,000 =€3,000

  2. 2Ownership after investing

    0.080% + (€3,000 ÷ €15,000,000) =0.10%

  3. 3Your paper value

    0.10% × €15,000,000 =€15,000

Investing €3,000 more lifts your paper value from €12,000 to €15,000. Skip it and your share falls to 0.080%.

Exit: what your stake could return

You sit out every later round and the company sells for €250M.

  1. 1Ownership after Seed, Series A and Series B

    0.10% × 80% × 80% × 80% =0.0512%

  2. 2Your proceeds

    0.0512% × €250,000,000 =€128,000

  3. 3Your multiple

    €128,000 ÷ €5,000 =25.6×

  4. 4After 20% carry

    €128,000 − 20% × (€128,000 − €5,000) =€103,400 · 20.7×

Near or below the €32M the company raised, liquidation preferences pay later investors first, so you can receive less than your percentage suggests.
