Notes:
1. Terminal Value (at time of exit)
2. Number of existing shares (owned by the entrepreneurs)
3. Valuation of company at the time of event (financing or exit)
4. The compound discount rate (1+R) is the product of the discount rates (1+r) between the time of two valuation events
5. Amount of investment per round
6. Number of existing shares (prior to financing event)
7. Post-Money Valuation: POST = V/(1+R)
8. Pre-Money Valuation: PRE = POST - I
9. Required ownership fraction for the investor: F = I / POST
10. Number of shares the investors require to achieve their desired ownership fraction: y = x[F/(1-F)]
11. Price per share: p = I / y
12. Discount rates per year. For calculating the compound discount rate (1+R).
13. Use the product of the discount rates (1+r) to calculate the compound discount rates (1+R) used in [4].
