What is {primary_keyword}?
The {primary_keyword} is a specialized financial tool used by early‑stage startups to model the impact of a draft trade—typically a seed or Series A investment—on ownership percentages, valuation, and option pool size. Entrepreneurs, founders, and investors use it to understand how much equity the founder will retain after the round and how the option pool will be affected.
Anyone planning a financing round, negotiating term sheets, or advising startups should be familiar with the {primary_keyword}. It helps avoid surprise dilution and ensures that the option pool is sufficient for future hires.
Common misconceptions include assuming that the investor’s share equals the dilution percentage or that the option pool does not affect founder ownership. The {primary_keyword} clarifies these points by separating investment dilution from option pool adjustments.
{primary_keyword} Formula and Mathematical Explanation
The core formula calculates founder dilution based on the investor’s cash contribution and the post‑money valuation:
Founder Dilution (%) = (Investor Investment ÷ Post‑Money Valuation) × 100
From this, the pre‑money valuation is derived as:
Pre‑Money Valuation = Post‑Money Valuation – Investor Investment
The option pool after trade is simply the user‑entered increase percentage.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Post‑Money Valuation | Total company value after investment | Millions | 1 – 100 |
| Investor Investment | Cash contributed by the investor | Millions | 0.1 – 20 |
| Option Pool Increase | Additional option pool percentage | Percent | 0 – 20 |
| Founder Dilution | Equity percentage lost by founders | Percent | 0 – 100 |
| Pre‑Money Valuation | Company value before investment | Millions | 0 – 100 |
Practical Examples (Real‑World Use Cases)
Example 1
Company A raises $2 M at a post‑money valuation of $10 M and adds a 5 % option pool.
- Pre‑Money Valuation = 10 – 2 = $8 M
- Founder Dilution = (2 ÷ 10) × 100 = 20 %
- Option Pool After Trade = 5 %
Result: Founders retain 80 % of the equity before accounting for the option pool.
Example 2
Company B secures $5 M with a post‑money valuation of $25 M and creates a 10 % option pool.
- Pre‑Money Valuation = 25 – 5 = $20 M
- Founder Dilution = (5 ÷ 25) × 100 = 20 %
- Option Pool After Trade = 10 %
Result: Founders keep 80 % of the equity, but the effective ownership after the option pool is 70 %.
