Valuation Cap (Detailed explanation)

When calculating the percentage of equity that an investor will own as a result of an investment, valuation is the denominator. In the simplest version of this calculation, it’s “Dollars invested / value of company.” Such that if you invest $10k, and the company is worth $100k – the investor has purchased 10% of the company. Therefore, the valuation cap sets a maximum for the valuation of the company. Meaning that when running that same formula, there is a maximum, or cap, on how high it can be. Using the same example, let’s say the valuation cap is set to $200k, but your company is really worth $400k, when an investors’ note converts, their $10k investment will be worth $200k/$10k (which equals 5%), as compared to converting at $400k/$10k (which equals 2.5%). Essentially, it guarantees a certain percentage of ownership for the investor.
