Post-money valuation

Post-money valuation is a way of expressing the value of a company after an investment has been made. This value is equal to the sum of the pre-money valuation and the amount of new equity.^[1]

These valuations are used to express how much ownership external investors, such as venture capitalists and angel investors, receive when they make a cash injection into a company. The amount external investors invest into a company is equal to the company's post-money valuation multiplied by the fraction of the company those investors own after the investment. Equivalently, the implied post-money valuation is calculated as the dollar amount of investment divided by the equity stake gained in an investment.

More specifically, the post-money valuation of a financial investment deal is given by the formula ${\textstyle PMV=N\times P}$, where PMV is the post-money valuation, N is the number of shares the company has after the investment, and P is the price per share at which the investment was made. This formula is similar to the market capitalization formula used to express the value of public companies.
