Post-money valuation

As explained in Tech Startup Toolkit

A post-money valuation is the value assigned to a company immediately after a new investment, including the invested cash.

Post-money valuation is the value assigned to a company immediately after a new investment. It includes the cash just added to the company’s balance sheet. section 10.4

Keep these practical points in mind when reviewing a seed financing:

  • Calculate post-money valuation by adding the investment to the pre-money valuation. section 10.4
  • Treat the valuation as an investor’s judgment, often based on the team, intellectual property, comparable companies, and product stage. section 10.4
  • View post-money valuation as a hoped-for floor, not a guarantee: stalled customer acquisition, product failure, or leadership loss can reduce it. section 10.4

A simple seed-round calculation

Suppose investors assign a $1.5 million pre-money valuation and invest $1 million. The post-money valuation is $2.5 million: $1.5 million plus $1 million. At this stage, investors may seek roughly 30% to 40% ownership because the risk is high. section 10.4

How Tech Startup Toolkit covers it

How deep it goes
Defines the calculation, gives a seed example, and qualifies the valuation as a fallible floor rather than explaining detailed pricing mechanics.
Examples
Uses a $1.5 million pre-money valuation, $1 million investment, 30%–40% investor ownership, and a seed-to-Series-A comparison figure.
What it assumes
Assumes a startup seed-financing context while teaching pre-money and post-money valuation terminology directly.
What you can do after
Evaluate/understand a seed investment’s immediate company value by adding the investment to the pre-money valuation.
How it connects
Connects post-money valuation to pre-money valuation, seed financing, and Series A.
