Pre-Money and Post-Money Valuation Explained

Few terms create more confusion in an investment round than pre-money and post-money valuation — yet the difference is simple once you've seen it explained with numbers.

Short answer: Pre-money valuation is the business's value before the investment is added. Post-money valuation is the value after: pre-money value plus the new investment amount. The difference determines how large an equity stake the investor gets — which is why it's one of the very first numbers you need to agree on in the term sheet.

A concrete example

Say you agree the business is worth DKK 8m before the investment — that's the pre-money valuation. An investor puts in DKK 2m. The post-money valuation then becomes 8 + 2 = DKK 10m. The investor's equity stake is calculated as investment amount divided by post-money valuation: 2m / 10m = 20%.

Why the confusion happens

The problem typically arises when an investor says "I value the business at DKK 10m" — without specifying whether that's before or after their own contribution. If the DKK 10m is post-money, the investor gets 20% (as in the example above). If the DKK 10m is instead pre-money, the post-money value becomes DKK 12m instead, and the investor's stake drops to 2/12 ≈ 16.7%. Same investment amount, same "DKK 10m" figure — but two different equity stakes. Always ask explicitly: "Is that pre- or post-money?"

Why it ties Investor, Valuation and M&A together

The exact same valuation principle applies whether you're seeking an investor or planning a future sale of the entire business. The more precise and well-documented your starting point for the valuation is, the easier it is to negotiate a fair pre-money value — and therefore a fair equity stake for the investor.

How to use it in practice

Always write "pre-money" or "post-money" explicitly next to any valuation figure you discuss — in emails, meetings, and the final term sheet alike. It sounds trivial, but it's one of the most common sources of misunderstanding in early-stage investment negotiations.
