Pre-money

Full name: Pre-money Valuation

Also known as: pre-money valuation, pre money valuation, initial valuation

Definition

The valuation of a company before it receives a new round of investment.

The agreed-upon value of a startup prior to the investment of new capital in a funding round, used to determine the price per share.

Why it matters

Pre-money valuation determines how much equity a founder must give up to secure a specific amount of capital. For example, if a company has a pre-money valuation of $4,000,000 and raises $1,000,000, the investors will own 20 percent of the company after the round.

Formula

Pre-money Valuation = Post-money Valuation - Investment Amount

Improvement tips

  • Negotiate pre-money valuation based on current traction and market comparables.
  • Understand that a higher valuation is not always better if it sets unrealistic expectations for future rounds.
  • Model how the option pool expansion will impact your pre-money share price.

Common mistakes

  • Confusing pre-money valuation with post-money valuation when negotiating terms.
  • Failing to account for the dilutive effect of the option pool when it is included in the pre-money valuation.
  • Focusing solely on the valuation number rather than the overall terms of the deal.

Frequently asked questions

Do I need to set a pre-money valuation before I launch my startup?
No, early startups often raise money using SAFEs or convertible notes to avoid setting a pre-money valuation before they have revenue. You only need to set one when running a priced equity round.
When does pre-money valuation first become a factor in negotiation?
It becomes a factor when you are negotiating a priced investment round with a lead investor. It is the agreed value of your company before the new investment cash is added.
Can I determine my startup's pre-money valuation using standard formulas?
No, early-stage valuation is more of an art than a science. It is determined through negotiation based on your team, market size, prototype quality, and any early traction you have achieved.
How does pre-money valuation affect the equity I give to early investors?
A higher pre-money valuation means you give up less equity for the same amount of investment capital. For example, if your pre-money valuation is four million dollars and you raise one million, investors will own twenty percent.
Why does pre-money valuation matter for a business raising a new round?
It directly determines the dilution that existing shareholders will experience. Negotiating a fair pre-money valuation protects your ownership percentage while securing the capital needed to grow.
How do I calculate pre-money valuation from my post-money term sheet?
You subtract the new investment amount from the post-money valuation. It is a simple calculation that ensures you know the starting value of the business before the cash is deposited.
What goes wrong when an operator accepts an unrealistically high pre-money valuation?
It sets expectations too high for your next round, which can lead to a down round if you do not reach your growth targets. A down round can damage company morale and investor relationships.
How does the option pool expansion affect my pre-money share price?
If investors require you to create or expand the option pool within the pre-money valuation, it will reduce your share price and increase founder dilution. You should negotiate this point carefully.
What is pre-money valuation in plain language?
Pre-money valuation is the agreed value of your company before any new investment money is added to the bank account. It is the price tag of your business before a funding round.
Is calculating pre-money valuation risky or complicated?
The calculation itself is very simple subtraction. The only challenge is negotiating the valuation with investors, which can feel intimidating but is a normal part of business.
Do I need a certified appraiser to set my pre-money valuation?
No, you do not need an appraiser. Startup valuations are agreed upon through negotiation between the founders and the investors based on market conditions.
Will setting a pre-money valuation cost my business cash?
No, setting a pre-money valuation is just an agreed negotiation step and does not cost any cash. It only requires a discussion between the founders and the investors to agree on the starting value.
