You need three ideas, all explained in plain words here. All amounts on this page are in dollars, and "M" means million.
This page is one step of the investor pitch questions learning path. For more on the same topic, see valuation and dilution questions.
Why interviewers ask this
A founder who answers with one bare number invites the follow-up that exposes the gap: pre-money or post-money? One wrong word changes the ownership you are offering away. The same words can also be read a second way, as a finance candidate asked what a company is worth, and the second reading is covered in a variant below.
A weak answer states a figure and stops. A strong answer states the figure, names its basis, and says what ownership it implies for the investor. A Staff-level answer also shows that the number is a position in a negotiation: it admits what the number rests on and offers to work backwards from the ownership the investor needs.
Valuation from first principles
- Valuation
- A valuation is a price put on a whole company that a buyer and a seller agree to use for a deal, set by the latest price at which shares are sold, so it is a negotiated figure and not a quantity the company can simply measure.
- Post-money valuation
- A post-money valuation is the value of a company's equity after the round of financing has occurred, which equals the pre-money valuation plus the new money, and it is the base against which the investor's ownership percentage is measured.
- Valuation cap
- A valuation cap is the highest valuation at which a simple agreement for future equity (SAFE) converts into shares, so it limits the price an early investor pays when the later priced round happens.
In plain words
Imagine you sell a slice of a pizza business to a friend. You agree the whole business is worth a certain amount. Then the friend pays, and the slice is the payment divided by that amount. The analogy breaks in two places. A pizza shop has a price on the menu, while a young company has no menu, so the price comes from the negotiation. And in a funding round the cash goes into the company, not to you, which is why post-money equals pre-money plus the new money.
The friend pays cash, you hand over a slice, and both of you can check the fraction with simple division. In one precise sentence, a valuation turns a cash investment into a share of ownership. The fraction owned is the money in, divided by the company's value after the money is in.
Step 1: A valuation is a negotiated price, not a measured fact
A valuation is set by what investors will pay, so it moves with the market and the story. A public comment filed with the Securities and Exchange Commission (SEC) in 2013 puts it bluntly: "It is simply the price to buy the entire company, based on the latest price shares are sold at". The same letter gives the pre-money formula: shares outstanding before the offering times the price of a new share.
So the first sentence of your answer should treat the figure as a price. Say "we are raising at" a number, not "we are worth" a number. You now know what the number is. The next step is the one the investor checks first: what the number includes.
Step 2: Pre-money and post-money differ by exactly the new money
Post-money equals pre-money plus the new investment. Excedr defines pre-money as the equity value before the round and post-money as the value after it. Hustle Fund gives the same arithmetic: a 2M raise at an 18M pre-money valuation makes the post-money valuation 20M.1
The label matters because a headline number is ambiguous. Take a "10M valuation" on a 2M raise (illustrative). If it is post-money, the investor owns 2M divided by 10M, which is 20%. If it is pre-money, the post-money value is 12M and the investor owns 2M divided by 12M, which is 16.67%.1 The gap is 3.33 percentage points, a sixth of the investor's stake, and one word decides it.
Step-by-step description
- A valuation is a negotiated price.
- Post-money is pre-money plus new money.
- Ownership is investment over post-money.
- Pair the story with the numbers.
- A valuation is a negotiated price, not a measured fact.
- Post-money equals pre-money plus the new investment.
- Investor ownership equals the investment divided by the post-money valuation.
- A good valuation is a marriage between stories and numbers.
Step 3: Ownership is the investment divided by post-money
Investor ownership equals the investment divided by the post-money valuation. In the Hustle Fund example the investor puts in 2M at 20M post-money, so the investor owns 10% and the founders and earlier holders keep 90%.1
The price per share comes from the pre-money number. Pre-money divided by fully diluted shares gives the price per share, where fully diluted shares are every share that exists plus every share that options and similar rights could create. An option pool is a block of shares set aside for future employee stock options, and fully diluted shares include it. With 9,000,000 fully diluted shares (illustrative), 18M pre-money gives 2 dollars a share, the 2M buys 1,000,000 new shares, and 1,000,000 of 10,000,000 is 10%.1
| Reading | Investment | Post-money | Investor ownership |
|---|---|---|---|
| 10M valuation read as post-money | 2M | 10M | 20% |
| 10M valuation read as pre-money | 2M | 12M | 16.67% |
| 18M pre-money | 2M | 20M | 10% |
| SAFE with a 10M post-money cap (illustrative) | 0.5M | 10M | 5% |
A SAFE works the same way, with the cap in place of the round valuation. Y Combinator states that on a post-money SAFE, ownership sold equals the investment amount divided by the valuation cap, and that the post-money cap is "post" all the money raised on SAFEs but not the equity financing money.1
Text description of the diagram
- The investor owns 20% when 10M is post-money and 16.67% when 10M is pre-money.
- A 2M raise at 18M pre-money gives the investor 10%.
Step 4: Defend the number with a story and with numbers
Once the number and its label are clear, the investor tests why it is that number. Aswath Damodaran, speaking about young companies, says "A good valuation is a marriage between stories and numbers". A story with no numbers is a hope, and numbers with no story are guesses about a future nobody has described.
A discounted cash flow (DCF) is a method that adds up the future cash a company is expected to produce, reduced to today's value. A young company may not survive, so a model of this kind has to allow for failure.
A practical way to keep the talk on firm ground is to anchor on the round size and the ownership you will sell, then give the evidence for the price, such as traction and market. The metrics deep-dive shows how investors test traction, and why now and why you covers the story behind it. That moves the discussion from one number to dilution, the fall in your percentage when new shares are issued.
Knowing it is half the job. Saying it is the other half.

Start Free Trial →The Staff-level answer
What is your valuation?
We are raising 2M at an 18M pre-money valuation, so the post-money valuation is 20M and your 2M buys 10% of the company. I am giving you the pre-money number because it sets the price per share, and I want us to use the same definition. I treat 18M as a price rather than a measured fact: it reflects our traction, our market and the story that traction supports. If you see it differently, tell me the ownership you need and I will work backwards to the round size. If an option pool is part of the deal, I want it counted explicitly in that pre-money number.
The numbers in that answer are illustrative and computed in the data script.1 What makes it Staff-level is the second sentence and the last three: they label the number, admit what the number rests on, and turn a standoff about one figure into a conversation about ownership.
The rubric
| Dimension | Weak answer | Strong answer | Staff answer |
|---|---|---|---|
| Correctness | A single number with no label | Number labelled pre-money or post-money | Labels the number and states the price per share it implies |
| Depth | "We are worth that much" | Converts the number to investor ownership | Names the share count and any option pool inside the number |
| Trade-offs | Defends the highest figure | Acknowledges the number is negotiable | Weighs a higher price against terms and the next round |
| Communication | Long, defensive | Short, with the round size and stake | Invites the investor's target ownership and works backwards |
| Follow-up readiness | Surprised by "pre or post?" | Answers it at once | Has already raised it and moved on |
Three variants of this question
What is your valuation if you are raising on a SAFE?
You give the valuation cap and say it is post-money. On a post-money SAFE, ownership sold is the investment divided by the cap, so a 0.5M investment at a 10M cap (illustrative) is 5%.1 Add that the post-money cap counts all SAFE money but not the money of the later equity round.
Is that pre-money or post-money?
Say which one and give the other: "18M pre-money, 20M post-money, 2M raised." Then state the ownership, 10%. Answering both numbers in one sentence removes the follow-up.
What is your valuation of this company?
Asked of a finance candidate, the question usually means what a company is worth, not what a round prices it at. A strong answer names the method, such as comparable companies (valuing the company from the prices of similar listed companies), precedent transactions (valuing it from the prices paid when similar companies were bought) or a DCF, says what each assumes, and gives a range with the reasoning. It then says which method it weights most and why, and what would move the range, such as the growth rate or the discount rate. A DCF assumes the company keeps operating, so a young company's model must allow for failure.
Common mistakes
- "Our valuation is 10M." (wrong) The label is missing. (right) "10M post-money, so 2M buys 20%."
- "The valuation is whatever the spreadsheet says." (wrong) A valuation is a negotiated price, and the SEC comment letter defines it by the latest share price. (right) "That is the price we are asking for, and here is the evidence."
- "Pre-money and post-money are the same number." (wrong) They differ by exactly the new money, which changes the stake. (right) "Post-money is pre-money plus the raise."
- "The SAFE cap includes the next round's money." (wrong) Y Combinator says the post-money cap is not "post" the equity financing money. (right) "The cap counts all SAFE money only."
Follow-up questions
What if the investor offers a lower valuation?
Convert both offers to ownership and compare the terms, not only the headline number. A higher valuation is not automatically the better offer, because price is only one of the terms; the term-sheet negotiation scripts show how to talk through the others.
Does the option pool change the valuation?
An option pool created inside the pre-money changes the effective price for existing holders, even though the headline pre-money stays at 12M. In an illustrative round of 3M at 12M pre-money, a pool of 15% of the post-money value (2.25M) cuts the effective pre-money to 9.75M, so existing holders own 65% against the investor's 20% and the pool's 15%.1
What happens if the company later raises at a lower price?
The valuation is set by the latest share price, so a lower price resets the company's valuation to that price. The company issues more shares per dollar raised, so earlier holders are diluted more, by an amount that also depends on any anti-dilution terms they negotiated. The SEC comment letter defines the figure by the latest price at which shares are sold.
- A valuation is a negotiated price set by the latest share price, not a measured fact.
- Always say pre-money or post-money; post-money is pre-money plus the new money.
- Investor ownership equals the investment divided by the post-money valuation.
- On a post-money SAFE, ownership equals the investment divided by the valuation cap.
- Defend the number with a story and numbers, then offer to work backwards from the ownership.
