Pre Money vs Post Money Valuation Explained Simply

Pre money vs post money valuation explained: pre-money is what the business is valued at before the investment, post-money is that plus the investment. The investor's ownership is calculated on post-money. The gap between them is exactly the size of the round.

Pre money vs post money valuation explained in one sentence

They're two halves of one sentence. Pre-money is the value agreed before the investment. Post-money is that value plus the investment.

Done. That's the definition. It's elementary, and it gets fumbled in real conversations constantly.

Here's why pre money vs post money matters so much. Someone says "we're raising at ten". Ten what? Before the cash lands, or after? The difference between the two readings is the size of the round. Early on, the round is a big share of the business, so the difference is several points of your ownership.

Several points. From one unasked question.

The valuation is the headline of a deal, and it's the one number most reliably polished to look good. So the first job is to find out which headline you're reading.

Pre money vs post money, side by side

Keep one line from that table in your head. Investor ownership is calculated on post-money. Investment divided by post-money gives their share. Everyone else keeps the same proportion of a smaller share.

A way to feel the difference

Forget formulas for a moment. Think of it as a pie.

Pre-money is the pie before the investor sits down. Post-money is the pie after their cash has been added to it. The investor's slice is measured against the bigger pie, the post-money one.

Now see why it trips people up. A founder hears a big number and pictures the pie before. The investor hears the same number and may be thinking of the pie after. Same word, different pie. Nobody lied. Nobody checked.

So ask. Out loud. In the first minute. "Is that pre-money or post-money?" It takes five seconds and it can save several points of ownership. There is no polite way of avoiding it, so don't bother being polite.

Where the pool hides inside the gap

The pre-money number has a second use you need to know, and it's the one nobody mentions early.

When an option pool is created before the investment, it's taken out of the pre-money side. In effect, it comes out of the value the existing shareholders are credited with. That's how the same pool can cost you more or less depending on where it sits.

Investors typically propose the pool pre-money. It's normal and negotiable. But it means a headline pre-money figure and a pre-money figure after the pool are different things, and you should know which one you're being offered.

So when you read a valuation, ask two questions, not one. Pre or post? And is the pool already inside it, or on top? The mechanics are covered in what an option pool is and why it matters.

What this does to money you have already sold

If you've taken a SAFE or a note, the pre/post question has a cousin: the valuation cap.

The cap sets the maximum price at which that earlier money converts. It's the effective price for most instruments that end up in the money. The discount gives the holder a percentage off the round price instead.

Here's the catch. These convert into the priced round, and the round's valuation interacts with them. Several instruments on different caps all converting together can make a bigger block than the round. So the pre-money figure you're proud of may already be partly spoken for.

If you never took convertible money, nothing in this section touches you. It's a cost you simply don't carry. Remember that when someone tells you raising is the normal route.

The sanity check you can do in your head

You don't need a spreadsheet to catch the worst errors. You need the sequence.

1. Work out the investor's share: the investment divided by post-money.
2. Subtract that share from the whole.
3. Remember that you keep the same proportion of a smaller share.

If the headline implies a share you couldn't have guessed, you've probably misread pre and post. Stop and ask again.

When you're ready for the precise version, with the pool and the stack, how to calculate your ownership after a round walks through it. The instinct saves you in the room. The model saves you afterwards.

Why the headline is the least of it

Time for a hard truth. Even when you've nailed pre and post, you've only decoded the headline.

A term sheet has one number designed to be discussed and several designed to be accepted.

Two offers at the same valuation can produce very different results. What investors receive in an exit is governed by preference terms, not by ownership percentage. Who is paid first, how much, and whether they take their money back and then also share the rest are all separate from the valuation. In a great outcome these barely matter. In a mediocre one, which is the likeliest, they decide whether you receive a meaningful sum or practically nothing.

So treat pre and post as the literacy test, not the finish line. Start with what a liquidation preference is next.

Why the gap is biggest when you are small

The gap equals the round. So the smaller the business, the bigger a share of it that gap is.

For a mature company, a round is a rounding error against its value, and pre versus post barely registers. For an early or lean business, the cheque can be a large fraction of everything. That's why the question is nearly irrelevant to a big company and sharp for you.

It's also why a solo operator with real revenue and low costs can be fooled twice. Your business may be profitable and small. The round may be modest in absolute terms and still large against what you're worth on paper. The sentence "it's only a small cheque" tells you nothing until you've divided it by the right valuation.

Run both readings. If they land on very different ownership, you now know why the question matters and which one to insist on. If they land close together, relax and spend your attention on the pool and the preference instead.

Put your floor in writing first

Here's where this meets your walk-away. Before the first meeting, write down the minimum ownership you intend to hold after the round.

That number only means something if everyone is measuring it the same way. So define it on a basis you've confirmed: fully diluted, after the pool, after every instrument converts. Then test any valuation against it, pre or post, until you know which reading breaks your floor.

The version of you who writes the floor is rested and hasn't met anyone yet. The version of you who sees the term sheet is tired and likes the person across the table. Let the first one win.

A solo operator's habit for every offer

You own all of it today. That's your baseline, and it's a strong one. Any term sheet that arrives has to beat it, not just look flattering.

• Confirm whether the stated valuation is pre-money or post-money. Write the answer down.
• Find the pool size and which side of the money it sits on.
• List every instrument that converts because of the round.
• Model your ownership before you react.

No reaction to a term sheet, positive or negative, before the numbers are run. That protects you from the common error of falling for a flattering number. It also protects you from the opposite one: treating a fair offer as predatory because a clause sounds aggressive, when in your numbers it's immaterial. The routine is in how to model an investment offer before you respond.

Frequently asked questions

What is the difference between pre-money and post-money?

Pre-money is the value agreed before the investment. Post-money is that value plus the investment. The difference between the two is exactly the size of the round, and the investor's ownership is worked out on the post-money figure.

Which one should I ask about?

Both, immediately. When someone quotes a valuation, ask which it is, because pre money vs post money is the whole question. Then ask whether the option pool sits inside it. The wrong assumption can cost you several points of ownership.

Does a higher valuation always mean a better deal?

No. The valuation is the headline. Pool size and placement, preference terms and convertible instruments often move your outcome more. Judge an offer on all of it, not on the number that is easiest to discuss.

Do I need to know this if I may never raise?

Yes, a little. Pre money vs post money tells you exactly what you are protecting by owning all of it. If you ever do raise, you will not be the person discovering the gap the week after.
