Pre-money valuation is the agreed value of a company immediately before a financing round, not counting the new capital. It sets the price per share: pre-money valuation divided by pre-money fully diluted shares. Because those shares usually include a new option pool, and sometimes converting SAFEs or notes, the effective pre-money for existing holders is often lower than the headline.
Definition: Pre-money valuation is the value assigned to a company's existing fully diluted equity before new investment, used to calculate the price per share for the round; post-money valuation equals pre-money valuation plus the new money raised.
Two term sheets can show the same number and leave founders with very different stakes.
How to calculate share price from a pre-money valuation
Carta's guide to pre-money and post-money valuations gives the core formula: price per share equals the pre-money valuation divided by the pre-money fully diluted shares. From there, three steps give you every investor's position:
- Price per share = pre-money valuation / pre-money fully diluted shares.
- New shares issued = investment / price per share.
- Ownership = new shares / (pre-money shares + new shares), which equals investment / post-money valuation.
Illustrative worked example: a company has 8,000,000 fully diluted shares and agrees to a $12M pre-money valuation on a $3M round. Price per share is $12M / 8,000,000, or $1.50. The investors receive $3M / $1.50, or 2,000,000 new shares, and own 2,000,000 / 10,000,000, or 20 percent. Post-money is $15M and the founders keep 80 percent.
Now add a common term sheet condition: a new option pool is counted in the pre-money shares. The company creates 1,000,000 new pool shares (about 8.9 percent of the post-closing total), so the price per share falls to $12M / 9,000,000, or about $1.33, and the investors get 2,250,000 shares for the same $3M.
They still own 20 percent of 11,250,000 shares. The founders fall to about 71.1 percent, and the effective pre-money for their 8,000,000 shares is about $10.7M, not $12M. In this structure, founders bear the pool's dilution; the investors do not.
Same $12M on the term sheet. About $1.3M less for the people who built the company.
Why pre-money valuation is the number that gets negotiated
Founders often talk pre-money because it sounds like a verdict on the business. Investors tend to accept the framing because the pre-money, the round size, and the option pool together fix their ownership, and they can adjust any of the three.
Wall Street Prep's formulas make the relationship explicit: post-money equals the investment divided by the ownership it buys, and pre-money is that post-money figure minus the investment. An investor who wants 20 percent for $3M is in effect asking for a $12M pre-money. An investor who says "$15M pre" on a $5M round is asking for 25 percent.
The option pool shuffle
Cooley GO's guidance on negotiating the option pool describes the standard mechanic: investors ask that the full post-closing pool be treated as part of the pre-closing capitalization when calculating price per share, so the pool dilutes only existing holders, not the new shares. The size of that pool can change founder ownership as much as the valuation does.
"A higher pre-money is a better deal"
It sounds obvious. A bigger number means a higher price per share and less dilution, and it's the number founders get to tell their team.
But.
Cooley's example is worth keeping in mind. On a simplified $1M raise, a $15M pre-money with a 20 percent post-closing pool leaves the common stock at 67.05 percent post-money. A $12M pre-money with a 15 percent pool leaves the common stock at 70.28 percent. In that example, the lower headline valuation leaves founders with more of the company. We've written more on whether valuations matter from the investor's chair.
Investors use the pool for a legitimate reason: a company needs equity to hire, and a pool created after the round dilutes the new investors too. In our view, the sensible way to size it is a hiring plan; Cooley recommends an option budget covering the hires needed over the next 12 to 18 months. A 20 percent pool asked of a two-person company with three planned hires looks more like a valuation negotiation than headcount planning. The founder-side guide to option pool strategy gives the same advice from the other chair.
How SAFEs and notes change the effective pre-money valuation
The second adjustment is convertible securities. When SAFEs or convertible notes convert in the priced round, someone absorbs the new shares, and there is no single market rule for who. Cooley GO's article on calculating share price with outstanding notes or SAFEs sets out three methods, using an $8M pre-money, a $2M Series A, 1,000,000 founder shares, and $1M of notes converting at a 30 percent discount:
| Method | Series A price | Founders own | Who absorbs conversion |
|---|---|---|---|
| Pre-money method | $8.00 | 70.0% | Founders and new investors |
| Percentage-ownership method | about $6.57 | 65.7% | Founders only (Series A fixed at 20%) |
| Dollars-invested method | about $7.57 | 68.8% | Mostly founders, less than above |
The percentage-ownership method is generally the most investor-friendly, because conversion shares effectively sit inside the pre-money. Cooley stresses that each side may think it has a deal until this is spelled out, so it is usually worth settling in the term sheet.
A company that raised $1.5M on post-money SAFEs with $10M caps has already promised 15 percent of itself (before the priced round's new pool, which also dilutes those SAFEs under YC's form). The pre-money vs. post-money SAFE guide covers the SAFE side, and the cap table investor guide shows how to build the full pro forma.
Our suggestion: ask for a pro forma cap table showing pre-money shares (including pool and conversions), new shares, and post-money ownership for every holder. If a founder can't produce one, the quoted "pre-money" may be closer to a marketing number.
Pre-money valuation benchmarks in 2026
The Q2 2026 PitchBook-NVCA Venture Monitor says valuations have pushed past their 2021 highs at every series, and that the median pre-money valuation more than doubled relative to 2021 at pre-seed, seed, and Series D+. Carta's Q1 2026 State of Private Markets report says Series B and Series C primary pre-money valuations rose 17.2 percent and 12.5 percent since Q1 2025, and puts the median Series A valuation for a non-AI startup at $55M against about $300M for an AI foundational model company.
Carta's July 2026 fundraising benchmarks, covering rounds raised in the prior six months, show a median seed round of $4.1M at a $24.3M valuation and a median Series A of $14.4M at an $80M valuation. That page does not say whether those valuations are pre-money or post-money, and the difference is not trivial. Read as post-money, $24.3M implies roughly $20.2M pre-money; read as pre-money, it implies roughly $28.4M post-money.
Confirm the basis of any benchmark before you hold it up against a term sheet. Sector, growth rate, geography, and competing term sheets all move the number.
How investors often set a pre-money valuation
- Start from ownership, not price. Many investors decide the ownership the fund model needs, then back into the pre-money from the round size. Carta's July 2026 benchmarks put median seed dilution at about 18 percent for the whole round.
- Sanity-check against exit math. If a plausible exit is $300M and later rounds will each dilute the company further, what entry price still returns a meaningful multiple? The venture capital method valuation guide formalizes this.
- Benchmark against comparable rounds. Carta and PitchBook publish stage medians regularly; check whether each figure is pre-money or post-money.
- Adjust for the pool and conversions. Compute the effective pre-money after both.
- Write the term sheet in shares and percentages, not just dollars.
Where new investors learn to price a round
We think of a pre-money valuation as an argument, and many people get good at it by making it in front of people who do it weekly. 1752vc's Emerging Angels program is an 8-week live program for accredited investors new to angel investing, giving them a seat at the table in a working fund's investment process: live diligence calls, deal reviews, monthly Investment Circles, and a private community. Founders comparing offers can start with the founder-side term sheet guide.
The bottom line
The pre-money is a starting point, not the answer. Compute the effective number after the pool and the conversions, then compare offers on ownership.
The valuation is what gets quoted.
The share count is what gets signed.
Key takeaways
- Pre-money valuation is the company's value before new capital; price per share equals pre-money valuation divided by pre-money fully diluted shares.
- A new option pool counted in the pre-money shares lowers the price per share and dilutes only existing holders, so the effective pre-money falls.
- Who absorbs converting SAFEs and notes is negotiated; Cooley GO describes three methods with materially different founder outcomes.
- PitchBook-NVCA's Q2 2026 Monitor says median pre-money valuations more than doubled versus 2021 at pre-seed, seed, and Series D+.
- Carta's July 2026 benchmarks show a $24.3M median seed valuation without stating pre or post, so it is worth confirming the basis.
- Many investors back into pre-money from a target ownership percentage and exit math, rather than from the founder's headline number.
Frequently asked questions
Pre-money valuation is the value of a startup immediately before a financing round, not counting the new money. It sets the price per share investors pay, calculated as pre-money valuation divided by pre-money fully diluted shares, and together with the round size it determines what percentage of the company the new investors receive.
If you know the post-money valuation, subtract the round size. If you know the investment and the ownership it buys, divide the investment by the ownership percentage to get post-money, then subtract the investment. For example, $3M for 20 percent implies a $15M post-money and a $12M pre-money valuation.
Pre-money valuation is the company's value before the new capital goes in; post-money valuation is pre-money plus the new capital, so the gap is exactly the round size. Price per share is calculated from the pre-money valuation and share count, while each new investor's ownership equals the investment divided by the post-money valuation.
Usually yes. Many standard term sheets count the full post-closing option pool in the pre-money fully diluted shares, which lowers the price per share and dilutes founders and earlier investors rather than the new investors. Cooley GO suggests sizing the pool to a 12 to 18 month hiring plan instead of accepting a default percentage.
Not necessarily. A higher pre-money paired with a larger option pool can leave founders with less of the company. In Cooley GO's example, a $15M pre-money with a 20 percent pool leaves common stock at 67.05 percent, while a $12M pre-money with a 15 percent pool leaves it at 70.28 percent. Comparing offers on fully diluted ownership, not headline price, is usually more telling.
