Finance term
Post-Money Valuation
Also known as: post-money, post-investment valuation
Definition
Post-money valuation is the company's implied value immediately after a new investment closes — equal to pre-money valuation plus the new investment. It determines the investor's ownership percentage and the per-share price at which the round is priced. The SEC requires post-money valuation disclosure in Regulation CF (crowdfunding) Form C filings. See sec.gov/cfportal.
Detailed explanation
Post-money valuation is the 'after the money is in' company value. It is calculated simply: Post-money = Pre-money + New Investment. While the formula is simple, the post-money figure drives multiple critical deal mechanics.
**Ownership percentage:** Investor ownership = New Investment / Post-money valuation. This is the fundamental dilution calculation. A $2M investment into a company with $10M post-money gives the investor exactly 20%.
**Share price at closing:** In priced rounds (Series A and beyond), post-money valuation divided by fully-diluted shares outstanding (including options, warrants, convertible notes) determines the price per share for the new investment. This price becomes the reference point for anti-dilution adjustments in future rounds.
**SAFE post-money mechanics:** Y Combinator's post-money SAFE (introduced 2018) sets the valuation cap on a post-money basis — meaning the cap represents the company's full post-money value after all SAFEs convert, making dilution calculations more predictable for founders. Pre-money SAFEs (older structure) set caps on a pre-money basis, which creates uncertainty about total dilution as more SAFEs are issued on top. Understanding whether a SAFE is pre- or post-money is critical for founders managing dilution. See sec.gov/smallbusiness/exemptofferings/safe for SEC guidance on SAFEs.
**Follow-on rounds and markups:** When a company raises a subsequent round at a higher post-money valuation, prior investors experience a 'markup' — their ownership percentage dilutes slightly (from new shares issued) but the per-share value increases. VC funds report unrealized portfolio returns based on the latest post-money valuations of their holdings. The Federal Reserve's Survey of Small Business Finances and SBIC programs track equity investment in private companies at sec.gov/divisions/investment/sbcguide.shtml.
◈ Worked example
- Series A arithmetic: Pre-money = $8M. New investment = $2M. Post-money = $10M. Investors own 20%. Founders/employees own 80% (before accounting for option pool). Price per share = $10M / 10M fully-diluted shares = $1.00/share.
- SAFE conversion: A company raised $500K on a post-money SAFE with a $5M valuation cap. At Series A ($8M pre-money, $10M post-money), the SAFE converts at the cap price: $5M / fully-diluted shares at cap. The post-money SAFE structure means the $500K investor knows exactly they own $500K/$5M = 10% before the Series A (ignoring any discount provision).
- Down round calculation: Company last raised at $20M post-money (Series A). New bridge at $12M post-money. Investors with 1x non-participating liquidation preference are protected on downside; founders and common shareholders bear the brunt of dilution in the down round recapitalization.
Common questions
The most-asked questions about Post-Money Valuation — answered straightforwardly.
Does a higher post-money valuation always benefit founders? +
Not necessarily. A very high post-money valuation creates a high bar for the next round — if the company can't grow into the valuation, the next financing may be a down round, which triggers anti-dilution protection for preferred investors and causes significant founder dilution. Founders sometimes benefit from accepting a more moderate valuation that is achievable, preserving clean capital structure for future rounds.
How does post-money valuation affect future dilution planning? +
Post-money valuation determines the share price at the current round. Higher share price = fewer new shares issued per dollar raised = less dilution from future rounds. A company raising subsequent rounds at progressively higher valuations maintains founder ownership better than one raising flat or down rounds, because each new dollar buys fewer shares at higher prices.
