Post-Money Valuation
Post-money valuation is the agreed company valuation immediately after a financing under the capitalization convention used for that round.
In a simple priced round it is commonly described as pre-money valuation plus new investment. Option-pool changes, convertible instruments, multiple closings, and other capitalization mechanics can change the calculation and ownership result.
Post-money valuation provides financing and ownership context. It is not cash available to operate, accounting equity, or an objective measure of the company’s intrinsic worth.
Connect valuation, new capital, and ownership context
The simple relationship is useful only after the financing convention and capitalization basis are stated.
- 01Pre-money valuation
Agreed value immediately before the financing
- 02New investment
Capital included under the stated round convention
- 03Post-money valuation
Value immediately after that financing convention
- 04Ownership context

What is Post-Money Valuation?
Post-money valuation is the valuation assigned to a company immediately after a financing. In a straightforward priced-equity round, it is often calculated by adding the new investment to the agreed pre-money valuation.
The result helps translate financing terms into ownership context. Dividing a new investor’s investment by the post-money valuation can provide a simplified ownership estimate when the numerator and denominator use compatible definitions. It does not replace a fully diluted cap-table calculation.
SAFEs, convertible notes, option-pool increases, warrants, multiple closings, secondary transactions, and other capitalization terms can change the economics. The financing documents and approved cap table determine the actual ownership effect.
When does the simple formula work?
The relationship works as an orientation for a priced round when pre-money valuation and new investment are defined consistently. It can mislead when the round includes pre-money and post-money instruments, option-pool changes, multiple security classes, or capitalization adjustments outside the simple equation.
Post-money valuation versus cash and accounting equity
Post-money valuation is a financing convention. The company does not receive the full post-money amount as cash; it receives the applicable proceeds. Accounting equity follows the company’s records and accounting framework. Neither number should be substituted for the other.
What should be stated with the number?
Round convention
State whether the valuation is pre-money or post-money and which investment amounts are included.
Capitalization basis
Clarify the fully diluted denominator, option pool, convertibles, warrants, and excluded securities.
Closing and proceeds
Distinguish signed terms, closed investment, fees, secondary sales, and cash actually received by the company.
Why it matters
A small change in the valuation or capitalization basis can materially change dilution. The post-money number is therefore useful only when the investment amount, security terms, option-pool treatment, and denominator are clear.
For operating planning, the separate question is how much new cash reaches the business, when it arrives, and what commitments or milestones that financing is expected to support.
Simplified priced-round relationship
- Agreed pre-money valuation
- New investment included in the convention
- Fully diluted capitalization definition
- Option-pool, SAFE, note, warrant, and closing treatment
Simplified priced-round relationship
Post-money valuation = Pre-money valuation + New investment Approximate new-investor ownership = New investment ÷ Post-money valuation
Illustrative simple priced round
A company agrees an $8 million pre-money valuation and receives $2 million of new investment in a simple priced round. The simplified post-money valuation is $10 million, and the new investment represents approximately 20% of that post-money amount. The actual ownership result can differ if the option pool changes or convertible instruments enter the denominator.
How RunwayCal helps
RunwayCal can place a hypothetical or completed funding event into the appropriate planning context and show how its timing affects the cash path and runway. Hypothetical financing should remain in a Scenario until the event is actually recorded.
RunwayCal is not a valuation engine, cap-table system, securities platform, or legal adviser. Use the executed financing documents and authoritative capitalization records for ownership calculations.
Common mistakes
- 1Treating post-money valuation as the amount of cash the company has.
- 2Using the simplified ownership fraction without defining the fully diluted denominator.
- 3Ignoring option-pool changes, convertibles, warrants, fees, secondary sales, or multiple closings.
- 4Presenting a negotiated financing value as objective intrinsic worth.
- 5Using a planning tool as the authoritative cap table or legal calculation.
