Pre-Money vs Post-Money Valuation Calculator
Calculate pre-money and post-money valuations, ownership percentages, and dilution for startup funding rounds.
Input your valuation data
Formula
Post-Money Valuation = Pre-Money Valuation + Investment Amount. This represents company value after the investment is added.
Pre-Money Valuation = Post-Money Valuation - Investment Amount. This represents company value before the investment.
Ownership Percentage = (Investment Amount / Post-Money Valuation) × 100. The percentage of the company the investor receives.
Investment Amount = Post-Money Valuation × (Ownership Percentage / 100). The cash invested for the ownership stake.
Pre-money and post-money valuations are fundamental concepts in startup financing. Pre-money is the value before investment, post-money includes the investment. The difference determines ownership percentage and dilution.
Steps
Enter pre-money valuation (company value before investment) or post-money valuation (value after investment).
Enter investment amount or ownership percentage being sold.
Review calculated pre-money, post-money, ownership percentage, and dilution impact.
Assess reasonableness of valuation and ownership terms.

The Definitive Guide to Pre-Money vs Post-Money Valuation: Understanding Startup Funding Valuations
A comprehensive guide to pre-money and post-money valuations in startup funding, including ownership percentages, dilution, and investment term negotiations.
Pre-money valuation is the company's value immediately before receiving new investment, representing the value of existing shares. Post-money valuation is the company's value immediately after receiving investment, equal to pre-money plus the investment amount.
The Core Relationship
The fundamental equation is: Post-Money Valuation = Pre-Money Valuation + Investment Amount. This relationship determines ownership percentage: Ownership % = (Investment / Post-Money) × 100.
Why It Matters
Understanding pre-money vs post-money is critical for:
Founders: Knowing how much ownership they retain after investment
Investors: Understanding the ownership percentage they receive
Negotiations: Structuring investment terms and valuations
Future rounds: Planning for dilution across multiple funding rounds
Calculation and Formulas
Basic Formulas
Post-Money = Pre-Money + Investment
Ownership % = (Investment / Post-Money) × 100
Investment = Post-Money × (Ownership % / 100)
Example Calculation
If a company has a $5M pre-money valuation and receives a $1M investment:
Post-money valuation = $5M + $1M = $6M
Investor ownership = ($1M / $6M) × 100 = 16.67%
Founder ownership = 100% - 16.67% = 83.33%
Ownership Percentage and Dilution
Understanding Dilution
Dilution is the reduction in existing shareholders' ownership percentage when new shares are issued. For founders who owned 100% before investment, dilution equals the investor's ownership percentage.
These ranges vary based on company stage, traction, market size, and negotiation dynamics.
Option Pools
Option pools for employees are often created before investment (pre-money) or after (post-money). Pre-money option pools reduce effective pre-money valuation for founders, while post-money pools don't affect investor ownership percentage.
Valuation Negotiation and Best Practices
Negotiating Pre-Money Valuation
Negotiate based on:
Traction: Revenue, users, growth rate, and key metrics
Market size: Total addressable market (TAM) and growth potential
Team strength: Founder experience and team capabilities
Comparables: Similar companies' valuations and funding rounds
Competitive position: Market position and competitive advantages
Best Practices
Plan for future rounds: Consider total dilution across multiple rounds
Balance valuation and ownership: Higher pre-money means less dilution but may create pressure to grow
Consider option pools: Understand whether pools are pre-money or post-money
Triangulate methods: Use comparable company valuations, DCF, and precedent transactions
Conclusion
Pre-money and post-money valuations are fundamental concepts in startup financing. Pre-money is the value before investment, post-money includes the investment. The relationship determines ownership percentage and dilution. Understanding these concepts is essential for founders and investors to structure fair investment terms and plan for future funding rounds.
FAQs
What is pre-money valuation?
Pre-money valuation is the company's value immediately before receiving new investment. It represents the value of existing shares before the investment is added to the company.
What is post-money valuation?
Post-money valuation is the company's value immediately after receiving new investment. It equals pre-money valuation plus the investment amount: Post-Money = Pre-Money + Investment.
How do I calculate ownership percentage?
Ownership percentage = (Investment Amount / Post-Money Valuation) × 100. Alternatively, if you know pre-money and investment: Ownership % = Investment / (Pre-Money + Investment) × 100.
What is dilution?
Dilution is the reduction in existing shareholders' ownership percentage when new shares are issued. If founders owned 100% before and now own 80%, they experienced 20% dilution.
How does pre-money vs post-money affect ownership?
For the same investment amount, a higher pre-money valuation means investors receive a smaller ownership percentage. Lower pre-money means investors get more ownership for the same investment.
What is a typical ownership percentage for seed rounds?
Seed rounds typically involve 10-25% dilution. Series A often involves 15-30% dilution. The exact percentage depends on company stage, traction, market size, and negotiation dynamics.
How do I negotiate pre-money valuation?
Negotiate based on traction, market size, team strength, competitive position, and comparable company valuations. Higher traction and growth justify higher pre-money valuations. Consider future funding needs to avoid over-dilution.
What about option pools?
Option pools are often created before investment (pre-money) or after (post-money). Pre-money option pools reduce effective pre-money valuation for founders. Post-money pools don't affect investor ownership percentage.
How does this affect future rounds?
Higher pre-money valuations in early rounds can make future fundraising easier but may create pressure to grow into the valuation. Lower pre-money may provide more room for growth but signals lower confidence.
What is the difference between pre-money and post-money for investors?
Investors care about post-money valuation as it determines their ownership percentage. Pre-money is more relevant for founders as it determines how much of the company they retain after the investment.
