Raising capital is one of the most important milestones for any startup. Whether you’re a founder preparing for your first funding round or an investor evaluating an opportunity, understanding post-money valuation is essential. It determines how much your company is worth after receiving investment and how ownership is divided between founders and investors.

What Is a Post Money Valuation?
A post-money valuation is the value of a company after it receives an investment. It represents the combined value of the company's existing valuation and the new capital invested.
For example, if a startup is valued at $4 million before investment and receives $1 million in funding, the post-money valuation becomes $5 million.
Understanding post-money valuation helps everyone involved clearly determine ownership percentages after an investment round.

2. Investment Amount
Shows the total capital invested.

Post Money Valuation Formula
The calculator uses a straightforward financial formula.
Formula for Post-Money Valuation
Post-Money Valuation = Pre-Money Valuation + Investment Amount
Formula for Investor Ownership
Investor Ownership (%) = (Investment Amount ÷ Post-Money Valuation) × 100
Formula for Founder Ownership
Founder Ownership (%) = 100 − Investor Ownership (%)
These formulas are widely used in startup finance and venture capital transactions.
Example Calculation
Let's assume the following values:
Pre-Money Valuation: $2,500,000
Investment Amount: $500,000
Step 1
Post-Money Valuation
= $2,500,000 + $500,000
= $3,000,000
Step 2
Investor Ownership
= ($500,000 ÷ $3,000,000) × 100
= 16.67%
Step 3
Founder Ownership
= 100 − 16.67
= 83.33%
Final Results
- Pre-Money Valuation: $2,500,000
- Investment Amount: $500,000
- Post-Money Valuation: $3,000,000
- Investor Ownership: 16.67%
- Founder Ownership: 83.33%
Another Example
Suppose a startup has:
- Pre-Money Valuation: $8,000,000
- Investment Amount: $2,000,000
Calculation
Post-Money Valuation
= $8,000,000 + $2,000,000
= $10,000,000
Investor Ownership
= ($2,000,000 ÷ $10,000,000) × 100
= 20%
Founder Ownership
= 80%
This means investors own one-fifth of the company after the investment round.
