Dilution for SaaS Founders
What is Dilution?
Dilution is the reduction in your ownership percentage when new shares are issued, such as in a funding round. It shows how much of the company you give up for capital.
Why Dilution matters for SaaS founders
Understanding dilution helps you negotiate fair terms and plan your cap table. Founders should know how much they are giving up and what they get in return.
How to calculate Dilution
Your dilution from a round is roughly: your current equity percentage × (investment / post-money valuation). This estimates how much of your stake is diluted.
Dilution = Founder Equity × (Investment / Post-Money Valuation)

Example calculation
- 100% × ($500,000 / $2,000,000)
- 100% × 0.25
- 25% dilution
Result: 25%
You give up 25% of the company. Your ownership drops from 100% to 75%. You now own 75% of a $2M company.
Benchmarks & best practices
- Early-stage: Seed rounds often dilute founders 15-25%. Series A may add another 20-25%.
- Healthy range: Dilution is a trade-off. More capital can mean faster growth and a larger outcome. Focus on ownership value, not just percentage.
- Warning range: Excessive dilution early can leave little for later rounds and team. Model your cap table before signing.
Frequently Asked Questions
- How much dilution is normal in a seed round?
- Seed rounds typically dilute founders by 15-25% for $500k-$2M. The exact amount depends on valuation, round size, and negotiation. Understand the trade-off before committing.
- What is post-money valuation?
- Post-money valuation is the company value after the investment. It equals pre-money valuation plus the investment. For example, $1.5M pre + $500k investment = $2M post-money.
- How do I minimize dilution?
- Raise at higher valuations, raise less capital, or use alternatives like revenue-based financing. Strong traction and multiple term sheets improve your position.
