About the Fundraising Dilution Simulator
Model a Seed, Series A, and Series B in sequence. Returns post-money, new-investor ownership, and exactly what founders retain after each round — so you can see the full dilution path from day one.
It's built for directional planning: change any assumption and watch the whole projection move, the way a seasoned operator pressure-tests a plan before committing capital. Everything is computed live in your browser — nothing is sent anywhere.
How the Fundraising Dilution Simulator Works
The model takes 6 assumptions and returns 3 headline metrics plus a full breakdown. Here is exactly what goes in and what comes out — no black box.
The Inputs
| Assumption | Example value |

| Seed raise | $1,500,000 |
| Seed pre-money | $6,000,000 |
| Series A raise | $8,000,000 |
| Series A pre-money | $24,000,000 |
| Series B raise | $20,000,000 |
| Series B pre-money | $80,000,000 |

The Operator's Read
Founders keep 48% through Series B. Healthy. Each point of pre-money you negotiate now compounds across every future round.
Assumptions & Limitations
- •The model is deterministic: it projects your inputs forward with clear arithmetic, not a Monte-Carlo or probabilistic forecast. It shows one scenario at a time — run several to bracket a range.
- •Defaults are illustrative benchmarks, not your business. Replace every field with your real numbers before drawing conclusions.
- •It abstracts away taxes, financing, seasonality, and one-off events unless a field explicitly captures them. Treat the output as a directional estimate.
- •This is an educational tool, not financial, investment, tax, or legal advice. Validate real decisions with a qualified professional.
