About This Template
Model startup ownership and equity dilution across multiple funding rounds with this professional Cap Table & Dilution Calculator Excel template. Perfect for founders, early-stage investors, and finance professionals who need to understand how seed rounds, Series A investments, and option pool expansions affect ownership stakes.
What You Can Calculate
This template computes the complete ownership picture from founding through Series A:
- Founder Combined Ownership — Your final equity stake after all dilution events
- Total Dilution — Cumulative percentage ownership lost from founding to current state
- Pre-Money Valuations — Implied company value before each investment round
- Price Per Share — What each share is worth at Seed and Series A
- Investor Ownership — Final stakes held by Seed and Series A investors
- Option Pool Impact — How the pool shuffle affects all stakeholders
Required Inputs
Enter your founding share allocation, option pool percentage, and funding round details:
- Founder 1 & 2 share counts (typically 4-5 million each)
- Initial option pool percentage (typically 10-15%)
- Seed investment amount and post-money valuation
- Series A investment amount and post-money valuation
- Option pool increase at Series A (the "pool shuffle")
Methodology
The template uses standard venture capital math: Investor Ownership = Investment / Post-Money Valuation. New shares are calculated as Pre-Round Shares / (1 - Ownership%) - Pre-Round Shares. The option pool shuffle formula (New Pool = Pre-A Shares x q / (1-q)) correctly models how VCs require pool expansion before their investment, diluting existing shareholders.
Assumptions & Limitations
- Single share class (common stock mechanics)
- No anti-dilution provisions or liquidation preferences
- Pool increase is incremental, not a target percentage
- Up to 2 founders and 2 funding rounds modeled
Frequently Asked Questions
The Pool Increase % is an incremental addition to the option pool, created pre-money before Series A. This dilutes all existing shareholders (founders and seed investors) before the Series A investors ownership is calculated. The formula is: New Pool Shares = Pre-A Shares * q / (1-q), where q is the pool increase percentage.
Due to Excel rounding for display purposes, percentages may show slight variations. The underlying calculations maintain full precision. The actual shares always add up correctly - check the share count columns for exact figures.
This template models up to 2 founders and 2 funding rounds (Seed + Series A). For more complex scenarios with multiple founders, SAFEs, convertible notes, or later rounds, you can extend the formulas or use a dedicated cap table management tool.
