1. Existing holders

One per line: name, shares, type. Type is common, preferred or pool. For example Founder A, 4000000, common.

2. SAFEs and convertible notes (optional)

One per line: name, amount, valuation cap, discount %, type. Type is safe or note. For example Angel, 250000, 5000000, 20, safe. Leave the cap or discount as 0 if there is none.

3. The new priced round

The post-round cap table appears here.

4. Exit waterfall

Model a round first, then the waterfall shows what each holder is paid.

What this is, and what it is not

It does the standard arithmetic in the open. SAFEs and notes convert on the post-money cap method, taking the better of the valuation cap or the discount; the option pool is topped up pre-money so it dilutes the existing holders, not the new investor; and the exit waterfall pays liquidation preferences first, then splits the rest, with non-participating preferred converting to common when that pays more.

It is a model, not the deal. Real term sheets carry seniority stacks, pro-rata rights, anti-dilution, multiple SAFE methods and edge cases this does not capture. Treat the numbers as a clear first look to negotiate from, and have your lawyer and the actual documents confirm anything you rely on.

It is not investment or legal advice. Modelling a dilution is not a recommendation to take or refuse a deal.

Nothing leaves this tab. The numbers you type stay in browser memory and are never sent anywhere.
