Every what-if breaks another formula
An investor asks what happens if the round is $750,000 instead of $1,000,000. You copy the spreadsheet, change a few cells and break a formula. After several rounds the file is a mish-mash of versions, and nobody knows which one is current.
Four steps to the cap table after the round
- Add your stakeholders and their shares.
- Add the round: the investment and the pre-money valuation.
- Read the cap table after the round, holder by holder.
- Change a number and read it again.
Price per share = pre-money valuation ÷ shares outstanding before the round. Shares issued = investment ÷ price per share. Each holder's percentage = their shares ÷ total shares after the round.
Worked example: a $1,000,000 round against $750,000
Assumptions: two founders, one class of shares, no option pool, no SAFEs, one investor. Founder A holds 6,000,000 shares and Founder B holds 4,000,000, so 10,000,000 in total. The pre-money valuation is $4,000,000.
A $1,000,000 round
Price per share:
$4,000,000 ÷ 10,000,000 = $0.40
Shares issued to the investor:
$1,000,000 ÷ $0.40 = 2,500,000
Total after the round:
10,000,000 + 2,500,000 = 12,500,000
Check:
12,500,000 × $0.40 = $5,000,000, which is pre-money plus investment.
The same round at $750,000
Shares issued:
$750,000 ÷ $0.40 = 1,875,000
Total after the round:
10,000,000 + 1,875,000 = 11,875,000
Check:
11,875,000 × $0.40 = $4,750,000.
| Holder | Shares before | After $1,000,000 | After $750,000 |
|---|---|---|---|
| Founder A | 6,000,000 | 6,000,000 ÷ 12,500,000 = 48.0% | 6,000,000 ÷ 11,875,000 = 50.5% |
| Founder B | 4,000,000 | 4,000,000 ÷ 12,500,000 = 32.0% | 4,000,000 ÷ 11,875,000 = 33.7% |
| Investor | 0 | 2,500,000 ÷ 12,500,000 = 20.0% | 1,875,000 ÷ 11,875,000 = 15.8% |
| Total | 10,000,000 | 100.0% | 100.0% |
In the $1,000,000 round every existing holder keeps 0.80 of their stake: A goes from 60% to 48%, B from 40% to 32%. At $750,000 they keep 0.84.

Where the Cap Table Simulator stops
- It does not touch your real cap table. It is scratch paper.
- It prices the round off shares outstanding. An option pool added before the round changes the price per share. Size the pool with the ESOP Calculator.
- It does not convert SAFEs. Use the SAFE Calculator.
Scratch paper is fine until the round is real
On BildrX the same model runs on your real holders, in Cap Table. SAFEs and notes convert inside it, the exit waterfall sits beside it, and it stays read-only until you commit. When the round closes, the new shares post to an append-only ledger, and every number traces to the entry behind it.
What's free, what's Pro
Free records what you have already issued. Pro runs the model on your real holders with unlimited scenarios, and converts SAFEs and notes inside it. Compare the plans on pricing.
