Cap Table vs Pro Forma Cap Table: Key Differences Explained
A cap table (capitalization table) shows current ownership — who owns what percentage of the company right now. A pro forma cap table models future ownership after a proposed financing event — showing post-money ownership including new investors, option pool changes, and converted instruments. The cap table is history; the pro forma is planning.
What is Cap Table?
A capitalization table — cap table — is a spreadsheet or document listing every equity holder in a company: founders, employees with vested stock, investors with preferred shares, SAFE holders, and warrant holders. It shows: the number of shares each party holds, the type of security (common, preferred Series A, SAFE), the ownership percentage on a fully diluted basis, and the price paid per share. Cap tables are legal and financial documents — they're central to due diligence in every financing round and acquisition. Modern startups use software like Carta or Pulley to manage their cap tables. A clean, accurate cap table is one of the most important things founders can maintain — a messy one can delay or kill fundraising.
What is Pro Forma Cap Table?
A pro forma cap table models the expected ownership structure after a proposed transaction — typically a new financing round. It shows what the cap table will look like after: the new investors buy in, the option pool is expanded, existing SAFEs/notes convert, and any secondary transactions settle. Pro forma means 'as a matter of form' — it's a forward-looking calculation. When a VC offers a term sheet, they provide a pro forma cap table showing post-close ownership for all parties. Founders should build their own pro forma models to understand the dilution impact of different deal terms before signing. Pro forma cap tables are the tool for negotiating and understanding the real economics of a financing.
Key Differences
| Feature | Cap Table | Pro Forma Cap Table |
|---|---|---|
| Time orientation | Current — today's ownership | Future — post-transaction ownership |
| Purpose | Legal record of ownership | Planning and negotiation tool |
| New investors | Not yet included | Included at proposed terms |
| Convertible instruments | Shown as unconverted | Modeled as converted |
| Option pool | Current authorized pool | Includes proposed expansion |
| Who creates it | Carta, Pulley, or lawyer | Founders or investors modeling a deal |
When Founders Choose Cap Table
- →Due diligence for a new financing round
- →Employee equity grant decisions
- →Calculating dilution from past events
- →Legal reference for any shareholder matter
When Founders Choose Pro Forma Cap Table
- →Evaluating a term sheet from an investor
- →Planning future fundraising rounds
- →Modeling the impact of different SAFE cap amounts
- →Explaining founder ownership post-financing to co-founders
Example Scenario
A startup's current cap table: Founder 1 owns 42%, Founder 2 owns 38%, Angel pool owns 10% (via SAFE), and Option Pool is 10%. A VC proposes investing $4M at a $16M pre-money with a 15% post-money option pool. The pro forma cap table models: the SAFE converts at the pre-money, the option pool expands to 15%, and the VC receives 20% post-money. Founder 1 and 2 go from 80% combined to about 50% combined. Without building the pro forma, founders can't visualize this dilution and can't negotiate intelligently.
Common Mistakes
- 1Not updating your cap table after every equity grant or financing — outdated cap tables cause legal problems
- 2Building pro formas without including SAFE/note conversion — this understates dilution significantly
- 3Forgetting to model option pool expansion as pre-money dilution, not post-money
- 4Using non-fully-diluted share counts in your cap table math
Which Matters More for Early-Stage Startups?
Both are essential. Your cap table is the legal foundation — keep it current and accurate. Your pro forma is the strategic planning tool — build it before every investor conversation. The biggest mistake founders make is not understanding their cap table well enough to know how a proposed term sheet actually affects them.
