How a pro forma cap table can help you secure your next round

What is a pro forma cap table?

A pro forma capitalization table is a projection of your company’s equity ownership structure after a potential investment, merger, or other financing event. It’s a forward-looking model that shows you and your potential investors what the company’s cap table will look like after the new investment is complete. Think of your current cap table as the official record of who owns what in your company right now. The pro forma cap table, on the other hand, is a scenario.

A pro forma cap table takes your current cap table and adds in the variables of a new funding round, such as a new investment amount and the conversion of previous securities. This allows everyone involved to see the future impact of the deal on every shareholder’s ownership percentage.

Why a pro forma cap table is critical for fundraising

As a founder, a pro forma cap table is one of your most powerful tools during a fundraise. It’s a way to build investor confidence and negotiate from a position of strength. When you present a clean, accurate pro forma to potential investors, you signal that you are a professional and organized early-stage entrepreneur who takes equity management and ownership seriously.

This level of preparation builds immense trust, showing investors you’re ready for their investment and prepared for the process they use to conduct due diligence on high-risk investments.

A pro forma cap table also empowers you by providing a clear picture of equity dilution and its impact on your company’s total outstanding shares and your fully diluted ownership. You can enter negotiations knowing exactly how your ownership stake will change, and with scenario modeling, you can make informed decisions for your company’s future. For example, if you're raising $5 million at a $20 million pre-money valuation, you'll be diluted by 20% ($5 million / $25 million post-money). A pro forma shows this impact across all shareholders instantly.

What are the key components of a pro forma cap table?

To build an accurate pro forma, you need to model several key inputs that typically come from a term sheet, which outlines the basic terms and conditions of an investment, including critical items like liquidation preferences and anti-dilution provisions. Understanding these components is the first step to seeing how a new funding round will reshape your company’s ownership.

Here are the key components you’ll need to model:

• Pre-money valuation: This is the pre-money valuation of your company before a new investment round is added. It’s the starting point for calculating the price per share for the new investors.

• New investment amount: This is the total amount of cash you’re raising in the financing round. This new capital, when added to the pre-money valuation, determines the company’s post-money valuation.

• Convertible instruments: If you’ve raised money on convertible instruments like SAFE agreements or convertible notes, your pro forma must show how they convert into equity. These instruments were designed to become shares during a priced fundraising round and the pro forma does the math based on their specific terms, like valuation caps and discounts.

  • Post-money SAFEs lock in a fixed investor percentage at conversion. Stacking multiple post-money SAFEs at different caps can materially increase dilution at your first priced round. Model each tranche explicitly in your pro forma so there are no surprises.

• New share class: Investors in a priced round typically receive a new class of preferred shares, and you determine the payout structure through waterfall modeling (the order in which proceeds are distributed in an exit). The pro forma will detail this new issuance of stock and show how it fits into the overall capital structure. For exit outcomes, use waterfall modeling to understand payouts by share class and preference terms.

• Employee option pool: As a startup raises capital, investors will often require an increase to the employee stock options pool as part of the financing terms. This practice confirms there’s enough equity set aside to attract and retain future talent and the pro forma calculates the dilutive impact of this increase.

Here’s a quick-reference primer of other relevant metrics and terms:

• Price per share = Pre-money valuation ÷ Pre-money fully diluted shares

• Post-money valuation = Pre-money + new investment

• Post-money ownership: Calculated on a fully diluted basis (including the new option pool and any converting instruments)

• Option pool sizing: Setting a target post-money pool increases the pre-money fully diluted denominator and dilutes existing holders.

Pro forma cap table example: Before and after a Series A

To make the concept more tangible, let’s look at a simple example. A pro forma cap table visually contrasts the company’s ownership structure before and after a new financing round, showing exactly how the ownership percentages shift.

The "Before" column shows a hypothetical simple structure with founders and perhaps some early angel investors or unconverted SAFEs. The "After" column shows the impact of the new investment: the new venture capital investor, the converted SAFEs, and the diluted ownership for the founders and existing shareholders.

How to create a deal-ready pro forma cap table

Building a pro forma cap table can feel overwhelming, especially for the first time. As a founder, you have a choice between the old, risky way of building it in a spreadsheet template and the modern, professional way of using dedicated cap table management software.

The manual way: Building a pro forma cap table in a spreadsheet

For many founders, the first step in financial modeling is opening Excel. It's a common way for companies to track their cap tables, but this manual process for managing pro formas and ownership is filled with potential pitfalls.

A small mistake in a formula can lead to significant miscalculations in ownership, which can damage investor trust and potentially derail a deal. Additional risks include:

• No version control: Multiple versions floating around with different numbers

• No audit trail: Can't track who changed what and when

• No real-time collaboration: Investors and lawyers working off different versions

• Legal liability: Formula errors can lead to misrepresentation claims

An error in calculating ownership under such terms could undermine these critical protections and erode the trust needed to close a deal.

The professional way: Generating a pro forma cap table with Carta

A better approach is to use a platform that serves as a single source of truth for your company’s equity. When your cap table lives on Carta, it becomes the reliable foundation for all your fundraising activities, eliminating the manual errors common in spreadsheets.

Carta’s Deal Pro Forma tool automates the process and pulls data from your live cap table to generate an accurate pro forma model in minutes. Instead of spending hours building and double-checking formulas, you can create a deal-ready pro forma with just a few clicks, giving you and your investors confidence in the numbers.

“Our investor asked if we had an updated cap table to share, and I went to Carta’s dashboard and downloaded it in under one minute. That was amazing.”

How to analyze your pro forma cap table for dilution and ownership

Creating the pro forma cap table is just the first step; using it strategically is what truly matters. The model is your guide to answering the most important question on every founder’s mind: “How much of my company will I own after this round?”

Key negotiation points to model include:

• Pre vs. post-money option pool increases (can save 2-3% dilution)

• SAFE conversion timing and terms

• Board seat thresholds

• Pro-rata rights for existing investors

A pro forma allows you to see the direct impact of dilution on your ownership stake. More advanced tools, like Carta’s Scenario Modeling software, let you compare different term sheets side-by-side. You can adjust variables like the pre-money valuation, investment amount, and the timing of an option pool increase to see how each change affects your ownership in order to reduce the total dilutive impact on your ownership. This turns a complex math problem into a clear, strategic decision, empowering you to negotiate the best possible terms.

Failing to model dilution is a common and costly mistake for early-stage founders, who may not realize how quickly their ownership stake can shrink. After a seed round, the median founding team collectively owns just 56.2% of their company; by Series B, that figure drops to 23%, according to a 2025 report on founder ownership.

As Peter Walker, Head of Insights at Carta, explains: "The reason why sometimes founders find themselves overly diluted when they come to their first couple of priced rounds is often an over-reliance or an over-usage of SAFEs at many different valuation caps and an inability to track that dilution."

This observation about an over-reliance on SAFEs is substantiated by data showing their extended use beyond initial funding stages. Instead of moving directly to a priced Series B, many companies are using unpriced instruments to bridge the gap. This pattern is increasingly common. In the first quarter of 2024, bridge rounds using unpriced instruments reached historically high levels, accounting for 43% of all funding activity for companies that had already raised a Series A. This trend means founders need to be even more vigilant about tracking cumulative dilution across multiple instruments.

Mihir Pershad, CEO of Umami Bioworks, uses scenario modeling to have more productive conversations with his board. “It helps me make the case that we need a certain percentage for our ESOP to hit our objectives. I can show how little or big of a difference that actually makes in a final pro forma. It’s just easier than having speculative conversations.”

From pro forma to closed deal: What comes next

The pro forma cap table is a critical milestone in your fundraising journey, but it’s not the final step. Once you and your investors agree on the terms modeled in the pro forma, the work of closing the round and managing your new capital structure begins.

After you finalize the deal, you'll have new accounting requirements and filings to consider, and one of the first things you’ll need is a new 409A valuation. This independent appraisal of your company’s fair market value (FMV) is required to set the strike price for any new stock options you grant to employees. A financing is a material event that often leads to a higher 409A FMV; you’ll need a new 409A after the round, so it’s important to complete it promptly.

Carta is an end-to-end platform that supports you through the entire fundraising journey, from modeling your pro forma cap table to getting your post-round 409A valuation and beyond.

Frequently asked questions about pro forma cap tables

What is a PF cap table?

PF is a common abbreviation for pro forma. A PF cap table is simply another name for a pro forma cap table, which projects your company's ownership after a financing event.

How do SAFEs and convertible notes affect a pro forma?

A pro forma cap table is where you calculate how these instruments convert into equity. Based on the terms in each agreement, the model determines the number of shares each SAFE or convertible note holder receives in the new funding round.

Is a pro forma cap table legally binding?

No, a pro forma cap table is a projection and is not a legally binding document. The signed financing agreements, such as the stock purchase agreement and amended corporate charter, are what make the deal and the new ownership structure official.

What are common red flags in a pro forma?

Watch out for unexplained ownership gaps, conversion calculations that don't match SAFE terms, missing employee pool increases, or numbers that don't reconcile with your current cap table. Any of these could signal errors that need correction before presenting to investors.
