About The Angel Equity Calculator

The Angel Equity Dilution Calculator is a free, privacy-first financial modeling tool designed specifically for startup founders, early-stage employees, and angel investors. Our goal is to make complex cap table math accessible, transparent, and easy to understand.

Why We Built This Tool

We created the Angel Equity Dilution Calculator to solve a very specific, recurring problem in the startup ecosystem: founders often sign term sheets without fully visualizing how the combination of new investment, convertible notes, SAFEs, and pre-money ESOP (Employee Stock Ownership Plan) expansions will impact their final ownership percentage.

Too often, early-stage founders give away too much of their company simply because they lack the tools to properly model these mechanics. We are here to change that by providing a real-time, visual breakdown of dilution.

Our Core Philosophy: Privacy & Transparency

We believe that your financial data is exactly that—yours. That is why the Angel Equity Calculator is built as a 100% client-side application.

• No Data Harvesting: We do not collect, store, or transmit your cap table data, valuations, or investment amounts to any servers.
• No Sign-ups Required: You don't need to create an account or hand over your email address to use the core features of this tool.
• Instant Results: Because everything runs in your browser, calculations are instantaneous and secure.

Who Is This For?

Whether you are raising a $500k pre-seed round on a SAFE or a $3M priced seed round, understanding your post-money valuation and effective dilution is critical. This tool helps:

• Founders negotiate better terms and protect their voting control.
• Early Employees understand the true value of their equity grants and options.
• Angel Investors quickly model how their capital will convert alongside other instruments.
