Why Use These Calculators?
Angel investing involves complex financial calculations that can significantly impact your returns. These free tools help you make informed decisions by modeling ownership, dilution, and exit scenarios before you commit capital.
Understanding Ownership & Dilution
When you invest in a startup, your ownership percentage decreases over time as the company raises more funding. A typical seed investor might see 40-60% dilution before exit. Our calculators help you model these scenarios so you know what to expect.
SAFE Notes Made Simple
SAFEs (Simple Agreement for Future Equity) are the most common investment instrument for early-stage startups. Understanding how your SAFE converts at a priced round is crucial for knowing what ownership you'll actually receive.
Comparing Opportunities
Not all deals are created equal. Our comparison tool helps you evaluate multiple opportunities side by side, considering factors like valuation, stage, and expected dilution to help you allocate your angel portfolio wisely.
