Frequently Asked Questions
What is a SAFE and how does it work?
A SAFE (Simple Agreement for Future Equity) is an investment contract that gives investors the right to receive equity in a future priced round. SAFEs convert to equity at a discount or valuation cap, whichever gives the investor a better price. Our SAFE Calculator helps you model different scenarios.
How do I calculate my startup runway?
Runway is calculated by dividing your cash on hand by your monthly burn rate. For example, if you have $500,000 and spend $50,000/month, your runway is 10 months. Our Burn Rate Calculator helps you track spending and project how long your funding will last.
What is the difference between pre-money and post-money valuation?
Pre-money valuation is your company value before receiving new investment. Post-money valuation equals pre-money plus the investment amount. If your pre-money is $4M and you raise $1M, your post-money is $5M, and investors own 20% ($1M/$5M).
How does startup equity dilution work?
Dilution occurs when new shares are issued, reducing existing shareholders percentage ownership. If you own 50% of 1M shares, and 1M new shares are issued, you now own 25% of 2M shares. Our Dilution Calculator models this across multiple funding rounds.
Are these calculators suitable for fundraising?
Yes, our tools are designed to help founders prepare for investor conversations. However, these are estimation tools. For actual fundraising, work with lawyers and financial advisors to ensure proper legal documentation and compliance.
