Understanding Startup Runway

What is Runway?

Runway is the number of months your startup can operate before running out of cash, assuming no additional funding. It's calculated by dividing your current cash by your monthly burn rate (expenses minus revenue).

Why Simple Runway Isn't Enough

Basic runway calculations assume static burn rates. In reality, your expenses grow as you hire, and (hopefully) your revenue grows too. This calculator models those dynamics so you can make better decisions about hiring pace and fundraising timing.

Stage-Appropriate Benchmarks

We automatically detect your stage based on revenue and provide relevant benchmarks:

  • Pre-Seed: 18+ months ideal, 12+ minimum
  • Seed: 18+ months ideal, 12+ minimum
  • Series A: 24+ months ideal, 15+ minimum
  • Series B: 24+ months ideal, 18+ minimum

When to Start Fundraising

Rule of thumb: start fundraising when you have 9-12 months of runway remaining. A typical raise takes 3-6 months, and you want buffer for negotiations and unexpected delays.
