SaaS Burn Rate & Runway
Calculate runway with dynamic expense growth, funding rounds, and SaaS unit economics (LTV/CAC, ARR, NRR).
Overview
What is a SaaS Burn Rate & Runway?
A Burn Rate & Runway model calculates how long a startup can operate before running out of cash. It factors in monthly expenses, revenue growth, funding rounds, and key SaaS metrics like LTV/CAC ratio, ARR, and net revenue retention to project when additional funding will be needed.
Startup founders monitor burn rate to plan fundraising timelines. VCs use runway analysis to assess portfolio company health. Finance students studying venture capital use it to understand startup economics.
