SaaS Business Metrics Calculator

Check if your SaaS can scale profitably with CAC, LTV, payback, and Rule of 40 analysis.

What it is

A framework to evaluate whether your SaaS business model is financially healthy and ready to scale. Calculate customer lifetime value, acquisition costs, cash runway, and growth efficiency. Built for founders and PMs who need to make smart decisions about when to invest in growth vs. when to optimize for profitability.

What it does

  • Calculates customer lifetime value (LTV) and acquisition cost (CAC) to see if your model is sustainable
  • Measures cash runway and burn rate so you know how long you can operate before needing more funding
  • Computes Rule of 40 and other efficiency ratios to balance growth against profitability
  • Analyzes payback periods and gross margins to determine if you're ready to scale marketing spend
  • Compares acquisition channels to find which ones recover costs fastest

Use it when

  • You're preparing a board deck and need to show your unit economics are sound
  • You're deciding whether to scale paid acquisition or optimize conversion first
  • You need to justify marketing spend or prove your business model can support growth
  • You're planning fundraising and want to show healthy SaaS metrics to investors
