fin.saas-rule-of-40 Calculator
Calculates the SaaS Rule of 40 score (ARR growth rate + profit margin) and rates the business against the >40% threshold. Top-quartile SaaS companies consistently score above 40 — elite companies like Veeva and Datadog score above 60.
Inputs
Arr Growth Rate Pct
Annual percentage increase. Enter as a percentage. Compound growth is exponential — small differences in rate become enormous over long periods.
Ebitda Margin Pct
Profit as a percentage of revenue. Margin % is always lower than markup % — a $5 profit on a $15 selling price is 33% margin but 50% markup.
Arr Current M
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Burn Rate M Mo
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
Rule of 40 score
A numerical rating from the scoring model in use.
