Mastering SaaS Unit Economics

Unit economics determine whether a SaaS company can scale profitably. If acquiring a customer costs more than the cumulative net margin they generate over their lifespan, increased sales volume only accelerates cash burn.

Our Unit Economics calculators reveal the true return on acquisition spend. Measure average customer acquisition cost with the CAC Calculator, project multi-year revenue with the LTV Calculator, benchmark health against venture standards (3:1+ LTV:CAC) with the LTV:CAC Ratio Calculator, measure sales efficiency with the Magic Number Calculator, or verify growth vs profitability health using the Rule of 40 Calculator.
