About these calculators

Online businesses live or die on unit economics: what a customer costs to acquire, what they are worth over their lifetime, how quickly they leave and how fast recurring revenue grows. These calculators cover CAC and payback, LTV:CAC, churn and revenue retention, MRR and ARR, the Rule of 40, ROAS and e-commerce profit.

Each page explains the benchmark ranges investors commonly use, and where those benchmarks mislead.
