SaaS & Customer Economics
Calculators for customer acquisition, retention, and subscription business economics.
How these calculators help
These calculators connect acquisition spend, customer value, and ratio-based planning. CAC estimates what it costs to win a customer, CLV/LTV estimates the value of a customer relationship, and LTV:CAC compares the two using a basis you choose.
Keep cohorts, time periods, and gross-profit or revenue basis consistent across the tools; mixing definitions can make a ratio look better or worse than the underlying economics justify.
Read the LTV:CAC ratio guide for a worked value-versus-cost comparison.
