Growth means nothing if each customer costs more than they're worth. Enter your ARPU, margin, churn, and CAC to see your LTV, LTV:CAC ratio, and payback period instantly — then model MRR and unit economics across the year.
MRR, churn, and unit economics — forecast the whole year.
🔒 Secure checkout via Stripe · Excel & Google Sheets · instant delivery.
A common benchmark is 3:1 or higher — you earn at least three times what it costs to acquire a customer, with CAC ideally paid back within about 12 months. The calculator shows both instantly, and the model tracks them over time.
Just your average revenue per customer, gross margin, monthly churn, and customer acquisition cost. The free tool returns your LTV, LTV:CAC, and payback; the paid model forecasts MRR and these metrics across a full year.
A ready-to-use spreadsheet (Excel & Google Sheets): an assumptions tab, a monthly MRR & customer build, unit-economics calculations, and a metrics dashboard — delivered instantly after checkout. AI-assisted, human-built; not financial advice.
