About this calculator

This calculator estimates Customer Lifetime Value using CLV = ARPU × gross margin × average customer lifespan — the total profit a business can expect from a typical customer over the entire relationship, not just from a single purchase.

Startups and subscription businesses use it to check that their customer acquisition cost (CAC) leaves enough room for profit — a common rule of thumb targets an LTV:CAC ratio of at least 3:1 — while marketing teams use it to decide how much they can afford to spend acquiring a new customer in a given channel.
