Detailed Overview
Customer Lifetime Value and CAC Ratio Calculator works out the economics of a subscription business: what it costs to win a customer (CAC), how much that customer is worth over their lifetime (LTV), the LTV to CAC ratio, and how many months it takes to earn back the acquisition cost. These figures show whether growth is sustainable or whether each new customer quietly loses money.
To use it, enter your acquisition spending, the number of new customers it won, your average revenue per customer and your churn or retention figures. Read the ratio first: a ratio well above one means customers repay their cost several times over, while a ratio near or below one means the business model needs attention before it scales.
Check your churn and lifetime assumptions, because they drive the whole result. A small change in monthly churn can move lifetime value dramatically, and averages can hide the difference between loyal customers and ones who leave after a month. Re-run the calculation with your best and worst churn figures to see the range, not just a single number.
One honest limitation: the result is an estimate built on averages, not a prediction for any individual customer. It cannot account for price changes, new competitors or shifts in customer behaviour, so use it to guide pricing and spending decisions, not as a guarantee of future revenue.
