Lifetime Value (LTV)
Lifetime Value represents the total net revenue or gross profit a company expects to earn from a customer over the entire duration of the relationship, and when compared against Customer Acquisition Cost in the LTV:CAC ratio, it is the cornerstone unit economics test for Indian consumer internet and fintech businesses.
A business can spend money to acquire a customer today and earn revenue from that customer over months or years into the future. LTV attempts to estimate the present value of that future revenue or profit stream, enabling a comparison against what was spent to win the customer in the first place. Without LTV, CAC is a cost figure with no benchmark; together they define whether a growth-stage business is creating or destroying economic value as it scales.
LTV can be defined in several ways. Gross profit LTV uses the cumulative gross profit expected from a customer over the lifetime, which is more conservative and preferred by sophisticated investors because it excludes the customer's direct cost of service. Revenue LTV simply sums expected revenues and is less rigorous. The discounted LTV applies a present value discount to future cash flows to reflect the time value of money and the uncertainty that the customer relationship will actually last as long as projected.
The inputs to LTV are average revenue per period (often monthly), gross margin on that revenue, and expected customer lifetime (derived from the inverse of churn rate — a customer who churns at 2 per cent per month has an implied average lifetime of 50 months). Each of these inputs carries significant uncertainty, and small changes in assumed churn or margin can move LTV substantially, which is why LTV estimates for early-stage companies should be treated with appropriate scepticism.
In India's lending sector, LTV has a specific application in credit risk — it refers to the loan-to-value ratio on secured loans — so context matters when the term appears in financial documents. In the consumer internet and fintech context, LTV always refers to customer lifetime value.
Policybazaar parent PB Fintech cited improving LTV:CAC ratios as evidence of platform maturation in its post-IPO investor communications. The company argued that customers who purchased their first policy through the platform had high probability of renewing on the platform and purchasing additional product categories, lifting LTV beyond the first transaction. This cross-sell and retention argument is central to how high-CAC businesses justify their acquisition spending, and it should be stress-tested by examining actual cohort renewal rates rather than accepting management projections at face value.
