Lifetime Value (LTV)

What a customer is really worth

Lifetime Value (LTV or CLV) estimates the total profit a business will earn from a single customer across the whole time they stay, not just from one purchase. For a recurring business, a streaming app, a SaaS tool, a D2C brand, that means stacking up every repeat order or subscription payment, minus the cost of serving the customer, over their expected lifespan.

A simple version: average revenue per customer per period, times gross margin, times the average number of periods they stay before churning.

LTV and CAC: the golden ratio

LTV is meaningless on its own; it lives in relation to Customer Acquisition Cost (CAC), what the company spent to win that customer through marketing and discounts. The LTV/CAC ratio is the single most-watched number in startup economics. A healthy benchmark is roughly 3:1, the customer generates three times what it cost to acquire them. Below 1:1, the company loses money on every customer it adds, a fatal flaw that growth only worsens.

Why it dominated India's startup story

During India's funding boom, many consumer-internet and D2C startups grew revenue fast by spending heavily on discounts and ads, inflating CAC while LTV stayed weak. When funding tightened, investors stopped rewarding growth-at-any-cost and started demanding a sound LTV/CAC ratio and a clear path to profitability. Several heavily-funded companies that had ignored this discovered their unit economics never worked.

For anyone evaluating a consumer or subscription business, listed quick-commerce, food delivery, fintech or SaaS, LTV is essential. It separates businesses that are genuinely building loyal, profitable customer bases from those merely renting growth through cash burn. A rising LTV alongside a falling CAC is the clearest sign a consumer business is maturing into something durable.
