Unit economics examines the revenue and costs associated with a single customer or unit of product, revealing whether a business model is fundamentally sustainable.
Unit economics analyses the direct revenues and costs attributable to acquiring and serving one customer or delivering one unit of product. It separates these from overhead costs to reveal the underlying profitability of the core business activity.
How much does it cost to get a customer, and how much do they spend over their relationship with the business? If it costs ₹1,000 to acquire a customer who eventually pays ₹500, that is not sustainable. Unit economics shows whether the basic business model works.
A SaaS business charges ₹10,000 per month per customer. Average customer stays for twenty months, generating ₹2,00,000 lifetime revenue. Acquiring each customer costs ₹40,000 in sales and marketing. LTV:CAC is 5:1.
Customer acquisition cost: ₹40,000. Average order value: ₹15,000. Average orders per customer per year: 8. Average customer lifetime: 2 years. Lifetime value: ₹15,000 × 8 × 2 = ₹2,40,000. LTV:CAC = 6:1.
High growth can mask poor unit economics. A business acquiring customers at a loss, betting on future profitability, may grow rapidly but collapse when growth slows or funding dries up.
Understanding unit economics is essential before scaling. Improving acquisition efficiency, increasing customer lifetime value, and reducing churn all improve unit economics. Each has different investment requirements and timelines.
