What is Customer Profitability Analysis?
Customer profitability analysis measures the actual profit a company earns from each customer or customer segment, after accounting for the true cost of serving them — not just the revenue they generate.
Customer profitability = Revenue from a customer − Cost to serve that customer, revealing which customers actually create value versus which ones destroy it.

Step-by-step worked examples
Customer A generates $120,000 in revenue but requires $95,000 in service costs (support, discounts, delivery). Find customer profit.
Customer Profit = Revenue − Cost to Serve = 120,000 − 95,000 = $25,000 profit
Customer B generates $80,000 in revenue but demands rush shipping and heavy support, costing $88,000 to serve. Find customer profit.
Customer Profit = Revenue − Cost to Serve = 80,000 − 88,000 = −$8,000 (unprofitable customer)
A company has 3 customers with profits of $25,000, −$8,000 and $12,000. Find total customer profit and identify the least profitable.
Total = 25,000 + (−8,000) + 12,000 = $29,000 Least profitable = Customer B (−$8,000), a candidate for repricing or dropping

Common mistakes
Judging customer value by revenue alone. — Correct: A big-revenue customer can still be unprofitable if their service costs are high enough — always subtract cost to serve.

Treating all customers as equally important to keep. — Correct: Use the analysis to reprice, renegotiate terms with, or even drop chronically unprofitable customers.
Assuming unprofitable customers are rare exceptions. — Correct: In many businesses the 'whale curve' shows a large share of customers are actually unprofitable, offset by top performers.
