customer lifetime value
Customer lifetime value is the total profit a business expects to earn from a customer over the entire duration of the relationship.
Customer lifetime value measures how much total profit you can expect from a single customer throughout their relationship with your business. It’s not just a finance metric. It’s a strategic lens. When you know how much each customer is worth over time, you know how much you can spend to acquire and keep them—without burning margin or scaling chaos.
This value depends on average revenue per customer, retention rate, and gross margin. High LTV means strong retention, efficient delivery, and pricing that works. Low LTV? It means short relationships or weak economics—and it’s a warning.
How teams use customer lifetime value
A B2B startup calculates that its average customer pays $12K per year and stays for three years, with a 70% gross margin. That puts LTV at $25,200. With a CAC of $6,000, the business is in good shape. They use this number to set budget, model growth, and defend valuation.
In another case, a subscription brand sees great acquisition but low retention. LTV lands below CAC. The team invests in onboarding, usage tracking, and personalized engagement. Over six months, churn drops and lifetime value doubles—making paid acquisition viable again.
What people get wrong about customer lifetime value
Some overestimate by ignoring churn or blending segments. Others forget to adjust for margin—LTV based on revenue is just noise. Another issue: treating it as static. LTV changes as product, pricing, and support evolve. Tracking it in real time reveals what’s working—and what isn’t.
And finally: don’t just chase high LTV customers. If acquisition cost or support intensity kills margin, you’re building a fragile model. The key is balance, not bragging rights.
Value over time is how growth gets real
Customer lifetime value shifts your thinking from transactions to relationships. It reframes acquisition as investment, and retention as ROI. The best teams don’t just grow user counts—they grow value per customer. Because long-term profit isn’t a bonus—it’s the business model.
