Customer Lifetime Value is a prediction of the total profit a business can expect to earn from a single customer over the entire duration of their relationship.
Formula
There are several variations depending on how detailed you want to get, but a simplified version is:
CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan
Or if you’re working with gross profit:
CLV = (Average Order Value × Number of Orders per Year × Customer Lifespan in Years) × Gross Margin
Example:
Let’s say a customer:
- Spends $60 per order
- Buys from you 6 times a year
- Remains a customer for 3 years
- And your gross margin is 40%
Then:
CLV = ($60 × 6 × 3) × 0.4 = $432
Why It Matters
- Helps set realistic marketing budgets (you can spend more to acquire high-LTV customers)
- Encourages customer retention, which is often cheaper than acquisition
- Reveals which customers bring the most long-term value, not just one-time purchases
