What Is a Customer Lifetime Value (CLV) Calculator?
A Customer Lifetime Value calculator estimates the total revenue a business can expect from a single customer over the entire relationship. CLV is one of the most important metrics for understanding customer profitability and making informed decisions about marketing spend, customer acquisition, and retention strategies.

The CLV Formula
The simple CLV formula is: CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan. This gives a straightforward estimate of how much revenue each customer will generate. While more advanced models incorporate discount rates and profit margins, this basic formula provides a quick, useful benchmark.
CLV = Avg Value × Frequency × Lifespan
Frequently Asked Questions
Why is CLV important?
CLV helps you determine how much you can afford to spend on acquiring a customer. If your CLV is $3,000, spending $300 on acquisition (a 10:1 LTV:CAC ratio) is very healthy. It also informs retention investments.
What is a good CLV?
There is no universal benchmark. The key is that CLV should be significantly higher than your Customer Acquisition Cost (CAC). A ratio of at least 3:1 (CLV:CAC) is generally considered healthy for most businesses.
