Question 1

What is Customer Lifetime Value?

Accepted Answer

A prediction of the total net profit a business can expect to earn from a customer over the entire duration of their relationship.

Question 2

What is the most common formula for CLV?

Accepted Answer

Gross CLV = Average Revenue Per Account ÷ Churn Rate, commonly used in subscription and SaaS businesses.

Question 3

Who introduced the concept of Customer Lifetime Value?

Accepted Answer

Direct marketing pioneers Robert and Kate Kestnbaum in the 1980s, later formalized in the 1988 book "Database Marketing" by Robert Shaw and Merlin Stone.

Question 4

What's the difference between Gross CLV and Net CLV?

Accepted Answer

Gross CLV uses average revenue alone; Net CLV subtracts the cost to serve a customer, giving a more accurate profitability picture.

Question 5

Why does reducing churn have such a big impact on CLV?

Accepted Answer

Because churn rate is the denominator in most CLV formulas, even small reductions produce disproportionately large increases in CLV.

Question 6

What is considered a healthy LTV:CAC ratio?

Accepted Answer

A ratio of at least 3:1 is commonly cited as healthy, meaning a customer is worth at least three times what it costs to acquire them.

Question 7

Should CLV be calculated as one company-wide number?

Accepted Answer

No. Calculating CLV by segment or cohort reveals meaningful differences that a single blended number would hide.

Question 8

What mistakes should teams avoid when calculating CLV?

Accepted Answer

Ignoring cost to serve, treating CLV as permanent, and comparing CLV without also considering CAC.

Question 9

How often should CLV be recalculated?

Accepted Answer

Regularly, since churn rates and spending patterns shift over time and a stale CLV model can mislead decisions.

Question 10

Which tools support CLV calculation?

Accepted Answer

Amplitude, Mixpanel, ChartMogul, Excel, and CRM platforms like Salesforce or HubSpot are commonly used.
