Customer Lifetime Value (CLTV)

What is Customer Lifetime Value (CLTV)?

Customer Lifetime Value (CLTV) is the total revenue a business expects to earn from a customer throughout their entire relationship. It helps businesses calculate the per customer profitability in the long run and guides decisions in marketing, sales, and customer success.

How to calculate CLTV?

CLTV can be calculated by multiplying ARPU with Average Customer Lifespan (in months). You can also calculate CLTV by multiplying APV (Average Purchase Value) with PF (Purchase Frequency) and CL (Customer Lifespan).

Steps to Calculate CLTV

  • Step 1:
  • Calculate Average Purchase Value:
    Average Purchase Value = Total Revenue / Number of Purchases

  • Step 2:
  • Calculate Average Purchase Frequency:

    Average Purchase Frequency = Number of Purchases / Number of Unique Customers

  • Step 3:
  • Calculate Customer Value:

    Customer Value = Average Purchase Value × Average Purchase Frequency

  • Step 4:
  • Calculate Average Customer Lifespan:

    This is the average duration (in months or years) a customer stays active with your business.

  • Step 5:
  • Calculate CLTV:

    CLTV = Customer Value × Average Customer Lifespan

Formula to calculate CLTV

CLTV= ARPU x Customer Lifespan (in Months)

Or

CLTV= APV x PF x CL

FAQ's

Several key elements impact LTV, including customer retention, average order value, purchase frequency, and product margins. Improving any of these can increase LTV. For example, better onboarding or loyalty programs may extend a customer's lifespan; while bundling or upselling can increase average revenue.

Absolutely. LTV often varies widely across customer cohorts, by geography, acquisition channel, company size, or behavior. Segmenting LTV allows for smarter budgeting, pricing, and targeting strategies, ensuring resources are directed toward high-value customer groups.

Churn rate has a direct inverse relationship with LTV. The faster customers churn, the shorter their lifespan, and the lower their total value. Even small improvements in retention can lead to significant increases in LTV, making churn management a key lever for growth.
