A Step-by-step Guide to Calculating Customer Lifetime Value (CLV)Prepared by: Geoff Fripp, Adjunct Marketing Lecturer
The University of Sydney
http://www.clv-calculator.com/
What is Customer Lifetime Value?• Customer lifetime value is a measure of customer
profitability over time
• CLV can be defined as “a measure of a customer’s aggregate profit to the firm over the total time that the customer deals with the firm”
• CLV is calculated as a single dollar number, which summarizes the net profit/loss position of the customer’s total relationship with the firm
• It is calculated on per customer basis, but is more usually determined for an the average customer within a particular market segment• A firm will calculate multiple CLV’s for different customer
segments
Two calculation methods
The Simple CLV Formula
THE FORMULA
Annual profit contribution per customer X
Average number of years that they remain a customer
Less the initial cost of customer acquisition
WHAT INFORMATION DO WE NEED?
1. Initial cost of customer acquisition
2. Annual profit contribution per customer
3. Average customer retention rate
The CLV Calculation
We start with this information
We need to calculate this information
CLV Calculation: Step One
Average Acquisition Cost 500
Average Customer Profit pa 1000
Customer Retention Rate 75%
Customer Churn Rate 25%
Average Lifetime in Years ???
Simple CLV ???
Churn rate is 1 –retention rate
NOTE: Retention rate and churn (loss) rate always add to 100%
CLV Calculation: Step Two
SIMPLE CLV
Average Acquisition Cost 500
Average Customer Profit pa 1000
Customer Retention Rate 75%
Customer Churn Rate 25%
Average Lifetime in Years 4
Simple CLV ???
Average lifetime in years is 1 / churn rate
That is, the number of times the churn rate goes into 100%
CLV Calculation: Step Three
CLV is time/years X annual profit –acquisition cost
SIMPLE CLV
Average Acquisition Cost 500
Average Customer Profit pa 1000
Customer Retention Rate 75%
Customer Churn Rate 25%
Average Lifetime in Years 4
Simple CLV 3,500
EXAMPLE: 4 X $1,000 - $500
The Complete CLV Formula
THE FORMULA
Annual profit contribution per customer (for each year) X
The customer retention rate (for each year) less
The initial cost of customer acquisition
With each year adjusted by an appropriate discount rate
WHAT INFORMATION DO WE NEED?
1. Initial cost of customer acquisition
2. Annual revenue contribution per customer
3. Annual direct costs per customer
4. Annual customer retention rate
5. The discount rate to be used

We need to START with the figures in BLUE and we need to CALCULATE the figures in YELLOW
Customer Lifetime Value will be in the bottom-right GOLD cell

Average customer profit each year is simply average customer REVENUE less average customer COSTS

Cumulative retention rate indicates the % probability of receiving the customer’s business (revenues and costs) in future years
Cumulative retention rate is the compounding effect of losing customersWe start with 100% of customers and we keep 60% in year 2. In year 3 we
keep 65% of those remaining, which is 65% of the 60% = 39%
Full CLV Calculation: Step Three
Likely customer profit each year = Average Customer Profit (in row 3) X Cumulative Retention Rate (% probability of the
customer still buying from our firm) Example for Year 3: $600 X 39% = $234

Full CLV Calculation: Step Four
Future discount rates are compounded on a yearly basisIn this case, the discount rate is 10%
Future years are 1.1 X 1.1 = 1.21 X 1.1 = 1.33, and so on

Full CLV Calculation: Step Five
Contribution to CLV on a yearly basis is the “likely customer profit” divided by the discount rate
For example, in year 3: profit = $234 / 1.33 = $176

Full CLV Calculation: Outcomes
CLV = $332 – which is a positive number – which is greatThis means that the $500 acquisition cost has generated good profits
for the firmAs a 10% discount rate has been used, the ROI on the marketing
investment is MORE than a 10% returnPayback on customer acquisition costs is delivered in Year 3
