Customer Lifetime Value (CLV) is one of the most critical metrics for any growing business. It represents the total amount of money a customer is expected to spend with your business during their entire relationship with you. Knowing this number allows you to determine how much you can profitably spend on customer acquisition (CAC).
The Importance of CLV in Digital Marketing
Without a clear understanding of CLV, businesses often make the mistake of looking only at the immediate profit of a first purchase. If your acquisition cost is $50 but the first purchase only yields $40 in profit, you might think you are losing money. However, if that customer stays for 3 years and buys 4 times a year, the CLV tells a much more profitable story.
How the Calculation Works
This calculator uses the standard business formula to derive your lifetime value:
Customer Value: Average Purchase Value × Purchase Frequency.
Gross CLV: Customer Value × Customer Lifespan.
Net CLV: Gross CLV × Profit Margin Percentage.

Total Revenue
$1,000
3 Ways to Increase Your CLV
1. Upselling and Cross-selling: Increase the "Average Purchase Value" by suggesting related products or premium versions at checkout.
2. Subscription Models: Shift from one-time purchases to recurring billing to stabilize "Purchase Frequency" and extend "Lifespan."
3. Email Remarketing: Use automated email sequences to bring customers back more often, directly impacting the frequency of transactions.
