Customer Lifetime Value (LTV)
Customer Lifetime Value (LTV or CLV) is the total revenue a business can expect from a single customer account throughout their entire relationship. It's a crucial metric for understanding customer profitability and setting appropriate acquisition budgets.

Formula
LTV = Average Order Value × Purchase Frequency × Customer LifespanWhere:
Average Order Value=Average revenue per transactionPurchase Frequency=Average number of purchases per time periodCustomer Lifespan=Average duration of customer relationshipExample
Scenario
Customers spend an average of $50 per order, make 4 purchases per year, and remain customers for 3 years.
Calculation
LTV = $50 × 4 × 3 = $600Result
Your customer LTV is $600, the expected total revenue from each customer over their lifetime.
When to Use Customer Lifetime Value
- 1Determining how much you can afford to spend acquiring customers
- 2Calculating LTV:CAC ratio to assess business sustainability
- 3Identifying and prioritizing high-value customer segments
- 4Making decisions about retention vs. acquisition investment
- 5Forecasting revenue and planning growth strategies
Common Mistakes
- ✗Using revenue instead of contribution margin for profitability decisions
- ✗Not accounting for customer churn in lifespan calculations
- ✗Assuming all customers have the same LTV
- ✗Using LTV projections without validating with historical data
LTV Calculation Methods
There are several ways to calculate LTV depending on your business model:
- Historical LTV: Actual revenue from past customers - most accurate but backward-looking
- Predictive LTV: Models future behavior based on early signals
- Cohort-based LTV: Calculates LTV for groups of customers acquired together
Segmenting LTV
Not all customers are equal. Segment your LTV by acquisition channel, product line, or customer demographics to identify your most valuable customer profiles. This helps you focus acquisition efforts on attracting more high-LTV customers.
Frequently Asked Questions
What is a good LTV:CAC ratio?
A 3:1 LTV:CAC ratio is generally considered healthy - meaning your customer is worth 3x what you spent to acquire them. Below 1:1 is unsustainable, and above 5:1 might indicate under-investment in growth.
Should I use revenue or profit for LTV?
For acquisition decisions, use gross margin LTV (revenue minus direct costs). This gives a more accurate picture of how much you can afford to spend on acquisition while remaining profitable.
How do I calculate LTV for a subscription business?
For subscriptions: LTV = Monthly Revenue × Average Customer Lifetime. Or use LTV = Monthly Revenue ÷ Monthly Churn Rate for a quick estimate.
How can I increase LTV?
Increase average order value through upselling and cross-selling, improve purchase frequency through engagement and retention programs, extend customer lifespan by reducing churn, and focus on acquiring higher-quality customers.
