A good LTV is $168 average. Top performers achieve 3x+ of CAC.

How do I increase customer lifetime value?

Focus on three levers: increase AOV (bundles, upsells), increase purchase frequency (subscriptions, loyalty programs, email marketing), and extend customer lifespan (improve product quality, customer service, and post-purchase experience).

What's the difference between LTV and CLV?

They're the same metric—LTV (Lifetime Value) and CLV (Customer Lifetime Value) are used interchangeably in ecommerce. Some analysts use CLV for the calculation and LTV as shorthand.

How long should I wait to calculate accurate LTV?

You don't need to wait years. Use predictive LTV based on early customer behavior—first 90-day purchase patterns strongly predict long-term value. Many analytics tools can model this for you.

Customer Lifetime Value

Q: How do you calculate LTV?

CLV = Average Order Value × Purchase Frequency × Average Customer Lifespan

The total revenue a business expects to earn from a single customer over the entire duration of their relationship.

Formula

CLV=Average Order Value × Purchase Frequency × Average Customer Lifespan

Example: LTV = $45 × 12 orders/year × 1.5 years = $810 revenue LTV (or $486 profit LTV at 60% margin)

Why It Matters

LTV is the single most important metric for sustainable growth. It tells you exactly how much you can spend to acquire a customer while remaining profitable. Brands with high LTV can outbid competitors for ads, invest more in product quality, and weather economic downturns because each customer relationship compounds over time.

Formula

CLV=Average Order Value × Purchase Frequency × Average Customer Lifespan

Example: LTV = $45 × 12 orders/year × 1.5 years = $810 revenue LTV (or $486 profit LTV at 60% margin)

Practical Example

Scenario

A premium coffee subscription brand has customers who order $45/month on average, typically stay subscribed for 18 months, with a 60% gross margin.

Calculation

LTV = $45 × 12 orders/year × 1.5 years = $810 revenue LTV (or $486 profit LTV at 60% margin)

Result

With an $810 LTV, they can afford up to $270 CAC (3:1 ratio) and still be profitable. This gives them significant room to invest in customer acquisition.

In-Depth Explanation

CLV determines how much you can afford to spend on acquisition while remaining profitable. Average ecommerce CLV is approximately $168.

Pro Tips

1Calculate LTV by acquisition cohort and channel. Customers from organic search often have 40% higher LTV than those from paid social.
2Use a 12-24 month lookback for LTV calculations to get actionable data, rather than waiting for 'true' lifetime data.
3Track profit-based LTV, not just revenue LTV. A $500 revenue customer with 30% margins is worth less than a $400 customer with 70% margins.
4Segment LTV by first product purchased—certain entry products create more valuable long-term customers.

Common Mistakes to Avoid

Using average customer lifespan instead of median—a few long-term customers can skew averages and overstate typical LTV.

Not accounting for discounts and returns in LTV calculations, which can inflate the number by 15-25%.

Calculating LTV once and forgetting it. LTV changes with product mix, pricing, and retention efforts—recalculate quarterly.
