What is Customer Lifetime Value (CLV), and how do you improve it?

Traffic is up. Conversion is solid. But revenue feels harder to grow than it should. For a lot of e-commerce merchants, that gap comes down to one thing: customers aren’t coming back.

Repeat customers spend 67% more than new customers on average, yet most merchants allocate most of their budget to acquiring people who’ve never bought from them before. If your buyers aren’t coming back after the first order, no amount of traffic growth will fix your revenue problem.

That’s where customer lifetime value (CLV) comes in. Rather than measuring what a customer spends on a single transaction, CLV captures the total revenue they generate across their entire relationship with your brand. It’s the metric that tells you whether your business is building something sustainable.

Understanding CLV, knowing how to calculate it, and knowing which levers move it are the foundations of smarter growth.

What is Customer Lifetime Value?

Customer Lifetime Value (CLV) is the total net revenue a business can expect from a single customer over the entire duration of their relationship. It shifts the focus from transaction-level thinking (“what did this customer spend today?”) to relationship-level thinking (“what is this customer worth to us over the next three years?”).

That shift matters enormously for how you allocate marketing spend, how you think about customer acquisition costs, and which retention investments are worth making.

CLV is particularly critical for e-commerce businesses, where customer acquisition costs are high, and most of the profit from a customer relationship comes from repeat purchases, not the first order. This is especially true in high-consideration categories like consumer electronics, home and furniture, jewelry, and retail, where purchase cycles are longer, and each returning customer represents significant incremental revenue.

The Customer Lifetime Value Calculation

There are several versions of the CLV formula, ranging from simple to sophisticated. For most merchants, the most practical starting point is the basic model:

CLV = Average Order Value × Purchase Frequency × Customer Lifespan

Breaking each component down:

• Average order value (AOV): The average amount a customer spends per transaction
• Purchase frequency: How many times a customer buys within a given period (typically one year)
• Customer lifespan: How long, on average, a customer continues to buy from you before churning

So, if your average customer spends $200 per order, places three orders per year, and stays for four years, your CLV is $2,400.

For a more precise view, some businesses factor in gross margin to arrive at a profit-based CLV:

CLV = (Average Order Value × Purchase Frequency × Customer Lifespan) × Gross Margin %

This version gives you the actual profitability per customer, not just gross revenue, which is what you need when comparing CLV to customer acquisition cost (CAC).

The biggest drivers of Customer Lifetime Value

Understanding how to increase customer lifetime value starts with understanding what drives it. CLV is a product of three things: how much customers spend per order, how often they come back, and how long they keep coming back.

Average Order Value

Higher AOV directly increases CLV, and one of the most effective ways to raise it is giving customers more flexibility in how they pay. When customers can split a large purchase into monthly installments they’re more willing to buy the full version, the premium bundle, or the complete set rather than a partial order that fits a tighter budget.

Purchase frequency and repeat purchase behavior

How often a customer returns is heavily influenced by their experience with your brand. That includes product quality, customer service, and shipping, but also the checkout experience itself. A checkout that’s fast, familiar, and friction-free creates a positive association with buying from you.

Customer retention

Every customer lost after one or two purchases represents not just future revenue gone, but the acquisition cost you already spent to get them there.

Retention is shaped by product quality, post-purchase experience, and loyalty programs, but also by something less obvious: whether your checkout is working for you or against you. Traditional BNPL platforms promote competitor products to your customers at the exact moment they’re buying from you. That’s not a payment experience; it’s a competitor acquisition channel running through your own checkout.

How to increase Customer Lifetime Value 

There’s no single lever that moves CLV; it’s a compound metric, and improving it requires addressing multiple touchpoints across the customer journey. Here are the most impactful areas to focus on.

Own the customer relationship 

One of the fastest ways to erode CLV is to let a third party take ownership of your customer relationship at checkout. When a BNPL provider handles your checkout under their own brand, they capture the customer data, control the communication, and use your shoppers to grow their own marketplace, including promoting your competitors.

White-label installment solutions keep your brand front and center throughout the payment experience. You keep the customer data, control the post-purchase communication, and build loyalty to your brand rather than to a payment provider. That’s a direct CLV driver: customers who feel a consistent relationship with your brand are more likely to return.

Invest in post-purchase experience

The period immediately after a purchase is one of the highest-leverage windows for CLV improvement. Order confirmation communications, delivery updates, onboarding content for complex products, and proactive customer service all signal to a customer that the relationship doesn’t end at checkout. Merchants who invest in this window consistently see higher repeat purchase rates. 

Segment customers by CLV and treat them differently

Not all customers are equal in terms of lifetime value, and treating them identically is a missed opportunity. High-CLV customers deserve priority service, exclusive offers, and early access to new products. At-risk customers, those who purchased once but haven’t returned, benefit from targeted re-engagement. Segmenting your email and CRM activity by CLV or purchase history is one of the most efficient ways to improve the metric across your entire base.

Reduce checkout friction

Every point of friction in the checkout process is a potential exit. Application steps, credit checks, slow approvals, and redirects all create hesitation at the exact moment a customer is ready to buy. The faster and more seamless the checkout, the higher the conversion rate, and the better the first impression that sets the tone for a long-term relationship.

Card-linked installments remove this friction by using the credit customers already have. No application, no credit check, no new loan, just an additional step to choose how many installments they want. That’s a fundamentally different experience from traditional BNPL, which requires customers to open a new line of credit at checkout.

Where to start with getting the checkout right

Many of the CLV drivers above, higher AOV, stronger repeat purchase rates, better brand loyalty, trace back to a single moment in the customer journey: checkout. It’s where buying decisions are finalized, where first impressions are cemented, and where most merchants are unknowingly losing value.

Splitit’s card-linked installment solution addresses several of these levers at once. By letting customers split purchases into monthly payments using their existing credit card with no application, no credit check, and no new loans. Splitit removes the friction that causes drop-off and enables larger basket sizes. It also works across every sales channel through omnichannel installments, so whether your customers are buying online, in-store, or over the phone, the experience is consistent. Because it’s fully white-label, the experience stays branded as yours throughout, which means every installment payment reinforces loyalty to your business rather than to a third-party payment platform.

The result: higher AOV, a frictionless first experience that encourages repeat visits, and a customer relationship that stays where it belongs: with you.

If improving CLV is the goal, the checkout is the most efficient place to start.

What a good Customer Lifetime Value looks like in e-commerce

CLV benchmarks vary enormously by category, price point, and business model. A furniture retailer with a long replacement cycle will have very different CLV dynamics than a skincare brand with high replenishment frequency.

• A CLV:CAC (Customer Acquisition Cost) ratio above 3:1 is generally healthy. 
• Repeat purchase rate above 25–30% is strong for many e-commerce categories, though it varies significantly by industry.
• Average purchase frequency above 2x per year indicates meaningful loyalty in moderate-frequency categories, but expectations differ significantly depending on the product.

If you’re below these benchmarks, the first question to ask isn’t “how do we improve our loyalty program?” but rather “where in the customer journey are we losing people?”. Checkout is often the answer, either through friction, declines, or a payment experience that doesn’t reflect your brand.
