What is Customer Lifetime Value?

Customer lifetime value (LTV or CLV) is the total revenue you can expect from a single customer over the entire time they do business with you.

Here's the simple formula:

LTV = Average Purchase Value × Purchase Frequency × Customer Lifespan

So if a customer spends $50 per order, orders 4 times a year, and stays with you for 3 years:

$50 × 4 × 3 = $600 LTV

That $600 tells you how much you can afford to spend acquiring that customer and still make money.

Why LTV Matters More Than You Think

Most businesses obsess over getting new customers. They should obsess over keeping existing ones.

Here's why: acquiring a new customer costs 5-25x more than retaining an existing one. And increasing retention by just 5% can boost profits by 25-95%. Those aren't typos.

When you know your LTV, you can answer questions like:

  • How much can I spend on ads and still be profitable?
  • Should I offer a discount to keep this customer?
  • Which customers deserve VIP treatment?
  • Is my business actually sustainable?

If your LTV is lower than your CAC (cost to acquire a customer), you're losing money on every sale. That's not a business model. That's a countdown.

The LTV:CAC Ratio Explained

LTV alone doesn't tell the whole story. You need to compare it to what you spend to get that customer.

LTV:CAC Ratio = Customer Lifetime Value ÷ Customer Acquisition Cost

The benchmarks:

  • 1:1 means you're breaking even. No profit.
  • 2:1 is okay but leaves little margin for error.
  • 3:1 is the standard target for healthy businesses.
  • 5:1 or higher means you're printing money (or under-investing in growth).

Most VCs want to see at least 3:1 before they'll invest. It proves your unit economics actually work.

How to Increase Customer Lifetime Value

There are only three levers:

  1. Increase average purchase value. Upsells, bundles, premium tiers. If someone's buying, get them to buy more.
  2. Increase purchase frequency. Subscriptions, loyalty programs, regular touchpoints. Stay top of mind.
  3. Increase customer lifespan. This is retention. Keep them longer, keep their money longer.

Of these three, retention usually has the biggest impact. A customer who stays 4 years instead of 2 doubles their LTV without you spending a dime on acquisition.

What kills retention? Bad product, sure. But also: slow support, ignored emails, feeling like a number instead of a customer. The businesses with the best LTV are usually the ones that respond fastest when customers reach out.
