LTV and AOV: why contribution-profit LTV beats raw LTV

Lifetime value is how much a customer spends across their life with your business. Like average order value, it is an output metric — the result of other decisions rather than a lever you pull directly. Pricing is one of those decisions: higher prices mean each purchase contributes more to that 12-month cycle.

Moving average order value

BottleKeeper was deliberate about bundling to move as much value as possible through a single order. The first unit sold at full price. A two-pack went for $75 instead of $80. A three-pack brought the third unit down to a $30 price point.

These were tested constantly and cleanly, without mixing variables, and wherever the testing landed generally became the permanent price structure for that stage of the product's life. Complementary products at checkout are another route, and there is no shortage of Shopify apps that handle it.

Why both metrics matter to marketing

Higher AOV and LTV mean the same ad dollar generates more revenue per customer over time. That means you can afford to acquire more customers at a higher cost and remain profitable — your ROAS improves as a result of improving these metrics, without touching a campaign.

The caveat that makes LTV useful

Every one of these metrics becomes a vanity metric the moment you lose the context around it.

• •A million dollars in net profit sounds excellent — unless you are doing a billion in revenue, in which case it is horrific.
• •A 10% conversion rate is incredible — unless the business does $3,000 a year, in which case it means nothing.
• •A $10,000 lifetime value sounds enormous — but if your variable margin including ad spend is 98%, that customer generates $200 of contribution profit against it.
