Customer Lifetime Value (LTV)

LTV is the total revenue a single customer generates over their entire relationship with your business. For SMB service businesses, LTV is usually 3-10x the first transaction value (because of repeat purchases, referrals, upsells). Knowing LTV is required to set your customer acquisition budget.

The longer version

Most SMBs underestimate LTV because they only count the first sale. A dental patient at $500 per cleaning becomes a $2,000-$5,000 lifetime customer when you count repeat visits + family members. A roofing customer at $8,000 becomes $15,000+ when you count repairs + referrals. Calculating real LTV unlocks larger marketing budgets and clearer ROI on AI investments. Many AI implementations specifically target increasing LTV (win-back bots, follow-up systems, loyalty automation).

Common questions

How do I calculate LTV?

Average transaction value times average number of transactions times average customer lifespan in years.

Why does LTV matter for AI ROI?

Because AI improves retention + repeat purchase rate. Even a 5% lift in retention compounds enormously on LTV.

What is a healthy LTV-to-CAC ratio?

3:1 minimum. 5:1 or higher means you can afford to spend more on acquisition.
