Customer Lifetime Value (LTV)
Customer Lifetime Value (LTV or CLV) is the total revenue, or profit, a business expects to earn from a single customer across the entire relationship. It estimates long-term worth rather than a one-time sale, helping teams judge how much they can afford to spend acquiring and retaining each customer.

How do you calculate Customer Lifetime Value?
A common formula is LTV = Average Revenue Per Account x Gross Margin x Customer Lifetime, where lifetime is often estimated as 1 divided by the churn rate. For a subscription business, if a customer pays $50 per month at 80% gross margin and churns at 5% monthly, the average lifetime is 20 months, giving an LTV of $50 x 0.80 x 20 = $800. Revenue-based LTV ignores margin; profit-based LTV is more conservative and more useful for unit economics. More advanced models discount future revenue to present value and segment by cohort, plan, or acquisition channel, since high-value customers often behave very differently from the average.
Why does the LTV:CAC ratio matter?
LTV is most useful next to Customer Acquisition Cost (CAC), the fully loaded cost of winning a customer. The LTV:CAC ratio reveals whether growth is sustainable. A widely cited benchmark for SaaS is roughly 3:1: you recover at least three dollars of lifetime value for every dollar spent acquiring a customer. A ratio near 1:1 means you are barely breaking even, while a very high ratio can signal underinvestment in growth. Teams also watch the CAC payback period, the months needed to recoup acquisition cost. Together these metrics guide budget allocation, channel choices, and how aggressively to scale spend.
How can teams increase Customer Lifetime Value?
Because lifetime scales inversely with churn, retention is usually the highest-leverage lever: improving onboarding, support, and product fit keeps customers paying longer. Expansion revenue through upsells, cross-sells, and usage-based growth raises average revenue per account, while better targeting of your ideal customer profile attracts accounts that stay and spend more. A CRM helps by centralizing the renewal, usage, and engagement signals that predict churn and expansion. Orphica, an AI-native CRM, can surface these patterns across companies and deals so teams act before value leaks rather than after a customer has already left.
Frequently asked questions
What is the difference between LTV and CLV?+
They refer to the same concept: the total value a business expects from a customer over the relationship. LTV (lifetime value) and CLV (customer lifetime value) are used interchangeably; some teams write CLTV. There is no methodological difference, only naming preference.
Should LTV be based on revenue or profit?+
Profit-based LTV, which multiplies revenue by gross margin, is more accurate for unit-economics decisions because it reflects what you actually keep. Revenue-based LTV is simpler and common in early reporting, but it can overstate how much you can afford to spend on acquisition.
What is a good LTV to CAC ratio?+
For most SaaS and subscription businesses, an LTV:CAC ratio around 3:1 is considered healthy. Near 1:1 suggests you are spending too much to acquire customers, while a ratio far above 3:1 may indicate you are underinvesting in growth and leaving market share on the table.
How does churn affect Customer Lifetime Value?+
Churn directly shortens the expected customer lifetime, since lifetime is often estimated as one divided by the churn rate. Lowering churn lengthens the relationship and compounds revenue, which is why retention is typically the most effective way to raise LTV.
