What is LTV?
Lifetime Value — the total revenue a customer generates over their entire relationship with your business, representing the long-term financial value of acquiring and retaining each customer.
Understanding the Details
LTV (also CLV or CLTV) estimates the total revenue you'll earn from a customer before they churn. The simplest calculation is Average Revenue Per Account × Average Customer Lifespan. A more nuanced approach factors in expansion revenue, gross margins, and discounting for time value of money. LTV is critical for evaluating acquisition investment (is this customer worth the cost to acquire them?), segmentation strategy (which segments have the highest LTV?), and retention priority (how much should you invest in keeping customers?). Customer Lifetime Value covers the concept in detail — LTV is the commonly-used abbreviation in day-to-day SaaS discussions and dashboards.
How It Works in Practice
Basic LTV calculation
Average monthly revenue of £200 × average lifespan of 36 months = £7,200 LTV. At 75% gross margin, gross profit LTV is £5,400.
Segment LTV comparison
Enterprise LTV of £50K justifies £15K CAC, while SMB LTV of £3K requires CAC under £1K for healthy economics.
LTV improvement
Reducing churn from 5% to 3% monthly increases average lifespan from 20 to 33 months, boosting LTV by 65%.
Why It Matters
LTV determines how much you can afford to spend on acquisition, which customers to prioritise, and where retention investment will have the highest return.
What People Often Get Wrong
LTV is a fixed number. Actually, it changes as retention rates, pricing, and expansion revenue evolve.
LTV should include gross revenue. Actually, LTV is more meaningful when calculated on gross margin to reflect actual profitability.
All customers have the same LTV. Actually, LTV varies significantly by segment, acquisition channel, and cohort.
