LTV (Lifetime Value)

What is LTV?

LTV (Lifetime Value) is the total profit or revenue generated by a customer throughout their entire business relationship. In subscription models like SaaS, automation, and AI platforms, it’s the most critical metric for understanding, predicting, and optimizing business performance.

In a nutshell: If a customer stays with you forever, how much total profit would they generate?

Key points:

• What it does: Calculate total lifetime profit from customers
• Why it’s needed: Determines long-term business growth
• Who uses it: SaaS executives, marketers, business managers, investors

Why it matters

LTV is among the best business health indicators. High LTV means customers stay long and continue paying. It determines marketing investment capacity (CAC: Customer Acquisition Cost). LTV:CAC ratios of 3:1 or higher indicate healthy businesses.

Calculation method

Standard calculation formula for SaaS and recurring revenue models:

LTV = (ARPU × Gross Margin) ÷ Monthly Churn Rate

Component explanations:

• ARPU: Average monthly revenue per user (example: $100)
• Gross Margin: Remainder after direct costs (example: 80% = 0.8)
• Monthly Churn Rate: Monthly customer loss percentage (example: 5% = 0.05)

Calculation example: With ARPU = $100, Gross Margin = 80%, Monthly Churn Rate = 5%:

LTV = $100 × 0.8 ÷ 0.05 = $1,600

Each customer generates average lifetime gross profit of $1,600.

Benchmarks

Typical LTV ranges:

• Enterprise SaaS: $10,000–$100,000+
• SMB SaaS: $1,000–$10,000
• Consumer-facing: $100–$1,000

Frequently asked questions

Q: What’s a “good” LTV:CAC ratio? A: 3:1 or higher is healthy, meaning customer acquisition spending yields three times the lifetime profit.

Q: How frequently should LTV be recalculated? A: Quarterly, or when churn rates or pricing plans significantly change.

Q: Can early-stage companies calculate LTV? A: Yes, but with lower reliability. Accurate LTV requires 12-18 months data.

Q: What’s the best LTV improvement method? A: Retention improvement is most effective. One percent churn reduction can increase LTV 10%+.
