Frequently Asked Questions
What is Customer Lifetime Value (LTV)?
LTV (or CLV) is the total profit a business can expect from a single customer over the entire relationship. It helps determine how much you can spend on customer acquisition (CAC) and which customer segments are most valuable.
What’s the difference between Revenue LTV and Profit LTV?
Revenue LTV: Total revenue from a customer (before costs).
Profit LTV: Actual profit after accounting for gross margin (COGS).
Profit LTV is what matters for business decisions — revenue can be misleading if margins are low.
What is a good LTV to CAC ratio?
LTV to CAC ratio guidelines:
– <1:1 — Unprofitable — you lose money on each customer
– 1:1 to 2:1 — Breakeven — need to improve
– 3:1 to 5:1 — Healthy — ideal range for most businesses
– >5:1 — Excellent — may be under-investing in acquisition
How can I increase Customer Lifetime Value?
Three levers (this calculator shows sensitivity):
1. Increase Average Purchase Value — upsells, cross-sells, bundles, minimum free shipping thresholds
2. Increase Purchase Frequency — subscriptions, loyalty programs, replenishment emails, SMS marketing
3. Increase Customer Lifespan — reduce churn via onboarding, win-back flows, proactive support SLAs
Rule of thumb: +10% in any one lever = roughly +10% in Profit LTV.
How do I calculate LTV for subscription businesses?
For subscription models, use:
Revenue LTV = Average Monthly Revenue per Customer × Average Customer Lifespan (months)
Profit LTV = Revenue LTV × Gross Margin %
Example: $50/month subscription, 24 month lifespan, 70% margin = $50 × 24 × 0.70 = $840 Profit LTV
