Customer Lifetime Value Calculator

Calculate Customer Lifetime Value (CLV/LTV) for any business model. Supports both simple calculation and SaaS subscription models with churn-based projections.

About this tool

Customer Lifetime Value tells you how much revenue you can expect from a single customer over your entire relationship. It's essential for setting acquisition budgets, optimizing retention strategies, and forecasting revenue. For subscription businesses, CLV is directly tied to churn — reduce churn by even 1% and watch lifetime value soar. Use our CAC calculator to compare acquisition cost against lifetime value (aim for a 3:1 LTV:CAC ratio). Track your churn rate to understand what drives CLV changes, and measure email conversion rates to optimize your acquisition funnel.

Frequently Asked Questions

What is Customer Lifetime Value (CLV)?

Customer Lifetime Value (CLV or LTV) is the total revenue a business can expect from a single customer account over the entire duration of their relationship. It considers purchase frequency, average order value, and how long customers typically stay. CLV helps you understand how much you can afford to spend on acquiring and retaining customers.

How is CLV calculated for SaaS businesses?

For SaaS, CLV = Average Revenue Per User (ARPU) ÷ Monthly Churn Rate. For example, if your ARPU is $100/month and monthly churn is 5%, CLV = $100 ÷ 0.05 = $2,000. You can also factor in gross margin: CLV = (ARPU × Gross Margin %) ÷ Churn Rate. This gives you the profit-adjusted lifetime value.

What is a good LTV:CAC ratio?

A 3:1 LTV:CAC ratio is considered the gold standard — each customer generates 3x more value than it costs to acquire them. Below 1:1 means you're losing money on every customer. Between 1:1-3:1 suggests room for improvement. Above 5:1 might mean you're under-investing in growth and could afford to spend more on acquisition.

How does churn rate affect CLV?

Churn has an outsized impact on CLV. Reducing monthly churn from 5% to 4% increases average customer lifetime from 20 to 25 months — a 25% increase in CLV. Even small churn improvements compound significantly. That's why retention-focused email campaigns often have the highest ROI of any marketing activity.

What's the difference between simple CLV and SaaS CLV?

Simple CLV multiplies average purchase value × purchase frequency × customer lifespan — it works for any business with repeat purchases (e-commerce, retail, services). SaaS CLV divides ARPU by churn rate, which is more accurate for subscription businesses since churn directly determines how long customers stay. Use simple for variable-purchase businesses and SaaS for subscription models.

How can I increase Customer Lifetime Value?

Key strategies include: reducing churn through better onboarding and engagement (automated email sequences help here), increasing average order value through upselling and cross-selling, improving purchase frequency through targeted campaigns, expanding accounts through add-ons and upgrades, and building loyalty through personalized communication and rewards.

Should I use gross margin in CLV calculations?

Yes, gross-margin-adjusted CLV gives a more accurate picture of profitability. Revenue-based CLV can be misleading if your margins are low. For example, if CLV is $10,000 but gross margin is 20%, the actual value is $2,000. This matters significantly when comparing CLV to CAC — you need profitable customers, not just high-revenue ones.
