The LTV calculator estimates how much total revenue a customer will generate over their entire relationship with your business. Customer lifetime value is one of the most important metrics for SaaS companies, e-commerce stores, and any subscription business because it tells you how much you can afford to spend acquiring a customer while staying profitable. This tool supports three calculation methods: a simple model based on average revenue and lifespan, an e-commerce model using order value and purchase frequency, and a discounted cash flow model for SaaS businesses that accounts for churn and time value of money. If you know your customer acquisition cost, the calculator also shows your LTV:CAC ratio — the benchmark most investors use to evaluate unit economics.

How to calculate LTV

Simple: LTV = Average Monthly Revenue × Customer Lifespan × Gross Margin E-commerce: LTV = Average Order Value × Purchase Frequency × Customer Lifespan × Gross Margin Discounted: LTV = (Monthly Revenue × Gross Margin) ÷ (Churn Rate + Discount Rate) Example: $99/mo × 24 months × 70% margin = ~$1,663 LTV. With $500 CAC, LTV:CAC = 3.3:1 (healthy).

FAQ

What is a good LTV:CAC ratio?expand_more
3:1 or higher is generally considered healthy. Below 3:1 can indicate inefficient acquisition, while above 5:1 may mean you're under-investing in growth.
What's the difference between LTV and CLV?expand_more
They refer to the same concept: Customer Lifetime Value. Both abbreviations are commonly used.
How do I improve LTV?expand_more
Reduce churn, increase ARPU through upsells, and extend customer lifespan through better onboarding and customer success.
Should I use simple or discounted LTV?expand_more
Use the simple model for quick estimates. Use discounted LTV for financial planning and investor decks because it accounts for churn and time value of money.
What LTV:CAC ratio do investors want to see?expand_more
Many investors expect at least 3:1. 5:1 is considered strong for Series A and later, depending on your market and growth stage.
