Frequently asked questions
What is CLV?
Customer Lifetime Value is the total revenue a business can expect from a single customer over the entire duration of their relationship.
What is a good CLV:CAC ratio?
A ratio of 3:1 or higher is generally healthy. Below 1:1 means you spend more to acquire than you earn.
How does churn rate affect CLV?
Higher churn = shorter lifespan = lower CLV. A 5% monthly churn gives an average lifespan of 20 months.
What is the difference between CLV and LTV?
They are the same metric. CLV (Customer Lifetime Value) and LTV (Lifetime Value) are used interchangeably.
Is my data private?
Yes — all calculations run in your browser. Nothing is sent anywhere.
Which mode should I use?
Simple mode is fine for most cases. Use advanced mode if you want to account for gross margin and time value of money.
