Core Business KPIs Explained: LTV, CAC, and Churn
Understanding your business's health requires more than just looking at the top-line revenue. The true story is told through your Key Performance Indicators (KPIs).
## 1. Customer Acquisition Cost (CAC) CAC represents how much you spend on sales and marketing to acquire a single new customer. It's calculated by dividing total sales and marketing expenses by the number of new customers acquired during that period.
## 2. Lifetime Value (LTV) LTV is the projected revenue a single customer will generate over the entire duration of their relationship with your business. An ideal LTV:CAC ratio is generally considered to be 3:1 or higher.
## 3. Churn Rate This is the percentage of customers who cancel their subscription or stop buying from you within a given timeframe.
