Perguntas frequentes

What does this calculator combine?
It derives CAC, LTV, payback period, and the LTV:CAC ratio in one view so you can judge whether each customer is profitable.
How is the LTV:CAC ratio interpreted?
It divides lifetime value by acquisition cost. Around 3:1 is a common healthy target; below 1:1 means a customer costs more to acquire than they return.
What makes unit economics healthy?
A LTV comfortably above CAC and a short payback period, so customers repay their acquisition cost quickly and generate profit over their lifetime.
Are my inputs kept on-device?
Yes. CAC, LTV, payback, and the ratio are all computed in your browser from the spend, revenue, and churn figures you enter, with nothing uploaded.
