Summary

This lesson shows you how to replace your estimated unit economics with actual numbers. You will learn how to calculate real CAC per channel, real LTV, and how to identify which metrics need attention based on the gap between your targets and reality.

The unit economics you set during the Build phase were educated guesses. Now you have real data. This chapter shows you how to update your CAC, LTV, and payback period using actual revenue and cost figures. You will learn how to calculate these numbers cleanly, identify where the model is working and where it is not, and decide whether your current growth investment makes financial sense going forward.
