Customer Acquisition Cost (CAC)
What you pay, all-in, to win one new customer.

Cohort Revenue
What one signup cohort is really worth as retention decays month over month.
LTV : CAC Ratio
How many dollars of lifetime profit you get back for each dollar spent on acquisition.
MRR / ARR Forecast
Project where your recurring revenue lands if your current growth rate holds.
