CAC & LTV forecasting projects customer acquisition costs and lifetime value over time to assess whether growth creates value. It moves beyond static ratios by showing how efficiency evolves as scale increases. This helps teams decide how aggressively to invest in growth.

A common benchmark for LTV/CAC ratio is 3:1, but the right level depends on margins, cash flow, and payback speed. Forecasting shows whether ratios improve or deteriorate.

CAC forecasting projects future acquisition efficiency rather than relying solely on past averages, accounting for channel mix and saturation effects.

Linking unit economics to profit and cash ensures growth decisions are financially sustainable.
