Customer acquisition cost answers what buying a customer truly costs. The honest version loads every contributing expense — ad platforms, content, sales salaries, commissions, software — not just the media bill. Teams that count only ads routinely discover their real CAC is triple the number in the deck.
CAC gains meaning in ratio to lifetime value. An expensive acquisition that pays back tenfold is cheap; a bargain CAC against thin LTV is a slow leak. Aim to understand payback period too: how many months until one customer's margin repays their acquisition.
