Ehsan's Analysis
E-commerce LTV:CAC has a uniquely punishing dynamic: CAC is paid upfront (day 0) while LTV accumulates over 12-36 months of repeat purchases. With Meta and Google CPAs rising 15-25% annually, many DTC brands now have LTV:CAC ratios below 2x — meaning they never fully recoup acquisition costs. The brands that survive this math share one structural advantage: a subscription or auto-replenishment model that converts the first purchase into guaranteed repeat revenue. Dollar Shave Club's LTV:CAC at acquisition by Unilever was approximately 5x — not because individual razor purchases were high-margin, but because 65% of customers maintained subscriptions for 18+ months. Without subscription, the same product has an estimated LTV:CAC of 1.5x. If your e-commerce LTV:CAC is below 3x and you do not have a repeat-purchase mechanism, you are running a charity, not a business.
