LTV:CAC Benchmarks (SaaS / D2C)

Less than 1:1 : Lethal. You lose money on every customer acquired. Absolute disaster.
1:1 to 3:1 : Meh. You are just churning money without long term operating leverage.
3:1 : The Gold Standard. You make 3x more than you spend. Highly investable.
5:1+ : Excellent! But you may be under-investing in marketing. Spend more to grow faster.
