Customer Acquisition Cost (CAC) is the total cost of winning a new customer, including marketing, advertising, sales operations, and creative production.

What is a good LTV:CAC ratio?

The golden standard for a sustainable business is a 3:1 LTV:CAC ratio, meaning you earn $3 for every $1 spent on acquisition. Below 1:1 means you are losing money on each customer.

What is CAC and Why Does It Matter?

Customer Acquisition Cost (CAC) is the total cost of winning a new customer, including all marketing spend, advertising, sales team commissions, software tools, and creative production. In the modern DTC and SaaS era, knowing your exact CAC is one of the most critical metrics for growth. If your CAC exceeds the lifetime value of a customer, you are effectively paying money to lose money.

The Golden Ratio: LTV:CAC

Your CAC doesn't exist in a vacuum; it must be measured against your Customer Lifetime Value (LTV).

< 1:1 (Losing Money) — You spend more to acquire a customer than you earn back from them. This is unsustainable.
3:1 (Gold Standard) — Sustainable growth. You're retaining enough value to cover costs and reinvest. The benchmark most VCs look for.
> 5:1 (Under-investing) — You could grow faster. While profitable, you're leaving market share on the table by not spending enough on acquisition.
