What Is a Good Customer Acquisition Cost?
A good customer acquisition cost (CAC) is at most one-third of a customer's lifetime value (LTV). For most small businesses, a healthy CAC ranges from $10-$50 for low-ticket consumer goods to $200-$1,000+ for high-ticket services. The LTV-to-CAC ratio of 3:1 is the industry standard target.
The LTV-to-CAC framework
There's no universal 'good CAC' number because it depends entirely on what each customer is worth over their lifetime. The widely-used benchmark is a 3:1 LTV-to-CAC ratio. If a customer is worth $300 to your business over their lifetime, you can afford to spend up to $100 to acquire them. Below 3:1, you're working too hard to grow. Above 5:1, you may be under-investing in acquisition.
Calculate LTV as: average order value × average orders per year × average customer lifespan in years × gross margin. Calculate CAC as: total marketing spend ÷ new customers acquired in the same period.
Industry benchmarks
Restaurants: $10-$30 CAC, LTV often $300-$1,000. Retail (small): $20-$60 CAC, LTV $150-$800. Salons/spas: $25-$75 CAC, LTV $500-$2,500. SaaS (small): $100-$400 CAC, LTV $1,500-$10,000. Home services: $50-$300 CAC, LTV $500-$5,000. These vary widely by location, niche, and quality of marketing.
Key facts
- ▸Healthy LTV-to-CAC ratio across industries is approximately 3:1 (Bain analysis, multiple years).
- ▸Restaurants typically have CAC of $10-$30 per new diner.
- ▸B2B small business CAC is typically 5-10x higher than B2C.
- ▸Retention spend has 5-7x better ROI than acquisition spend for established businesses.
- ▸About 60% of small businesses do not formally track CAC - the ones that do grow faster.
Step-by-step
- 01Calculate your last 12 months' marketing spend.
- 02Count new customers acquired in the same window.
- 03Divide. That's your blended CAC.
- 04Calculate LTV using average order × frequency × lifespan × margin.
- 05Aim for LTV:CAC of 3:1 or better. If you're under, increase retention before scaling acquisition.
Common mistakes
- ×Only counting paid ad spend in CAC. Include all marketing costs, including labor.
- ×Comparing your CAC to a competitor's. Different LTV means different acceptable CAC.
- ×Optimizing for low CAC at the expense of growth. Sometimes spending more is right.
- ×Ignoring channel-level CAC. Blended CAC hides which channels are unprofitable.
