What Is CAC?
CAC stands for Customer Acquisition Cost. It tells you how much you spend to acquire one new customer.
For example, if you spend $5,000 on marketing and acquire 250 new customers, your CAC is $20.
That means each new customer costs you $20 to acquire.
Why CAC Matters
CAC helps you understand whether your growth is sustainable.
If your CAC is too high, your business may generate revenue but still lose money after product costs, shipping, fees and operational expenses.
This is especially important for ecommerce brands because ad costs can rise quickly as you scale.
What Is A Good CAC?
A good CAC depends on your:
- Average order value
- Gross margin
- Repeat purchase rate
- Customer lifetime value
- Product cost
- Shipping and payment fees
As a simple rule, lower CAC gives you more room to scale profitably.
For many ecommerce brands, CAC should ideally stay below 30–50% of average order value, depending on margins.
CAC vs AOV
CAC should always be compared against Average Order Value.
If your CAC is close to or higher than your AOV, your first order is likely unprofitable unless you have strong repeat purchases or backend revenue.
The real question is not just:
“What is my CAC?”
It is:
“Can I afford this CAC after all costs?”
