When it comes to building a thriving business, marketing isn’t just about creativity—it’s about numbers. At Entrepreneurial Business School, one of the first principles we teach when it comes to marketing strategy is simple but powerful: marketing is math.
One of the most important metrics in your marketing toolkit is your acquisition cost. Understanding this figure—how much you spend to acquire a customer or lead—can transform the way you approach your marketing budget, campaigns, and ultimately, your business growth.
What is Acquisition Cost?
Customer Acquisition Cost (CAC) is the total amount of money you spend on marketing (and often sales) to acquire a new customer. It can also be applied to leads, depending on what stage of the sales funnel you’re measuring.
For example, if you spend $1,000 on a campaign and it brings in 10 customers, your acquisition cost is $100 per customer. If another strategy costs you $11,000 and brings in 100 customers, your cost per customer is $110. Knowing this allows you to compare your strategies and double down on what works best.
Why It Matters
Measuring acquisition cost isn’t optional—it’s essential. Without it, you’re flying blind when it comes to marketing. Once you know what it costs to acquire a customer across different strategies, you can:
- Identify your most efficient marketing channels
- Allocate your budget more effectively
- Eliminate or refine underperforming strategies
- Forecast your growth with greater accuracy
The question we often ask our clients is this: Are you measuring your acquisition cost per marketing strategy?
If not, it’s time to start.
Is $100 a Good Acquisition Cost?
Let’s break this down with a quick example. Suppose you spend $500 on a campaign and get 5 customers. That’s a $100 acquisition cost per customer. But is that good?
The answer: It depends.
If your average profit per customer is $2,000, then absolutely—spending $100 to make $2,000 is a great return. In fact, you’d likely want to invest in that campaign as often as possible, provided your business can keep up with the demand.
However, if your profit per customer is only $50, spending $100 to acquire them puts you at a loss. This is why acquisition cost must always be viewed in the context of your profit per customer.
Your Allowable Acquisition Cost
This brings us to another crucial concept: allowable acquisition cost.
This is the maximum amount you’re willing to spend to acquire a customer while still remaining profitable. To calculate it, consider:
- Your average gross margin per customer or sale.
- The percentage of that margin you’re comfortable reinvesting in acquiring new customers.
Marketing is an Investment, Not an Expense
Once you understand acquisition cost and allowable acquisition cost, marketing transforms from a risky expense into a calculated investment. Each dollar spent becomes a strategic move aimed at buying future revenue.
Remember:
- Know your numbers.
- Monitor your strategies.
- Invest where the return is measurable and scalable.
