- CAC. The Only Marketing Metric That Actually Matters
CAC. The Only Marketing Metric That Actually Matters
"What's your cost per lead?"
Wrong question.
"What's your click-through rate?"
Still wrong.
The only number that matters in your marketing is CAC, Cost to Acquire a Customer.
Let me explain why this one metric separates businesses that scale from those that struggle:
VANITY METRICS:
• Cost per lead: $25
• Click-through rate: 4.2%
• Conversion rate: 2.1%
• Result: Impressive screenshots, empty bank account
MONEY METRIC:
• Cost to Acquire Customer (CAC): $100
• Customer Value: $500
• ROI: 400%
• Result: Predictable, scalable revenue machine
Here's what this looks like in practice:
You're spending $3,000 monthly on ads. Your service costs $500.
If your CAC is $100, you're acquiring 30 customers monthly ($15,000 revenue). If your CAC is $300, you're acquiring 10 customers monthly ($5,000 revenue). If your CAC is $600, you're acquiring 5 customers monthly ($2,500 revenue).
Notice how the same ad spend produces wildly different results based on this one metric?
But here's what most marketers won't pay attention to and tell you. You can't calculate your true CAC in two weeks.
You need 90 days minimum.
Why? Because marketing follows patterns that only emerge with sufficient data:
MONTH 1:
• Learning phase
• Algorithm testing
• High CAC
MONTH 2:
• Optimization begins
• Patterns emerge
• CAC improves
MONTH 3:
• System stabilizes
• Predictable results
• True CAC revealed
Once you know your CAC, scaling becomes simple math:
If $1,000 spent = 40 leads = 2 customers ($100 CAC) Then $2,000 spent = 80 leads = 4 customers (same CAC)
Want to improve your CAC without spending more? Add qualification steps to your funnel.
You'll get fewer leads, but higher quality: $1,000 spent = 20 leads = 5 customers ($50 CAC)
This is how businesses scale predictably, they know exactly what a customer costs to acquire, then they simply buy more customers.
Stop obsessing over cost per lead. Start tracking your CAC.
Because when you know what it costs to acquire a customer, you're no longer marketing—you're printing money.
