Customer Acquisition Cost (CAC) is how much you spend to acquire one new customer. As ad costs rise, reducing CAC while maintaining quality is essential for profitability.
What Is CAC?
CAC Formula
CAC = Total Marketing Spend ÷ New Customers Acquired
Track CAC by channel with marketing analytics to see which sources are most efficient.
8 Strategies to Reduce CAC
1. Improve Ad Targeting
Better targeting means less wasted spend. Focus on high-intent audiences and use lookalikes from best customers.
2. Optimize Landing Pages
Higher conversion rates mean lower effective CAC. See our CRO guide.
3. Leverage Organic Channels
SEO, content marketing, and social media have lower marginal costs than paid ads.
4. Build Email and SMS Lists
Email marketing converts at near-zero marginal cost.
5. Implement Referral Programs
Turn customers into acquisition channels with rewards for referrals.
6. Retarget Efficiently
Retargeting converts at higher rates than prospecting, lowering blended CAC.
7. Test Creative Constantly
Better creative = better CTR = lower CPCs = lower CAC.
8. Focus on LTV, Not Just CAC
Sometimes higher CAC is acceptable if you increase customer lifetime value.
