Know your acquisition cost

Enter your marketing spend and customer data to calculate CAC and optimize your acquisition strategy.

The CAC formula
CAC = Marketing Spend / Customers Acquired

What to include in CAC

For accurate CAC, include all costs related to acquiring customers—not just ad spend.

Include these costs

  • Paid advertising (Google, Facebook, LinkedIn, etc.)
  • Sales team salaries and commissions
  • Marketing team salaries
  • Content creation and SEO costs
  • Marketing software and tools
  • Agency fees

Don't include

  • Product development costs
  • Customer support (post-acquisition)
  • General administrative costs
  • Infrastructure and hosting
  • Customer success (retention focused)

CAC benchmarks by industry

CAC varies wildly by industry and business model. Here are typical ranges.

SaaS (SMB)
$200-$500

Self-serve, lower touch

SaaS (Enterprise)
$5,000-$20,000

High touch, long sales cycle

Ecommerce
$10-$50

Varies by product price

Fintech
$100-$500

Regulated, trust-dependent

Consumer Apps
$1-$5

High volume, low intent

B2B Services
$500-$2,000

Relationship-driven

These are rough averages. Your CAC should always be evaluated relative to your LTV.

How to reduce your CAC

Improve targeting

Better audience targeting means less wasted ad spend. Use lookalike audiences, refine your ICP, and focus on channels where your customers actually are.

Optimize conversion rates

A higher conversion rate means more customers from the same spend. A/B test landing pages, improve your funnel, and reduce friction in signup.

Build referral loops

Referral customers have near-zero CAC. Build sharing mechanics, referral programs, and incentives that turn customers into acquisition channels.

Invest in organic

SEO, content marketing, and community building have high upfront costs but lower marginal CAC over time. They compound while paid doesn't.

Lower your CAC with viral waitlists

Waitlister's built-in referral system helps you acquire customers through word-of-mouth—the lowest CAC channel.

Do not sleep on this tool. I can have a CTA page up in 10-15 mins that encourages others to share via a soft referral system.
