CAC Calculator

Calculate your customer acquisition cost and optimize your spending

Know exactly how much you’re spending to acquire each customer. Customer Acquisition Cost (CAC) is the key metric that reveals whether your growth is sustainable and helps you make data-driven decisions about your marketing and sales investments.

Why calculate CAC?

Track, optimize, and scale your customer acquisition efforts with confidence. Understanding your customer acquisition cost helps you identify profitable channels, optimize your spending, and build sustainable growth strategies.

Validate growth channels

Stop guessing which acquisition channels work. CAC calculation reveals your most cost-effective channels, helping you double down on what brings customers at the right price while cutting underperforming investments.

Control your burn rate

Make every growth dollar count. By measuring CAC consistently, you’ll spot expensive acquisition channels early and redirect resources to more efficient methods before they drain your budget.

Plan strategic growth

Take the uncertainty out of scaling. With clear CAC metrics for each channel, you can confidently forecast growth costs, plan expansion strategies, and maintain profitability as you scale.

FAQ

A good CAC varies by industry and business model. Generally, you want your customer lifetime value (LTV) to be at least 3 times your CAC. For example, if your average customer generates $300 in lifetime value, aim to keep your CAC under $100. However, higher CACs can be sustainable if you have strong customer retention and high repeat purchase rates. Focus on maintaining a healthy LTV:CAC ratio rather than hitting specific CAC numbers.

To calculate CAC accurately:

  1. Add up all acquisition costs (marketing spend, sales salaries, tools, content creation)
  2. Track the number of new customers acquired
  3. Use the formula: CAC = Total Acquisition Costs / Number of New Customers For example, if you spend $10,000 on acquisition and gain 100 customers, your CAC is $100 per customer.

Include all costs related to acquiring customers:

  • Advertising spend
  • Marketing tools and software
  • Sales team salaries and commissions
  • Content creation costs
  • Agency or freelancer fees
  • PR and events
  • Portion of overhead dedicated to acquisition Missing costs can make your CAC appear artificially low and lead to poor decisions.

Monitor CAC monthly for quick-converting businesses and quarterly for longer sales cycles. Track it by channel and campaign to identify what’s working. For seasonal businesses, compare year-over-year periods. Most importantly, allow enough time to capture the full acquisition cycle – rushing measurements can lead to incomplete data.

CAC can increase for several reasons:

  • Rising advertising costs
  • Increased market competition
  • Expanding to new customer segments
  • Seasonal changes in buying behavior
  • Marketing channel saturation
  • Changes in platform algorithms
  • Inefficient marketing spend Regular monitoring helps identify causes early.

To reduce your CAC:

  • Optimize conversion rates
  • Test different audience segments
  • Improve targeting precision
  • Focus on customer retention
  • Build referral programs
  • Leverage content marketing
  • Automate marketing processes Always balance CAC reduction with maintaining acquisition quality.

Customer Lifetime Value (LTV) and CAC work together to indicate business health. Aim for an LTV:CAC ratio of at least 3:1, meaning each customer generates 3 times more value than their acquisition cost. This ensures enough margin to cover operating costs and generate profit. Higher ratios (5:1 or better) indicate stronger unit economics and growth potential.

Different channels typically have varying CAC:

  • Organic search: Lower CAC but takes time
  • Paid ads: Higher immediate CAC but scalable
  • Referrals: Often lowest CAC but harder to scale
  • Content marketing: Higher upfront cost but decreasing CAC over time
  • Social media: Varies by platform and audience Track channel-specific CAC to optimize your marketing mix.
