How to Calculate Customer Acquisition Cost (CAC) Like a Pro in 2025

Marketing Insights

Do you know how much you’re spending to acquire each customer? Your Customer Acquisition Cost (CAC) is one of the most critical metrics for understanding and optimizing your marketing efforts. Without it, you’re navigating your growth strategy blindfolded.

Businesses often spend significant resources on strategies like PPC, SEO, and Social Media Management. According to recent surveys, companies allocate over 11.5% of their revenue to marketing. Yet, marketing spend is just one piece of the CAC puzzle.

Let’s break it down step by step so you can calculate your CAC, benchmark your costs, and optimize your ROI. Ready? Let’s dive in.

What Goes Into Customer Acquisition Cost?

First, it’s essential to understand what contributes to your CAC. While marketing expenses—like Video Marketing or Content Marketing—are key components, there’s more to consider:

  • Product Costs
  • Overhead Expenses: Salaries and benefits for sales and marketing teams
  • Agency Costs: Outsourced services like Influencer Marketing
  • Research & Development: Costs associated with understanding your target market
  • Software & Tools: For campaign management, email marketing, and analytics

How Does CAC Impact Your Business?

Your CAC directly influences your profitability and growth potential. Here are three key ways it shapes your business:

#1: CAC vs. Lifetime Value (LTV)

Your goal is to maintain a healthy ratio between CAC and Customer Lifetime Value (LTV). Ideally, your LTV should be at least 3x higher than your CAC. If your CAC exceeds LTV, it’s time to reassess your strategy. Check out our blog on long-term SEO results to maximize LTV.

#2: Time to ROI

Understanding your CAC also reveals how long it takes to see a return on investment. For example, how quickly can a campaign through Email Marketing recover its costs?

#3: Attracting Investors

Investors love to see a strong CAC:LTV ratio—it signals scalability. A well-optimized CAC can set your business apart when seeking funding.

How to Calculate CAC in 5 Steps

Here’s a simple formula for calculating your CAC:

CAC = (MCC + W + S + PS + O) / CA

Let’s break it down:

  1. Define the Time Period: Are you calculating CAC for a specific campaign or your entire business?
  2. Add Up Acquisition Spend: Include marketing costs, wages, software, and any other relevant expenses.
  3. Determine New Customers: Use your CRM to find the number of new customers during the period.
  4. Apply the Formula: Divide total spend by new customers acquired.
  5. Compare CAC to LTV: Ensure your CAC is significantly lower than your LTV to maintain profitability.
