How To Calculate Customer Acquisition Cost (Cac) And Optimize Your Marketing Budget How To Calculate Customer Acquisition Cost

What is Customer Acquisition Cost (CAC)?

Customer Acquisition Cost (CAC) is the total expense incurred by a company to gain a new paying customer. It encompasses all the marketing and sales costs associated with attracting, converting, and onboarding a new client. Think of it as the price you pay to grow your customer base.

Why does CAC matter?

Customer Acquisition Cost (CAC) is a critical metric that every business should track and optimize. Here’s why CAC matters so much:

Assessing Marketing Efficiency

CAC is a vital tool for evaluating the efficiency and effectiveness of your marketing and sales efforts. By calculating the cost to acquire each new customer, you can determine if your strategies deliver a positive return on investment (ROI).

Ensuring Profitability

A high CAC relative to a customer’s lifetime value (LTV) can be a red flag for profitability. If you spend too much to acquire customers who don’t stick around long enough or generate enough revenue, your business may struggle to stay in the black.

On the flip side, a low CAC signals that your marketing and sales machine is humming along efficiently, bringing in new customers at a sustainable cost.

Forecasting and Budgeting

Understanding your CAC allows you to forecast customer acquisition expenses and set appropriate marketing budgets accurately. Knowing how much it costs to bring in each new customer, you can plan your spending and hiring needs based on your growth targets.

Attracting Investors

Investors pay close attention to CAC as a key indicator of a company’s growth potential and efficiency. A business with a low and steadily decreasing CAC demonstrates that it has a scalable, profitable model for acquiring new customers – which is very attractive to investors.

Identifying Areas for Optimization

Tracking CAC over time can reveal opportunities to optimize your marketing and sales strategies. If you notice your CAC starting to creep up, it’s a signal to dig deeper and identify areas for improvement, such as:

By monitoring CAC closely and continuously working to improve it, you can ensure that your customer acquisition efforts are efficient and effective and drive profitable growth for your business.

How to Calculate Customer Acquisition Cost (CAC):

The most straightforward way to calculate your CAC is by dividing your total sales and marketing expenses by the number of new customers acquired over a given period:

CAC = Total Sales and Marketing Expenses / Number of New Customers Acquired

For example, if your company spent $50,000 on marketing and sales in the last quarter and gained 500 new customers, your CAC would be:

$50,000 / 500 = $100 per new customer

The Fully Loaded CAC Formula

To get a more comprehensive view of your CAC, use the fully loaded formula

Fully Loaded CAC = (Marketing Expenses + Sales Expenses + Salaries + Overhead) / New Customers

This formula accounts for various expenses beyond direct ad spend, including:

  • Salaries of marketing and sales staff
  • Software and tool subscriptions
  • Freelancer and agency fees
  • Overhead costs like rent and utilities

The fully loaded CAC captures all the expenses fueling your customer acquisition efforts, providing a more accurate picture of your true costs.

Benchmarking Your CAC

Once you’ve calculated your CAC, it’s time to benchmark it against industry standards and your historical data. While there’s no universal “good” CAC, a common rule of thumb is that your Customer Lifetime Value (LTV) should be at least 3x your CAC.

Here are some average CAC benchmarks by industry, according to a study by Propeller CRM:

  • Retail: $10
  • Travel: $7
  • Consumer Goods: $22
  • Manufacturing: $83
  • Transportation: $98
  • Marketing Agency: $141
  • Financial: $175
  • Technology (Hardware): $182
  • Real Estate: $213
  • Banking/Insurance: $303
  • Telecom: $315
  • Technology (Software): $395

Keep in mind that these are averages, and your CAC may vary based on your specific niche, target audience, and marketing mix.

Optimizing Your CAC

Armed with your CAC data, it’s time to optimize for efficiency and profitability. Here are some strategies to lower your CAC and stretch your marketing dollars further:

Double Down on Your Top-Performing Channels

Analyze which marketing channels are delivering the lowest CAC and highest-quality customers. Allocate more budget to these proven winners and consider scaling back on underperforming channels.

Implement a Referral Program

Word-of-mouth is a powerful, low-cost acquisition channel. Incentivize your existing customers to refer their friends and colleagues with discounts, free upgrades, or cash rewards.

Invest in Content Marketing

Creating valuable, SEO-optimized content can attract organic traffic and establish your brand as a thought leader. While content marketing requires an upfront investment, it can pay dividends over time in the form of a lower CAC.

Continuously A/B Test and Optimize

Never stop experimenting with your ad copy, landing pages, and funnel. Incremental improvements in conversion rates can have a big impact on lowering your CAC.

Leverage Retargeting

Don’t let website visitors slip away. Implement retargeting campaigns to bring back interested prospects and guide them further down the funnel.


Mastering your Customer Acquisition Cost is like unlocking a secret weapon for business growth. By understanding the true cost of gaining each new customer, you can make informed decisions about where to invest your marketing budget for maximum impact.

Remember, CAC is just one piece of the puzzle – it’s equally important to focus on delivering an exceptional customer experience and maximizing Customer Lifetime Value.

The most successful companies are those that can efficiently acquire new customers and keep them coming back for more. So go forth and conquer the world of customer acquisition! With a data-driven approach and a commitment to continuous optimization, you’ll be well on your way to sustainable, profitable growth.

Frequently Asked Questions:

What’s the difference between CAC and CPA?

CAC measures the cost to acquire a paying customer, while Cost Per Acquisition (CPA) refers to the cost to acquire any type of conversion, such as a lead, free trial signup, or newsletter subscriber. CAC is more focused on revenue-generating customers.

How often should I calculate CAC?

It’s a good practice to calculate and track your CAC on a monthly or quarterly basis. This allows you to spot trends, measure the impact of your optimization efforts, and make data-driven decisions.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
