Average Customer Acquisition Cost (CAC) By Industry: B2B Edition

Average Cac By Industry Tn

Last updated: June 7, 2024

When people ask me how to evaluate the ROI of their marketing campaigns, I tell them to start with their customer acquisition cost (CAC). That metric, along with your Customer Lifetime Value (Customer LTV, or sometimes abbreviated CLV) are your best friends in the world of B2B marketing.

By itself, your CAC tells you two things: (1) Which channels to invest more and less in; and (2) your marketing department’s strengths and weaknesses. The latter can be ascertained by comparing your CACs against industry benchmarks. 

The purpose of this article is to help you understand what a good CAC looks like within your industry. It may even be helpful to compare your CAC to adjacent industries to see if you’re within the broader range of other B2B businesses.

Calculating Your Customer Acquisition Cost

The simplest way to calculate your CAC is to divide your total marketing and sales spend by your total number of new customers, as shown in the formula below:

Cac Equation 2 1 1024x152 (1)

This calculation should be made on an annual or rolling annual basis, to account for any seasonal fluctuations in customer behavior. B2B businesses with consistent sales throughout the year may also choose to analyze their CACs quarterly to better evaluate the impact of new marketing or sales initiatives.

In addition to calculating your overall CAC, you may also calculate CACs on a channel by channel basis. This allows you to better compare the performance of disparate marketing channels against each other.

This report focuses on B2B CACs. For B2C CAC benchmarks, see our report Average Customer Acquisition Cost (CAC) by Industry: B2C Edition

Once you’ve calculated your CACs, you can then compare them to the below industry benchmarks.

Average Customer Acquisition Cost (CAC) By Industry

The table below shares the average CACs in 29 B2B industries. The limitations of our dataset are as follows:

  • Within each industry, we share two types of CAC: Organic and Inorganic. Organic CACs consist primarily of SEO and Organic Social. Inorganic CACs comprise primarily PPC / SEM and Paid Social.
  • The below analysis does not include CACs for email marketing, in-person events, direct mail, outdoor advertising or other forms of lead generation due to insufficient data.
  • All data comes from client analytics accounts, sourced anonymously. Note that our data on Organic CAC is weighted more heavily towards SEO because we are an SEO company; and our data on Inorganic CAC is weighted more heavily towards PPC / SEM than Paid Social, as our clients are primarily B2B. Likewise, the combined Average CAC is weighted 75% organic and 25% inorganic, reflecting our firm’s marketing services.

How Your CAC Relates to Customer Lifetime Value

Where your CAC tells you how much it costs to acquire a new customer, a customer’s lifetime value (LTV) does the opposite: it tells you how much profit, on average, each new customer provides. The simplest way to do so is to divide your monthly or annual profit by the number of unique customers you saw in that time period. You can then multiply that result by the number of years the average customer continues to buy from you to find your average customer LTV.

You should aim for an LTV of at least 3 times your CAC. This provides a comfortable buffer on each side, ensuring that you aren’t overspending on marketing. You should also weigh this ratio against historical trends, and when possible, direct competitor data to provide context. If, for instance, your LTV to CAC ratio is only 2:1 but there’s strong growth compared to historic trends, that doesn’t mean you should cut your marketing spend to try to reduce your CAC. In that case, your LTV will continue to rise as newer customers return and keep making purchases.

This is especially useful to keep in mind if you’ve just launched a new marketing campaign or committed to a longer term strategy. Let’s say you’ve just started an SEO campaign. It will take about 4–6 months before you begin seeing results, meaning that your LTV to CAC ratio will take a hit for those first few months. Once the campaign is well underway, however, your ratio will begin to increase and should continue to do so for the length of your campaign.

How to Lower Your CACs

You may have noticed that organic CAC beats out inorganic CAC in almost every case. This is for two reasons. The first is that an investment in organic channels will take longer to pay off, but results in sustainable lead generation that doesn’t require a constant influx of cash to maintain. The second reason is that your organic CAC relies more on skill and creativity. You need to find a good firm to work with, but if you do, your CAC will be much lower than your competitors who rely on inorganic channels.
