CAC is of growing importance to both companies and investors.
It is a poor business decision if you fail to consider your CAC when planning your go-to-market strategy, or when you decide to scale up a particular marketing channel (e.g. Facebook ads).
Understanding what your CAC is helps you understand the potential profitability of your marketing and sales activities, and the scalability of your venture.
Put simply, CAC is the total cost of acquiring your total customers, divided by the total number of customers you have.
If you acquire customers mainly through digital ads, analysing your CAC will allow you to understand which sales or marketing process(es) you need to optimise.
Take note that a high CAC does not mean your business is naturally unprofitable. To understand whether your CAC is justified, you need to compare it against your customer lifetime value (CLTV).
An optimal LTV ratio is naturally much higher than 1.0, as it suggests the value a customer brings to your company far exceeds the cost of acquiring a customer.
To put this into perspective, assume that you are a D2C e-commerce subscription startup, and your CAC is £50.00 while your monthly subscription is only £30.00
At first glance, this might look as if that your company is unprofitable.
However, if an average customer stays subscribed for 5 months, your CLTV is actually £150.00, which suggests a LTV/CAC ratio of 3.0x. This means that you can usually justify a high CAC if your LTV is high, either by increasing your average order value, or the length of your customer relationships.
Segmenting your CAC across different marketing channels allow you to understand which channel is more profitable for you.
These marketing channels include:
- Google AdWords
- Facebook and Instagram Ads
- Display Ads (such as Google Display Network)
- Affiliate Advertising
- New advertising platforms, such as TikTok
- Unpaid marketing channels, such as blogs (content marketing) and search engine optimisation (SEO)
To calculate the channel-specific CAC, simply divide the marketing budget spent on that channel, divided by the number of customers (conversions) attributed to that specific channel.
Once you have figured out each channel's CAC, you can rank and prioritize your marketing channels and decide which channel deserves a greater allocation of your marketing budget.
On channels such as Google Ads, you might be limited in scale, as your reach is typically constrained by the keyword volumes related to your offering.
Platforms such as Facebook, however, provide technically near-infinite reach, as you target customers based on different demographic factors. The possibilities are almost endless.
