When customers come in and engage with your brand, whether they’re purchasing a product or using a service, it’s always exciting. You get the opportunity to help them see real value in what they’re receiving.
Without a doubt, it’s one of the best parts of running a business.
And for most small businesses in Australia (and around the world), that’s always been the end goal, creating value that keeps customers coming back. Unfortunately, most of them aren’t fully aware of how much it costs to acquire a customer.
That’s a silent growth killer right there.
Learn more about why your customer acquisition cost (CAC) matters, how to calculate it, and when it makes sense for your marketing.

What is Customer Acquisition Cost (CAC)?
Customer Acquisition Cost (CAC) measures the total cost a business spends to acquire a new customer. This includes your marketing expenses, your sales efforts, your software tools, and even your overhead costs.
Think of it as a key performance indicator (KPI) within your business that everybody knows quite literally.
It has a vital aspect because it determines your actual profitability, dictates marketing budgets, and proves whether your business can sustainably scale.

CAC Meaning in Marketing, Sales, and Customer Success: An Overview
The acquisition cost per customer spans across marketing, sales, and customer success. Each function contributes to the overall cost of acquiring and retaining a customer. So, it’s a tricky situation to be in if you’re measuring every item in your business.
See what CAC means across different departments below:
CAC Meaning in Marketing
In marketing, CAC refers to the cost of generating leads and attracting potential customers. This includes expenses for paid advertising, content creation, SEO efforts, and campaign strategies.
CAC Meaning in Sales
From a sales perspective, CAC includes the cost of converting leads into paying customers. This can involve salaries, commissions, CRM tools, and the time spent nurturing prospects through the sales funnel.
If your sales cycle is long or inefficient, your CAC will naturally increase. The better qualified leads are, the less time and cost spent on closing deals.
CAC Meaning in Customer Success
While customer success doesn’t directly acquire customers, it makes an impact on Customer Lifetime Value (CLV), which directly affects how sustainable your CAC is. Having strong retention means you can reduce the pressure to constantly acquire new customers.
How to Calculate the Cost of Customer Acquisition (+ CAC Formula)
Before you start calculating the cost of customer acquisition, what you want to do first is to lay out what you will calculate CAC for. Do you need it for a marketing campaign or for your business as a whole?
In practice, you can do it in this order:
- Select a Time Frame
- CAC Calculation
- Compare CAC to Business Metrics
Let's break it down one by one!
Select a Time Frame
Choose a specific time frame for your customer acquisition cost calculation. It can be monthly, quarterly, or annually. This will help narrow down and compare the scope of the data you’ve gathered.
CAC Calculation
Add up all marketing and sales expenses within that time frame. This includes marketing spend, sales expenses, tools, and operational overhead tied to acquisition efforts. Then divide that total by the number of new customers acquired during the same period.
Here is a CAC formula you can use:
CAC = Total Sales and Marketing Costs ÷ Number of New Customers Acquired
While the formula itself is very simple, the accuracy of your CAC depends on how thoroughly you track your costs. So, if you miss one, for example, software subscriptions or personnel costs, it can lead to giving you a false sense of profitability.
Compare CAC to Business Metrics
Your CAC doesn’t mean much on its own. To get real insights, compare it to other business metrics after you have calculated your CAC. This shows whether your acquisition strategy supports long-term financial health or if you’re overspending on bringing customers in.
What Should Be Included in CAC Calculation
There are four categories we will cover that should be included when you calculate your customer acquisition cost.
Here’s a breakdown of each that’s worth checking out:
- Ad Spend: This includes all costs tied to paid digital marketing campaigns such as Google Ads, Meta Ads, and LinkedIn Ads.
- Personnel Costs: The salaries, commissions, and contractor fees for anyone involved in your business operation, including your marketing team, sales reps, and business development staff.
- Software & Tech Stack: Your software and tech stack, like CRM systems, email marketing platforms, automation tools, analytics software, landing page builders, and any subscriptions used to support marketing and sales operations, are a direct cost of acquiring customers.
- Overhead Costs: This typically includes your office space, utilities, administrative support, and a portion of general business expenses.
