TL;DR
Why does CAC Matter? Rising ad costs and tighter marketing budgets mean your CAC impacts profitability directly. (For example, Google Ads’ cost per lead grew 5% in just one year.)
What is CAC? CAC measures how much it costs your business to acquire a single paying customer. It’s crucial for understanding profitability, ROI, and your payback period.
How do I calculate CAC? CAC = (Total sales and marketing cost) / Total number of new customers.
What’s a Good CAC? Varies by industry and business model but should align with your customer lifetime value (LTV). Aim for an LTV:CAC ratio of 3:1 or better for sustainable growth. Benchmark against industry averages to gauge competitiveness.
Key Factors Influencing CAC:
- Marketing channel effectiveness and budget allocation
- Length of your sales cycle (longer cycles usually increase CAC)
- Lead quality (cold leads raise costs, warm leads lower them)
- Conversion rates through your funnel stages
- Customer retention and referral rates (higher retention reduces CAC)
Strategies to Reduce and Improve CAC:
- Increase website conversions through optimised copy, CTAs, SEO, and speed
- Enhance product value—add features, upgrades, and improve customer experience
- Use a Customer Relationship Management (CRM) system to personalise marketing and streamline sales (e.g., Act! offers a comprehensive CRM with automation and AI tools)
- Regularly review and adjust your customer acquisition strategies based on performance data and A/B testing
Every new customer your business gets contributes to its revenue. But there’s a cost associated with acquiring that customer. That customer acquisition cost, or CAC, plays a crucial role in determining your profitability and long-term business viability.
But why does CAC matter more than ever now?
Well, rising ad costs, shrinking marketing budgets, and the pressure to increase marketing return on investment (ROI) all contribute to it. Case in point—the cost per lead via Google Ads has increased by 5 percent in one year alone.
That makes it necessary to understand where you stand in terms of your CAC and how you can minimise it using tools like CRMs. The reason? A lower CAC reduces your expenses and increases the chances of sustained profitability.
Let’s dive in.
What is customer acquisition cost (CAC)?
Simply put, CAC is a business metric that tells you the cost your business incurs to acquire an average customer. It’s an important metric that helps you determine your profitability, payback period, and marketing ROI. You’ll also know if your ad spend, sales and marketing campaigns are cost-effective and bringing in the necessary results (or not).
CAC works closely with customer lifetime value (LTV or CLV), which is the total revenue generated by the average customer across their lifetime with your business. CLV must be much higher than CAC to build a profitable business, with the ideal LTV:CAC ratio being 3:1.
Additionally, CAC, along with gross profit per customer, helps you find your payback period. This is the time it takes your business to generate enough profit to make up for the CAC. However, this is an advanced concept and requires detailed calculations.
Finally, your CAC gives you a clearer idea of your ROI. If you have a low CAC and are generating high revenue, you get a better ROI. It justifies your sales and marketing spend.
How to calculate customer acquisition cost
The formula to calculate CAC is fairly straightforward. Simply divide your total marketing and sales costs by the number of new customers acquired.
CAC = (Total sales and marketing cost) / Total number of new customers
For instance, if your total marketing and sales cost is $10,000 and you acquired 200 paying customers, your CAC would be $50.
CAC = $10,000/200 = $50
To ensure that you get an accurate figure, be sure to include these costs:
- Marketing and sales spend
- Software subscription amounts
- Personnel salaries
- Administrative costs
- Content creation expenses
- Discounting/promotion costs
There’s one more critical aspect that determines your CAC calculation: time. You need to calculate your CAC for different timeframes, as they will affect both variables involved in the calculation—costs and acquired customers.
Typically, CAC is calculated monthly, quarterly, annually, or per campaign. This way, you get a holistic view of your costs and ROI.
What’s a good CAC?
So, you’ve calculated your CAC. You have a number. But is it good? It’s only natural to have this question in mind.
Well, here’s the thing—the definition of a “good” CAC differs for each industry. And even within the same industry, your pricing model and retention shape the ideal number.
The best way of getting to the accurate figure is to weigh it alongside your LTV. Generally, your LTV:CAC ratio for a particular time period must be 3:1 or higher to be considered healthy.
You can calculate your LTV by using this formula:
LTV = Average purchase amount x Frequency x Customer lifespan
For example, if your average customer purchases goods worth $50 twice each month and sticks with your business for 12 months, your customer lifetime value would be $1.200
So, for the example above, a good CAC would be lower than $400.
Another way of benchmarking your CAC is to check it against the industry average. For instance, the average CAC of the B2B SaaS industry is $239, while the same for real estate is $791. If your CAC is lower than the industry average, you’re likely doing well.
Factors that influence CAC
Your product, its pricing, the marketing channels you use, and several other factors influence your CAC. Let’s take a look at these in detail.
Marketing efficiency and channel mix
Every marketing channel carries different costs. Promoting with competitive keywords or renting large billboards could be expensive, while micro-influencers can be cheaper.
How effectively you use your marketing budget can make a big difference to your CAC. If you use your budget wisely and adopt data-driven sales or marketing tactics, you could end up reducing your CAC.
Sales cycle length
Every product or service has a different sales cycle. Typically, the sales cycles are short for B2C products or services as they involve a single decision maker. This isn’t the case in B2B purchases, where multiple stakeholders are involved.
Additionally, enterprise software or costlier products often have long-winded sales cycles due to their price tags. Protracted sales cycles mean higher CAC as your marketing and sales efforts need to go on for a long time to drive a conversion.

Lead quality
If your lead is warm and ready to make a purchase, they might just need a nudge to buy from you. On the other hand, a cold lead would require more marketing and sales efforts, leading to higher CAC.
Conversion rates at each funnel stage
You may have thousands of prospects entering your acquisition funnel, but if your conversion rate at each stage is low, you’ll end up with fewer paying customers. Higher conversion rates, on the contrary, help you gain more customers for the same amount of effort and cost, resulting in a lower CAC.
Customer retention and referral behaviour
When you retain a greater chunk of your existing customers, LTV increases. Also, your CAC drops as you don’t have to continuously pump money into marketing to generate revenue. Similarly, referrals can lower your marketing costs and drive your LTV higher.
How to reduce and improve CAC
Reducing your CAC is necessary if you want to see sustained growth and profitability. If you focus first on the factors listed above, you’ll likely see a dip in your CAC.
Beyond those factors, try the following to see your CAC improve even further.
Increase website conversions
A high-performing website helps you get inbound leads and sales. Write compelling web and landing page copy and place calls-to-action (CTAs) at the right spots. Make the website responsive, optimise for SEO, and work on the page loading speed.
Raise customer value
Make your product conceptually more valuable to your customers by adding enhancements or features customers have requested. Offering a new product or adding upgrade options is another approach, along with elevating your overall customer experience.
These enhancements may carry minimal development costs but increase average order size. This approach simultaneously improves customer acquisition and retention and drives referrals, ultimately leading to a higher LTV.
Implement customer relationship management (CRM)
CRMs help you manage your customer interactions from a single spot, enabling you to quickly spot and resolve any issues prospects face. The access to customer data also means that you can better personalise your marketing and work on retaining customers.
The result? Lower CAC and higher LTV.
And when you choose Act!, you get more than just a CRM. It comes with the complete feature set, from sales pipeline management to email marketing automation. This helps your small business hit sales goals while keeping costs low.

Frequently asked questions
Cost Per Acquisition (CPA) refers to the expenses your business incurs to acquire a specific action like form submission or app install. It's typically used to measure the success of individual campaigns. On the other hand, CAC deals with the total cost of acquiring a paying customer, making it a broader metric than CPA.
A customer goes through awareness, consideration, conversion, and retention in the customer acquisition funnel. When you're calculating your CAC, you need to sum up all the costs in the first three stages. The cost of retention should be measured separately.
COGS, or Cost of Goods Sold, is the total cost you incur for producing or delivering the goods or services you're selling. It primarily includes the production costs. CAC represents the cost of acquiring a new customer and deals with marketing and sales efficiency.
