What are cost metrics in marketing (and which ones should you track)?

If you're aiming to make the most of your marketing budget, optimize your spending, or simply understand where your money is going, you'll want to look at marketing cost metrics. But what exactly are marketing cost metrics, and which ones should you be tracking?

In this post, we dive deep into the realm of marketing cost metrics, breaking down what they are, why they're essential for your marketing strategy, and which cost metrics are the most important. Plus, we'll guide you through the process of calculating these metrics yourself, so you can start making informed, data-driven decisions that enhance your marketing efficiency and ROI.

What are marketing cost metrics?

Cost metrics in marketing are vital indicators for gauging the efficiency and financial viability of your marketing strategies. Simply put, marketing cost metrics show how much money is being spent to achieve specific marketing goals.

Generally they take the form of ‘Cost per X’ such as cost per lead (CPL), cost per click (CPC), or cost per impression (CPM). These metrics provide insights into the financial expenditure associated with your campaigns and help determine the return on investment (ROI) for various marketing activities. By analyzing cost metrics, businesses can understand the monetary impact of their marketing efforts and make informed decisions on where to allocate their budgets for maximum effectiveness.

What cost metrics should marketers be tracking?

So, that’s what cost metrics are, but what are the key cost metrics marketers should be tracking?

Cost Per Lead (CPL)

Cost Per Lead (CPL) measures how much money a business spends to generate a single lead. This includes all expenses related to marketing efforts such as advertising, promotions, and any other resources spent on attracting potential customers. A lead can be anyone who has expressed interest in your product or service, such as someone who signs up for a newsletter or requests a demo.

To calculate CPL, divide the total marketing costs by the number of leads generated during a specific period.

Here’s the formula:

CPL = Total Marketing Expenses / Number of Leads Generated

Understanding your CPL will help you to understand how efficiently you are spending money to attract potential customers.

Cost Per Click (CPC)

Cost Per Click (CPC) measures the amount a business pays each time a potential customer clicks on an online advertisement. This includes all costs related to digital advertising efforts such as pay-per-click campaigns on search engines and social media platforms. Each click signifies that someone has interacted with your ad, indicating interest in your product or service.

To determine CPC, divide the cost of an advertising campaign over a specific period by the number of clicks it received during that time.

Here’s the formula:

CPC = Total Advertising Cost / Number of Clicks

Knowing your CPC helps you assess the cost-effectiveness of your online ads and optimize your advertising budget.

Cost Per Impression (CPM)

Cost Per Impression (CPM) measures the cost a business incurs for every thousand impressions of an online advertisement (the M stands for ‘mille’). This metric includes all your costs related to displaying ads on various digital platforms, such as websites and social media.

To calculate CPM, divide the total cost of the advertising campaign by the number of impressions (in thousands) it received during a specific timeframe.

Here’s the formula:

CPM = (Total Advertising Cost / Number of Impressions) x 1,000

Because an impression occurs each time an ad is shown to a user, regardless of whether they interact with it, CPM can be a good way to measure the efficiency of brand awareness or reach campaigns.

Customer Acquisition Cost (CAC)

Customer Acquisition Cost (CAC) or Cost Per Acquisition (CPA) measures how much money a business spends to gain a new customer. This includes all expenses related to marketing and sales efforts such as advertising, salaries, commissions, and any other resources spent on acquiring customers. To be profitable, the cost of acquiring a customer needs to be less than the amount of income generated by that customer, or the customer lifetime value (CLV).

To calculate CAC, divide the total marketing and sales costs by the number of new customers acquired during a specific period.  

Here’s the formula:

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

Understanding your CAC will help you to understand how efficiently you are spending money to get new customers and therefore make better budget decisions.

Marketing Percentage of Customer Acquisition Cost (M%-CAC)

Marketing Percentage of Customer Acquisition Cost (M%-CAC) measures specifically the proportion of customer acquisition costs that are attributed to marketing efforts. This naturally only includes marketing-related expenses, such as advertising, promotions, and content creation,as part of the overall cost of acquiring new customers, but not other costs such as sales team’s salaries and commissions or customer support costs.

M%-CAC is given as a percentage with a high M%-CAC indicating a heavy reliance on marketing. This could be either an indication of strong marketing effectiveness or a need for better balance in customer acquisition strategies. A low M%-CAC indicates more diversified or efficient customer acquisition strategies, but it might also point to an opportunity for increased marketing investment to boost growth.

To calculate M%-CAC, divide the total marketing expenses by the total customer acquisition cost, and multiply by 100 to get a percentage.

Here’s the formula:

M%-CAC = (Marketing Expenses / Total CAC) x 100

Understanding your M%-CAC helps you evaluate the effectiveness of your marketing spend within the broader context of customer acquisition, ensuring that your investment in marketing is proportionate and contributes effectively to acquiring new customers.

Customer Lifetime Value (CLTV)

Customer Lifetime Value (CLTV) measures the total revenue a business can expect to earn from a customer over the entire duration of their relationship. This includes all purchases and interactions that contribute to the customer's value, such as repeat sales, subscriptions, and any additional services they might use. CLTV provides insights into the long-term profitability of acquiring and retaining customers and should always be compared with the CAC because, if the cost of acquiring a customer is more than the amount of revenue that that customer will generate, you are ultimately losing money.

To calculate CLTV, multiply the average purchase value by the number of purchases per year, and then multiply by the average customer lifespan in years.

Here’s the formula:

CLTV = Average Purchase Value x Number of Purchases per Year x Average Customer Lifespan

Understanding your CLTV helps you make informed decisions about customer acquisition and retention strategies, ensuring that you invest appropriately in marketing efforts that foster long-term customer relationships and maximize profitability.

Customer Retention Cost (CRC)

Customer Retention Cost (CRC) measures the expenses incurred to retain existing customers and keep them engaged with your brand. This metric includes costs related to loyalty programs, customer support, engagement initiatives, and any other activities aimed at maintaining customer satisfaction and reducing churn.

CRC provides insights into how much a business is spending to ensure customers continue using their products or services For example, a high CRC emphasizes a significant focus on retaining customers, which could be beneficial but also might require cost assessments. A low CRC indicates efficient retention strategies but may suggest the need for increased investment to further enhance customer loyalty and reduce churn.

To calculate CRC, divide the total retention costs by the number of retained customers during a specific period.

Here’s the formula:

CRC = Total Retention Costs / Number of Retained Customers

Overall, understanding your CRC helps you evaluate the efficiency of your retention strategies, ensuring that your investments in customer retention are justified and contributing effectively to maintaining a loyal customer base.

Return on Investment (ROI)

Last, but not least, Return on Investment (ROI) measures the overall profitability of a marketing campaign by comparing the revenue generated to the costs incurred. It includes all the costs related to the campaign, such as advertising, production, and distribution costs. To calculate ROI, subtract the total costs from the total revenue, then divide by the total costs, and multiply by 100 to get a percentage.

ROI is given as a percentage and indicates how effectively your marketing investments are translating into profits - the higher the percentage the more returns you are making from your investment. A positive ROI means a campaign is generating more income than it costs. For example, 100% ROI means your campaign has doubled the amount of money you invested in it, 50% is 1.5 times the amount invested, and so on. Conversely, a negative ROI means your campaigns are costing more money than they are generating.

Here’s the formula:

ROI = ((Total Revenue - Total Costs) / Total Costs) x 100

Ultimately, understanding your ROI helps you determine the financial success of your marketing efforts, allowing you to assess which campaigns are the most profitable and which you may want to stop.

Maximizing the Value of Marketing Cost Metrics

Cost metrics are key to figuring out how wisely you're spending your marketing budget. They show you how efficiently you're acquiring and keeping customers, which is crucial for getting the best bang for your buck. But, if you only look at cost metrics, you might miss the bigger picture of how your marketing is really doing.

To get the most out of your marketing cost metrics, you should mix them with other data sources. This means looking at cost metrics alongside conversion data, customer behavior, web analytics, social media insights, email stats, and even offline data. Doing this gives you a fuller picture of how your marketing efforts are performing.

Remember, while cost metrics tell you how much you're spending, other metrics show how well your campaigns are connecting with people. Conversion rates, engagement rates, and customer satisfaction scores can help you see where your marketing is working and where it might need some tweaks. By combining these different types of data, you can get a more complete view of your marketing performance, make better decisions, and fine-tune your strategies for better results.
