Calculating Your Marketing Efficiency Ratio (MER)

A Free Guide and Calculator

Marketing Efficiency Ratio (MER) is a straightforward yet powerful metric that gives you a high-level view of how effectively your marketing budget is driving revenue. By comparing your total revenue to your total marketing spend, MER allows you to assess the combined impact of all your marketing efforts, regardless of the channel.

Unlike more granular metrics like ROAS (Return on Ad Spend), which evaluates the performance of individual campaigns, MER provides an overarching perspective that helps you understand how well your overall marketing strategy is working.

What is Marketing Efficiency Ratio (MER)

Marketing Efficiency Ratio (MER) is a high-level metric that evaluates the overall effectiveness of your marketing spend by comparing total revenue to total marketing costs. MER provides a holistic view of your marketing performance across all channels.

Let’s say your business generated £500,000 in total revenue last month, and your total marketing spend was £50,000. Using the formula:

Why is MER Important?

MER is an essential tool for marketers because it helps you:

• Evaluate Overall Marketing Performance: It consolidates the impact of all marketing activities into a single, easy-to-understand ratio.
• Benchmark Progress Over Time: Track improvements in efficiency and determine whether your marketing efforts are becoming more effective.
• Optimise Marketing Budgets: Identify if your overall marketing spend is generating a strong return and adjust budgets accordingly.
• Simplify Reporting: Provide stakeholders with a clear and concise measure of marketing success.

Why Use MER Alongside Other Metrics?

While MER is a valuable metric, it works best when used in conjunction with others like ROAS (Return on Ad Spend) and CAC (Customer Acquisition Cost). Together, these metrics provide a more comprehensive view of your marketing effectiveness.

For example:

• High MER but Low ROAS: Indicates that while overall marketing is efficient, specific channels or campaigns might be underperforming.
• High MER but High CAC: Suggests that while your marketing is generating revenue, customer acquisition might be too costly.

We hope that our free MER Calculator helped you to determine if your marketing is delivering sufficient value and where you might need to adjust your strategies.

By tracking this key metric, you’ll be better equipped to allocate budgets, improve campaigns, and ultimately drive greater business success.
