ROI of Sales Funnel: Calculating, Importance, and Tips to Improve Success

ROI of Sales Funnel


In the world of marketing, the return on investment (ROI) is a key metric that businesses use to evaluate the success of their marketing campaigns. It measures the profit earned from every dollar spent on marketing efforts and helps to determine whether those efforts are generating enough leads and sales. In this article, we will explore what marketing ROI is, how to calculate it, and why it is important for businesses to understand and optimize their ROI.

What is Marketing ROI?

Marketing ROI refers to the profit earned from every dollar a business spends on marketing efforts. It is used to quantify and justify how marketing programs and campaigns generate revenue for the business. ROI is calculated by dividing the sales growth (revenue) generated by marketing efforts by the total cost of those marketing activities. A positive ROI indicates that the business is making more money than it is investing, while a negative ROI means that the marketing expenses exceed the earnings.

The Importance of Calculating Marketing ROI

Calculating marketing ROI is crucial for businesses for several reasons. Firstly, it helps marketers justify their marketing expenses and allocate resources and budgets for future campaigns. By accurately calculating ROI, marketers can determine which campaigns are driving conversions and allocate budgets accordingly. Additionally, measuring ROI helps gauge the success of marketing efforts and allows marketers to make adjustments to maximize impact. It also helps businesses identify which marketing channels are generating the most revenue and make informed decisions about where to allocate their marketing budget. Finally, comparing marketing ROI with competitors can provide businesses with insights into how they perform within their industry and make better strategic decisions.

How to Calculate Marketing ROI

To calculate marketing ROI, you need to subtract the cost of the marketing campaign from the sales revenue generated and divide it by the cost of the campaign. The formula for calculating ROI is as follows:

ROI = (Sales Revenue – Marketing Cost) / Marketing Cost

It is important to note that this formula assumes that all sales growth is linked to marketing efforts. However, in reality, there are often external factors that can impact campaign success, such as weather, events, or supply chain issues. To generate a more realistic view of marketing impact and ROI, businesses should account for these external factors.

What is a Good Marketing ROI?

A good marketing ROI is subjective and depends on various factors such as the industry, niche, and use case of the business. Generally, a marketing ROI of 3:1 or higher is considered exceptional, as it indicates that the business is turning a profit even after accounting for external variables. A ratio below 1:1 means that the marketing expenses exceed the revenue generated, indicating that the campaign is not profitable. However, it is important to consider other metrics and business goals alongside ROI, as ROI is not the only measure of marketing success.

Challenges in Measuring Marketing ROI

Measuring marketing ROI is not without its challenges. Firstly, marketers need to establish a clear and consistent sales baseline to measure against. They also need to account for external factors that may impact campaign success, such as events or supply chain issues. Furthermore, campaigns often use multiple online and offline channels simultaneously. Focusing ROI measurements on a single channel will only provide a limited view of the overall marketing impact. Finally, it takes multiple touchpoints before a potential customer makes a buying decision. Marketers need to understand the relationship between these touchpoints in the sales funnel and use a multi-touch attribution model to accurately measure ROI.

Tips to Improve Marketing ROI

To improve marketing ROI, businesses can take several steps. Firstly, they should set clear goals for every marketing channel and consider the various touchpoints and interactions between channels. Next, they should review all costs associated with marketing campaigns, including salaries, overhead costs, and development time for new channels. It may take several months for new marketing channels to reach optimal efficiency, so businesses should allow sufficient time before evaluating their ROI. Additionally, businesses should focus on the right metrics and strategies that can unify disparate attributions, both online and offline, to gain clearer insights and more accurate ROI measurement.

Examples of Marketing ROI for Different Channels

Different marketing channels can have varying impacts on ROI. Here are a few examples:

  • Email Marketing: A local cat daycare offers a weekly e-newsletter to customers. A cat food company pays them $100 to place an ad in the newsletter, resulting in 17 purchases. The ROI formula would be: (Revenue from Sales – Cost of Ad)/Cost of Ad = ROI.

  • Content Marketing: A law firm creates five blog posts about tenants’ rights and spends $900 on creation and $100 on promotion. The posts result in four new clients, with an average revenue of $2,000 per client. The ROI formula would be: (Revenue from Clients – Marketing Cost)/Marketing Cost = ROI.

  • Social Media Advertising: A lifestyle publication offers a one-month free trial to boost web subscriptions. They spend $100 on a boosted post that attracts 20 free-trial subscribers, four of whom become paid subscribers. The ROI formula would be: (Revenue from Subscribers – Marketing Cost)/Marketing Cost = ROI.


In conclusion, measuring marketing ROI is essential for businesses to evaluate the success of their marketing campaigns and allocate resources effectively. It helps businesses justify their marketing expenses, gauge their success, and make informed decisions about budget allocation. By understanding how to calculate and optimize marketing ROI, businesses can maximize their return on investment and drive growth.
