What is Marketing ROI?
Marketing ROI measures the effectiveness of a marketing campaign by calculating the revenue generated as a result of the investment. A higher ROI indicates a successful campaign, while a low or negative ROI can signal the need for adjustments. It's crucial to understand the different approaches to measure ROI, as some are more simplistic, while others are more complex but provide a clearer picture.
How to Calculate Simple ROI of a Marketing Campaign
The simplest method to measure ROI is by calculating the net increase in sales directly attributable to the campaign and dividing it by the cost of the campaign.
Formula:
(Sales Growth - Marketing Cost) / Marketing Cost = ROI
Example:
A company invests $800 in a marketing campaign. This campaign results in a sales increase of $5,000.
ROI Calculation: (($5,000 - $800) / $800) = 525%
Interpretation: For every dollar spent on the marketing campaign, the company generated $5.25 in sales revenue, indicating a highly successful campaign.
Campaign Attributable ROI of a Marketing Campaign
To get a more precise ROI, it's important to factor in organic growth that was already happening before the campaign. This helps to isolate the impact of the marketing campaign from the natural growth of sales.
Formula:
(Sales Growth - Average Organic Growth - Marketing Cost) / Marketing Cost = ROI
Example:
A business experiences organic growth of 5% per month. A new marketing campaign is launched at a cost of $35,000, leading to a total sales increase of $60,000 for the month.
Organic growth: $60,000 * 5% = $3,000
Net sales growth (attributed to the campaign): $60,000 - $3,000 = $57,000
ROI Calculation:
($57,000 - $35,000) / $35,000 = 63%
Challenges in Measuring Marketing Campaign ROI
While calculating ROI is essential, several challenges may arise:
Timeframe: Marketing campaigns often take time to show results. Early calculations might not reflect the full impact of a campaign.
Indirect Benefits: Many campaigns aim to increase brand awareness, loyalty, or engagement, rather than direct sales. These metrics can be harder to quantify in dollar terms.
Multiple Touchpoints: Marketing is rarely a single-action process. Customers often interact with multiple channels before making a purchase, making it difficult to attribute sales to one specific marketing effort.
Alternative Methods to Measure ROI
Sales growth isn’t the only way to measure ROI. Some campaigns focus on generating leads, building brand awareness, or fostering engagement. In such cases, alternative methods are needed:
Lead Generation Campaigns: Calculate ROI by multiplying the number of leads generated by the conversion rate and average customer value.
Non-Sales Conversions: For campaigns that focus on gathering sign-ups or email leads, ROI can be measured by the conversion of those leads into paying customers over time.
What is a Good ROI?
The definition of a "good" ROI varies across industries. However, in general, an ROI of 5:1 is considered strong. This means that for every dollar spent on marketing, the business earns five dollars in revenue. An ROI of 10:1 is exceptional, while anything less than 2:1 may indicate that the campaign is underperforming.
Key Performance Indicators (KPIs)

Beyond sales, there are other metrics that businesses use to measure the effectiveness of marketing campaigns:
Leads Generated
Customer Acquisition Cost (CAC)
Customer Lifetime Value (CLV)
Social Media Engagement
Click-through Rates (CTR)
Search Engine Rankings
Brand Awareness
While these KPIs might not directly impact revenue, they provide insight into how well a campaign is performing in driving long-term growth.
Marketing campaigns are an investment, and to ensure they are successful, it’s essential to measure their ROI. Whether you use simple calculations or more complex methods that account for organic growth, knowing the return on investment helps businesses refine their strategies, allocate budgets effectively, and ensure long-term success. As you measure ROI, keep in mind the importance of time, indirect benefits, and campaign goals beyond just sales.
