How to Calculate Email Marketing ROI
Return on Investment (ROI) is the definitive metric for evaluating the success of your email marketing campaigns. It tells you exactly how much revenue you generate for every dollar spent. This calculator uses the standard formula:
ROI = ((Total Revenue – Campaign Cost) / Campaign Cost) * 100
To get an accurate result, you need to input your funnel metrics step-by-step. Start with your total audience size, then apply your engagement rates (Open Rate and Click-Through Rate) to estimate traffic. Finally, your Conversion Rate and Average Order Value determine the total revenue generated.
Understanding Your Metrics
- Open Rate: The percentage of recipients who open your email. A healthy benchmark varies by industry but often sits between 17-28%.
- Click-Through Rate (CTR): The percentage of openers who clicked a link. This measures the effectiveness of your email copy and call-to-action (CTA).
- Conversion Rate: The percentage of people who clicked through and completed a purchase. This relies heavily on your landing page quality.
- Average Order Value (AOV): The average dollar amount spent each time a customer places an order via your campaign.
Improving Your Email ROI
If your calculator results show a negative or low ROI, consider A/B testing your subject lines to improve Open Rates, optimizing your email design for mobile to boost CTR, or refining your landing page offer to increase conversions. Even small fractional improvements in conversion rates can lead to significant jumps in total revenue and profit.
