How to Use the Email Marketing ROI Calculator

Return on Investment (ROI) is the most critical metric for evaluating your email marketing strategy. This calculator helps you determine if your email spend—including software costs, design, and copywriting—is generating a positive return.

Understanding the Inputs:

  • Campaign Cost: Include the total cost of your email platform, labor hours, and any third-party tools or images used.
  • Open Rate: The percentage of recipients who opened your email.
  • Click-to-Open Rate (CTOR): The percentage of openers who clicked a link.
  • Conversion Rate: The percentage of clickers who completed the desired action (e.g., made a purchase).
  • Average Order Value: The average dollar amount spent by a customer per transaction.

The ROI Formula

ROI = ((Revenue – Cost) / Cost) x 100

Example Calculation:

If you spend $200 to send a campaign to 5,000 subscribers, and 100 people buy a $50 product (Total Revenue = $5,000):

$5,000 Revenue – $200 Cost = $4,800 Profit. ($4,800 / $200) * 100 = 2,400% ROI.
