Understanding revenue attributed to marketing

It’s easy to feel like marketing costs are out of control, especially when you cannot directly link revenue to your efforts.

If you would like help calculating your MROI (or to some, ROMI), please click here to email to Cyndie Shaffstall and she will walk you through this exercise step by step.

  1. Think back to your last campaign and in the first row, enter the number of people in your contact list that received your campaign. After assessing your campaign, you might want to see the impact that you could have on your MROI if you were to add more names, for instance, but we’ll get to that later.
  2. The leads row is how many peopled engaged with the campaign. This might be the number of people who completed a form, downloaded a document, tried the demo, or perhaps, just opened an email or phoned you.
  3. The percentage of leads compared to prospects is the prospects-to-leads conversion rate.
  4. Now, give careful consideration to those that became leads. How many of them truly fall within your target audience? In other words, how many are qualified leads? Your company’s criteria for what constitutes a qualified lead might be very strict or very vague. If you became more strict about what is considered qualified, this number should go down. Less strict, and the number should go up.
  5. The resulting percentage is the leads-to-qualified-leads conversion rate.
  6. Now, for a closer examination of the individual qualified leads, you need to speak with the sales team. Have them help you distill how many of the qualified leads they deemed as real opportunities and enter that number.
  7. In this row we can now calculate the qualified-leads-to-opportunities conversion rate.
  8. Now wrapping up the assessment, how many people from your campaign actually became a customer?
  9. In this row, we calculate the opportunity close rate.
  10. To assess the revenue, you must now enter the average amount customers spend and how much you spent on creating the campaign. The rest is pure magic.

Projections and goals

You can also use this calculator to make projections or set goals.

Perhaps you would like to understand the impact of creating a more targeted campaign or higher-value download. In this case, the cost of your campaign will go up, but so should your leads (engagement) rate. If that trickles down through the formula, your ROI will improve. With that knowledge, you could set a goal of doubling the number of people who engage and have Spider Trainers create a fabulous campaign designed to do just that.
