Let's use the simplest MROI formula, and see how you did. MROI = total profit/marketing costs. You made $1,200 profit ($30 per widget x 40 customers) from this marketing campaign. It cost you $900 in marketing expenses ($300 design, $300 printing, $300 mailing).

Your MROI for this camping is 133% (or 1,200/900). Not only did your marketing pay for itself, it returned 33% more, expanded your market, raised awareness, and generated profits. So, the next time someone tells you that marketing is an expense to the organization, defend your efforts with MROI and demonstrate the real value of marketing.
