How this calculator works
The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
Attributed contribution
Use attributed email revenue and subtract the direct product cost attached to that revenue. MarginKoala does not assume open rate, click rate, conversion rate or margin when the user already has attributed sales.
Program-cost ROI
Subtract the email campaign or program costs entered and compare the remaining contribution with that cost. A zero program cost can still show contribution dollars, but ROI is undefined because there is no positive denominator.
