How to use the ROI Calculator
ROI = (Amount returned − Amount invested) ÷ Amount invested × 100. Annualised ROI spreads the return over the number of years so you can compare investments of different lengths.
For marketing, count only the profit from extra sales, not total revenue, to avoid overstating ROI.
