How this calculator works

Return on investment compares the net gain of an initiative against what it cost. We compute both ROI percent and the payback period implied by your monthly return.

Formula transparency
ROI = (Gain − Cost) / Cost

ROI % = (Net gain − Cost) / Cost × 100. Payback (months) = Cost / Monthly net gain.
