Maintenance ROI & Payback Calculator

Maintenance ROI & Payback Calculator takes the up-front cost, the annual recurring cost, the annual saving you are prepared to state, the basis for that saving in your own words, and your discount rate and returns simple payback in years, return on investment, net present value, and whether the initiative clears the hurdle you set. Net annual benefit = your stated saving − the recurring cost. Simple payback = up-front cost ÷ net annual benefit, and it reads NEVER PAYS BACK rather than returning a negative number when the benefit is not positive. ROI = total net benefit over your horizon ÷ up-front cost. NPV discounts the same cash flows at your own rate. Every one of those turns on the saving YOU stated. Nothing is pre-filled with an outside figure — no assumed saving, no efficiency gain, no downtime reduction percentage, no hurdle rate, no discount rate. Every value on every sheet is one you entered or one computed from what you entered, against the As-of date you set on 1. Setup, never today's date.
