MES ROI: separate cash benefits from saved time
Build an MES return case from realized benefits after recurring costs. Avoid double counting and test a transparent illustrative payback example.
MES simple payback
Test the business case using annual net benefits after recurring operating costs.
Enter cash benefits, not dashboard improvements
Use annual net cash benefit after recurring software, support and operating costs. Include only improvements the plant can reasonably monetize. Saved operator minutes are not automatically payroll savings. Avoid counting the same production gain as both extra sales and avoided overtime. The upfront cost should include implementation, integration, internal effort and training.
Formula and illustrative example
Simple payback = upfront cost ÷ annual net cash benefit. Undiscounted net benefit over the selected horizon = annual net benefit × years − upfront cost. With illustrative inputs of $120,000 and $40,000 a year, payback is three years and five-year net benefit is $80,000. These values are not a claim about supplier performance or typical returns.
Limits and downside case
This tool assumes a constant annual benefit starting immediately and does not include ramp-up, discounting, tax or financing. A zero annual benefit has no finite payback unless the upfront investment is also zero. Recalculate with delayed adoption and lower benefits. For actual capital approval use a dated cash-flow model agreed with finance, and keep the source for every assumption.
