Cloud, plant-hosted or hybrid MES?
Compare cloud, plant-hosted and hybrid MES by execution dependencies, outage behavior, operating responsibility and the evidence to request.
MES ownership cost
Combine implementation, internal effort, annual operation and exit costs over your planning horizon.
Build a consistent boundary
Enter scoped supplier implementation and integration costs, then add internal project hours at a loaded hourly rate. Include software, support, hosting, backup testing and recurring interface maintenance in the annual amount. The exit field represents a one-time allowance at the end of the planning horizon. Avoid counting the same work in both supplier fees and internal hours.
Formula and illustrative example
Upfront = implementation + internal hours × hourly cost. Total ownership cost = upfront + annual operating cost × years + exit cost. With the illustrative defaults, $80,000 + 600 × $60 = $116,000 upfront. Five years of $30,000 annual costs and a $10,000 exit allowance produce $276,000 total, or $55,200 per year. These are invented planning inputs, not vendor prices.
Limits
The model uses constant annual costs and no discounting, inflation, tax, financing or depreciation. Use a spreadsheet for phased deployments, changing subscription tiers or cash-flow timing. Document exclusions and compare alternatives using the same horizon. Zero years is invalid; negative or missing inputs must be corrected.
