Additive MES ROI: How to Calculate Costs, Benefits and Payback
To calculate additive MES ROI, compare the financial benefits attributable to the system with its full implementation and running costs over the same period. Measure your current operation first, distinguish cash savings from released staff time, and calculate payback using the timing of the resulting cash flows.
The calculation starts with familiar production problems: hours spent preparing reports, repeated data entry, avoidable rework or jobs waiting for information. The important step is establishing which of those costs the proposed system can change.
This guide explains how to turn those observations into a business case, with a worked example you can adapt to your own operation.
Start with a production baseline
Choose a defined scope for the investment: the site, processes, users and job types it will cover. Then measure the activities you expect to improve. Use a representative period and include variation in the work rather than selecting only the easiest repeat orders.
Useful starting points include:
Area | What to measure before implementation |
Administration | Staff time spent entering, finding and transferring production information |
Reporting | Time spent assembling job records and correcting missing information |
Scrap and rework | Frequency, causes and the costs that could actually be avoided |
Scheduling | Delays associated with missing information, conflicting plans or unprepared work |
Delivery | Late orders, expediting costs and recurring reasons for delay |
Production capacity | Accepted output and the resource currently limiting it |
Record the cause alongside the number. A failed build caused by an unresolved process issue needs a different response from one started with an incorrect file.
For each proposed benefit, write down the connection between the system, the working practice and the result. For example:
Capturing inspection records against the job reduces the time quality staff spend finding and assembling those records before release.
That is specific enough to test. “Better visibility improves efficiency” leaves too much unexplained.
Separate cash savings, released time and additional business
These benefits can all matter, but they affect the business differently.
Cash savings reduce expenditure
Examples include lower overtime payments, reduced contractor bills or fewer material purchases associated with avoidable scrap.
Use the expenditure that would actually change. If a task takes less time but the same salaries are paid, the payroll saving is zero.
Similarly, a lower allocated machine cost does not necessarily mean the business spends less cash. Identify whether consumables, energy, purchased services or another expense will change.
Released staff time creates capacity
Less administration can give engineers, planners and quality staff more time for other work.
Measure the hours and explain how the team will use them. They might support process development, customer requests or an existing backlog.
You can assign a labour-cost value to those hours for planning purposes, but show it separately from cash savings. Otherwise, a useful operational improvement can become an overstated financial claim.
Additional output needs a customer and a margin
More available production time becomes a financial benefit when it supports work the business can sell and deliver profitably.
Estimate the additional orders, their selling value and the extra costs of producing them. Include material, external processing, labour and other costs that increase with the work.
Check the full route. Additional printing capacity has little commercial value if machining or inspection cannot accommodate the extra parts.
For a cash-flow model, also include when customers pay and when the additional production costs fall due.
Include the full cost of putting the system to work
Build the cost estimate around the proposed rollout, with clear ownership of each item.
Include the relevant costs of:
Software licences or subscriptions.
Configuration and implementation.
Integrations and data migration.
Devices or connectivity.
Training and deployment support.
Additional internal labour or operational cover.
Ongoing support and maintenance.
Some charges may already be included in the supplier’s offer. Confirm the scope so they are neither omitted nor counted twice.
Track existing staff time needed for workshops, testing and training alongside the cash budget. It is a real demand on the business, even when it creates no additional payroll payment. If you value that time as an opportunity cost, identify it separately from the cash-flow calculation.
Our guide to comparing the cost of an additive MES provides questions for checking setup, integration, support and recurring charges across proposals.
Also establish what changes the price: additional users, machines, sites, transactions or a wider implementation scope. Use the expected operation over your chosen period, rather than assuming the initial pilot price covers everything.
Give every benefit an owner and an evidence source
A benefit estimate needs somebody who can explain and verify it.
For each line in the business case, record:
The current cost or workload.
The proposed change.
The expected improvement and its evidence.
When the benefit should begin.
Who will check the result.
Use evidence from representative testing, measured tasks or comparable work within your operation.
If report preparation is a target, time the existing task and repeat it using the proposed workflow. Include corrections, missing records and any supplier assistance needed during testing.
Then consider how often that task occurs. A saving on one straightforward job should not automatically be applied to every job in the annual forecast.
Our guide to running an additive manufacturing workflow software pilot explains how to define acceptance criteria and record both results and unresolved questions.
Keep other changes visible. If the business introduces new equipment or changes staffing during the same period, separate their contribution from the MES benefit as far as practical.
Avoid counting the same improvement twice
Several appealing benefit lines can describe the same underlying change.
Time saved finding production information might appear under administration, report preparation and audit support. Count the distinct tasks and check where they overlap.
A reduction in scrap may release machine time as well as reduce material consumption. Both effects can be relevant, but the financial model must explain how each becomes a benefit.
For example, count the avoided material expenditure and the additional margin earned from using released capacity for other orders. Do not also count the full selling value of the scrapped part as though it were another saving.
The same applies to staff time. If released hours generate additional orders, avoid counting their full labour-cost value again as a separate cash saving.
Work through a defined ROI period
For a straightforward cash-based comparison, use:
Simple ROI (%) = (total cash benefits − total project cash costs) ÷ total project cash costs × 100
State the period beside the result. A three-year ROI is a cumulative result across three years, not an annual return.
The following example uses invented figures to demonstrate the method. They are not Authentise prices or expected customer results.
Assume a manufacturer estimates:
Input | Illustrative amount |
Upfront implementation cash cost | £18,000 |
Annual running cash cost | £12,000 |
Annual avoided overtime and contractor payments at full use | £8,000 |
Annual reduction in material and purchased-service costs at full use | £4,000 |
Annual net cash benefit from additional paid orders at full use | £12,000 |
The additional-order benefit is after the extra production costs needed to fulfil those orders. It is separate from the expenditure reductions in the other lines.
Total annual cash benefits at full use are therefore £24,000.
Allow for rollout and adoption. In this example, the business expects to achieve 75% of that benefit in year one, while paying the full £12,000 annual running cost. Upfront costs are paid before the first year begins.
Period | Cash benefits | Project cash costs | Net cash flow | Cumulative net cash flow |
Before rollout | £0 | £18,000 | −£18,000 | −£18,000 |
Year 1 | £18,000 | £12,000 | £6,000 | −£12,000 |
Year 2 | £24,000 | £12,000 | £12,000 | £0 |
Year 3 | £24,000 | £12,000 | £12,000 | £12,000 |
Total | £66,000 | £54,000 | £12,000 | — |
The three-year calculation is:
(£66,000 − £54,000) ÷ £54,000 × 100 = 22.2%
This example excludes tax, inflation and discounting. Existing salaried staff capacity is recorded separately; any additional implementation labour payments belong in the project costs.
For a formal investment decision, use your finance team’s treatment of those items and the company’s appraisal period.
Calculate payback from the cash-flow timeline
Payback answers a different question: when does the project recover its initial cash outlay?
In the worked example, £12,000 remains unrecovered after year one. Year two contributes another £12,000 after running costs, bringing the cumulative balance to zero at the end of year two.
The simple payback is therefore two years from the start of year one, under the example’s timing assumptions.
For your own model, use monthly cash flows where implementation dates, subscription payments or customer receipts materially affect the answer. If spending begins before go-live, include that period when reporting payback from the initial investment.
A short payback does not describe the project’s whole-life value. It also does not account for the time value of money. ACCA’s explanation of payback and discounted payback covers that distinction.
Test the assumptions that could change the decision
A business case becomes more useful when it shows what happens if the forecast is wrong.
Start with the assumptions carrying the most uncertainty: order volume, adoption timing, avoidable costs and additional implementation work.
Using the same example, keep total project costs at £54,000 and retain the 75% first-year benefit assumption:
Scenario | Annual benefit at full use | Total three-year benefits | Three-year simple ROI |
Lower benefit | £18,000 | £49,500 | −8.3% |
Base case | £24,000 | £66,000 | 22.2% |
Higher benefit | £30,000 | £82,500 | 52.8% |
The lower case does not recover the project’s cash costs within three years. That helps the team identify how much confidence it needs in the benefit estimate.
Test implementation delays and cost increases separately too. A late integration can defer benefits while recurring charges continue.
The next action should follow the uncertainty. If additional order margin drives the result, check demand and downstream capacity. If administration savings drive it, measure those tasks more closely.
Keep important operational benefits visible
Some benefits deserve attention even when a reliable financial value is difficult to assign.
These may include more complete production records, easier retrieval of part history, clearer responsibility for approvals or less dependence on one person’s memory.
Describe the expected change and how it will be checked. Do not assign an invented value to an avoided audit failure or compliance incident just to improve the ROI percentage.
A business can choose to invest partly for better control or customer requirements. Keeping that reasoning visible makes the decision easier to review.
Where FlowsAM fits in the calculation
Authentise FlowsAM connects planning, scheduling, production tracking, traceability and reporting.
For an ROI assessment, connect those capabilities to a measured task or cost. Report generation might reduce preparation work. Connected production records might reduce status chasing. Scheduling support might help the team use available capacity more effectively.
Test the relationship in the proposed workflow, including the integrations and user actions it depends on.
The business case should show which benefits have been demonstrated, which remain estimates and what needs to happen for each estimate to become a result.
Review the return after implementation
Keep the original assumptions and compare them with actual performance after rollout.
Check whether users follow the intended workflow, whether the required integrations work and whether the expected costs changed. Include support effort and any work that moved to another department.
Where results differ, investigate the cause before revising the forecast. A lower order volume, incomplete rollout and an unsuitable workflow call for different responses.
Start your additive MES business case with a small number of measurable problems, a complete cost estimate and an owner for each benefit. That gives production and finance a shared basis for deciding what to test, what to invest and what to expect.
