Feed mill planning tool
Feed Mill Automation ROI Calculator
Estimate the return on a feed mill automation upgrade: labour saved, dosing accuracy and micro-ingredient give-away recovered, downtime avoided, annual saving and simple payback in months.
Is a feed mill automation upgrade worth the investment?
An automation upgrade pays back through four measurable lines: labour hours removed from manual batching and record-keeping, raw-material give-away recovered when dosing accuracy improves, downtime avoided through faster changeovers and fault diagnosis, and rework or rejected batches avoided through traceability. Quantify each against annual tonnage and the upgrade cost, and the honest test is simple payback in months — most credible batching and PLC retrofits land between 12 and 36 months at commercial tonnage. Below roughly 15,000 tonnes a year, automation is usually justified by traceability and compliance rather than by cost saving.

What this tool calculates
- Converts labour hours removed by automation into an annual cost saving at your loaded labour rate.
- Quantifies raw-material give-away recovered when batching accuracy improves, priced at your average blend cost.
- Values downtime hours avoided at your contribution margin per tonne.
- Values rework and rejected batches avoided through traceability and recipe control.
- Returns annual saving, simple payback in months and a five-year net position on the upgrade.
What it cannot do
- It cannot price your specific automation scope — hardware, licences, engineering and commissioning are quoted per site.
- It cannot model the commissioning period, when output usually dips before it improves.
- It cannot capture regulatory or customer-audit value, which often decides the project regardless of payback.
- It does not account for financing cost, tax treatment or depreciation.
Who this is for
- Feed mill owners weighing a batching or PLC/SCADA retrofit against other capital
- Production managers who need a defensible number before a board request
- Buyers comparing automation scopes across competing supplier proposals
- Integrators building a business case for traceability across several mills
Input definitions

- Entered by you. Default used for the worked example: 40 batches/yr.
- Batch size (t)
- Entered by you. Default used for the worked example: 5 t.
- Rework cost per tonne (USD/t)
- Entered by you. Default used for the worked example: 60 USD/t.
Methodology
Annual saving = (labour hours saved per day × operating days × loaded hourly rate) + (annual tonnage × blend cost per tonne × give-away reduction) + (downtime hours avoided × throughput t/h × contribution margin per tonne) + (batches reworked avoided × batch size × rework cost per tonne). Simple payback in months = upgrade cost ÷ annual saving × 12. Five-year net = annual saving × 5 − upgrade cost.
Assumptions
- Give-away reduction is expressed as a percentage of raw-material value, not of formula weight — micro-ingredients dominate the value even at small weight shares.
- Labour saving assumes the hours are genuinely removed or redeployed, not simply reassigned within the same headcount.
- Contribution margin, not sales price, is used for lost production — variable cost is not incurred on tonnes never produced.
- The upgrade cost is treated as a single capital sum in year zero, with no financing charge.
Worked example — batching and PLC retrofit on a 10 t/h mill
Inputs
- Upgrade cost USD 320,000; annual tonnage 48,000 t; blend cost USD 380/t
- Labour saved 4 h/day at USD 14/h loaded, 300 operating days
- Give-away reduction 0.35%; downtime avoided 90 h/year at 10 t/h and USD 22/t margin
- Rework avoided 40 batches/year at 5 t and USD 60/t
Outputs
- Labour saving about USD 16,800/year
- Give-away recovery about USD 63,840/year
- Downtime value about USD 19,800/year
- Rework avoided about USD 12,000/year
- Annual saving about USD 112,440 — simple payback about 34 months
How to read it. Give-away recovery carries the case, so it is the number the supplier must guarantee. Ask for the dosing tolerance in writing per scale range, and structure acceptance testing around weighed batches rather than around a screen showing the setpoint.
Limitations
- Give-away reduction is the most sensitive input. Verify current dosing accuracy with weighed check batches before trusting a large figure.
- Payback below 12 months usually indicates an over-optimistic give-away or downtime assumption, not an exceptional project.
- Savings realised in year one are typically lower than steady-state because of operator learning.
