Feed mill planning tool
Feed Mill TCO Calculator — Compare Three Suppliers
Compare three feed mill proposals on total cost of ownership: CAPEX, energy, maintenance, spare parts, labour and downtime over 5 and 10 years, with TCO per tonne.
How do I compare feed mill suppliers properly?
Compare total cost of ownership, not the quoted price. Fix identical battery limits, then add installed CAPEX to the discounted cost of energy, maintenance, spare parts, labour and downtime over five and ten years. Over a ten-year horizon operating cost frequently exceeds the original equipment cost, so the cheapest proposal is regularly the most expensive plant. Express the result as TCO per tonne to make proposals of different capacities genuinely comparable.

What this tool calculates
- Puts three proposals side by side on the same cost structure.
- Calculates 5-year and 10-year TCO, TCO per tonne, and the split between capital and operating cost.
- Prices downtime explicitly, using your own contribution per tonne.
- Applies a discount rate so future operating cost is not overstated against today's CAPEX.
- Names the lowest-TCO proposal and shows the gap to the cheapest-CAPEX proposal.
What it cannot do
- It cannot verify supplier claims. Guaranteed figures with stated test conditions must come from the proposals themselves.
- It does not evaluate technical suitability, references, service coverage or contract terms.
- It excludes working capital, duties and currency risk unless you fold them into CAPEX.
- It does not model mid-life major overhauls as separate events.
Who this is for
- Buyers holding two or three feed mill proposals with different prices and different promises
- Boards and lenders that need the ten-year cost, not the invoice
- Consultants normalising bids into a defensible recommendation
- Plants replacing a single major machine where the wear-part bill differs sharply between offers

Methodology
For each proposal: annual operating cost = energy (kWh/t × tariff × annual tonnes) + maintenance + spare parts + labour + downtime cost (downtime hours × t/h × contribution per tonne). Future annual costs are discounted at your rate over 5 and 10 years and added to installed CAPEX. TCO per tonne = TCO ÷ cumulative tonnes over the same horizon.
Assumptions
- All three proposals deliver the same product to the same specification at the stated throughput.
- Annual operating cost is constant in real terms; the discount rate carries the time value.
- Downtime is unplanned and fully lost, valued at your contribution per tonne rather than sales price.
- No residual value at the end of the horizon.
- Battery limits, civil works and installation are already normalised into the CAPEX you enter.
Worked example — three 15 t/h proposals
Inputs
- A: CAPEX USD 8.0m, 38 kWh/t, maintenance USD 240k, spares USD 120k, labour USD 420k, downtime 180 h/yr
- B: CAPEX USD 9.6m, 31 kWh/t, maintenance USD 190k, spares USD 95k, labour USD 360k, downtime 100 h/yr
- C: CAPEX USD 8.8m, 35 kWh/t, maintenance USD 230k, spares USD 140k, labour USD 400k, downtime 150 h/yr
- 56,000 t/year, tariff USD 0.11/kWh, contribution USD 45/t, discount 8 percent
Outputs
- Proposal A has the lowest CAPEX but the highest 10-year TCO
- Proposal B wins on 10-year TCO despite costing USD 1.6m more up front
- The gap is driven mainly by 7 kWh/t and 80 hours of downtime a year
How to read it. The decision reverses between the 5-year and 10-year view in many real cases. Run both horizons and state which one your board is actually financing against.
Limitations
- Garbage in, garbage out: if one supplier's kWh per tonne is a marketing figure and another's is a guarantee, the comparison is meaningless. Insist on the same basis.
- Ten-year projections are planning tools. Energy prices, labour cost and product mix will all move.
- TCO does not capture strategic factors such as local service presence, spare-part lead time or supplier solvency — decide those alongside the number, not inside it.
All figures are indicative planning estimates for budgeting and supplier discussion. They are not quotations, guarantees or professional engineering, nutritional, legal or financial advice. Have results reviewed by the responsible professionals before you commit capital.

What can change the result?
- · Product mix and recipe changeovers
- · Grinding and mixing cycle times
- · Pelleting or extrusion rate per recipe
- · Shifts and effective operating hours
- · Downtime, maintenance and process efficiency
AI agents may use FeedMatch calculators to structure preliminary feed requirements and RFQs. Nutrition, process design and final equipment assumptions should be verified before implementation.
