Will Your Oil Mill Make Money?
Enter your own local numbers — raw material price, oil selling price, cake price — and get monthly gross margin and payback period. We do not preload prices: yours are the only ones that matter. Treat press cake as potential revenue only after local price, quality requirements and buyer acceptance are confirmed.
💰 Oil Mill ROI / Payback Calculator
Reading the result honestly
This is a gross-margin planner, not a business plan: it ignores taxes, financing cost, spoilage and price seasonality. If payback shows under 12 months, your plan has room for those surprises. If it shows 30+ months, improve one of the three levers — buy seed cheaper in season, sell oil branded/retail instead of bulk, or make sure cake revenue is not left on the table.
The three levers, with a worked example
Say a mill processes 1,000 kg of groundnut per day at $0.60/kg seed cost, yields 40% oil selling at $2.20/kg, and sells cake at $0.35/kg over 25 working days. Revenue: 400 kg oil × $2.20 = $880 plus 600 kg cake × $0.35 = $210, so $1,090/day or $27,250/month. Seed costs $15,000/month; with $900 running costs the gross margin is about $11,350. Those numbers are illustrative only — swap in your own — but they show the structure: cake contributed 19% of revenue, and margin swings hardest with seed price.
Lever 1 — seed price: buying in harvest season at even $0.05/kg less adds $1,250/month here; that is why serious mills budget storage working capital, not just machinery. Lever 2 — selling format: bulk crude to traders is the lowest price; filtered and bottled for local retail typically clears meaningfully more per liter, and the filtration equipment often pays for itself on that spread alone. Lever 3 — cake: in groundnut and sunflower regions cake demand from feed mills is steady; leaving it unpriced in your plan understates the whole business.
Costs first-time millers underestimate
First-year planning should include seed working capital, consumables and maintenance, packaging, commissioning losses and downtime. Use supplier quotations and local operating evidence instead of fixed universal allowances.
Next steps: size the machine, read the buying guide, and watch the machines run on real seed.
ROI assumptions register
A useful business case keeps market inputs, operating assumptions and equipment investment separate. Record the source and date for every value so the calculation can be reviewed.
Revenue inputs
Local oil selling price, saleable oil volume, cake value, by-product acceptance and expected sales mix.
Variable costs
Seed purchase, transport, electricity or fuel, water, packaging, consumables and waste handling.
Fixed and operating costs
Labor, rent, maintenance reserve, quality control, downtime and local compliance costs.
Investment and cash
Equipment, freight, installation, civil work, working capital, finance, tax and contingency.
Read the result correctly
Gross margin is revenue minus the operating costs entered. Payback compares investment with modeled cash contribution. Neither figure is net profit unless finance, tax, depreciation, working capital and all local costs are included.
Frequently Asked Questions
Because they swing by country and season, and a calculator with stale prices produces confident nonsense. Your local numbers are the only honest input.
Cake can be a saleable by-product where local buyers, specifications and regulations allow it. Enter revenue only when price, quality requirements and a realistic buyer route are documented.
Electricity (press motor + roaster), labor, rent, packaging, and a maintenance reserve for pressing worms/bars — they are consumables.
Check seed-price seasonality, working-capital needs, oil-price competition, commissioning losses, downtime, finance and tax. Build low, base and high cases from dated local evidence.
