Machinery Cost Calculator & Cost per Hour & Acre

Add the fixed cost (depreciation, interest on the money tied up, insurance and housing) spread over the hours you use it, to the operating cost (fuel, lubricants, repairs and labour) per hour. A tractor used few hours a year has a high fixed cost per hour even if fuel is cheap. This tool computes the full figure.

Fixed (ownership) costs accrue whether or not the machine works — depreciation, interest, insurance, shed/housing. Operating costs only happen when it runs — fuel, oil, repairs, operator labour. Fixed cost per hour falls the more you use the machine; operating cost per hour stays roughly constant.

This tool uses straight-line depreciation: (purchase price − salvage value) ÷ useful life in years. If a ₹8,00,000 tractor with 10% salvage lasts 10 years, it depreciates ₹72,000 a year. Salvage is what you'd sell it for at the end; life is realistic working years, not warranty years.

Because the money sunk into the machine could have earned a return elsewhere (or is borrowed and really costs interest). Economists charge interest on the average investment — (price + salvage) ÷ 2 — to capture this opportunity cost. Ignoring it understates the true cost of ownership.

Divide the total cost per hour by the work rate in acres per hour. A machine costing ₹850/hour that covers 1 acre/hour costs ₹850/acre; at 2 acres/hour it's ₹425/acre. Faster, wider implements spread the cost over more area — the tool shows the effect when you enter the work rate.

Cover your full cost per hour (fixed + operating) plus a margin for profit and risk — commonly 15–25%. The tool's custom-hire rate is total cost × (1 + margin). Compare it to local rates: if local hire is cheaper than your cost, owning may not pay for your hours.

Use the machine more hours a year (spreads fixed cost), do custom work for neighbours to add hours, maintain it well to cut repairs and extend life, and right-size the machine to the job. The biggest lever is annual hours — doubling them nearly halves the fixed cost per hour.

Compare your computed cost per hour (or per acre) against the local hire rate at your actual annual usage. Low-use machines are usually cheaper to hire; high-use machines justify ownership. Factor in timeliness too — owning means the machine is there when the weather window opens.

Repairs rise with age and use. A common estimate is annual repairs of about 3–7% of the purchase price; this tool uses your repairs percentage spread over annual hours. Good servicing lowers it and extends life, improving both operating and fixed cost per hour.

Yes — tractor, combine, rotavator, power tiller, pump set or any owned machine. Enter that machine's price, life, hours, fuel and repairs. For implements with no engine, set fuel to zero and the tool still gives ownership cost per hour and per acre.
