Start / Machinery and application / Machinery cost
Enter the machine's value, consumption, and work rate to find out what each hour of work and each hectare operated costs.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
Hourly cost breakdown in R$/h: ownership costs (depreciation, interest, insurance) and operating costs.
Interest and insurance are spread out when the machine works more hours; the point marks your use.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Cost per hour and per hectare of the machine for different hours of use per year, with the purchase value, useful life and output entered.
The calculation done in steps, with the values you entered.
The calculation memo gathers this page's inputs, results, equations, assumptions, and references, with fields for project, responsible person, and review. The full report also includes the charts and interpretations, in color. In the print window, choose Save as PDF.
Enter the machine's value, residual value, useful life in hours, and hours worked per year. Then add interest, insurance, repairs, fuel consumption and price, lubricants, operator cost, and the work rate in hectares per hour. The calculator returns the cost per hour, the cost per hectare, and the breakdown of each component.
Tractor at R$ 350,000 with 20% residual value, 12,000 h life, 800 h/year, 8% annual interest, 1% insurance, repairs at 80% of the value over its life, fuel use of 14 L/h at R$ 6.00, lubricants at 10% of fuel cost, operator at R$ 20/h and output of 1.5 ha/h.
Depreciation R$ 23.33/h; interest R$ 21.00/h; insurance R$ 4.38/h; repairs R$ 23.33/h; fuel R$ 84.00/h; lubricants R$ 8.40/h; operator R$ 20.00/h. Total of R$ 184.44/h and, at 1.5 ha/h, R$ 122.96 per hectare.
| Installment | Calculation (R$/h) |
|---|---|
| Depreciation | (value − residual) ÷ useful life in hours |
| Interest | (value + residual) ÷ 2 × annual interest ÷ hours per year |
| Insurance and shelter | value × annual rate ÷ hours per year |
| Repairs and maintenance | value × % repairs over life ÷ useful life in hours |
| Fuel and lubricants | fuel use (L/h) × price × (1 + % lubricants) |
| Operator | hourly wage with charges |
The depreciation in this calculation is economic: how much value the machine loses per hour of use. It is not tax depreciation, which follows rates set by the Brazilian Federal Revenue for tax purposes. Use the real useful life of your machine, which depends on the type of work and the maintenance.
Take the cost per hectare of operations to the production cost per hectare. For applications, also see the sprayer setting.
Add depreciation, interest, insurance and shelter, repairs, fuel, lubricants and the operator. The total is the cost per working hour.
Divide the hourly cost by the operational yield in hectares per hour. Lower yields make each hectare more expensive.
Add depreciation, interest, insurance and shelter, repairs, fuel, lubricants and labor, all in R$ per hour. Ownership costs per hour depend on how many hours the machine works per year.
Compare the cost per hectare calculated here with the price of the outsourced service. If the machine works few hours per year, fixed costs weigh heavily and hiring tends to be cheaper; if it works a lot, buying usually pays off.
It is how much the machine is worth at the end of its useful life. It depends on the type, the use and the used-equipment market: check quotes for similar machines in your region instead of using a generic percentage.
Measure the refueling at the end of several hours of work in real operation and divide by the hours. The catalog value is usually for full load and can exceed the average consumption of light operations.
Parts, shop labor and servicing over the useful life, as a percentage of the purchase price. Routine lubricants and filters have their own field in this calculator.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods. They do not replace a design, a calculation report or a report signed by a qualified professional (CREA/ART), nor verification against the applicable technical standards and legislation, such as the Regulatory Standards of the Ministry of Labor. Material and fuel properties vary: check with the manufacturer or with analyses of your process before deciding. By using the site, you agree to the Terms of Use.
