Farm machinery costs make up a significant part of the fixed and variable costs of any farm operation. If the capital invested in a machine is to be used efficiently, that machine must be used over enough acres or for enough hours to have costs comparable to or below the same operation being done by a custom operator.

This factsheet provides a framework for calculating the total annual cost of farm machinery so that you can determine whether it makes economic sense for you to own a machine. The best source of information to budget farm machinery costs is your records. In the absence of farm records, calculation methods can be used to estimate the costs.

The information presented is prepared as a representative guide to estimating machinery costs and is not intended to recognize or predict the costs for any one particular operation. Terms are explained in more detail in the section on Machinery cost budgeting terms.

Some values in this factsheet are in imperial measurements, reflecting common usage in the industry.

Machinery cost basics and calculations

Machinery costs include fixed (ownership) costs and variable (operating) costs. These costs affect the profitability of the business.

Fixed costs

Fixed costs do not change as the machine sees more use. They include depreciation, interest, insurance and housing. Fixed costs per unit of work done drop as the hours or acres of use per year increase.

Depreciation is a measure of the loss of value of a machine over time. Total depreciation is calculated by subtracting the trade-in (or salvage) value of the machine from the purchase price. The trade-in value or salvage value is the estimated value of the machine at the end of its years of service or optimal life. Optimal life is defined as when the equipment value has declined to one-third of its original purchase price. Straight line depreciation divides the total depreciation in equal amounts over the life of the asset. Estimated optimal life, annual hours of use and annual depreciation rates for selected farm equipment are shown in Table 1. Inflation, equipment supply/demand and current farm economy factors can cause wide variation in trade-in values.

Interest cost is the interest charged by your lender or on the owned capital you have invested in the machine. If the machinery is partially financed by a lender and partially your own capital, use the average of the two rates. The owned capital investment interest rate used should reflect conservative rates of return for money that could be obtained in the current market, e.g., T-Bill rate, GIC rate. If capital is in tight supply, you may want to choose a higher rate that gives you more of a return for the risk you assume in the investment. The interest rate used should be adjusted for inflation since inflation reduces the real cost of investing in farm machinery. If the average interest rate is 5% and inflation is at 2%, the adjusted or “real” interest rate is 3%.

The capital recovery method estimates the annual depreciation and interest costs. It combines depreciation and interest costs in one calculation. To calculate the capital recovery costs, the capital recovery factor is multiplied by total depreciation and adds the result of the trade-in value multiplied by the interest rate. Table 2 provides the capital recovery factors for selected combinations of years and interest rates.

Insurance and housing make up a small part of the ownership costs of a machine. Insurance costs are calculated by adding the purchase price plus the trade-in value of the machine, dividing by two to give an average value over the machine’s life, then multiplying by the chosen insurance rate. Housing costs are estimated by multiplying the housing rate per square foot by the square feet of housing required. The current market building rental rate per square foot is a good estimate for the housing rate. Housing requirements of selected farm equipment are shown in Table 3. If the insurance and housing rates are not known, 1% of the purchase price can be used to estimate annual insurance and housing costs.

Variable costs

Variable costs increase as the machine sees more use and include repairs, fuel and lubricants, and labour.

Repair costs are relatively low early in the life of a machine, but repair costs rise quickly as a machine sees more hours of use. Figure 1 shows how repair costs accumulate for four-wheel-drive tractors. For example, at 4,000 hr, accumulated repair costs are estimated to be 4.8% of the purchase price while they rise sharply to 43.2% by 12,000 hr. Averaging these repair costs over the machine’s life can provide a reasonable estimate of annual repair costs. Annual repair rates as a percent of purchase price are shown in Table 1. Storing machines inside helps reduce the rate of weathering and wear, and also slows down the visible signs of aging.

Fuel, oil and lubrication costs vary with the annual use of the machine and its maintenance schedule. Lubrication costs add approximately 10% to fuel costs. The best source of information for fuel use is past records.

If these records are unavailable, calculate annual fuel consumption using the following method:

Average Diesel Consumption (L/hr)
= (0.244) × maximum PTO horsepower/hour (HP-hr)

The diesel fuel rate is based on fuel consumption results published by the Nebraska Tractor Test Laboratory, University of Nebraska, for tractors tested from 2008 to 2017. Diesel units will use less fuel than gasoline units. Multiply the diesel fuel consumption rate by 1.37 to estimate gasoline fuel consumption.

Average Gasoline Fuel Consumption (L/hr) = (0.244) × maximum PTO HP-hr × (1.37) or
= (0.334) × maximum PTO horsepower

The maximum PTO horsepower per hour can be obtained from the Nebraska Tractor Test Data, published by the Nebraska Tractor Test Laboratory. If the maximum PTO horsepower for a particular tractor is not known, the advertised PTO horsepower per hour or the Nebraska Tractor Test Data for a tractor with similar displacement can be used.

Table 4 shows the performance, fuel and horsepower requirements of selected farm equipment.

Fuel and lubrication costs
= litres of fuel used/hr × hr of use/year
x fuel cost/L × 1.10

This table does not account for the variation in rates of work or horsepower requirements caused by differences in soil type, topography, field shape, and drainage or equipment operators.

Labour costs are a consideration in any budget, but the value used will depend on the situation. Estimate the labour rate for the owner/operator using the opportunity cost for use of time. A constant rate for hired labour is appropriate. The rate should not be less than the typical labour rate for the area. Add labour costs where you feel it is justified.

There is one fundamental rule that must be followed to justify the ownership of any machine: use it. Machinery is expensive and ties up large amounts of capital. If a machine is to be cost-effective, it must see enough hours of use annually to have fixed and variable costs below the cost of the same operation being done via alternatives to purchasing.

Consider the combine shown in Table 5 at three different levels of annual use.

This does not account for the issue of when the custom operator can arrive at your farm. For many, the benefits have to be better than break-even for them to hire a custom operator over ownership due to the control over when the crop is harvested. This same principle applies for any farm operation that requires timely access to machinery. Delays to planting or harvesting can have a significant affect on yield and quality.

Used machinery

When calculating the depreciation on used machinery, use the actual price paid for the machine minus its expected trade-in or salvage value, divided by the expected life of the machine on your farm. Increase repair rates to levels appropriate for the age or number of hours on the machine. Expect to have higher-than-normal repair expenses in the first year of ownership of a used machine as you bring it back into top operating shape.

Annual cash costs based on repayment

Cash costs estimate the impact of the purchase and its use on annual cash flow. Tax savings can be considered when applicable. If we take the debt servicing requirements of the combine in Table 5, assuming 50% of the purchase price is covered by a trade-in and/or cash payment and add insurance and housing costs, here is what the annual cash fixed costs of this machine would be:

The resulting change in break-even when considering annual cash costs is shown in table 6.

Highly profitable operations would be able to justify covering fewer acres because of the additional tax savings from the capital cost allowance (CCA) on the combine. CCA expense for this machine in the first year at 45% would be $297,000 and in the second year at 30% would be $108,900. Tax savings, depending on the marginal tax rate of the individual or corporation that owns the machine, could range from zero to about $128,185 in year 1 and $47,000 in year 2 at the highest marginal tax rate. The Accelerated Investment Incentive allowing the 45% deduction in Year 1 will be available until December 31, 2023. The incentive will be gradually phased out in the years 2024 to 2027.

The break-even for purchasing versus hiring a custom operator in this case is around 2,100 acres.

Alternatives to purchasing machinery

The three most common alternatives to purchasing machinery are leasing, hiring custom farmwork or equipment rental.

Leasing farm equipment

Leasing has become a popular option to consider when acquiring farm machinery. The popularity of leasing is in part due to the increasing cost of machinery, the outlay of large amounts of capital and managing cash flow. The decision to lease or purchase depends on a number of factors, cash flow being an important one. Lease payments are usually lower than loan payments, reducing cash flow requirements. If cash flow is tight, leasing may be more attractive. This is especially true if investment elsewhere in the business can return a higher rate than the cost of the lease. See the OMAFRA Factsheet Lease Agreements — Farm Equipment.

Custom farmwork and machinery rental

Hiring custom farmwork provides an option to farmers to purchase the service instead of owning the equipment and doing the work. Custom farmwork operators are well advised to calculate their own machinery costs to ensure they are covering their costs plus a return for their risk and time.

Machinery rental allows farmers access to equipment for short periods of time when it is needed without the full cost of ownership and operating expenses. A survey of Ontario Custom Farmwork and Equipment Rental Rates is conducted regularly by OMAFRA. The latest Custom Farmwork and Rental Rates Charged in Ontario summary is available from the OMAFRA Agricultural Business Management website at

Machinery cost budgeting terms

Accumulated repair costs
total cost of repairs that have been incurred over the life of the machine to date.
Capital cost allowance
an amount (expressed as a %) allowed to be expensed for tax purposes against the cost of capital assets acquired by a business. Different types of assets attract different percentages.
Capital recovery method
The American Society of Agricultural Economists recommends the use of the capital recovery method in their Commodity Costs and Returns Estimation Handbook to calculate depreciation and interest. This method calculates interest on investment and depreciation combined. The capital recovery method calculates an annual machinery cost that recovers the value of the machinery within a specified period at a designated rate of interest.
Depreciation, straight line
a method in which equal amounts of depreciation expense is budgeted for each time period over the life of the asset.
Insurance rate
percentage of the value charged by commercial insurance companies to insure the machinery investment.
a contract for the use of machinery for an agreed period of time in return for periodic payments. Ownership remains with the lessor. The lessee acquires the right of temporary possession and use.
Nebraska Tractor Test Data
Tractors are tested at the University of Nebraska Tractor Test Laboratory under similar conditions to provide a means of comparison of performance of different tractor makes and models.
Operating costs
variable costs, costs that depend directly on the amount of machine use.
Opportunity cost
the potential benefit that is lost by choosing one good or service at the expense of giving up another good or service. For example, if a farmer could earn a salary of $48,000 by working off the farm, $48,000 would be the opportunity cost of choosing to work on the farm.
Optimal life
when the equipment value has declined to one-third of its original purchase price. The salvage value at the end of the optimal life is assumed to be 33% of the purchase price, but the years of service varies by equipment type.
Ownership costs
fixed costs, costs that do not depend on the amount of machine use.
Total annual cost
the sum of fixed (ownership) and variable (operating) costs.
