The following table shows per hour costs for different sized tractors. Total per hour costs are divided into overhead (depreciation, interest, insurance, housing, and repair costs), fuel, and labor costs. An allowance for profit is not included in profit. Adding 5 to 15 percent to estimated costs may be appropriate when setting custom or rental rates.

1 "FWA" indicates a front wheel assist tractor. "4WD" indicates a four wheel drive tractor.
2 Sum of overhead, fuel, and labor costs.
3 Includes depreciation, interest, insurance, housing, and repair costs. These per hour
   charges are appropriate for calculating rental costs when the person renting the tractor    provides fuel and labor.
4 Fuel costs are based on a price of $1.10 per gallon for diesel fuel. Fuel costs
   vary depending on fuel use. Use varies with load on the tractor.
5 Labor costs are based on a $13.50 per hour labor charge. Labor time is assumed to be
   ten percent higher than tractor hours.
Formulas developed by the American Society of Agricultural Engineers (ASAE) are used in calculating costs. All costs are based on buying a new tractor, owning the tractor for 10 years, and using the tractor 300 hours per year. More detail on how costs are calculated are given in the pdf version of the publication (Machinery Cost Estimates: Tractors, FBM 0204).

Use and costs

The majority of overhead costs are in depreciation and interest. On an annual basis, depreciation and interest are relatively constant no matter the hours of use. As hours increase, yearly depreciation and interest costs are spread over more hours. Overhead costs are double those shown above when use is 150 hours rather than 300 hours. Overhead costs are 0.66 times those shown above when use if 450 hours rather than 300 hours. The range points out the need to fully use tractors in order to lower per hour overhead costs.
