Formula
Annual Depreciation = (Purchase Price - Salvage Value) / Useful Life; Cost per Hour = (Depreciation + Maintenance) / Annual Hours
The straight-line depreciation method subtracts the expected salvage value from the purchase price and divides by the useful life in years. Adding annual maintenance and repair costs gives the total annual ownership cost. Dividing by the number of operating hours per year produces the hourly ownership cost rate used for project bidding.
Worked Examples
Example 1: Excavator Ownership Cost
Problem: Calculate the hourly cost for an excavator purchased at $120,000 with a $15,000 salvage value, 8-year useful life, $4,000 annual maintenance, used 1,800 hours per year.
Solution: Annual depreciation = ($120,000 - $15,000) / 8 = $13,125\nAnnual ownership cost = $13,125 + $4,000 = $17,125\nCost per hour = $17,125 / 1,800 = $9.51
Result: $9.51 per hour ownership cost
Example 2: Compact Loader Cost Analysis
Problem: A compact loader costs $45,000, has $5,000 salvage value after 6 years, $2,500 annual maintenance, and runs 1,200 hours per year.
Solution: Annual depreciation = ($45,000 - $5,000) / 6 = $6,667\nAnnual ownership cost = $6,667 + $2,500 = $9,167\nCost per hour = $9,167 / 1,200 = $7.64
Result: $7.64 per hour ownership cost
Frequently Asked Questions
How is equipment depreciation calculated in construction?
Equipment depreciation is most commonly calculated using the straight-line method, which divides the difference between the purchase price and salvage value by the useful life in years. For example, equipment costing $100,000 with a $10,000 salvage value over 10 years depreciates at $9,000 per year. Some contractors use the declining balance method for tax purposes, which front-loads depreciation in earlier years when the equipment is newer and more productive.
What factors affect the total cost of owning construction equipment?
The total cost of owning construction equipment includes the purchase price, financing costs, insurance, taxes, storage, maintenance, repairs, fuel, and operator wages. Depreciation is typically the largest single component, followed by maintenance and fuel costs. Equipment that sits idle still incurs ownership costs like depreciation and insurance, which is why utilization rate is critical to profitability. Contractors must also consider the opportunity cost of capital tied up in equipment.
What is a good cost per hour for construction equipment?
A good cost per hour varies significantly by equipment type and size. Small skid steers may cost $25-$50 per hour to own and operate, while large excavators can run $75-$150 per hour. Cranes and specialized equipment can exceed $200 per hour. To remain profitable, contractors should ensure that the billing rate for equipment on projects exceeds the ownership and operating cost per hour by at least 15-25%. Tracking actual utilization hours helps refine these cost estimates over time.
How do I decide between buying and renting construction equipment?
The buy-versus-rent decision depends on utilization rate, project duration, and cash flow. If you will use the equipment more than 60-70% of available working hours throughout the year, buying is generally more economical. For short-term or specialty needs under a few months, renting avoids the capital outlay and maintenance responsibility. Calculate the break-even point by dividing the annual ownership cost by the daily or monthly rental rate to find how many rental days equal the cost of owning.
How accurate are the results from Equipment Cost Calculator?
All calculations use established mathematical formulas and are performed with high-precision arithmetic. Results are accurate to the precision shown. For critical decisions in finance, medicine, or engineering, always verify results with a qualified professional.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
