Equipment Ownership Cost Calculator

How It Works

1. Enter Machine Acquisition Data

   Input purchase price, salvage percentage, useful life hours, planned annual use, and carrying costs. The local calculation uses straight-line economic depreciation and average-investment cost of capital for screening only.

2. Set Finance and Fixed Costs

   Enter the financing or opportunity-cost rate, annual insurance, storage, and property tax or license cost. Verify these against your lender, accountant, insurance policy, and local tax treatment before using the rate outside planning.

3. Enter Operating Cost Inputs

   Input measured or quoted fuel consumption, fuel price, tire/track or wear-part cost, useful life for those wear parts, repair factor, and optional operator rate. Replace the app presets with actual fleet records whenever available.

4. Review the Source Gaps

   Use the ownership, operating, and own-vs-rent sections as a screening output. Then reconcile the result with current USACE, FEMA, FHWA, state DOT, rental, OEM, contract, and accounting sources that apply to the job.

Built For

• Contractors preparing a preliminary internal equipment rate before source review
• Fleet managers comparing owned-equipment cost assumptions against rental quotes
• Estimators checking whether fuel, repair, and carrying-cost assumptions dominate a bid
• Project teams documenting the inputs that still need contract, owner, DOT, or agency review
• Equipment buyers building an estimate before dealer, lender, and accounting validation

Features & Capabilities

Transparent Ownership Calculator

Separates purchase price, salvage value, useful life, annual utilization, carrying cost, insurance, storage, and tax assumptions so they can be reviewed line by line.

Own vs. Rent Calculator

Compares the local hourly ownership result against a daily rental rate entered by the user. The output is an estimate only because real rental contracts can include delivery, pickup, standby, fuel, damage waiver, availability, and minimum-period rules.

Operating Cost Detail

Breaks operating costs into fuel, lubricant allowance, tires/tracks or wear parts, repair and maintenance, and optional operator cost. Each line remains editable so fleet history can replace generic presets.

Assumptions

• Depreciation is computed using a straight-line economic method over useful life hours to the estimated salvage value. Tax depreciation and book depreciation may differ.
• Cost of capital uses the average investment method: (purchase price + salvage value) / 2 times the annual rate, spread across annual hours.
• Fuel consumption is assumed constant at the rate entered. Actual consumption varies with load factor, idle time, altitude, temperature, undercarriage condition, operator technique, and application severity.
• Repair and maintenance are estimated as repair factor times hourly depreciation. The local preset repair factors are not current USACE, EquipmentWatch, OEM, or dealer rows.
• The calculator excludes or separately handles mobilization, demobilization, standby, idle rules, attachment rental, damage waivers, rental minimums, financing covenants, tax effects, and contract reimbursement rules.

Limitations

• Does not model variable repair cost curves over the machine's life. In reality, repair costs increase as the machine ages, with major component overhauls (engine, transmission, hydraulic pumps) concentrated in the second half of economic life.
• Does not account for downtime costs (idle crew labor, schedule delays) when the machine is out of service for repair.
• Does not calculate tax depreciation (MACRS, Section 179, bonus depreciation) or the after-tax cost of ownership. Consult your accountant for tax impact analysis.
• Does not include technology or regulatory obsolescence risk, which can shorten economic life for machines affected by emissions standards (Tier 4 engine requirements).
• Does not certify rates for USACE, FEMA, FHWA, state DOT, owner, force-account, claim, or reimbursement use.
