Question 1

How does per-mile depreciation work?

Accepted Answer

Per-mile depreciation uses the units-of-production method applied to vehicles. The depreciable cost is divided by total estimated lifetime miles to get a cost-per-mile rate. Each period's depreciation equals the rate multiplied by actual miles driven, tying expense directly to vehicle usage.

Question 2

What is the difference between the IRS standard mileage rate and actual depreciation?

Accepted Answer

The IRS standard mileage rate is a simplified per-mile deduction covering fuel, maintenance, insurance, and depreciation combined. Actual depreciation calculates only the vehicle's value decline based on usage. Businesses must choose one method and may find actual depreciation more beneficial for expensive vehicles.

Question 3

What is the average depreciation cost per mile by vehicle type?

Accepted Answer

Average depreciation per mile varies significantly by vehicle type. Compact cars typically depreciate at $0.08 to $0.15 per mile, SUVs at $0.12 to $0.20, and commercial trucks at $0.15 to $0.30. Luxury vehicles often have higher per-mile costs due to steeper initial value decline.

Question 4

How do you calculate depreciation based on odometer readings?

Accepted Answer

Record the odometer reading at the start and end of each period. Subtract to find miles driven, then multiply by the per-mile depreciation rate. The rate equals the depreciable cost (purchase price minus salvage value) divided by the total estimated lifetime mileage of the vehicle.

Question 5

Why is the per-mile method useful for fleet management?

Accepted Answer

The per-mile method accurately reflects each vehicle's actual wear and tear, making it ideal for fleets with varying usage levels. It helps fleet managers allocate costs fairly across vehicles, identify underperforming assets, and make data-driven decisions about vehicle replacement timing.
