Frequently asked questions
- What should fleets include in TCO?
- A defensible fleet TCO includes vehicle purchase or financing, fuel (after fuel-card discounts and expected price inflation), maintenance per mile plus tires and repairs, downtime cost while a unit is out of service, depreciation against expected resale, and any insurance or telematics line items. Leaving out downtime or depreciation is the most common way operators understate true cost per mile.
- Is fuel the largest fleet operating cost?
- For most over-the-road and regional fleets, fuel and depreciation each run 30–45% of total cost, with maintenance and downtime making up the rest. For low-mileage urban fleets or EVs, depreciation typically beats fuel as the single biggest line item. Run your own miles, MPG, and resale through the model — the rank order flips fast.
- How do fuel cards affect fleet TCO?
- Cents-per-gallon fuel-card discounts lower the effective pump price, which scales directly with annual gallons. On a 25-vehicle Class 8 fleet at 60,000 miles/yr and 7 MPG, a 6¢/gal discount is roughly $13,000/yr of pre-fee savings. Net it against any monthly and per-transaction fees before crediting it to TCO.
