Use the form below to measure cost per mile from fuel, maintenance, tires, repairs, insurance, depreciation, loans, and other overhead.
Example data table
This sample illustrates how different fleet groups can be compared after entering actual cost records and mileage totals.
| Fleet Group | Vehicles | Miles | Total Cost | Cost Per Mile |
|---|---|---|---|---|
| Sales Sedans | 8 | 96,000 | $38,640.00 | $0.40 |
| Service Vans | 6 | 84,000 | $43,260.00 | $0.51 |
| Executive Cars | 4 | 32,000 | $19,840.00 | $0.62 |
| Courier Hatchbacks | 10 | 150,000 | $56,250.00 | $0.38 |
Formula used
The calculator combines operating and ownership expenses, then divides total cost by total mileage to produce a reliable per-mile benchmark.
- Variable Cost = Fuel + Maintenance + Tires + Repairs + Tolls and Parking
- Fixed Cost = Insurance + Registration + Depreciation + Lease or Loan + Garage or Storage + Admin and Telematics
- Total Fleet Cost = Variable Cost + Fixed Cost + Other Fleet Costs
- Cost Per Mile = Total Fleet Cost ÷ Total Miles Traveled
- Cost Per Vehicle = Total Fleet Cost ÷ Fleet Size
- Miles Per Vehicle = Total Miles Traveled ÷ Fleet Size
- Monthly Cost = Total Fleet Cost ÷ Period Months
- Annualized Cost = Monthly Cost × 12

Frequently asked questions
1. What does cost per mile show?
It shows how much your fleet spends for every mile traveled. This helps compare vehicles, budgets, contracts, and route efficiency using one consistent performance measure.
2. Which costs should be included?
Include all meaningful fleet expenses for the period: fuel, maintenance, tires, repairs, insurance, registration, depreciation, financing, storage, tolls, telematics, and any other recurring fleet overhead.
3. Should driver wages be added?
Only add wages if your organization defines full delivery or service cost per mile. For pure vehicle ownership and operating cost, wages are usually tracked separately.
4. Why separate fixed and variable costs?
Separating them reveals whether mileage growth or ownership overhead drives spending. That makes planning, pricing, utilization reviews, and replacement decisions much easier.
5. How often should fleets calculate this?
Many fleets review cost per mile monthly, quarterly, and annually. Frequent checks help catch rising fuel use, repair patterns, or underused vehicles before costs escalate.
6. Can I compare different vehicle classes?
Yes. Compare sedans, vans, SUVs, and specialty units by calculating each group separately. Different duty cycles often produce very different cost-per-mile values.
7. What if one vehicle had major repairs?
That will increase the period result. Review both fleet-wide totals and subgroup results so unusual breakdowns do not hide normal operating performance trends.
8. Why annualize the result?
Annualizing converts short-period costs into a yearly estimate. It helps with budgeting, vendor discussions, replacement planning, and leadership reporting.
