Should I include depreciation?

If you want “true” CPM, include depreciation. If you want operational CPM for coaching, track both: operational CPM (fuel + maintenance + downtime) and all-in CPM (adds depreciation + insurance).

What if miles vary a lot month-to-month?

Use a 3-month rolling average for miles and costs. CPM becomes more stable and useful.

How do I lower CPM fastest?

Common levers include reducing idle time, improving driver behavior, tightening preventive maintenance, and reducing downtime through quicker repairs and better scheduling.

What is cost per mile for a fleet?

Cost per mile ($/mile) is a single KPI that combines operating expenses like fuel, maintenance, tires, insurance, depreciation, downtime, and overhead divided by miles driven.

How do you calculate fleet cost per mile?

Add your costs for a chosen period (month/quarter/year), then divide by total miles driven in that same period. You can calculate both variable and fixed components.

Can I export my results?

Yes. This calculator exports a breakdown and totals to CSV and can be printed.
