Maintenance cost per mile(CPM)

Track this by vehicle class and age band; the trend against your own prior periods matters more than any single value.

Total maintenance spend over fleet miles — the budgeting and replace-vs-keep number.

  • Maintenance CPM only — fuel, insurance, depreciation, driver wages and admin live in the full cost-per-mile stack (see the fleet fuel cost calculator for the fuel leg).
  • Compare like with like: split CPM by vehicle class and age band before drawing conclusions; mixing a new van fleet with old class-8 tractors makes the number meaningless.
  • Published industry surveys of class-8 carriers have run repair & maintenance roughly in the $0.15-0.25/mi range in recent years; light-duty fleets differ substantially — treat any external benchmark as context, not a target.
  • Rising CPM with age is the replace-vs-keep signal: chart this number against vehicle age and the crossover with replacement cost identifies the cycle point.
