How This Calculator Works

  • Enter your fleet size and average per-vehicle monthly costs across fuel, maintenance, insurance, and tyres.
  • Enter an admin/overhead allowance as a percentage — typically 5–10%.
  • The calculator builds your total monthly and annual fleet budget, plus an average cost per vehicle.

Formula

Total Fleet Budget = (Fuel + Maintenance + Insurance + Tyres per Vehicle) × Fleet Size × (1 + Admin Overhead %)

The admin/overhead allowance covers compliance, licensing administration, and management time not captured in the direct per-vehicle costs.

Frequently Asked Questions

What should the admin/overhead percentage cover?

Compliance administration, licensing renewals, management and supervisory time, and other costs not tied directly to a single vehicle's fuel or maintenance spend.

Should driver wages be included?

This calculator focuses on vehicle operating costs. If you want a fully loaded budget including driver wages, add an additional monthly per-vehicle driver cost line to your own total separately.

How often should I recalculate this budget?

Quarterly is a reasonable minimum — fuel prices and maintenance costs both shift enough over a quarter to be worth reviewing against actuals.
