What is Fleet Running Cost?
Fleet running cost is the total annual expense of operating multiple commercial vehicles, covering fuel, insurance, maintenance, registration, depreciation, and fleet management overhead. Optimizing fleet costs directly impacts business profitability — a 10% reduction across 20 vehicles saves $15,000-$25,000/year. For individual vehicle analysis, see the Vehicle Cost Calculator.
The Formula
Total Annual Fleet Cost = Number of Vehicles × (Fuel + Insurance + Maintenance + Registration + Depreciation) per Vehicle
Worked Example
A fleet of 10 delivery vans: $5,500 fuel each, $2,400 insurance each, $1,200 maintenance each, $300 registration, $3,500 depreciation.
- Cost per van = $5,500 + $2,400 + $1,200 + $300 + $3,500 = $12,900
- Total fleet cost = 10 × $12,900 = $129,000
- Cost per van per month = $12,900 ÷ 12 = $1,075
📌 Total annual fleet cost: $129,000 for 10 vans — $1,075/van/month. Fuel accounts for 43% of the total, making it the primary optimization target.
Why This Matters
Fuel optimization
Fuel is the largest controllable fleet cost. Route optimization, driver training, and telematics can reduce fuel consumption by 10-20%. On a 10-van fleet spending $55,000/year on fuel, that's $5,500-$11,000 in savings.
Replacement cycle planning
Vehicles have an optimal replacement point where rising maintenance costs exceed depreciation savings. For vans, this is typically 4-6 years or 80,000-120,000 miles. Replacing too early or too late increases total fleet cost.
Common Mistakes
❌ Not tracking individual vehicle costs
Fleet averages hide problem vehicles. One van costing $4,500/year in maintenance drags up the average. Track costs per vehicle to identify which need replacing and which are performing well.
❌ Ignoring downtime costs
When a van is off the road for repairs, you lose revenue and may need a rental vehicle ($75-$150/day). Preventative maintenance costs $300-$600/year but prevents breakdowns that cost $800-$3,000 in combined repair and downtime.
