How to calculate your fuel cost per mile: A guide for car haulers

As a car hauler, understanding your fuel costs per mile is crucial for maintaining profitability. This guide will help you calculate your expenses accurately and make informed decisions about which loads to accept.

Why calculate fuel costs?

Fuel represents one of the largest operating expenses for car haulers. Without knowing your exact cost per mile, you might:

• Accept loads that barely break even or lose money
• Miss out on profitable opportunities
• Struggle to negotiate better rates with brokers
• Have difficulty planning for future expenses

How to calculate your fuel cost per mile

Basic formula

The basic formula for calculating fuel cost per mile is:

Fuel Cost Per Mile = (Fuel Price per Gallon) ÷ (Miles per Gallon)

For example, if diesel costs $4.50 per gallon and your truck gets 6.5 MPG: $4.50 ÷ 6.5 = $0.69 per mile

Understanding your results

When analyzing your fuel costs, consider these key metrics:

1. Total fuel cost

   • Calculate total gallons needed × price per gallon
   • Include both outbound and return trips
   • Factor in potential fuel price variations by region

2. Net revenue

   • Load pay minus total fuel cost
   • This gives you your earnings before other expenses

3. Profit per mile

   • Net revenue divided by total trip distance
   • Helps compare different load opportunities

4. Fuel cost percentage

   • What percentage of the load pay goes to fuel
   • Industry standard is typically 30-40%
   • Higher percentages may indicate unprofitable loads

Tips for reducing fuel costs

1. Maintain your equipment

   • Regular maintenance improves fuel efficiency
   • Keep tires properly inflated
   • Use aerodynamic accessories when possible

2. Plan your routes

   • Minimize deadhead miles
   • Plan fuel stops in cheaper areas
   • Consider traffic patterns and terrain

3. Drive efficiently

   • Maintain steady speeds
   • Reduce idle time
   • Use cruise control when appropriate

Setting your minimum rate

To set a profitable minimum rate per mile:

1. Calculate your fuel cost per mile
2. Add other operating costs (maintenance, insurance, etc.)
3. Include desired profit margin
4. Factor in potential deadhead miles

Example calculation:

• Fuel cost per mile: $0.69
• Operating costs per mile: $0.45
• Desired profit margin: $0.50
• Minimum rate needed: $1.64 per mile

Making informed decisions

With accurate fuel cost calculations, you can:

• Quickly evaluate load opportunities
• Negotiate better rates with brokers
• Plan more profitable routes
• Build a sustainable business

Real-world load calculation example

Let's analyze a typical car hauling load to see how fuel costs impact profitability:

Load details:

• Route: Atlanta, GA to Miami, FL (662 miles)
• Load pay: $1,800 (3 cars at $600 each)
• Return trip: Empty (662 miles)
• Total trip distance: 1,324 miles
• Current diesel price: $4.50/gallon
• Truck's fuel efficiency: 6.5 MPG

Calculation breakdown:

1. Total fuel needed

   • 1,324 miles ÷ 6.5 MPG = 203.7 gallons
   • Fuel cost: 203.7 gallons × $4.50 = $916.65

2. Operating expenses

   • Fuel cost: $916.65
   • Insurance per day: $40
   • Food/miscellaneous: $50
   • Total operating costs: $1,006.65

3. Profit analysis

   • Gross revenue: $1,800
   • Operating costs: $1,006.65
   • Net profit: $793.35
   • Profit per mile: $793.35 ÷ 1,324 = $0.60 per mile

4. Fuel cost percentage

   • $916.65 ÷ $1,800 = 50.9% of gross revenue

In this example, the fuel cost percentage is higher than the recommended 30-40%, suggesting that this load might need negotiation for a better rate or finding additional cars to haul on the same route to improve profitability.

Remember: Your actual costs may vary based on:

• Equipment type and condition
• Driving style and route conditions
• Regional fuel price variations
• Weather conditions
