How to Calculate Cost Per Mile

Know Your Numbers Before You Hit the Road

If you're running a sprinter van business and don’t know your cost per mile, you’re flying blind. Whether you're hauling freight across states or doing local courier work, this one number determines whether you’re making money or just racking up miles and gas receipts.

Let’s break down how to calculate your true cost per mile, and why it matters.

What Is Cost Per Mile (CPM)?

Cost per mile is the total cost it takes for your van to travel one mile, including fixed and variable expenses. This number helps you set your rates, evaluate load offers, and stay profitable in the long run.

The Formula

Cost Per Mile = (Total Monthly Expenses ÷ Total Miles Driven)

To use this formula, you need to understand two types of expenses:

Fixed Expenses (Monthly Costs That Don’t Change With Miles)

These stay the same whether you drive 10 miles or 1,000:

• Van payment: $700
• Insurance: $450
• Phone + ELD/Data: $100
• Licensing + Permits: $50
• Parking/storage (if applicable): $100

Total Fixed = $1,400/month

Variable Expenses (Costs That Change With Mileage)

These go up the more you drive:

• Fuel: $0.25–$0.75 per mile (depends on fuel prices and MPG)
• Maintenance & tires: $0.10–$0.15 per mile
• Tolls: Depends on routes
• Load board fees or dispatch fees (if charged per mile or per load)

Let’s say you drive 5,000 miles/month and spend:

• Fuel: $1,000
• Maintenance: $300
• Tolls: $100
• Dispatch fees: $250

Total Variable = $1,650/month

Example: Calculating CPM

• Fixed Costs = $1,400
• Variable Costs = $1,650
• Total Costs = $3,050
• Total Miles Driven = 5,000

Cost per Mile = $3,050 ÷ 5,000 = $0.61 per mile

This means you need to charge at least $0.61 per mile just to break even — and ideally aim for $1.25–$2.00 per mile (or more) to make a real profit.

Why It Matters

Knowing your CPM helps you:

• Avoid underpricing your services
• Negotiate better rates with brokers and dispatchers
• Decide if a load is worth it
• Plan for slow seasons, repairs, or business growth

Tips to Lower Your Cost Per Mile

• Fuel at the cheapest stations using apps like Upside or GasBuddy
• Use routing software to reduce deadhead miles
• Stay up to date with preventative maintenance to avoid costly repairs
• Join fuel discount programs (e.g. Motive, Nastc, RTS)
• Consider a dispatch service that gets higher-paying loads

Cost per mile isn’t just a number, it’s your profit compass. Knowing it helps you move with intention instead of guessing. When you understand what it takes to keep your wheels turning, you can build a business that actually pays you back.
