How It Works
Fuel is the largest single operating expense for truck drivers, typically accounting for 30-40% of total operating costs. Creating an accurate fuel budget helps owner-operators set aside enough cash, price loads profitably, and avoid cash flow crunches. A good fuel budget also helps you evaluate whether fuel discount programs and cards are worth their fees.
The Formula
Variables
- Monthly Miles — Total miles you plan to drive per month
- MPG — Your truck's average fuel efficiency
- Fuel Price — Expected average diesel price per gallon
Worked Example
At 10,000 miles per month, 6.5 MPG, and $3.85/gallon diesel, you need about 1,538 gallons monthly. That costs $5,923 per month, $17,769 per quarter, and $71,077 per year. This means you need to earn at least $0.59 per mile just to cover fuel before any other expenses.
Practical Tips
- Add a 10% buffer to your fuel budget to account for price spikes, detours, and idling time.
- Track actual fuel spending weekly against your budget to catch overruns early.
- Consider seasonal fuel price patterns — diesel tends to be more expensive in winter due to heating oil demand.
- Use fuel discount programs like Mudflap, TCS Fuel Card, or fleet cards to save $0.10-$0.40 per gallon.
- Budget fuel as a percentage of gross revenue — if fuel exceeds 35% of revenue, you need to raise rates or improve efficiency.
Frequently Asked Questions
How much does the average owner-operator spend on fuel per year?
At current diesel prices and average mileage (100,000-120,000 miles/year), most owner-operators spend $55,000-$75,000 per year on fuel. This is typically 30-40% of their total operating cost.
Should I budget for fuel price increases?
Yes. Plan your budget at 5-10% above current prices to create a safety margin. If fuel prices drop, the savings become profit. If they rise, you are protected from cash flow problems.
How do fuel cards help with budgeting?
Fleet fuel cards provide detailed transaction reports by date, location, and amount. This data makes tracking spending against budget much easier. Many cards also offer per-gallon discounts of $0.05-$0.25.
How many gallons does a semi truck use per month?
At 10,000 miles/month and 6.5 MPG, a semi truck uses about 1,538 gallons per month. Heavy haulers or trucks in mountainous terrain may use 1,800-2,000+ gallons monthly.
What percentage of revenue should go to fuel?
Industry benchmarks suggest fuel should be 25-35% of gross revenue for a profitable operation. If fuel costs exceed 35% of revenue consistently, your rates are too low or your fuel efficiency needs improvement.
