Truck Operating Cost Calculator
Your work truck costs money every mile it turns — fuel, insurance, tires, the payment, and the value it quietly loses to age. Most owners never total it, so the truck eats profit off an entire route without anyone noticing. Enter your numbers to see the true cost per mile, per month, and per job's drive. Works for any van or work vehicle, not just a truck.
The vehicle
Every mile has a price — and it's more than fuel
Ask a busy tradesperson what their truck costs and most will name the gas. Fuel is the visible cost, but it's often less than a third of the real number. Insurance renews whether the truck moves or not. Tires wear out on a schedule. The loan or lease payment leaves your account every month. And the quietest cost of all is depreciation — the value the truck sheds just by getting older and racking up miles, a real loss even though no invoice ever arrives for it. Total all of that and divide by the miles you actually drive for work, and you get the number that matters: your true cost per mile.
For a financed work truck that number commonly lands around a dollar a mile — often well above the IRS standard mileage rate, because that federal figure is a national average built for a typical car and blends away the payment and depreciation that make a work truck expensive. This is why cost per mile is worth calculating for your specific vehicle instead of borrowing a rule of thumb. A paid-off, fuel-efficient van might run 50 cents a mile; a big financed diesel that guzzles fuel and sheds value fast can push past $1.50. Only your own numbers tell you which truck you're driving.
Once you have the figure, driving stops being invisible. A route with an hour of windshield time between stops isn't free — at a dollar a mile, sixty miles of driving is sixty dollars gone before the first job of the day earns anything. That's why tight routing, closer jobs, and recovering mileage on distant work aren't fussy details; they're the difference between a truck that carries your business and one that quietly eats a route's whole profit. The trip tool below turns any job's drive into a number you can put on the invoice.
Two worked examples
Financed work truck. 15,000 business miles a year at 18 MPG with $3.50 fuel is about $2,917 in gas. Add insurance $1,800, maintenance $1,500, tires $400, registration $200, a $450 monthly payment ($5,400 a year), and $3,000 of depreciation. Total: roughly $15,217 a year, or about $1,268 a month. Divide by 15,000 miles and the true cost is $1.01 per mile. The payment and depreciation alone are more than half of it — which is exactly why "it's just gas money" undercounts a financed truck so badly.
Costing a job's drive. A job 20 miles away is a 40-mile round trip. At $1.01 a mile, that drive costs about $40.58 before any work happens. To cover it with a 20% margin you'd want to bill roughly $50 in trip or mileage charges. Skip that on a handful of distant jobs a week and you've handed back several hundred dollars a month in vehicle cost you never recovered — the leak most owners can't find because it never shows up as a single bill.
Four ways the number comes in too low
Counting only fuel. Gas is the visible third of the cost. Insurance, tires, the payment, and depreciation are the rest — leave them out and your cost per mile is a fraction of the truth.
Skipping depreciation. No bill arrives for it, so it's easy to ignore — but the truck really is worth less every year, and that lost value is a genuine cost of driving it. Estimate it as purchase price divided by the years you'll keep the vehicle.
Trusting the IRS rate as your cost. The federal mileage rate is a national average for a typical car, useful for taxes, not for pricing. A financed work truck usually costs more per mile — price off your own total, not the government's.
Not recovering distant-job driving. If a job is far, the drive has a real cost that flat pricing ignores. Add a trip or mileage charge on distant work, or watch those jobs quietly run at a loss.
Frequently Asked Questions
How do I calculate the cost per mile to run a work truck?
Total every yearly cost — fuel, insurance, maintenance, tires, registration, payment, depreciation — and divide by your business miles per year. About $15,000 over 15,000 miles is ~$1.00/mile.
Why is my real cost per mile higher than the IRS mileage rate?
The IRS rate is a national average for a typical car. A financed work truck's payment and depreciation push its real per-mile cost above that average.
Should I include depreciation and my truck payment?
Yes. Both are real money the truck costs you. Leaving them out is the most common reason this number comes in too low.
How does cost per mile help me price jobs?
It makes driving billable. At $1/mile, a job 20 miles out has $40 of round-trip vehicle cost before you start. The trip tool shows what to charge to cover it.
