Cost Per Mile Calculator
You know the car costs money. This tells you how much per mile. Add a year of expenses, enter the miles you drive, and get the one number that makes every trip easy to price.
What each mile really costs you
Add up a year of fuel, insurance, maintenance, and anything else, then divide by the miles you drive. It's the number that turns a commute into a dollar figure.

Why the number lands where it does
The recipe is simple: total up everything you spend on the car in a year, then divide by the miles you cover. Fuel, insurance, and maintenance do most of the heavy lifting, with the other bucket catching whatever's left.
Here's the part people miss — insurance is mostly fixed. Whether you drive 5,000 miles or 20,000, that premium barely moves. So the more you drive, the thinner it spreads and the lower your per-mile cost goes. A $5,000-a-year commuter often pays more per mile than someone doing 15,000.
Run it once and you'll never guess at a road trip's cost again. Multiply your per-mile figure by the distance and you've got the driving cost, gas and wear and all.
Frequently asked questions
What counts as an "other" yearly cost?
Anything you spend to keep the car on the road that isn't fuel, insurance, or routine maintenance. Registration, parking, tolls, a share of your loan interest, tires — drop it all in the other bucket so nothing gets missed.
Should I include my car payment?
That's your call. If you want the full cost of driving, add the yearly interest portion of your loan to the other-costs field. Many people leave the principal out since that's buying the car, not running it.
Why does cost per mile matter?
It turns a fuzzy sense of "cars are expensive" into one number you can act on. At 55 cents a mile, a 30-mile round-trip commute is about $16 a day, which reframes whether that job across town is really worth it.
How do I lower my cost per mile?
Two levers: spend less or drive more. Shopping insurance and staying on top of maintenance cut the top of the fraction. Driving more miles spreads fixed costs like insurance thinner, which is why high-mileage drivers often have a lower per-mile figure.
Is this the same as the IRS mileage rate?
Not exactly. The IRS rate is a flat national average for tax purposes. This gives you your real number based on your car and your driving, which can land well above or below the IRS figure.
What's a typical cost per mile?
For an average car driven 12,000 miles a year, all-in costs often land somewhere around 40 to 70 cents a mile once fuel, insurance, and upkeep are counted. Bigger vehicles and low mileage push it higher.
