Cost per mile calculator

Worksheet

Your vehicle costs over your own miles — carried to thousandths of a cent.

The miles are yours, off your own odometer

There is no tracking, no location data and no integration with anything in a vehicle. You give the period and the miles it ran, and the sheet divides. If the mileage box is empty it refuses to divide rather than printing the total as a rate.

What to count is your call

Fuel, tires, insurance, registration, repairs, the payment — the sheet does not have a list of what belongs and what does not, because a business that owns its trucks and one that finances them are counting different things. Write what you included in the notes so the figure means something next year.

No rate is supplied anywhere

No federal mileage rate, no fuel price, no depreciation schedule and no tax treatment. Every number on the page is one you typed off a bill or an odometer.

Alongside this: Mileage & fuel log · Fuel card · Lease or buy

A worksheet that does arithmetic on figures you entered. CompliMaint publishes no mileage rate, computes no depreciation, determines no tax deduction, performs no IFTA or fuel tax apportionment, and gives no tax or accounting advice. Everything runs on your device.

Questions people ask

Why not use the federal mileage rate?
Because that is a tax figure with a specific purpose, and it is not what your truck costs to run. This tool holds no IRS or federal rate and never will. What you actually spent, over the miles you actually drove, is a different and more useful number.
Does it calculate depreciation?
No. Depreciation is an accounting and tax treatment that depends on how the vehicle was bought, how it is held and what your accountant elects. If a payment or a purchase cost belongs in your comparison, enter it as a cost line and say so in the notes.
Can I use this for a tax deduction?
Not as it stands. It is a record of what a vehicle cost you to run, not a tax calculation, and nothing on it should go on a return without your own advisor looking at it. It computes no deduction and applies no rate.
Does it do IFTA or fuel tax apportionment?
No. There is no jurisdictional apportionment, no fuel tax calculation and no reporting of any kind. Those are regulated filings with their own requirements.
Why thousandths of a cent?
Because a real per-mile figure is often under a cent per unit and rounding it to whole cents changes the answer. 58.5 cents a mile becomes 58 or 59, which is a one-to-two percent error on every mile of every job for a year.
