Questions

How is cost per mile calculated?

Your total monthly costs divided by the miles you drive in a month. If you drive 1,000 miles and spend $830, that's 83 cents a mile.

What should I include?

Everything you pay to keep the car on the road: fuel or charging, insurance, the car payment or lease, maintenance and repairs, and other costs like parking, tolls and registration.

Does it include depreciation?

No, not unless you add it. Depreciation is the value your car loses each year. To include it, estimate the yearly loss, divide by 12 and add it under Other expenses.

Is it accurate?

It's only as accurate as the numbers you enter. Averages over several months work better than a single month. To get your real numbers, log your costs as they happen in Milebook.
