Broke by Choice

Being broke is expensive. Staying broke is a decision.

The Math

A year of driving, line by line

Ask what a car costs and almost everyone answers with gas. Gas is under a third of it. The rest never appears on a bank statement in a form you would recognise.

Ask someone what their car costs per month and you will get a number that is roughly the gas. It is a completely reasonable answer, because gas is the only part that involves standing somewhere watching a total go up. Everything else arrives annually, or once, or never as a payment at all.

So here is the whole thing, worked out with federal figures rather than estimates. The example is an eighteen-thousand-dollar used car kept eight years and sold for six thousand.

Assumptions behind this calculation

  • Inspection, interval in years: 1
  • Years kept: 8
  • Miles per year: 11,026
  • Excluding financing costs. If the car is on credit, interest comes on top.

The largest single line is depreciation, and it is the one that never appears as a payment. A car bought for eighteen thousand and sold eight years later for six has cost fifteen hundred dollars a year before it has moved a foot. You do not feel it monthly. You feel it once, on the day you sell, and by then it reads as bad luck rather than as the cost it was.

That is why the gas answer is so persistent. It is not ignorance. It is that gas is the only part of car ownership with a receipt.

Not necessarily sell the car. For a great many people in the United States a car is not a lifestyle choice, it is the condition of having a job, and an article that concludes otherwise is written for somewhere with trains. The useful outcome is smaller and more durable: you now know the real per-mile number, which means the next decision, a second car, a longer commute for more pay, a more expensive replacement, can be made with the whole figure instead of the gas.

Put your own numbers in

The calculator above starts from national averages. Yours will differ, and the two that move the total most are the purchase-minus-resale gap and the insurance. Both are on documents you already have.

Frequently asked

Does this include financing?

No. The calculation covers the cost of owning and running the car, not the cost of borrowing to buy it. If you have a loan, add the interest portion of your payments on top. That is deliberately separate, because a loan is a decision about money rather than about the car.

Why is inspection zero?

There is no U.S.-wide periodic inspection requirement, and where a state charges one the fee generally sits inside registration, which is already counted. Putting a number in both places would count it twice.
