Most of the costs of a car are fixed once you own it. Wear and tears per mile is actually small. Insurance is the same for a car driven 7000 miles a year as one driven 30,000. there is a small discount for less than 7000 miles/year, but it is still fixed. Likewise the car payment doesn't change at all. The IRS has to come up with a fair number that translates all those fixed costs into per/mile. It is a good financia…
Not really. Buying new tires are a thing. Even if you buy cheap tires and get good life out of them (and that combo is...rare, you get what you pay for), that's, say, $400 ever 40,000 miles, that's a cent a mile right there..and tires are usually more expensive than that and don't last that long. The most obvious cost of wear and tear though is that eventually the car needs to be replaced. More miles = sooner replace…
It depends on the car, but typically you are looking at $.20/mile for fuel, and $.05 for all other maintenance (including tires).
The average new car payment is something like $550/month. The average used car is somewhat less of course. Most people are making payments. Insurance is $500/year if you have a perfect driving record, many people pay more. These costs have nothing to do with how far you drive.
A few years ago I calculated my actual per/mile cost for my car, it was $.15/month, even though I bought it new (I track every fill up, though at 46mpg my fuel costs are less than average). The car had 200,000 miles on it to spread all the fixed costs across, and had been paid off for a few years.
The point is the marginal cost to drive a car you already own is low.
