IRS gives 14cents per mile for charitable causes (business is about 50 cents). I believe that it includes gas and wear/tear. But gas seems to cost about 10 cents/mile for a mid size car. Is it just 4 cents/mile for wear and tear? Without going into a detailed mathematical calculation, how can we …

@sciconf I use the 3 way split to guestimate. 1/3 each for fuel, depreciation, and maintenance/repairs. For 50 cents a mile on average that would work out to about 17 cents for gas, and the same for the upkeep. For an economy car the gas figure would be a lot lower, but the fed’s 14 cents is crazy…

That is not a bad estimate you outlined. You are assuming the car has zero value at 150k miles. That isn’t true. Its value depends on many many things. Lets assume its worth $3000 at 150K dropping your estimate to 21 cents/mile. It varies greatly on the car you choose, where you live, how you drive…

The deduction for medical travel is 23.5c/mile, and is supposed to be based on direct operating costs. The deduction for business use of car is 56c/mile and is based on ALL costs (except tolls and parking): depreciation, maintenance, repairs, fuel, insurance, etc. You also have the option of ta…

Actually I always used to figure about 7 cents for fuel and about 3 for maintenance. When I was cleaning my office I found the figures for my Olds where I did a complete cost per mile analysis. Can’t remember where I put it though. I believe the 14 cents though is just to cover the variable per m…

Actually I always used to figure about 7 cents for fuel and about 3 for maintenance. Dang! What do you drive? I always figured 25c/mile for the truck. Now that I got a few bucks together, I went and bought a small car (Cobalt), and I budget 15c/mile for it. (Recently lower…those prices are based on …

OK, you made me curious so I dug up my old figures. You’d have to adjust to todays dollars since this was on an 81 Olds diesel that I ran up to 480K. I think I did it because I was driving 100 miles a day or more and my wife was hounding me to get a new car instead of continuing to drive the old o…

@Bing My cost per mile includes maintenance, repairs and tires. That’s the way the AAA figures it as well. The 7 cents per mile or so in my case is based on 18 years and relatively low miles per year, which drives up the cost per mile. The USA average figures of $1100 per year based on 15,000 miles…

For repair and maintenance costs for a car 5 years or older I’ve always figured about $1000 per 10,000 miles driven, 10 cents per mile I guess.

@GeorgeSanJose Right, I include the first 5 years during which there are fewer repairs and replacements, which would lower the overall cost per mile. For my 1988 Caprice, the figure came to $11,900 over a 19 year (1988-2007) period and 138,000 miles, giving 8.6 cents per mile. As cars went, this wa…

Wear and tear of a car per mile?

Maintenance/Repairs

For what purpose?
For the purposes of tax deductions, it’s all defined anyway.
For academic purposes, wear & tear will actually vary wildly depending on driving environment. A ten year old car with 120,000 miles in Oklahoma has a very different “wear & tear profile” than a car with the same age & mileage in Boston… or NYC.
