How can you discount wear & tear on a car. If you keep your car in the garage, it can last decades. But if you drive the car, realistically, you get about 100,000 miles out of it, after which it is essentially a clunker. If you have a moderately priced car suitable for Uber, it is costing about $25,000. That is 25 cents per mile at 100,000 miles. But as an Uber driver, you aren't driving a car that is pushing 100K miles. More likely, you sell the car at 40,000 miles for $10,000. So that car cost you 37.5 cents per mile. And that doesn't include any maintenance.
Then you add gas. According to Gas Buddy, the cheapest gas in the New Brunswick area is $1.50 per gallon. So assuming you are getting 25 mpg (pretty decent for stop and go driving), that's another 6 cents per gallon.
So even with the Uber model that you have the asset, and aren't paying depreciation or insurance, you still have a cost of about 44 cents per mile just for wear & tear and gas.
