Is it then not fair for the question to be, did I make enough money to replace the car and then make some as well?
So why is the calculus here need to me any more complicated than am I spending less over all than what I am being paid?
I seem to be missing the point of how making $1,000/month and spending about $300 at best is not viewed with a similar positive viewpoint?
If i make even 1 cent of profit does that not mean that this is a money making effort?
It appears others see it differently, though my question is still if you are not seeing it as a losing proposition why is it a bad idea?
You are the ideal candidate for a food delivery job.
You ignore both the costs incurred AND how many hours you spent to earn the money.
All you care about is generating enough revenue to exceed your (unknown) costs, regardless of how many hours it takes to do so.
Just because something isn't a "losing proposition" doesn't make it a good idea.
If you kept an accurate accounting of all your expenses and hours worked, and found you were making minimum wage with this side hustle, would you think this was a good idea or a bad idea?
If I was to work fast food would everyone be worried about the wear and tear on my car? Of course not, because driving to work is assumed to be part of having a job.
A car isn't a requirement for working at a fast food restaurant. They can walk, ride a bike/bus, catch a ride, or drive a short distance.
They aren't required rack up 20K unreimbursed miles in their own vehicle as a condition of their employment.
The average fast food worker (if they even have their own car) is likely only driving a few miles to work. Say 1.5K miles/year, not 20K miles/year.
If someone gets a job at a fast food restaurant 80 miles away from their house, then yes you would absolutely be worried about the wear and tear on the car.
Here I have some fraction of 57.5 cents of expense for every mile. We can again get into minutiae about how much that really is. Is it 9 cents of 20? I am spending a fraction of that expense but get to claim 100% of the mileage expense.
You still aren't getting it, even though it's been pointed out by multiple people.
You may be spending a fraction of the 57.5 cents/mile, but you are also getting only a fraction of that 57.5 cents as an actual financial benefit on your taxes.
The challenge here is the rabbit hole this can go down to try to figure out the costs is always prone to now being accurate. I use the car outside of food delivery. When my water pump fails was it really because of the delivery, or would it have failed anyway just owning the car and making no money with it? If I only deliver on sunny days does that mean i can ignore wiper costs because those only happen on the personal time? You can see what I am getting at about how this seem to me to be an exercise in minutiae.
You know it is not this complicated.
All you need to do is allocate vehicle expenses based on the proportion of total miles spent on delivery. For examples...
Total Miles - 30,000
Personal Miles - 10,000 (33%)
Delivery Miles - 20,000 (67%)
Take all of your expenses during this time, say $1500 for oil changes, tires, brakes, battery, ect.
That means $1000 of this cost is allocated as delivery expenses.
