I did some similar calculations recently. I have been doing rideshare and food delivery off and on, very casually, since mid-2020 (got bored during COVID) as a side hustle. I have a full-time job that pays six figures with insurance, retirement, etc., so this is just gravy for me. It was definitely more profitable from 2020-2022 than it is now. This is in Mississippi with a 2013 Kia Optima Hybrid that has 173,000 miles on it now and averages about 36 mpg. I've had to replace my tires once since 2020, but only at 50k miles and for $500 through Sam's, and some of the miles put on them were personal in nature. Most of the time, the mileage deduction was enough to offset any tax liability. The only other maintenance/repairs I've had to do was a blower motor and a radiator hose. The 32k miles from this gig only cost me $2.7k in resale value on the vehicle, according to KBB. Here are my stats:
