I'm trying to figure out how much it costs me to use my car for ride sharing. I have a 2017 Honda CR-V LX. I put about 5000 miles a year on it myself, not sure how many I will put on it for ride sharing. Maybe 1000 miles a month. Any idea how to figure this? My car is paid off and insurance is about $60 a month. It's still under warranty so I don't have much maintenance to pay for yet.
