A few issues with your calculation: 1. Drivers are not productive 100% of the time, 50% utilization is more common, so knock that hourly rate in half. 2. That’s revenue, not profit: you have to pay for gas, maintenance, depreciation, and probably higher insurance premiums for driving commercial and/or high mileage. The IRS deduction for business mileage for 2019 is 58 cents per mile, this is meant to be a median all-in cost, so subtract that from your fare, and subtract half again for the miles spent driving between fares or getting home after the last ride of the day.

For many drivers, you also need to factor in the car payment. Lots of Uber drivers bought their car specifically for Uber (and sometimes from Uber).
