How much flexibility do you have? How many hours are you planning to work? If you can put in 30 hours per week and drive during high-demand periods, you’ll earn a reasonable salary in an urban area. But you’re correct that some areas just don’t have the demand to support a living wage for Uber drivers.
Just remember that you’re technically an independent contractor. Your wage is not your take-home pay. You have to pay for your fuel and cleaning costs, plus taxes. Most Uber drivers find that it takes a bit of experimentation to find the most lucrative driving schedule, so don’t be discouraged if you struggle when you start.
