The amount of money you can make doing data entry from home depends on the company who hires you for data entry.
My sister does data entry from home and earns $45.00 per hour which equals to $360.00 per day since she works 8 hours per day doing the data entry work.
She has a degree in medical coding and billing which is what you need to do data entry work since that's what most if not all data entry work is it's basically medical billing and coding.
