There are many factors involved but the bottom line is: If you are signed up with only one or two paid surveys companies, you will never make enough money to QUIT your regular job once and for all. The possibilities really are endless though and depends on your on effort and time, just with any job really.

The price you are paid for any one survey can vary greatly between $3 to $75. Obviously you can't just do $75 surveys all the time, because they might only come up once or twice a month. So don'y neglect lower paid surveys, often they are much much shorter anyway. So for example, say it takes 1 and a half hours to complete one $75 survey and 10 minutes to complete a $5 survey; therefore you could complete nine $5 suverys in an hour and a half, which would make you $45. Not bad for 90 minutes of your time, eh? :-)

People who take this seriously generally earn in the region of $800 - $2000 a month (thats me included), and although I do know of a few people earning up to $3000 a month they work long hours at it.
