Depending on what company you use it's closer to fifty cents to a dollar per survey.
The two main ones I use are
Tellwut - They're good for simple member generated surveys that are 30 seconds each just doing them can get you $10 US a month or $15 Cad every 5 to 6 weeks but you have to complete a external survey every two weeks to keep full access to the member generated surveys.
Swagbucks - They fluctuate at how good they really are but just doing the bare minimum it is easy to get $3 to $5 a month but with some effort and depending on how often you complete surveys it is not hard to get over $50 a month.
You make less then minimum wage but just doing it every so often in your spare time is a good way to make some spare cash so you can keep your pay cheque to earn interest.
