I made the below poll because many new translators applying to my translation agency were asking what they should charge. I drew the rates data from my database of more than 15,000 translators who had already applied (until Sept. 4 2014), the remaining data submitted to this poll directly from this website (since May of 2009).
Note that rates charged to direct customers are generally higher than fees charged to translation companies. The % is a wild card, so chin% would yield both “chinese mandarin” and “chinese traditional”.
Here is some more info and tips on translator fees, charges and rates in general (where this poll was originally posted), as well links to other sites that offer similar information.
Here you may add your own rate to the poll.
