Refersion does not have a recommended commission rate, however here our some tips to help you decide on what number is right for you.  

 1) Take a look at the commission rates offered by competitors and similar companies in your industry. Try to stay competitive and offer a commission rate that is either the same or slightly above average for your product sector.

2) Understand your cost of goods sold and profit margins. If the margins on each one of your sales is high, it could be beneficial to offer a higher rate to affiliates in order to maximize revenues. 

3) Have a good sense of your customer acquisition costs through channels other than affiliates. Try to structure your affiliate rates based on those numbers.
