The cost of using the associate system is based on only transactions that have an associate payout amount related with it and it is 25% of the associate’s commission. For example, if an affiliate with a 20% fee rate sells a $100 product, then the affiliate is paid 20% of $100, or $20 for the sale. The fee you incur is 25% of the associate’s $20 fee, or $5. So for the $100 product, you are making $100 minus $20 paid to affiliate minus the $5 fee, or $75.
Note: this calculation doesn’t include the carrier fee for the order itself, as stated in your FastSpring User Agreement. Any questions about fees for using the system can be sent to .
