The credit card processing fee is 2.9% of the full order total, plus $0.30 per transaction. Because shipping and tax are included in that total, the fee will be slightly higher than 2.9% of your sale price alone. For example, for a $100 item with $7 shipping and $8 tax: the full order total is $115, the fee is $3.64 (2.9% × $115 + $0.30), and your payout is $96.36. Note: shipping and tax are paid by the buyer and are not part of your earnings — but because the credit card fee applies to the full transaction, a small portion of that fee is reflected in your payout.
