FAQ: Will my fees be prorated if I offer a partial refund?
Prorated final value fee credits for partial refunds effective May 23, 2022.
Starting May 23, 2022, when you issue a partial refund to a buyer, eBay will automatically credit a prorated portion of your final value fee based on the adjusted total amount of the sale.
In addition, eBay will automatically credit prorated portions of other applicable fees including Promoted Listings Standard and International Fees for global sellers. Other fees, such as the $0.30 per-order fee, Promoted Listings Express fee, and Promoted Listings Advanced fee, will not be refunded.
The credits will appear in your account starting May 23, 2022.
