Stripe Refund Fees
When you refund a transaction, the fees you paid to process the charge are also returned to you. That is, after charging and then completely refunding a payment, the net cost is zero. If you partially refund a charge, Stripe returns the pro-rated portion of the percentage cost—Stripe does not return the fixed fee (e.g., $0.30 in the US) in this case.To learn more about the processing fees on a refund, please visit: https://support.stripe.com/questions/how-do-i-issue-refunds
