Just like with normal payments, for Recurring you only pay the transaction costs for a successful payment. Recurring payments are only possible via credit card and SEPA direct debit. The standard rates for these payment methods are as follows:

SEPA direct debit: €0,25 per transaction

Credit card (per transaction): 

Type of credit card transaction Rate per transaction
Visa or MasterCard EU consumer cards + Postepay + Cartes Bancaires 1.8% + €0.25
Visa or MasterCard commercial and non-EU cards + American Express 2.8% + €0.25
Maestro €0.39

The use of the Recurring option and the APIs is free of charge.

Any reversals and chargebacks from consumers can cause unnecessary costs. Don’t take any risks and clearly communicate in advance which amounts will be charged at which times.
