Dear datendelphin, thank you very much for your answer!

Yes, PayPal shows the exchange rate.
I tried a donation with £15 on PayPal to see what the exchange rate is. (This should be the same as if I would pay the membership fee!?)
I would have to pay 17,57€ what is actually £15,60 according to the current exchange rate, so I have to pay 0,68€ more to PayPal because of the currency exchange.
OSMF must pay to PayPal again.
Could you please tell me what exactly OSMF has to pay to PayPal, because I don’t know which fees count for OSMF? (For an Associate member who has fully paid in euro by PayPal balance or bank account from Germany.)
Do you have to pay (in this case) 2% (https://www.paypal.com/uk/webapps/mpp/cross-border-and-conversion-fees#currencyconversion)?
Please excuse me, for me the documentation of PayPal is confusing and complicated. :roll_eyes:

According to Regulation No 924/2009 bank charges of SEPA transfers in every SEPA country must be treated same as a normal transfer.

See https://www.ecb.europa.eu/paym/retpaym/undpaym/legasp/html/index.en.html:

Even though some banks charge fees for national transfers, at my bank this is (still) free of charge. This means that a SEPA transfer does not cost me anything, in contrast to the very expensive International bank transfers.

No, the meaning of the SEPA transfer is, that it can only be processed in Euro, which means that no currency exchange fees accrue!

see https://www.ecb.europa.eu/paym/retpaym/undpaym/qa/html/index.en.html:

That are the reasons why I want to pay with SEPA.
First I don’t have to pay bank (transfer) charges,
furthermore no exchange fees (no exchange-related losses),
moreover OSMF doesn’t have to pay bank transfer charges because of SEPA (depends on your bank, so I still don’t know).
And the euro is currently the more stable currency, also with regard to the BREXIT.

I hope that my citation method is correct.

Thanks you in advance!
Kind regards
