Seat reservation fees are set by the train companies. They depend on the country, the type of train and the class or type of seat or bed you choose.
Your first 4 seat reservations are free with your seat reservation credits. After that, you pay for any extra seat reservations yourself. How seat reservation credits work
Please note: a non-refundable booking fee of €2 per traveller per train applies to paid seat reservations.
