Individual silver medal = €22.500
Individual bronze medal = €15.000
As for team medals, there is a formula to decide how much every athlete gets: basically the prize money for the equivalent individual result multiplied by the root of the number of participants in the team...the result of that calculation is then divided by the number of participants. An example is the men's fours in rowing, who won gold and will each receive €15.000 per athlete.
In large teams, like field hockey, there is a minimum prize to avoid this formula leading to too small prizes. The minimum is €11.000 per athlete for gold, €8.000 for silver and €5.000 for bronze.
And it's the Netherlands, so we gotta keep it as cheap as possible. Medals are not accumulated normally, a second medal leads to another formula: two thirds of the money it would be worth in case it was someone's first medal. A third medal is worth one third of the first medal's worth. For example three golds doesn't mean three times 30k, it means 30k plus 20k plus 10k = 60k.
And, again, it's the Netherlands: it is specifically mentioned that the prize money is definitely not tax free. So probably around half of it goes out the window immediately. Which is so goddamn annoying, just pay out more and let whatever remains after tax be the official number, so nobody gets 'cheated'.
