How much you have to pay for yellow card in soccer?

Answer 1

The FIFA Laws of the Game don't list a fine. Each league sets its own rules for such things, so players in some professional leagues might have to pay a fine if shown a yellow card, but that would be decided by their specific league.

Answer 2

if you mean a yellow card in football, it means a warning, 2 of them and a red card is issued and throws you out of the game and the next one.
