His former club Atletico Madrid negotiated the unique clause in his contract on top of the £21million fee when he moved to Merseyside last summer.
Torres, 23, has already grabbed 18 goals in all competitions to trigger one bonus payment to Atletico.
Torres said: "I'm keeping everyone happy! Liverpool get the goals and Atletico get the money.
"I honestly did not think I would score as many goals as I have so soon. But things have gone well for me.
"Now I just want them to go better for the team in general so we can win the league or a cup to reward everyone's hard work."
