QPR released accounts this week that showed their wage bill had doubled to £56million in the year to May 31, 2012. They have since strengthened further with a number of high-earning players brought to Loftus Road, including Loic Remy and Christopher Samba in January.
Relegation could have serious implications but Redknapp is convinced the owners know what they are doing, and said: "If the debts are high the chairman and the board must understand that. They're not silly men, they're successful businessmen. They know what they're doing so I'll leave it to them. It's their business."
He added: "It's important obviously (to stay up). But when you are a football manager we are not involved in that side of the business.
"I've said it a million times, we are not involved in players' wages. That's done at a different level to what we work. We work with the team and on the pitch. The financial side of it I don't know. Those results were from before I came here."
Redknapp's men meet a Sunderland side not yet out of trouble themselves on Saturday with the former Tottenham boss revealing the signings of Remy and Samba were driven by chairman Tony Fernandes.
"You don't keep going to them and saying you want to bring in this player or that player," added Redknapp.
"The chairman said to me in the window he wanted to make the two big signings. He did all the work in doing that. He brought the players to the club. I couldn't really take an awful lot of credit for those signings to be honest.
"He did that. He met the players and the agents. He did the deals and persuaded the players to come to QPR. It was great for the club. It's up to them.
"You couldn't get nicer people than the people that own QPR. I mean that genuinely. They're fantastic people."
