"I've got guys in the team who are older than me, and more experienced than me, and I'm nobody's financial adviser," said the captain.
But how should his team handle the pressure of playing for such a big prize?
"The key is not to think that in three hours' work you can earn 'x' amount of money," said Pietersen.
"The key is to realise that if you keep putting in the performances for England, day in and day out, you are going to earn much more than that. So what's the point in worrying about three hours? I'm certainly not. I couldn't give two hoots about it, but I'm probably in a different position to some of those players."
England play Middlesex on Sunday and Trinidad & Tobago on the following Tuesday as part of their warm-up.
