|Katie Holmes, Suri and Tom Cruise|
A source told TMZ.com Katie will receive $400,000 a year in child maintenance, equating to $33,333.33 a month.
He will be paying the support for the next 12 years until Suri is 18, totalling $4.8 million.
It has also been discovered both parties agreed that the tot would not attend a "residential" school - meaning she cannot be taken to an educational establishment with boarding.
Tom has also agreed to pay for all of Suri's expenses, including dental, medical, education and college costs.
Katie is believed to be a "new woman" since splitting from the 50-year-old actor, and is glad to be free of quasi-cult Scientology, to which Tom is devoted.
A source said: "She now gets to see her family more, feels free to concentrate on her career and is no longer living in fear of Scientology.
"Katie is a new woman, she feels refreshed, free of Tom and doesn't have a worry in the world."
