It's probably a safe bet to say that, financially speaking, the main stars of the Harry Potter film series are pretty much set for life. But how much are they actually worth? Don’t ask Rupert Grint, who played Ron Weasley in all eight films. He apparently couldn't even fathom a guess as to how much money he's got in the bank.

Last time we checked, Grint was the fifth wealthiest Harry Potter star, with a net worth of approximately $50 million. It's a hefty sum that puts him in line behind Daniel Radcliffe ($110 million), Robert Pattinson ($100 million), Emma Watson ($80 million), and Kenneth Branagh ($60 million). But in a recent interview with The Radio Times, Grint admitted that he doesn’t even know the ballpark of his net worth.

"I actually don't know how much I have," the 30-year-old actor said. "I couldn't even really guess. It doesn't really motivate me too much. It makes you comfortable, that's the good thing about it, I think."

"I'm glad it's there, but I'm not really that focused on it,” he added.

Since his Harry Potter days, Grint has gone on to appear in several TV series and films, and now stars in the TV adaptation of Snatch, based on the Guy Ritchie film of the same name. In late September, Grint revealed that he almost quit his role as Harry Potter's BFF following 2005's Harry Potter and the Goblet of Fire due to the stress of the series' popularity.

"It’s a big sacrifice," the actor told ​Independent. "You take for granted anonymity, just doing normal stuff, just going out. Everything was different and a little bit scary. There were times when I was like, 'I’m done.'" Though he certainly benefited financially from staying on, who knows if he even noticed.
