MILLION POTTER PAYCHECK

the wiz kid
DANIEL RADCLIFFE
ACTOR Age: 17

• IN THE MONEY
July 23, Radcliffe's 18th birthday, will be a magic day for the star of the Harry Potter movies: He'll gain access to his $19 million investment fund—which he's socked away in a company jointly held with his parents Alan, a literary agent, and Marcia, a casting director. But with two more movies still to go—for which Radcliffe will be paid a reported total of $50 million—he can conjure up plenty more golden galleons where that came from. British newspapers have estimated that Radcliffe currently has a total net worth of $35 million or more, making him the U.K.'s richest teen.

• FIRST PAYCHECK
$320,000 at age 11 for the first two Potter films.

• BIGGEST SPLURGE
He recently dropped $17,000 on a custom-made Savoir mattress. But come his landmark birthday, "I don't think I'm going to do anything particularly exciting," says Radcliffe, an only child who lives with his parents in London. "People seem to expect me to splash out on a classic-car collection, but I've never been into cars or anything like that." He's more into cricket, theater (he shed his clothes for a recent turn in Equus in London), reading (lately Nabokov) and painter-sculptor Jim Hodges. "I know I'm lucky to be paid all this money to do what I love," he said in Britain's Daily Mail, but "[money is] not something that affects the way I think about things."

How do Harry Potter's COSTARS stack up?

EMMA WATSON
Age: 17
She will receive an estimated $5 million for each of the last two Potter films—meaning Watson (who has one younger brother) will have no problem following through on her plans to go to college. "Let's be honest: I have enough money never to have to work again, but I would never want that," she told Parade.

RUPERT GRINT
Age: 18
The actor who plays Ron Weasley also signed on for an estimated $5 million for each of the last two movies. The eldest of five siblings, he is enjoying every cent: "Recently I got an ice cream van," says Grint, who also has an all-terrain vehicle. "That's been really good fun. Usually I'm quite sensible with my [money]."

MILLION IN ENDORSEMENTS

the phenom
MICHELLE WIE
GOLFER Age: 17
She's only made $3,273 this year on the Ladies Professional Golf Association tour (blame a wrist injury), but Wie commands more than $10 million a year thanks to deals with Nike, Sony and Omega. For fun, the Stanford-bound only child shops for exotic earrings in her hometown of Honolulu: "I like going to the mall."

Who's the richest teen ROYAL?

PIERRE CASIRAGHI
HEIR Age: 19
He's tall, tan, and his family owns its own country: Monaco. Pierre Casiraghi, Princess Caroline's younger son, stands to eventually inherit upward of $260 million. (By comparison, Britain's teen princesses Beatrice and Eugenie's estimated worth is $5 million each.) While big sibs Andrea, 23, and Charlotte, 20, often grab the spotlight, Pierre, an economics student in Milan, "is the most extroverted" of the family, says an acquaintance. He plays the sax and has stepped out with some of Europe's most eligible aristocratic bachelorettes.

Hilary Duff
ACTRESS-SINGER
Age: 19

• IN THE MONEY
Her movie paychecks top $2 million, and she's sold 13 million albums worldwide. But as CEO of her own lifestyle company, she earns about $12 million a year, according to Forbes. Credit growing sales of her Stuff by Hilary Duff clothing line, jewelry and home decor for tweens, which is sold in stores such as Target and Wal-Mart. "It's so funny that people think that I'm a mogul," she says. "I definitely do know a lot about [running a business], but I have so many people that help me."

• BIGGEST SPLURGE
Watches, Marc Jacobs bags and "things for my house" in L.A. She and big sis Haylie, 22, also just indulged in a St. Bart's vacay.

• HOLD THE PORSCHE
"I definitely don't just buy what I want," she says. "My business manager says I'm well behaved." Case in point: Duff thought about buying a Porsche Cayenne Turbo for nearly $100,000, but her money man said, "You're a terrible driver. You don't need that kind of power."

• POWER MOVE
She's tackling the juniors market with a top-selling perfume (With Love ... Hilary Duff from Elizabeth Arden) and an upcoming fashion line.

• SPEND OR SAVE?
"Both, actually," says Rihanna, who has two younger brothers. "I don't like to waste money. I buy things that I'm going to get my money's worth out of, things I'm going to use a lot. I like to splurge on makeup and shoes—Louboutins! My mom loves bags. I bought her a Fendi."
