In the first year of a three-year contract with the Golden State Warriors, which will make him roughly $42 million, the hardworking centre earns more each season than an entire AFL or NRL team.

Given the fact that he’s spent his entire adult life in the United States among high-flying millionaire athletes, you could excuse Bogut for being a little carefree with his spending.

But a sneak peek at his expenses over a five-day period — which Bogut kept for ESPN The Magazine’s Big Money Issue — reveals the Melbourne-born hoops star is (usually) anything but.

Bogut admits he does have one guilty pleasure — his car collection.

The seven-footer has 16 muscle cars, including a prized 1969 Ford Mustang Boss 429 which can sell for upwards of $400,000.

He’s also recently purchased a new home in Walnut Creek, California — paying cash — but outside of that his weekly expenses, which you can read in detail below, don’t contain much excess.

“I’m probably the complete opposite of what you think an NBA player is,” Bogut says.

“I don’t like to do anything extravagant. I like everything to be of a nice quality, but I refuse to be stupid. I don’t spend on material things, really. I like to have a cash surplus at all times, and right now I’m saving for different investments.”

Bogut studied for a finance degree externally through an Australian university, for two semesters, to get a handle on how to manage his money.

“I don’t have someone advising me financially, I do it all myself, I pay all my bills, I know where all my money is,” Bogut says.

“I think that’s the point you want to get to towards the end of your career, so when you transition to retirement you know how to pay a light bill, you know how to get money out of a bank. They’re very important life skills to have.”

$4.45: Frappuccino, Starbucks

$38.97: Two chicken salads, two iced teas, one soup, Tender Greens
