It's hard to imagine what to do with that amount of money, but Gates knows how to make the most of it. While he has some indulgences like a Washington estate worth $125 million , a private airplane, and a luxury-car collection they make up only a fraction of his massive fortune.
He and wife, Melinda, previously said it's unfair they're so rich. Instead of spending billions on themselves, they often donate it to charity through the Bill and Melinda Gates Foundation. They've also pledged to give away most of their fortune through the Giving Pledge , which they launched in 2010.
See how Gates spends his billions.
Bill Gates, the cofounder of Microsoft, has an estimated net worth of about $95 billion, making him the worlds second-richest person.

If he spent $1 million a day, it would take him more than 245 years to spend his fortune. Heres how he spends his money.
Gates has invested in a variety of stocks and assets and launched a $1 billion investment fund, Breakthrough Energy, with 20 others.

Despite his massive fortune, Gates previously told Ellen DeGeneres that when he became a billionaire at age 31 (historys youngest billionaire at the time), he didnt go on a spending spree.
But he has indulged in things over time, he said, like a private plane.
Its been reported that Gates owns a Bombardier BD-700 Global Express, which costs $40 million and can seat up to 19 people.
Gates also spent a lot on his estate, Xanadu 2.0, in Medina, Washington. It took him seven years and $63 million to build. He purchased the lot for $2 million in 1988.
At 66,000 square feet, his home is worth about $125 million today.

In 2017, he paid $1,041,292.55 in property taxes on it, according to public filings.

The estate has a trampoline room, which Gates told DeGeneres his three kids love.
Theres roughly $80,000 worth of computer screens sitting around the house.
Devices worth $150,000 can display different paintings or photographs on the screens at a single touch.

However, there are real paintings on the wall as well like the Winslow Homer painting Gates purchased for $36 million in 1988.

Theres also a 60-foot pool in its own separate, 3,900 square-foot building.
Thats not to mention the 2,100-square-foot library, home to a 16th-century Leonardo da Vinci manuscript that Gates bought at auction for $30 million in 1994.
Gates reportedly pays to have sand imported from St. Lucia in the Caribbean to the shore surrounding his house.
In addition to a home theater for 20 guests, six kitchens, and 24 bathrooms, Gates house has various garages for 23 cars.
Its perfect for Gates, an avid luxury-car collector. His first big splurge after founding Microsoft was a Porsche 911 supercar, he told DeGeneres. He later sold it, and it was auctioned for $80,000.
But that wasnt Gates last Porsche. He also has a Porsche 959 in his car collection.
Outside of his Washington pad, Gates also has a 4.5-acre vacation ranch in Wellington, Florida, with a 12,864-square-foot mansion.
He reportedly dropped $27 million to buy a whole string of properties in the area.
The area is hotspot for wealthy equestrians. His daughter Jennifer is an accomplished equestrian, and he bought the property to support her passion.
In California, he owns the 228-acre Rancho Paseana, which he purchased for $18 million. It includes a racetrack, orchard, and five barns.

He also reportedly purchased a 492-acre Wyoming ranch, which listed for $8.9 million back in 2009.
But Gates real-estate portfolio doesnt end there.

In 2013, Gates and several unnamed buyers paid $161 million for the Ritz-Carlton in San Francisco. As of 2014, it was reportedly worth $200 million.
When hes not busy buying real estate or working, Gates needs a vacation or two to unwind.
Hes traveled to Australia and Croatia....
....and Belize and the Amazon in Brazil.
Hes also treated his family to a Mediterranean vacation on board the 439-foot superyacht Serene, which he chartered for $5 million a week. It included a helicopter.
He previously said that he likes to play tennis and go skiing. Hes also been spotted spectating at tennis matches.
But Gates downtime isnt always so adventurous. Hes an avid reader, having indulged in quite the book collection.
Hes also an "avid bridge player," as he once told Reddit.
Gates hates to shop for himself, but did admit that he likes to "buy nice things" for his wife, Melinda.

But Gates splurges are only a fraction of his massive fortune. He previously told The Telegraph, "I have no use for money." Instead, he often donates to or invests his money in good causes.

Gates agreed to give away most of his fortune through the Giving Pledge, which he launched in 2010.
The Gateses spent money traveling to Tanzania and other countries for charity work.
In 2017, they donated $4.78 billion, mostly to projects run by the Bill and Melinda Gates Foundation.
They donated more than $2 billion in 2016 to causes related to global health and development and US education.
Theyve pledged about $2 billion to defeat malaria, donated more than $50 million to fight Ebola, and pledged $38 million to a Japanese pharmaceutical company working to create a low-cost polio vaccine.
The Gates Foundation has also committed at least $2.5 billion to the GAVI Alliance, which works to improve access to vaccines in poor countries.
Bill and Melinda also prioritize education. The Gates Foundation established the Gates Millennium Scholars Program, which has received $1.6 billion.

It also partnered with the Dangote Foundation in 2016 to spend $100 million on eliminating malnutrition in Nigeria.
