Spend a Billion Dollars is a free online shopping spree simulator that gives you $1,000,000,000 to spend however you want. Buy everything from Big Macs and sneakers to superyachts, skyscrapers, and private islands. With over 25 items across 5 categories, the game reveals just how incomprehensibly large a billion dollars really is. Most people struggle to spend even half.
Browse through categories of items ranging from everyday purchases to mega-scale acquisitions. Use the +/- buttons to buy or sell items, and for cheaper items, use bulk buy buttons (+10, +100, +1000) to speed things up. Your remaining balance updates in real time with smooth animations. When you're done shopping, view your receipt to see a full breakdown of your spending, including fun statistics about how much of your billion you managed to blow through.
If you spent $1,000 every single day, it would take you over 2,739 years to spend a billion dollars. Even spending $10,000 per day, it would take 274 years. This simulator lets you try spending it all at once and see just how impossibly large a billion dollars really is.
With a billion dollars, you could buy roughly 167 million Big Macs, 2,380 average US houses, 2,000 Lamborghinis, 6 superyachts, or nearly 3 private islands. Even buying all of these, you might still have money left over. A billion dollars is an almost incomprehensible amount of wealth.
A billion dollars is 1,000 times more than a million dollars. If a million dollars were a single step, a billion dollars would be a 1,000-step journey. In time terms, a million seconds is about 11.5 days, while a billion seconds is nearly 31.7 years.
