The U.S. national debt is closing in on $20 trillion. That’s $20-thousand billion. Or $20-million million. If you stacked up $20-trillion worth of thousand-dollar bills, it would supposedly reach something like 1,200 miles high. If you lived to be 80 years old, you’d have to spend about $700 million a day to run out of money.

Still having a hard time wrapping your brain around a figure that ridiculous? Well, Jeff Desjardins of the Visual Capitalist blog is here to help.

“The best way to understand these large numbers,” he said, “is to represent them visually, by plotting the data with comparable numbers that are easier to grasp.”

And that’s exactly what Desjardins did when he used the following five of visual comparisons and explanations to create one big infographic:

“The S&P 500 is a stock market index that tracks the value of the 500 largest U.S. companies by market capitalization. It includes giant companies like Apple AAPL, +1.57% , Exxon Mobil XOM, -2.47% , Microsoft MSFT, +2.40% , Alphabet GOOGL, +2.07% , Facebook FB, +2.66% , Johnson & Johnson JNJ, -0.61% and many others. In summer of 2016, the value of all of these 500 companies together added to $19.1 trillion – just short of the debt total.”

“The world’s largest money managers – companies like Blackrock, Vanguard, or Fidelity – manage trillions of investor assets in stocks, bonds, mutual funds, ETFs, and more. However, if we take the top seven of these companies and add all of their assets under management (AUM) together, it adds up to only $18.9 trillion.”

“Yes, countries such as Saudi Arabia, Kuwait, and Russia make a killing off of selling their oil around the world. However, the numbers behind these exports are paltry in comparison to the debt. For example, you’d need the Saudis to donate the next 146 years of revenue from their oil exports to fully pay down the debt.”

“Gold has symbolized money and wealth for a long time – but even the world’s annual production of roughly 3,000 tonnes (96 million oz) of the yellow metal barely puts a dent in the debt total. At market prices today, you’d need to somehow mine 155 years worth of gold at today’s rate to equal the debt.”

“That’s right, if you rounded up every single dollar, euro, yen, pound, yuan, and any other global physical currency note or coin in existence, it only amounts to a measly $5 trillion. Adding the world’s physical gold ($7.7 trillion), silver ($20 billion), and cryptocurrencies ($11 billion) on top of that, you get to a total of $12.73 trillion. That’s equal to about 65% of the U.S. national debt.”
