Here's the math since I was curious

1492 was 194,440 days ago * $5000 = $972,200,000

Forbes put bezos at $209,000,000,000 for 2025

The author of the tweet didn't go far enough. Should have gone for for 1 million USD instead. Even if you made 1 000 000$ every day, it would still not be enough.

Absolutely insane.

shit, I was about to write that you overshot by a few zeroes, and then I looked closer and put the commas and everything, and you're right: 194,440,000,000.

[–] [email protected] 8 points 1 day ago

Yeah, it's so fucking wild.

[–] [email protected] 10 points 1 day ago (1 children)

Well it says that you wouldn't even be a billionaire. That's right up against the limit for being a billionaire.

But yeah bezos has over 200x that money

[–] [email protected] 0 points 1 day ago

No, Bezos has basically the same amount of money. Still absolutely wild.

I feel like compound interest would be important here

[–] [email protected] 34 points 1 day ago (2 children)

It cracks me up that compound interest gets raised every time someone makes an argument about just how much money billionaires have. As if the only reason we're not billionaires is because we were too dumb to invest the $5,000 we've been making every day since Columbus sailed the ocean blue.

[–] [email protected] 2 points 1 day ago

No it isn't because it's an imagery used to show how absurd that amount of money is. 5000 a day is easy to grasp and a few hundred years is easy to grasp.

When did compound interest even get invented?

Compound interest when charged by lenders

Today “compound interest” usually relates to reinvested dividends and amortized growth/appreciation of investments (e.g., stocks, bonds) simply because non-predatory loans are designed for payoff within some fixed term. So if the term “compound interest” applies, something unexpected is happening (e.g., default) and the loan will be bundled and sold at a discount to collections.

Not far enough back to make a difference I’d wager

I’ll take that wager! 5k daily, ignoring inflation and leap-years, compounding annually (not quarterly) at 10% annualized ROI, gives us the standard annuity formula

1.1 * 5000 * 365 (1.1^n^-1) / 0.1

where n is the number of years, which

… in 100 years becomes ~278 billion (e11)

… in 200 years becomes ~3.8 million billion (e15)

… in 300 years becomes ~53 billion billion (e19)

… in 400 years becomes ~721 thousand billion billion (e23)

… in 533 years becomes ~231 billion billion billion (e29)

If that sounds incredible to you, you’re not alone. It’s the result of a hyperbolic growth curve that starts slow but keeps accelerating indefinitely, and 533 years is a very long time in market terms, so you easily reach the silly-numbers range.

Edit: the numbers before were napkin computation. I edited this to use the standard annuity formula which should be more accurate. Point should be the same though. Exponential growth is crazy.

100% agree with the point you're making and 100% disagree with the math that you did to get there.

[–] [email protected] 2 points 1 day ago* (last edited 23 hours ago)

Lol you’re right! It looks like the final number I gave was only for 400 years. I didn’t actually reach 533.

Also I was rounding numbers midway through like a pen and paper physics computation. Since that error scales exponentially, even if I had gotten to 533 the final number was guaranteed to be off.

Update: fixed it

[–] [email protected] 3 points 1 day ago (2 children)

even $1 at 1% compound interest gets ridiculous after a hundred years

[–] Sturgist 4 points 1 day ago

DAMN YOU AND YOUR MONSTER MATHS!

[–] [email protected] 3 points 1 day ago

I'm more interested about the 5k/d. That must be excluding compound interest. Like, all the money if just being stuffed into mattresses, or something. OTOH, having your money in a bank account might have reset you to zero in 1929.

[–] [email protected] 2 points 1 day ago (2 children)

Does this account for inflation?

[–] [email protected] 7 points 1 day ago

Can you even do that since this is before USD was a thing

[–] [email protected] 2 points 1 day ago* (last edited 1 day ago)

Inflation makes the money you earned longer ago worth less, so it would be an even less amicable comparison.

[–] [email protected] 0 points 1 day ago

Yeah but what if you have compound interest?
