How Much Does a Dollar Doubled Every Day for a Month End Up Being? (Video Explanation)
A dollar doubled every day for the 30 days that make up an average month would amount to $1,073,741,824. Yes, that is over a billion! This is much more than the one million offered in the other option (see below).
Assuming a genie just appeared before you and asked you to choose between these two options — giving you a dollar today and doubling it every day for 30 days or giving you $1 million today — which one would you choose? The truth is, most people would choose to have $1,000,000 today.
This raises the question: how much does a dollar doubled every day for a month end up being?
You start with $1 and then $2, $4, $8, $16…. By the end of the 30th day, you end up with $1,073,741,824! This is the power of compounding in action, and in this case, the rate is 100%, leading to staggering returns.

This is how it looks on a chart with linear scale:
One thing to notice from the table and chart is that the early days were modest. On the tenth day, you still had a tiny 512 dollars. On the 15th day, you have still a modest sixteen thousand. But now it starts getting interesting. The compounding effect kicks in!
By the 20th day, you have a very decent half a million dollars. Then, doubling half a million is pretty sweet! That means on day 21, you surpass a million. And from then on, your riches reach staggering amounts.
If you didn’t understand the principle of compounding, you would have been disappointed for not choosing the $1 million option.

Patience pays when it comes to growing wealth, and time is one of the most important factors in compounding money. The growth at later stages is always astronomical.
Mathematically, you can calculate the compounding formula:
A = P [1 + (rate)] ^ time
In this case:
P = $1 Rate = 100% Time = 29 days (because day 1 produced P, so the compounding starts from day 2)
A = $1 [1 + (1)] ^29
A = $1 [2] ^29
A = $107,374,182,400
The main factors in compounding are the rate and the time. If the rate wasn’t 100% (doubling) or the compounding period and duration weren’t daily for 30 days, the money may not compound to this amount.
