# How Much Does a Dollar Doubled Every Day for a Month End Up Being? (Dollar Doubler Calculator + Video)

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 â€” giving you a dollar today and doubling it every day for 30 days or giving you$1 million today â€” 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. (We provided a calculator at the bottom of the article that creates a table and a diagram.) 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.

## Dollar Doubled Every Day Formula and calculation

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.
