The math equation to calculate the amount of money after 30 days with a penny doubling daily can be expressed as: Amount = 0.01 * (2^30) In this equation, "2^30" represents 2 raised to the power of 30 (i.e., doubling daily for 30 days). The result will give you the amount of money accumulated after 30 days.
Assuming that you have 1 cent before you start, and for each of the following 30 days double the number of cents, you would have 230 cents on the 30th day. In the US, this would be $10,737,418.24 USD on the final doubling. If you keep the cents as they are doubled, then the total for all 30 days, plus your original 1 cent, will be (231 - 1) or $ 21,474,836.47 USD in all.

If you got a penny on the first day, two more pennies on the second day, four more pennies on the third day, and so on, doubling every day, then: -- On the 17th day, you would get $655.36, pushing your total to $1,310.71 -- The 18th day is the first time you would get more than $1,000 in one day. On that day, you would get $1,310.72, and your total would be $2,621.43 .
Take the penny a day doubled every day. The sum would be almost 43,000,000.
If you keep doubling the total, at the end of one day you'd have two cents. At the end of the first week, you'd have $1.28. At the end of 100 days, you'd be wealthy beyond your wildest dreams. If you keep doubling the same penny, at the end of 100 days you'd have a couple bucks.
Assuming you did not add the pennies, but merely doubled the amount, on the 365th day, you would have 2364 pennies = about 3.76 x 10107 dollars, which is an implausibly large sum of money. The gross domestic product of the entire Earth is only about 80 to 90 x 1012 dollars. 10107 is trillions of times the total number of electrons in the universe. If you kept each group of pennies as you doubled, you would have (2365 - 1) pennies, or almost exactly twice as much money.

Using 30 days for "one month", I get $ 107,374,182.40

Assuming 365 days: Doubling a penny 365 days means you would have 2365 pennies after 365 days. That's something on the order of 3.76 x 10109 cents, which is about $3.76 x 10107 in cold, hard American cash.

The amount is equal about .005e693x. More exactly (at least for the next 30 days), y = .005e69314718058x, where x = amount of days and y = amount you would receive on that day. Also, if you start with 2 pennies then the coefficient would change to .01.
