Hello, I'm looking for a formula where I can find out how much money I will make over time. Clearly this isn't a real strategy, but I'm just trying to use it to illustrate a point. Here's the lowdown:

Suppose I start with $10,000. I invest it in a stock at a price, which is irrelevant. By the end of the day I sell all the shares for a 3% profit. The next day I take that 10k + the 3% profit ($10,300) and invest that in a stock. By the end of the day I sell that stock for a 3% profit. The next day I do the same with the $10,609. Etc etc. I would also like this formula to assume a state capital gains tax of 3% and a federal capital gains tax of 28%.

I want to be able to use this formula to demonstrate how much gross profit I will have by the end of n number of days, using different initial investment amounts and different daily % returns on the investment.

Again, this isn't a real world scenario, but I appreciate any help and insight on this. Thank you in advance.

Is there any particular reason that you're not able ("allowed"?) to use the compound-interest formula?
