This might be retarded question, but I've managed to do it by hand in the end, since I can't find the formula.. but let's say I start with 5k$ and my average monthly return is 5% (which adds up to 60% per year). Each month I also re-invest my 5% monthly earning and increase my capital.

So basically, how much will I earn in 5 years, if I start with 5k$, average 5% monthly return and reinvest my earnings every month?

How the fuck is this formula called, I found compound reinvestment calculator and I don't even know what else, but I just get the wrong results.

For some reason, I have a bad feeling about asking this here, since most of you are stupid. Why the fuck do I get this right by calculating it on hand, but can't find the correct formula.

>average 5% monthly return

Won't happen from day trading. Possibly if you buy and hold a solid alt, for example bnb is OBVIOUSLY going to do 60% this year. Or something like banyan which will do that in a week.

Why do you assume it's from crypto market?

I've been doing a lot of forex lately and had great results/calls and feel ready to jump in. 5% is conservative return, given I averaged a lot more.

why don't you fucking write a function to do it? it's literally a few lines in python
def monthly_compound_interest(months, capital, interest):
for _ in range(months):
capital += interest/100 * capital
return capital

this works if you input interest in value as if it was %, also you can generalize it more to make it work for daily compund etc., but not going to do everything for you

Fucking brainlets need to program for the simplest calculations.

If you reinvest each month at 5% per month, the formula is :

Money after n months = initial*(1.05)^n

n=5*12=60 for your 5 years

There's a closed from solution with this, doing it iteratively is a waste of time.

Firstly, if you're getting an average monthly return of 5%, then it compounds up to MORE than 60%, namely it compounds up to 79%.

Anyway, the formula is just 5k * 1.05^(5*12) which is 93k

You are not making 5% a month trading over the long term

You are a 100% lucky with those returns. Most great traders are correct 55% of the time.

We'll see, it just an estimation for now given great results last few months.

Thought I missed that.
