I had a chat with a friend recently who's using a fund manager services to invest for him in some US-based ETFs tracking the US indices.
I showed him using an online tool that those 2% annual fees he's paying to his fund manager are eating a lot of his profit overtime.
As I had some time, I decided to code this simulator in Pinescript because .... why not :) @RicardoSantos already did that Compound Interest function (tradingview.com/script/woq6TTda-FunctionCompoundInterest/) I added the n parameter being the number of times the interest is compounded per unit of time
Compound interest is calculated using the following formula
CI = P*(1 + R/n) (n*t) – P
Here,
P is the principal amount.
R is the annual interest rate.
t is the time the money is invested or borrowed for.
n is the number of times that interest is compounded per unit t, for example if interest is compounded monthly and t is in years then the value of n would be 12. If interest is compounded quarterly and t is in years then the value of n would be 4.
For now, the script only works on a yearly chart - I might update it later making it compatible with other chart timeframes - assuming there is some demand for it If there is, let me know in the comments down below
