suppose you have a balance in a bank account call it p
this bank is very generous and they offer you 12% interest rate
you had p in your account after 1 year how much you should get?
P+12%P=P(1+12/100)
after 6 years it should be P(1+12/100)^6

xapproachesinfinity · Answer

in more general situation we denote rate of interest by r
and there are other things involved like how many compounds are interested about
like instead of a year you want to know how much you will earn in half a year or even daily
and so on
