hello out there, maybe you have heard it said,that great minds can't do simple math. e.g. einstein. now to save myself the embarrassment of asking such a simple question, let me just say first; my knowledge of math is so vast that there are many gaps.

QUESTION: WHAT IS THE FORMULA FOR FINDING PERCENTAGE IN MONATARY GAIN OR LOSS ?


ok, so i'm a rookie in the math department, throw me a frikkin bone here.

I could be wrong.

Future value formula, fv=P(1+r/n)n*t
Fv = future value.
P = princinple or the initial investment
r = the annual interest rate
n = the number of times per year the interest is compounded
t = the number of year interest will accrue

So,

P=fv/(1+r/n)n*t = solve for p
t=log(fv/p)/(n*log(1+r/n)) = solve for t
r=nx(n*t (INSERT SQUARE ROOT) fv/p-1) = solve for r
