hi Banon,

Arhh yes! Good point.

You could solve it graphically like this;

using … p;ymax=1.2

I've chosen r = 0.05 and you have to have x instead of n.

You can put y = FV/PV as the second graph and zoom in on the point where the line cuts the curve.

Hi Banon;

You can not always solve for any variable you want. In this case I do not think you can get n by itself on the left.

Sorry,but i couldn't find any formula for n there.There is the formula Fv=Pv(1+r/n)^(nt) but i don't know how to solve that expression for n.

hi Banon,

I'm assuming you mean 'if I know all the variables except n, how do I work it out?' … l#periodic

Half way down the page is the formula for this.

In periodic interest if I know everything except number of  compoundings per year,how do I find it?
