Investment/Loan Graph

Working on a new Investment/Loan Graph

Does it make sense? Does it do the calcs correctly? Any suggestions?

Re: Investment/Loan Graph

Hi MIF;

Very nice looking interface. So far it is doing everything correct.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

Re: Investment/Loan Graph

hi MathsIsFun,

I'm confused.  Raw? PV NPV etc ?

I looked at your interest and compound interest pages and so I think PV means 'present value'.

But you used FV for 'future value',  so what is NPV ?

And why is the 2000 negative ?  Does that mean it is a loan rather than an investment ?

Maybe a key to the terminology is needed.  (Well, it is for dummies like me smile )
