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.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

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 )
