Talk:Future value

old comments

Can someone please add the mathematical derivation of the FV_annuity formula from the regular/lump sum FV formula? (Same for the PV formulas).

See [[[time value of money]] for the derivations.--Gregalton 16:37, 3 January 2007 (UTC)

Wrong PHP formula

I think the current PHP formula is wrong. I think the proper formula is

<?php
function FV($p, $i, $t){ return round($p * (pow(1 + $i, $t) - 1) / $i, 2); }
?>

What is the purpose of having a code implementation? I doubt the vast majority of people reading the article care about how it is implemented in PHP (or any coding language for that matter). What does this add to the article? 76.122.102.100 (talk) 22:10, 30 August 2009 (UTC)

The relationship between the two equations....???

• :$FV=PV\cdot (1+rt)$ in this article

and

• :$I_{simp}=(r\cdot B_{0})\cdot m$ from the topic of Interest
