[PHP] mortgage calculator
I'd like to add a mortgage calculator to a client's site. I've been unable to find the formula. In searching php.net, I found a discussion from back in 2000 related to some buggy code. My web search hasn't produced anything other than realtor and mortgage companies and a perl script site. I'm not familiar with perl and would prefer avoiding it until my knowledge improves. There were corrections for a java script somewhere, but I'm beginning to think it is down. Some things seem so obvious that you just don't think you need to bookmark! So why can't I remember... I would just prefer not reinventing the wheel. Suggestions would be greatly appreciated. Karen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Actually, if you can read php, you can probably read perl; php is very perl-ish. If you *do* find it, I'd love to see a followup post :-) Heck, I'd even take the perl script location; I speak perl. In fact, I'm sure I can translate the perl script for a small fee; it shouldn't take long.

Re: [PHP] mortgage calculator
Karen, I am currently developing a class for mortgage calculations for our website. I forced one of our accounts to walk me through the calculations and the formula's. The class is still in an alpha stage but I would be more then willing to share my code when it is completed in 3+ weeks. Jonathan Pitcher On Wednesday, March 5, 2003, at 10:49 AM, Karen E.

At 17:49 5-3-03, you wrote: I'd like to add a mortgage calculator to a client's site. I've been unable to find the formula. Well the calculation depends on the companies policy of course. 1. Normal rent calculation would go like this: where i = interest or rent over a certain the period of time ( usually between 0 and 1 (1=100%). With 3.5% interest, i is 3.5/100=0.035 n = the amount of timeperiods that passed $ = pack of money , and $(0) is heap at start, $(n) is at end of n timeperiods $(n)= $(0) * (1+i)^n (x raised-to-the-power-of y is sometimes written as x^y, sometimes as x**y (Perl)) in PHP $startsum=$_POST['startsum']; $interest=$_POST['interest']; $timeperiods=$_POST['timeperiods']; $endsum = $startsum * pow(1+$interest/100,$timeperiods); With a 3% year-rent in 5 years $10 grows to $(n) = 10 * 1.03^5 2. Mortgage calculation Well how do they pay back? You can have them pay a fixed part of the loan plus the interest of the month, here called an annuiteiten-hypotheek Then every month you pay ($in_this_month *interest) + (1/$totalmonths * $startsum ) $in_this_month is probably $n=thismonths number so the monthly payment would look something like ((1 - $n/$totalmonths) * $startsum ) + (1/$totalmonths * $startsum ) I suppose you can simplify this if you are a mathematician. If you are a bloody consultant you should have learned these formulas once up on a time. You can loop through $n of course to make a nice list.

Perl is not that hard to translate to PHP if it is clear what every variable means. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] mortgage calculator
Thanks, Mark! I haven't checked it in detail yet, but if nothing else it has the formula for which I was searching.

RE: [PHP] mortgage calculator
WOW! This list has been a wonderful resource! Thanks to all of you. To top it off I have learned a great new technique for google search, start in the back end of relevance! (You probably all know that, but for some reason I never made the connection.) In addition to the site that Mark mentioned, http://www.karakas-online.de/myServices/showfile.php?highlight=mortgage was included among others. David, the link to the perl script is http://www.nohope.net/perl/ I'm not a Perlie so I didn't check it. Considering my many hats, I confess to have learned the formula long ago, but couldn't get my hands on the formula when I needed it. Frustrating and I won't even go there. Thanks to all!
