OK.. Math is NOT my forte ...
I am converting a site from ASP to PHP ... And this calc is in the ASP Code
:
$nMonthlyInterest = $nRate / (12 * 100)
//' Calculate monthly payment
$nPayment = $nPrincipal * ( $nMonthlyInterest / (1 - (1 +
$nMonthlyInterest) ^ -$iMonths))
Which then
I believe what you are looking is:

Right ... But that is producing even funkier results...
doing pow( (1-(1+$nMonthlyInterest)) , ($iMonths*-1) ) ;

You originally had:
$nPrincipal * ( $nMonthlyInterest / (1 - (1 + $nMonthlyInterest) ^ -
$iMonths))
which, translate to in PHP
$nPrincipal * ( $nMonthlyInterest / (1 - pow( ( 1 +
$nMonthlyInterest ), -$iMonths ) ) )

I think you need to do pow((1+$nMonthlyInterest),($iMonths*-1))
