very tricky

Anon

hi i've created a form only on the last page i need to do a bit of tricky coding, here is what i have: if $ontheroad=2000, $deposit=500 and $repayover=24.

$balance = $ontheroad-$deposit;

if ($balance < 5000) {

$interest = "$balance+6.5%-$balance";
$totalinterest = "$interest/12*$repayover";
$totalrepay = "$totalinterest+$balance/$repayover+20%";
totalrepayment = "$totalrepay";
}

does anyone know why this won't work and if so how can i fix it, thanks Martin

if $ontheroad=2000, $deposit=500 and $repayover=24 ???

Should be:

if ($ontheroad == 200 AND $deposit == 500 AND $repayover == 24) {
$balance = $ontheroad-$deposit;
}

sorry my mistake the amount can varie, what happens is they enter the amount, deposit and number of months on the page before and then when they click continue it goes to the page with a total each month which consists of:

$balance = $ontheroad-$deposit;

if ($balance < 5000) {

$interest = "$balance+6.5%-$balance";
$totalinterest = "$interest/12*$repayover";
$totalrepay = "$totalinterest+$balance/$repayover+20%";
totalrepayment = "$totalrepay";
}

else {
$interest = "$balance+7.5%-$balance";
$totalinterest = "$interest/12*$repayover";
$totalrepay = "$totalinterest+$balance/$repayover+20%";
totalrepayment = "$totalrepay";
}

if the balance is less than £5000 theres a different interest rate.

sorry about the confusion, my mistake, thanks Martin

Tjek out this:
$totalrepay = "$totalinterest+$balance/$repayover+20%";
In the school you learn that is means:
$totalrepay = "$totalinterest+ ( $balance/$repayover ) +20%";
But you want to "+" first, right???
$totalrepay = "($totalinterest+$balance)/($repayover+20%)";
And 20% of what? total or repayover?

Something like :

if ($balance < 5000) {

$interest = $balance .065;
$totalinterest = ($interest/12) $repayover;
$totalrepay = number_format( ($totalinterest + $balance) / ($repayover * 1.20),2 );
}

The line:

$interest = "$balance+6.5%-$balance";

Will create the string:

1500+6.5%-1500

Which is surely not what you want. Perhaps you want something like:

$interest = $balance*.065;

But, more to the point, if you are looking at amortizing a loan the way lenders do, this approach will not work at all! You will need to use the correct formula, which, I believe, is based on a mathematical series. It is not as simple as figuring the total interest and dividing it over the length of the loan, because you pay far more interest than principal in the beginning of the term, and the reverse is true at the end.
