#### Calculations

The actionscript goes on frame 2 of the actions layer .It calcuates the mortage repayment. I don't want to confuse matters with explaining how the mortgage calculations work. I'm not sure that I understand it myself!!

```//calculate interest rate applicable to period
var periodicInterestRate = floInterest/intRepayments/100;

//length in periods
var TotPeriods = intTerm * intRepayments;

//periodic interest
var PeriodicInterest = intPrincipal * periodicInterestRate;
var base = 1;
var mbase = 1 + periodicInterestRate;
for (var i=0; i < TotPeriods; i++){
base = base * mbase;
}

//calculate Total Repayment
TotRepayment = floor(intPrincipal * periodicInterestRate / ( 1 - (1/base)));
```

Test the movie. Enter some figures and test the calculation.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
