Mortgage Calculator

AngularJS Factory for calculating mortgage affordability.

###Setup

The factory doesn't have any outside dependencies. Was originally built to work with rangeSlider directive.

Make sure that the file is loaded on your index.html

<script type="text/javascript" src="path_to_factory/affordability.js"></script>`

Include it in the controller

App.controller('SomeController', ['$scope', 'MortageAffordabilityCalculator', function($scope, MortageAffordabilityCalculator) {

  $scope.calculator = MortageAffordabilityCalculator;

}])

Required Fields

The minimum required fields for calculator to work are:

• Term in Months
• APR/Interest rate
• Gross annual income

The rest are optional and give a much more accurate result

Declare a model object in order to pass the parameters to the factor,

$scope.someModel = {
  termInMonths: 360,
  interestRate: 5,
  income: 50000
}

Factory takes a single object argument and splits it up internally.

$scope.calculator.calculateAffordability($scope.someModel)

$scope.calculateAffordability = function(){
  $scope.calculator.calculateRange($scope.someModel);
  $scope.calculator.calculateDetails($scope.calculator.calculated.monthlyPayment);
}

Mark Up

<form>
  <input type="text" ng-model="someModel.termInMonths" />
  <input type="text" ng-model="someModel.interestRate" />
  <input type="text" ng-model="someModel.income" />
  <button ng-click="calculateAffordability()"></button>
</form>


<div>
  <h4>Maximum you can afford</h4>
  <span>{{calculator.calculated.priceCeiling}}</span>
</div>
<div>
  <h4>Monthly Payment</h4>
  <span>{{calculator.calculated.monthlyPayment}}</span>
</div>
