Make array from multiple dynamic input textboxes

Question

I'm trying to get 3 different array readouts of the values added after I click on submit, can someone please help me. I would like it to look something like this...

balance_array = 1,2,3,4,5,6 and so on...

loan_array = 1,2,3,4,5,6 and so on...

rate_array = 1,2,3,4,5,6 and so on...

I guess the real question is how do I get the value of balance0,balance1 and so on.. and add it to an array and then I can repeat that for the others also.

The array values can be captured by naming the div's with appropriate class for example:

<input class="form-control rate" name="rate" type="text" placeholder="Interest Rate" required="required" />

And then reading the values by classname on submit event:

$(document).ready(function(){
     $('#submit').click(function(e){
         e.preventDefault();
         var balanceArray = [];
         var rateArray = [];
         var paymentArray = []  
         $('.balance').each(function(item){
            balanceArray.push($(this).val());  
         });
         $('.rate').each(function(item){
            rateArray.push($(this).val());  
         });
         $('.payment').each(function(item){
            paymentArray.push($(this).val());  
         });
    });
});
