sum value radiobuttons javascript

Does anyone know how to sum the total of the values. And I would like to multiply the total with 1072. I tried it a littlebit. But that didn't work out very well..

So I would like a javascript code where the total of the 4 values that are marked will be calculated.

   <html>   
    <head>
        <h2>Inboedelwaardemeter</h2>
        <script type="text/javascript">
            function sumCheckedRadioButtons() {
                  var sum = 0;
                  $('input[type=radio]:checked').each(function(i, el) {
                    sum += Number($(el).val());
                  });
                  return sum;
                }
                $('#show_sum').on('click', function() {
                    alert(sumCheckedRadioButtons());
                });
        </script>
    </head> 
    <body>
        <br>
        <b> Leeftijd hoofdkostwinner:</b>

The following is a vanilla js solution:

function checkTotal() {
   var a =  document.querySelectorAll('input:checked'); 
   var total = 0;
   for(var x=0; x < a.length;x++){
      total += a[x].value * 1;
   }
   alert(total);
}

Note: queryselector is available in (relatively) modern browsers only http://caniuse.com/queryselector

Example here: http://jsfiddle.net/2eU4E/1/

Using jQuery you can simply select all radio buttons which are checked and add their numerical value to a sum:

function sumCheckedRadioButtons() {
  var sum = 0;
  $('input[type=radio]:checked').each(function(i, el) {
    sum += Number($(el).val());
  });
  return sum;
}

Here is a working jsFiddle (press the "Show Sum" button at the bottom of the "Result" pane).
