There are many tutorials and answers here how to add your script to be included in the page. But what I couldn't find is how to structure that code so it will work properly. This is due the $ being not used in this form of JQuery.

So here is my code and you can use that as a template.

jQuery(document).ready(function( $ ){
  $("#btnCalculate").click(function () {
        var val1 = $(".visits").val();
        var val2 = $(".collection").val();
        var val3 = $(".percent").val();
        var val4 = $(".expired").val();
        var val5 = $(".payer").val();
        var val6 = $(".deductible").val(); 
        var result = val1 * (val3 / 100) * 10 * 0.25;
        var result2 = val1 * val2 * (val4 / 100) * 0.2;
        var result3 = val1 * val2 * (val5 / 100) * 0.2;
        var result4 = val1 * val2 * (val6 / 100) * 0.1;
        var val7 = $(".pverify").val();
        var result5 = result + result2 + result3 + result4 - val7;
        var result6 = result5 * 12;
        $("#result").val("$" + result);
        $("#result2").val("$" + result2);
        $("#result3").val("$" + result3);
        $("#result4").val("$" + result4);
        $("#result5").val("$" + result5);
        $("#result6").val("$" + result6);
  });
});
