Подсчитать сумму в input

Есть динамическая таблица после выбора товара заплетаться сумма

<td><input type='text' class='total"+(i+1)+"' name='oll_total[]' value='' ></td>

таких полей может быть много, получается так

<td><input type='text' class='total1' name='oll_total[]' value='100'></td>
<td><input type='text' class='total2' name='oll_total[]' value='200'></td>
<td><input type='text' class='total3' name='oll_total[]' value='300'></td>
<td><input type='text' class='total4' name='oll_total[]' value='400'></td>
<td><input type='text' class='total5' name='oll_total[]' value='500'></td>

пробую сделать так

var i = 1;
var sum= 0;
$("input.total"+i).each(function(){
sum += $(this).val();
});
console.log(sum);

результат = 0; Подскажите как можно подсчитать сумму.
