Show real-time calculation on Numeric question

I have a numeric question (how many times do you....per month) and my client would like me to show the yearly calculation at the same time (so if you enter 6 you can show 72 times per year.

I set up a span tag but until you click out of the entry box of the numeric question it won't show. A suggestions?

Here is what I'm using:

<script type="text/javascript">
jQuery(document).ready(function(){
    document.getElementById("Q6").onblur=function(){UpdateQ6()};
});
 
function UpdateQ6 ()
{
    var myspan = document.getElementById("Q6span");
    myspan.innerHTML=SSI_GetValue("Q6")*12;
}
</script>
