You might try the change event, I've often used it in such contexts.
It's more useful than blur, because it fires at the same moment but
*only* when the value of the input has actually been changed.

You might create a large "Calculate" button. Either it gets a click
event of its own, or it only serves to secretly activate the
blur/change event on other form fields when the user clicks on it.

Test what happens when the user hits Return or Tab. Sometimes scripts
fire at an awkward moment in such situations.
