Hi again @nicewp123,

The following mu-plugin can help you to achieve it. You will need to change the form ID from 2910 to your form’s ID in this line
if ( e.target.id == 'forminator-module-2910' ) { (edited)

add_action('wp_footer', 'wpmudev_update_calculation_instant', 9999);
function wpmudev_update_calculation_instant(){
	global $post;
    if ( is_a( $post, 'WP_Post' ) && !has_shortcode($post->post_content, 'forminator_form') ) {
        return;
    }
	?>
	<script type="text/javascript">
	jQuery(document).ready(function($){
		setTimeout(function() {
			$('.forminator-custom-form').trigger('after.load.forminator');
		},100);

		$(document).on('after.load.forminator', function(e, form_id) {
			if ( e.target.id == 'forminator-module-2910' ) {
				var typingTimer;
				var doneTypingInterval = 500;
				var $input = $('.forminator-number--field');

				$input.each(function() {
					$(this).on('keyup', function () {
						clearTimeout(typingTimer);
						typingTimer = setTimeout(doneTyping, doneTypingInterval);
					});

					$(this).on('keydown', function () {
						clearTimeout(typingTimer);
					});
				})

				function doneTyping () {
					$input.trigger('change');
				}
			}
		});
	});
	</script>
	<?php
}
