from you original post, what you want to do is detect if certain fields have changed, and if they have to run some code.

add_action('acf/save_post', 'my_acf_save_post', 1);
function my_acf_save_post($post_id) {
  // you need the field key of the field you want to check
  $field_to_check_key = 'field_012345678';
  $old_value = get_field('my_field_to_check', $post_id, false);
  // see if it is different than new value
  // also make sure the field key is set
  if (isset($_POST['acf'][$field_to_check]) &&
      $old_value != $_POST['acf'][$field_to_check]) {
    // value has change
    // call function to do calculations
  }
}
