How to display number of posts in wordpress category including subcategories?

While listing category, I want to show how many posts are there including subcategories. I tried this:

$cat_parent_ID = isset( $cat_id->category_parent ) ? $cat_id->category_parent : '';

if ($cat_parent_ID == 0) {

$tag = $cat_id;

} else {

$tag = $cat_parent_ID;

$q = new WP_Query( array(
'nopaging' => true,
'tax_query' => array(
'taxonomy' => 'category',
'field' => 'id',
'terms' => $tag,
'include_children' => true,
'fields' => 'ids',
) );
$allPosts = $q->post_count;

echo $allPosts;

<?php _e( 'posts found', 'agrg' ); ?>

The above works fine if category has no childs. But if I click on category which has subcategories, I see
0 posts found
even if there are posts, but all of them are in subcategory (so 0 posts in parent category but some posts in subcategory)

Where did I go wrong and what should I change?

Try using this function:

function wp_get_cat_postcount($id) {
    $cat = get_category($id);
    $count = (int) $cat->count;
    $taxonomy = 'category';
    $args = array(
        'child_of' => $id,
    $tax_terms = get_terms($taxonomy,$args);
    foreach ($tax_terms as $tax_term) {
        $count +=$tax_term->count;

    return $count;

this function will return total post counts from the specified category and its child categories (if any), just by passing the category id. i hope it works for you, thanks..
