John,

Thanks for pointing me to the two functions as a starting point. I was able to put together the following, and it worked perfect. Appreciate the help.

Code:

function my_acf_save_post( $post_id ) {
    
// get new value
$costInDollars = get_field('cost_in_dollars');
$discountInDollars = get_field('discount_in_dollars');
    
// do something
$totalCostInDollars = $costInDollars - $discountInDollars;
update_field('total_cost_in_dollars', $totalCostInDollars, $post_id);
	
}

add_action('acf/save_post', 'my_acf_save_post', 20);
