WooCommerce: Calculate Subtotal On Quantity Increment @ Single Product

by Tutor Aspire

From a UX point of view, ecommerce customers may enjoy a little improvement on the WooCommerce single product page. As soon as they increase the add to cart quantity, it’d be nice if product price could be recalculated or maybe if a “TOTAL” line could appear so that users always know how much they are about to add to cart.

Honestly, this is hard to explain it this way, so the best is if you look at the screenshot. Enjoy!

Product price is $34 and quantity is 10, therefore the “Total” is now $340. Whenever quantity changes, “Total” updates its value.
