Final Price is a simple WooCommerce plugin that displays an extra total price box when the user updates the quantity of the selected product. The plugin works for Simple and variable products only.
The total price box shows above the add to cart button.
NOTE FOR DECIMAL PRECISION:
For decimal precision make sure that you set your required precision on WooCommerce Settings -> Currency Options -> Number of Decimals. The plugin uses that setting to conform with the current shop options.
PLEASE ASK ANY QUESTION BEFORE BUYING TO MAKE SURE THE PLUGIN WORKS THE WAY YOU WANT TO!
This functionality is included on our WooCommerce Extra Product Options plugin
