By default, opencart has only two prefixes for option prices.
When the admin chooses an option for the product, he must specify its price with a positive and negative prefix for the customer.
This can be very difficult on some products and we may even have to use a calculator.
This module adds six new items to this section so you can easily set the price of options, these include math symbols or a combination of them:

%
% -
% +
=
*

See the use of these symbols in the example below, you can also test them in the demo version.

Suppose you have a product with the following price:

Original product price = $ 100.00

With this plugin, you can specify the price of the options for this product as follows:

Price of the first option: (60%) Final price = $ 60.00

Price of the second option: (-10%) Final price = $ 90.00

Third option price: (+ 10%) Final price = $ 110.00

Fourth option price: (= 120) Final price = $ 120.00 [Full price]

Fifth option price: (* 2) Final price = $ 200.00

Sixth option price: (/ 2) Final price = $ 50.00

In addition to being very practical, this extension is also very small and simple.
