Add Charge by Percentage
Overview#
The Add Charge by Percentage feature allows you to increase the product price by a percentage instead of using a fixed amount.
For example, if a product costs $100 and you set an Add Charge of 20%, the additional charge will be $20, bringing the total product price to $120.
How to set up Add Charge by Percentage#
Step 1: Create an Option Set
From the Aris Option dashboard, create a new Option Set or open an existing one.

Step 2: Create an option
Add a new option to the Option Set, then enter the option name and its values.

Step 3: Choose Add Charge by Percentage
Find the option value that requires an additional charge. Open its pricing settings, select Add Charge, and choose Percentage (%) as the calculation type.

Enter the percentage you want to add to the product price.

Step 4: Assign products and save
Assign the Option Set to the products where you want the option to appear, then click Save.

Preview on the online store#
Open the assigned product on your online store and select the option value. The additional charge will be calculated automatically based on the product price.

Note: Because the charge is calculated as a percentage of the product price, the additional amount may vary between products or variants with different prices.
