# Pricing

The platform allows configurator builders to set the price of options. For example, if we have a configurator that allows customers to choose the color, for each color you can set a specific price. As customers switch between colors, the price is updated in real time. This would be a basic example, but in the platform you can add more complex pricing, such as **price groups**, **price tables**, **variables**, and use them in a **pricing formula**.

There are 3 key sections in the Pricing tab, discussed in more detail separately in each chapter: **Pricing Formula**, **Variables** and **Add price**.

* [**Price Formula**](/learning-the-app/products/pricing/pricing-formula.md) - In the price formula we have a field that supports basic mathematical calculation, such as: addition, subtraction, multiplication, division, and the use of parentheses. The price formula field also supports *variables* that can be added anywhere in a price formula by clicking on them in the Variables section.
* [**Variables**](/learning-the-app/products/pricing/variables.md) - There are 5 types of variables inside the platform: <mark style="color:purple;">**@total\_pricing**</mark>, <mark style="color:red;">**@base\_price,**</mark>**&#x20;**<mark style="color:green;">**@price\_options**</mark><mark style="color:red;">**,**</mark>**&#x20;**<mark style="color:orange;">**@price\_table**</mark> and <mark style="color:blue;">**@price\_variable**</mark>. All these variables can be used inside the price formula.
* [**Add price**](/learning-the-app/products/pricing/add-price.md) - From this section you will price your options using different pricing variables. The logic in adding a price, tax or any other cost is similar to adding option sets or when creating a contact form.
