# Prices how-to

To calculate prices and taxes, we first need to get the proper tax rate. It's based on the taxrate entity, and stored in the Elastic. Each product can have the property product.tax_class_id fixed. According to its value, Storefront API applies the taxrate. It also applies the country and region to the filter.

Note: We currently do not support searching the tax rules by customer_tax_class_id or by the tax_postcode fields of the taxrate entity. Pull requests are more than welcome 😉

After getting the right tax rate, we can calculate the prices.

We've got the following price fields priority in VS:

• final_price - if set, depending on the config.tax.finalPriceIncludesTax, it's taken as the final price or Net final price.
• special_price - if set and lower than the price, it will replace the price and the price value will be set into the original_price property.
• price - if set, depending on the config.tax.sourcePriceIncludesTax, it's taken as the final price or Net final price.

Depending on the config.tax.finalPriceIncludesTax and config.tax.sourcePriceIncludesTax settings, Vue Storefront calculates the prices and stores them into the following fields:

Product Special price:

• special_price - optional - if set, it's always the Net price.
• special_price_incl_tax - optional - if set, it's always the price after taxes.
• special_price_tax - optional - if set, it's the tax amount.

Product Regular price:

• price - required - if set, it's always the Net price.
• price_incl_tax - required - if set, it's always the price after taxes.
• price_tax - required - if set, it's the tax amount.

Product Final price:

• final_price - optional - if set, it's always the Net price.
• final_price_incl_tax - optional - if set, it's always the price after taxes.
• final_price_tax - optional - if set, it's the tax amount.

Product Original price (set only if final_price or special_price are lower than price):

• original_price - optional - if set, it's always the Net price.
• original_price_incl_tax - optional - if set, it's always the price after taxes.
• original_price_tax - optional - if set, it's the tax amount.

Note: The prices are set for all configurable_children with the same format. Note: If any of the configurable_children has a price lower than the main product price, the main product price will be updated accordingly.
