You can preset Price List Analyzer configurations in your personal account in Seller Assistant.
Cost Settings belong to your team: there is one set for each marketplace, and every team member sees and can change the same set. Every new price list uses your team's Cost Settings, including price lists uploaded through the API or MCP (Business plan and higher). Purchase order profit is calculated with the same team settings.
To configure Price List Analyzer settings go to Tools/Price List Analyzer section and choose Cost Settings.
Then choose a specific Amazon marketplace where all these settings will be applied.
Notes
Preset configurations will be applied only to the selected Amazon marketplace. For different marketplaces you have to preset different calculator configurations.
The Seller Assistant extension keeps its own settings for each user. Changing your team's Cost Settings does not change your extension settings.
Price List Analyzer doesn't support all marketplaces. You can find a list of supported marketplaces in this article.
Price settings
Choose the default price type and how your profit is calculated:
Price type – select the price type used in your price list:
Each – price per unit
Case – price of one case. The price of one unit is calculated as Case Price ÷ Supplier Case Qty. If a product has no Supplier Case Qty, its price is used as it is.
Selling price calculation method:
Current BuyBox Price – by default
Average BuyBox Price for 30 days
Average BuyBox Price for 90 days
Average BuyBox Price for 180 days
Logistics
You can configure expenses for FBA and FBM logistics by switching between FBA and FBM:
Shipping Cost per pound (kg)
Shipping Cost per item
General Prep – cost of packaging or repackaging of goods, labeling
Fragile Prep – additional packaging for fragile goods or other costs for fragile goods (e.g. bubble wrapping)
Hazmat Fee – extra charge for products classified as hazardous materials
Oversize Fee – extra charge for products that are larger or heavier than standard limits
Note
Measurements and currency are automatically changed depending on the selected Amazon marketplace
Shipping is calculated by the formula:
FBA Shipping Costs = Actual Item Weight * FBA Shipping Cost per Pound + FBA Shipping Cost per Piece
FBM Shipping Costs = Actual Item Weight * FBM Shipping Cost per Pound + FBM Shipping Cost per Piece
FBA Storage and Placement Fees
You can also configure fees for storage and inbound placement. This settings section is available only when you select the FBA model:
Storage Fee period – a number of months, 1 to 12, used in the storage fee calculation.
Fee rate – Auto, Peak, or Standard. Peak switches the calculation to Q4 (peak season) rates instead of the current period's rates.
Inbound Placement Service Fee – the cost of spreading inventory across Amazon’s fulfillment centers close to customers.

VAT and VAT on Fees
You can configure Value Added Tax (VAT) – is a consumption tax that is added to the price of most goods and services. The rate of VAT charged on goods and services depends on the type of product.
Enter all the required rates in the fields based on the selected marketplace:
VAT Rate
VAT Reduced Rate
VAT on Seller's Fees
Then select whether VAT will be applied to the calculations from the list of schemes
VAT on Seller's Fees works on European marketplaces, and on Amazon US and Canada. The VAT result depends on your scheme:
Registered or reduced scheme: you see VAT Due. VAT Due is the VAT on the sale, minus the VAT on COG, minus the VAT on fees.
Non-registered scheme: you see Total VAT. Total VAT is the VAT on COG plus the VAT on fees. Profit is reduced by this total.
Selecting the "Cost of Goods Including VAT" checkbox means that VAT is already included in the COG you entered and will not be deducted additionally from the profit.
You can read some Examples of VAT settings.
Sales Tax
Retailers collect sales tax on orders shipped to addresses in states where a sales tax is applicable. The amount of tax charged varies depending on the state and local tax rates in the buyer's location. At the time of purchase, the sales tax charged will be displayed at checkout.
You need to choose sales tax due to certain state where you buy products.
Selecting the "Apply sales tax" checkbox means that tax will be added to the profit calculation.
You can also configure Digital Service Fee and Additional Expenses settings. Additional Expenses allow you to add extra costs per item:
Misc Fee Rate – a percentage of COG
Misc Fee – a fixed amount
You can view all the details of the profit calculation in the pop-up window that appears when you hover the cursor over the calculator icon in the profit field.
Change Cost Settings for one Price list
Inside an analyzed price list, you can change any costs and fees and the price settings, except the marketplace. Price List Analyzer immediately recalculates the data for each product in that price list. These changes apply only to this price list and do not change your team's Cost Settings.
When you reanalyze a price list, the new analysis keeps the Cost Settings of the price list it replaces.
If you change the settings while processing the price list, they will be applied, but the system will display a revert icon
next to the values that were calculated using the previous settings.
For the most accurate results, it's best to correct Cost Settings after the price list has been fully processed. Incorrect profit calculations can stem from misconfigured tax or expense settings. Always verify these components in the Price List Analyzer settings before interpreting results.
Do it with AI
These cost settings are changed in the UI. There is no MCP tool that writes them. Agents can start price list analyses, list your price lists and read their leads. See the Do it with AI section in Price List Analyzer.
