You can preset configurations in your personal account in Seller Assistant which will be automatically applied in calculator.
To configure extension settings go to "Extensions/Seller Assistant" section and choose "Extension Settings".
Then choose a specific Amazon marketplace where all these settings will be applied.
Note
Preset configurations will be applied only to the selected Amazon marketplace. For different marketplaces you have to preset different calculator configurations.
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
Costs of logistics and packaging of the goods are displayed in logistics costs section in Seller Assistant extension.
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.
Read more about Inbound Placement Service Fee settings.
This is the same setting as in the Seller Assistant extension – changing it here or in the extension updates the same value everywhere.
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.
The Seller Assistant extension calculator uses these settings on European marketplaces too. It shows a VAT panel directly under Total Fees, on the product page and in the side panel. The panel header shows VAT Due or Total VAT, with the amount. Open the panel to see three lines, each with its own dropdown:
VAT: the VAT on the sale for your scheme (No VAT, Standard, Reduced or Non Registered). On a non-registered scheme it is 0.
VAT on Fees: your VAT on fees rate applied to the Amazon fees. Hover the amount to see the VAT on each fee.
VAT on COG: the VAT on your cost of goods. Choose whether your COG includes or excludes VAT.
Hover Profit to see the full breakdown. For each line (selling price, each Amazon fee, cost of goods, logistics and additional expenses) it shows the cost, the VAT and the total, then VAT Due or Total VAT, then Profit. On Amazon US and Canada, the breakdown has no VAT columns. It shows a VAT on Referral Fee row when that amount is not 0.
The VAT panel and this Profit breakdown are in the Seller Assistant extension for Chrome from version 1.39.0. If you don't see them yet, your installed extension may not have updated to that version. You can check the version on the chrome://extensions page.
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
