How are Amazon fees included in profit calculations?

Amazon marketplace fees are automatically included in MerchantSpring profit calculations using financial event data retrieved directly from Amazon’s APIs.

Each fee charged by Amazon is recorded as a financial event and categorized within MerchantSpring’s reporting system.

These fees are deducted from revenue when calculating profit.

Common Amazon Fees Included

MerchantSpring retrieves several types of fees from Amazon financial data.

Referral Fees

Referral fees are charged as a percentage of the sale price and vary depending on the product category.

Fulfilment Fees

For products fulfilled by Amazon (FBA), fulfilment fees cover:

• picking and packing
• shipping
• customer service
• returns processing

These fees are applied on a per-order basis.

Storage Fees

Inventory stored in Amazon warehouses incurs storage fees.

These include both standard monthly storage costs and long-term storage charges.

Shipping and Handling Charges

Depending on the fulfilment method, additional shipping-related costs may be applied.

Refund Processing Fees

When refunds occur, Amazon may charge processing fees or retain portions of previously charged fees.

These are included in financial event data.

How MerchantSpring Uses Fee Data

MerchantSpring processes these financial events to calculate:

• product-level profitability
• order-level profit
• channel profitability
• overall business margin

Because fees are retrieved directly from Amazon’s accounting records, they reflect the same financial structure used within Amazon’s settlement system.

Notes: 

• Fee adjustments may appear after the initial transaction.
• Profit figures may update as additional financial events are posted.
• Amazon occasionally corrects or adjusts previously recorded fees.
