Revenue Calculator API - Amazon FBA/MFN Fee Estimation

API Description

The Revenue Calculator API connects directly to Amazon’s official fee service. Given a product ASIN and a target marketplace, it returns a fee breakdown for both FBA (Fulfilled by Amazon) and MFN (Merchant Fulfilled) modes — including the fulfillment fee, referral fee, and monthly storage fee — to support product sourcing and profit estimation.
You can pass just asin + country to use smart defaults (the product’s current price, dimensions, and weight are applied automatically), or override the sale price, shipping cost, package dimensions, and weight to model your exact cost structure.

Response

The returned data contains three parts: product (product info), summary (fee summary), and raw (Amazon’s original fee breakdown).

data.summary — Fee Summary

Field	Type	Description
FBA.fulfillmentFee	number	FBA fulfillment fee (not present for MFN)
FBA.referralFee	number	FBA referral fee, net (promotion already deducted; a percentage of the sale price — when no sale price is provided it is computed against the fallback price of 1, so it will be very small)
FBA.referralFeeBase	number	Base referral fee (before promotion deduction; present even when 0 — only omitted if Amazon does not return this fee item)
FBA.referralFeePromotion	number	Referral fee promotion discount (0 when none; only omitted if Amazon does not return this fee item)
FBA.fixedClosingFee	number	Fixed closing fee (applies to media products, usually 0 otherwise; only omitted if Amazon does not return this fee item)
FBA.amazonFeeTotal	number	Amazon fee total = base referral fee + fixed closing fee (matches the “Amazon fees” row on the official site)
FBA.storageFeePeak	number	Peak-season monthly storage fee (per unit)
FBA.storageFeeNonPeak	number	Off-peak monthly storage fee (per unit)
FBA.totalCost	number	FBA total = fulfillment fee + net referral fee + fixed closing fee (storage fee excluded, listed separately)
FBA.profit	number	Net profit = price − (totalCost + off-peak storage fee), matches the official “Net profit” row. When `fbaPrice` is not provided and the product’s current price cannot be fetched, price falls back to 1, making profit mostly negative and meaningless — always pass a real `fbaPrice` to estimate profit
FBA.profitRate	number	Net profit margin (%) = profit / price × 100 (2 decimals), matches the official “Net margin” row. Meaningless under the fallback price of 1, same as profit
FBA.currency	string	Currency (USD for US, JPY for JP)
MFN.referralFee	number	MFN net referral fee
MFN.referralFeeBase	number	Base referral fee (same as FBA)
MFN.referralFeePromotion	number	Referral fee promotion discount (same as FBA)
MFN.fixedClosingFee	number	Fixed closing fee (same as FBA)
MFN.amazonFeeTotal	number	Amazon fee total = base referral fee + fixed closing fee
MFN.totalCost	number	MFN total = net referral fee + fixed closing fee (no storage fee for self-fulfillment)
MFN.profit	number	Net profit = price − totalCost (no storage for self-fulfillment). Meaningless under the fallback price of 1, same as FBA.profit
MFN.profitRate	number	Net profit margin (%) = profit / price × 100 (2 decimals). Same as profit
MFN.currency	string	Currency

data.product — Product Info

Field	Type	Description
asin	string	Product ASIN
price	number	The sale price actually used for calculation (the `fbaPrice` value when provided, otherwise the product’s current price; falls back to 1 when neither is available). Matches the “Item price” input on the official site
title	string	Product title
imageUrl	string	Product main image URL
glProductGroupName	string	Product group / category (Amazon internal classification)
salesRank	int	Sales rank (may be null for some products)
dimension	object	Dimensions, containing `length`, `width`, `height`, `unit`. Note: Amazon’s anonymous fee API does not return product dimensions, so length/width/height are always 0 unless you pass `packageLength/Width/Height` (Amazon uses its internal dimensions to compute the fulfillment fee but does not return them here). Pass the parameters to estimate by real dimensions
weight	object	Weight, containing `value`, `unit`. Same as dimensions — `value` is always 0 unless `packageWeight` is provided. Pass `packageWeight` to estimate by real weight

data.raw — Amazon Original Fee Breakdown

Field	Type	Description
raw	object	The complete original payload from Amazon’s fee service, containing every fee item under `programFeeResultMap` (`Core#0` for FBA, `MFN#1` for MFN) — including optional fees not rolled up into `summary`, such as bubble-wrap, labeling, and removal fees. Use this node when you need finer-grained fee items.

}'

Response Example

The example below passes fbaPrice: 49.99, so referral fee, net profit, and margin are all meaningful real values. referralFee (net) = referralFeeBase − referralFeePromotion; amazonFeeTotal = referralFeeBase + fixedClosingFee; totalCost includes fixedClosingFee; profit = price − (totalCost + storageFeeNonPeak) (MFN has no storage).

Custom Price & Dimensions Example

When fbaPrice is provided, the referral fee is recalculated based on the sale price:

curl https://scrapeapi.pangolinfo.com/api/v1/revenue-calculator \
  --request POST \
  --header 'Authorization: ' \
  --header 'Content-Type: application/json' \
  --data '{
  "asin": "B07FZ8S74R",
  "country": "US",
  "fbaPrice": 49.99,
  "packageWeight": 1.2,
  "weightUnit": "pounds"
}'

Send requests serially to avoid rate limiting. This API connects directly to Amazon’s official fee service, which rate-limits by source IP with a relatively low threshold. High concurrency (QPS ≥ 3) triggers rate limiting and returns 4030 (service busy) or 1002 (system busy). Call serially and keep the request rate low; if you hit these codes, simply retry after a short wait (rate-limited failures do not consume credits).
