Fee estimator
Estimate Amazon's referral and FBA fees for a price before you list or reprice — one item or a batch — by conversation or by code.
In short
Name a price; your agent returns Amazon's own fee estimate — referral fee, FBA fee and the total — so the margin is known before you list, reprice or send stock.
In your daily workflow
- One ASIN —
productFees_getMyFeesEstimateForASINestimates the fees for any ASIN at a price you give. - Your SKU —
productFees_getMyFeesEstimateForSKUdoes the same for one of your own listings. - A whole list —
productFees_getMyFeesEstimatesestimates many items in one call; your agent writes them to your sheet beside your costs.
Try asking
"If I price this SKU at 29.99, what are the referral and FBA fees, and my net margin?"
"Estimate Amazon fees for B0EXAMPLE1 at 29.99."
"Calculate fees for all my FBA products at their current prices."
An estimate, both ways
MCP — you ask: "What would Amazon charge on B0EXAMPLE1 at 29.99, fulfilled by Amazon?" Your agent calls productFees_getMyFeesEstimateForASIN.
