Enter the selling price, referral fee percentage, FBA fulfillment fee, and estimated storage or platform fee. The calculator shows the total fee and the payout left before product cost.
Fee ratio shows how much of your selling price is consumed by Amazon-related charges. A high ratio may require a price increase, smaller package, or different fulfillment approach.
Actual fees vary by category, size tier, weight, country, and promotion type.
A $50 item with a 15% referral fee, $5.50 FBA fee, and $0.75 storage allowance has $13.75 in estimated Amazon fees and a 27.5% fee ratio.
Amazon usually charges a referral fee plus fulfillment or other service fees. The exact amount depends on category, selling price, size, weight, and fulfillment method.
Common deductions include referral fees, FBA fulfillment fees, storage fees, closing fees in some categories, and refund-related adjustments.
FBA storage fees are based on the space inventory occupies and can increase during peak periods or when inventory remains unsold for a long time.
Fees can be high because of oversized packaging, low selling price, expensive category referral rates, slow inventory turnover, or additional fulfillment services.
Reduce package size, improve inventory turnover, avoid long-term storage, reprice low-margin items, and compare FBA with merchant fulfillment where practical.
