Why Amazon Sellers Need a Fee Alert Tool

Amazon FBA fees can change without notice. Storage fees escalate quarterly, fulfillment fees were hit with a 3.5% fuel surcharge in April 2026, and aged inventory surcharges kick in at 181 days. Without a monitoring system, sellers often discover these cost increases only when their profit margins have already eroded. A fee alert tool lets you set thresholds for each fee type and receive notifications before costs spiral out of control.

Common Amazon Fee Types to Monitor

• FBA Fulfillment Fees — $3.45-$12+ per unit depending on size tier and weight. Includes 3.5% fuel surcharge (April 2026).
• Referral Fees — 6-45% of selling price by category. Most categories charge 15%.
• Monthly Storage — $0.78-$2.40 per cubic foot depending on season and size tier.
• Aged Inventory Surcharge — $1.22-$7.90 per cubic foot for items stored 181+ days.
• Return Processing Fees — 20% of referral fee, capped at $5 per SKU.
• Inbound Placement Fees — $0-$0.98 per unit based on placement option.

How to Set Up FBA Fee Alerts

Use the tool above to create alert rules for your key fee categories. Set a monthly threshold for total fees, a per-SKU limit for fulfillment costs, and a storage duration alert at 150 days (before the 181-day surcharge kicks in). Review your fee trends weekly using the built-in charts to spot anomalies early. For a complete fee calculation, use our FBA Fees Calculator or the FBA Profit Calculator.
