To calculate Amazon FBA fees and profit: (1) Start with your selling price. (2) Calculate referral fee by multiplying selling price by category percentage (typically 8-20%, most are 15%). (3) Determine FBA fulfillment fee based on size tier and weight—ranges from $3.06 for small items to $50+ for large items. (4) Add monthly storage fees ($0.78/cubic foot Jan-Sep, $2.40/cubic foot Oct-Dec). (5) Subtract all fees plus your product cost from selling price to get net profit. Example: $29.99 selling price - $4.50 referral (15%) - $5.77 FBA fee - $10 product cost = $9.72 profit.

Low-Price FBA is Amazon's program for products priced under $10, offering $0.77 lower fulfillment fees compared to standard FBA rates while maintaining Prime shipping eligibility. For example, a Small Standard item (4-8 oz) costs $2.38 with Low-Price FBA versus $3.15 standard FBA—a $0.77 savings per unit. This applies across all size tiers from Small Standard to Extra-Large. The savings make lower-priced items significantly more profitable and competitive. To qualify: (1) Product must be priced at $10 or less. (2) It automatically applies to eligible items. (3) All other fees (referral, storage) remain unchanged. (4) Prime shipping still included. Low-Price FBA is ideal for: consumable products, add-on items, clearance inventory, and high-velocity low-margin products. The $0.77 savings can turn unprofitable items profitable or allow you to price more competitively.

Amazon referral fees are calculated as a percentage of your selling price and vary by product category. The formula is: Referral Fee = Selling Price × Category Percentage. Common rates: Beauty & Personal Care: 8% (15% over $10), Consumer Electronics: 8%, Automotive: 12%, Most categories (Toys, Sports, Home): 15%, Apparel & Accessories: 17%, Jewelry: 20% (minimum $2). Example: A $50 apparel item incurs $50 × 17% = $8.50 referral fee. A $50 electronics item incurs $50 × 8% = $4.00 referral fee. Important: Referral fees are based on total sale price including shipping (for non-FBA), but exclude tax. Minimum referral fee is $0.30 for most categories, $2.00 for jewelry. Some categories have tiered structures—Baby Products are 8% under $10, 15% over $10. Always check your specific category in Seller Central for exact rates.

Amazon peak season fees are surcharges added to FBA fulfillment fees during the busy holiday period from October 15, 2025, to January 14, 2026. These fees help manage increased fulfillment center demand during Black Friday, Cyber Monday, and Christmas shopping. Peak fees by size tier: Small Standard: +$0.19, Large Standard: +$0.24, Large Bulky: +$0.58, Extra-Large (0-50 lb): +$0.77, Extra-Large (50-70 lb): +$1.15, Extra-Large (70+ lb): +$1.73. Example: A Large Standard item normally costs $5.77 FBA fee, but costs $6.01 during peak season (+$0.24). Important notes: Fees apply based on shipment date, not order date. If ordered October 14 but shipped October 15, peak fees apply. Plan pricing strategies accordingly—either absorb the cost or slightly increase prices. Consider pre-positioning inventory in September to avoid inbound delays during peak season.

To estimate your break-even price (minimum selling price to cover all costs without loss), use this formula: Break-Even Price = (Product Cost + FBA Fee + Other Costs) / (1 - Referral Fee %). Example: Product Cost $10, FBA Fee $5, Other Costs $2 (PPC, storage), Category 15% referral. Break-Even = ($10 + $5 + $2) / (1 - 0.15) = $17 / 0.85 = $20.00. This means you must sell for at least $20 to avoid losing money. Why divide by (1 - referral %)? Because referral fee is calculated ON the selling price, not added to costs. At $20 price: Referral = $3 (15%), leaving $17 to cover $17 in costs. Use our Break-Even Analysis calculator above for quick calculations. Add 20-40% margin above break-even for profitable pricing. Consider: competitor pricing, perceived value, and price elasticity when setting final price.

FBA fees and referral fees are distinct charges: Referral Fees are Amazon's commission for using their marketplace—charged on ALL sales whether FBA or FBM (Fulfilled by Merchant). Calculated as percentage of selling price (8-20% depending on category). Example: 15% of $30 = $4.50 referral fee. FBA Fees are fulfillment service charges—only for sellers using Fulfillment by Amazon. Covers: picking, packing, shipping, customer service, and returns. Based on size tier and weight, not selling price. Example: Large Standard 2 lb item = $5.77 FBA fee regardless of whether you sell it for $20 or $50. Combined example: $30 product in 15% category, 2 lb Large Standard: Referral = $4.50 (15% of price), FBA = $5.77 (size-based), Total fees = $10.27, leaving $19.73 before product cost. Both fees are unavoidable if using FBA and must be factored into pricing strategy.

Amazon FBA storage fees are charged monthly based on cubic feet your inventory occupies in fulfillment centers. Standard storage rates 2025: January-September: $0.78 per cubic foot per month, October-December: $2.40 per cubic foot per month (3x higher for holiday season). Example: 100 cubic feet stored for 3 months Jan-Mar = 100 × 3 × $0.78 = $234. Same during Q4 = 100 × 3 × $2.40 = $720. Long-term storage fees: Aged inventory aged 271-365 days: $0.15 per unit per month minimum. Aged inventory over 365 days: $6.90 per cubic foot or $0.15 per unit per month (whichever is greater). To minimize storage costs: Maintain lean inventory (2-3 months supply), Use sales velocity to optimize reorder points, Remove slow-moving inventory before hitting long-term thresholds, Consider FBM for slow-moving items. Storage is often overlooked but can significantly erode profits, especially for large, slow-moving items.

A good profit margin for Amazon FBA products is 20-40% net profit margin (after all fees and costs). Industry benchmarks: Minimum viable: 15-20%—covers costs but leaves little buffer for PPC increases or price competition. Good: 20-30%—provides healthy profit while remaining competitive. Most experienced sellers target this range. Excellent: 30-40%—strong margin allowing for aggressive marketing and price resilience. Premium/luxury: 40%+—possible with unique, branded, or premium products. Calculate your margin: (Net Profit / Selling Price) × 100. Example: $7 profit on $30 product = 23.3% margin (good). Factors affecting margins: Product category (electronics lower, jewelry higher), Competition level (high competition = lower margins), Product differentiation (unique = higher margins), Brand strength (established brands command premium). Start with 30% target when selecting products—this accounts for unexpected costs (returns, damage, increased PPC) and provides cushion for promotions or sales.

To calculate monthly Amazon FBA revenue: (1) Determine daily units sold (check Business Reports in Seller Central for historical data or estimate based on listing rank and niche). (2) Calculate gross revenue: Daily Units × Selling Price × 30 days. (3) Calculate net revenue: Gross Revenue - (Total Fees × Units) - (Product Cost × Units). Formula: Monthly Net Revenue = (Units/Day × 30) × (Price - Product Cost - All Fees). Example: Selling yoga mats at $29.99, Product Cost $10, Total Fees $10.27, Selling 10 units/day. Gross: 10 × $29.99 × 30 = $8,997/month. Net: 10 × 30 × ($29.99 - $10 - $10.27) = 300 × $9.72 = $2,916/month net profit. Use our Revenue Calculator above for instant calculations. Consider: Seasonal variations (Q4 typically 30-50% higher), Advertising costs (usually 10-20% of revenue), Returns and refunds (typically 2-5%). Track actual performance monthly and adjust strategies accordingly.

Amazon FBA size tiers are determined by dimensional weight (longest side + median side + shortest side) and actual weight. Size tier definitions: Small Standard: (1) 15 × 12 × 0.75 inches or smaller, AND (2) 16 oz or less. Example: phone cases, small books. Large Standard: (1) 18 × 14 × 8 inches or smaller, AND (2) 20 lb or less. Example: apparel, most home goods, small electronics. Large Bulky: (1) 59 × 33 × 33 inches or smaller, AND (2) 50 lb or less. Example: vacuum cleaners, large cookware. Extra-Large 0-50 lb: Exceeds Large Bulky dimensions but under 50 lb. Extra-Large 50+ lb: Over 50 lb up to 150 lb. Important: Measurements include ALL packaging Amazon will receive. Pack efficiently to avoid jumping size tiers—even 0.1 lb over threshold triggers next tier's higher fees. A 16.1 oz item pays Large Standard rates ($3.68+) vs Small Standard ($3.06-3.65). Weigh and measure products IN shipping boxes before sending to Amazon.

FBA vs FBM fee comparison depends on your shipping costs and volume. FBA advantages: Built-in Prime eligibility (massive conversion boost—Prime members spend 2-3x more), Amazon handles customer service and returns, Typically cheaper per-unit shipping due to Amazon's economies of scale, Buy Box eligibility increases, Time savings (focus on sourcing/marketing vs fulfillment). FBA costs: Referral fee (same as FBM) + FBA fulfillment ($3-50+ depending on size) + Storage ($0.78-2.40/cubic foot/month). FBM costs: Referral fee + Your shipping cost + Your packing labor + Your storage + Customer service time. Break-even analysis: For small, lightweight items (under 1 lb), FBA often wins—your shipping would cost $4-8 vs $3-5 FBA. For large, heavy items (over 5 lb), FBM might be cheaper if you have good shipping rates. However, FBA's Prime conversion boost often outweighs slightly higher fees. Most sellers find FBA more profitable overall despite higher fees due to increased sales velocity.
