What Is a Good Amazon FBA Profit Margin?
Most experienced FBA sellers target a net profit margin of 15–30% after all Amazon fees and COGS. For context:
- Under 10% margin: Too thin — any PPC ad spend or return rate wipes profit
- 10–20% margin: Acceptable for high-volume, low-competition products
- 20–30% margin: Good — sustainable business with room for advertising
- 30%+ margin: Excellent — strong differentiated product or private label with moat
Frequently Asked Questions
What are Amazon FBA fees in 2026?
In 2026, Amazon FBA fees consist of three main charges: a referral fee (typically 15% of the sale price for most categories), a per-unit fulfillment fee ($3.11–$9.79+ depending on product size and weight), and monthly inventory storage fees ($0.78/cubic foot January–September, $2.40/cubic foot October–December). Amazon added a 3.5% fuel and logistics surcharge to all fulfillment fees starting April 17, 2026.
How do I calculate my Amazon FBA profit?
Net Profit = Sale Price − Referral Fee − FBA Fulfillment Fee − Storage Fee − Cost of Goods. For example, selling a product for $25 with a $4.01 fulfillment fee, 15% referral fee ($3.75), $0.50 storage, and $8 COGS: $25 − $3.75 − $4.01 − $0.50 − $8 = $8.74 net profit per unit (35% margin).
What is the Amazon referral fee?
The referral fee is a percentage of the total sale price (including shipping) that Amazon charges for each item sold. It varies by category: 15% for most categories, 8% for consumer electronics, 17% for clothing and accessories, and 6% for computers. The referral fee is the same whether you use FBA or fulfill orders yourself (FBM).
What size tier should I use in the FBA calculator?
Amazon classifies products into size tiers based on dimensions and weight after packaging. Small standard items weigh under 1 lb and have dimensions under 15×12×0.75 inches. Large standard items weigh 1–20 lbs. Measure your packaged product (including all packaging material) to select the correct tier, as choosing the wrong tier will give inaccurate fee estimates.
Is Amazon FBA still profitable in 2026?
Yes — Amazon FBA remains profitable in 2026, but requires careful product selection and pricing strategy. The average successful FBA seller earns 20–30% net margins on well-chosen private label products. Key success factors are finding products with a low referral fee category, high price point relative to fulfillment fees, low competition, and defensible differentiation. Products priced under $15 are increasingly difficult to profit from due to fixed fulfillment fee impact.
