Question 1

How are Amazon FBA fees calculated?

Accepted Answer

Amazon FBA fees have two main components: (1) Fulfillment fee: charged per unit based on size and weight ($3.22 for small standard, $5.42 for large standard, $9.73+ for oversized), (2) Referral fee: 15% of the total selling price for most categories (varies 6–45% by category). Additional fees: monthly storage ($0.87/cubic ft Jan–Sep, $2.40 Oct–Dec), long-term storage for items over 365 days.

Question 2

What is the minimum profit margin for Amazon FBA?

Accepted Answer

Most successful Amazon FBA sellers target a minimum 25–30% profit margin after all fees. Below 20% leaves insufficient buffer for advertising (Amazon PPC typically costs 15–25% of sales in early phases), inventory risk, and return costs. The rule of thumb: if your product costs 3× your landed cost (1/3 product cost, 1/3 Amazon fees, 1/3 profit), your margins are healthy.

Question 3

What Amazon FBA costs are not included in this calculator?

Accepted Answer

This calculator covers FBA fulfillment and referral fees only. Not included: monthly inventory storage fees ($0.87–$2.40/cubic ft), Amazon PPC advertising (15–35% of sales for new products), prep/inspection services ($0.50–$1.50/unit), inbound shipping to Amazon warehouse, return processing fees, and removal order fees. Factor these into your true landed cost and margin analysis.

Question 4

Is Amazon FBA profitable in 2025?

Accepted Answer

Yes, but margins have compressed significantly. In 2019, sellers commonly achieved 40–50% margins; today 25–35% is more typical after fee increases. Profitable FBA niches in 2025: private label products in sub-categories with low competition, supplement/health products (high margins), packs and bundles (higher perceived value), and brand-registered products with strong reviews. Arbitrage has become increasingly difficult.

Question 5

How do I find products with good FBA margins?

Accepted Answer

Use the 3× cost rule: your selling price should be at least 3× your landed cost. Research tools (Jungle Scout, Helium 10) show estimated sales volume and competition. Filter for: monthly sales $10K+, review count under 500, selling price $20–$80 (sweet spot for impulse purchases and manageable FBA fees), and a product cost you can land for under 30% of selling price.
