Amazon FBA

With FBA, the seller still needs to handle the business side of the product.

The seller is generally responsible for:

• Choosing products

• Sourcing inventory

• Paying suppliers

• Creating listings

• Pricing

• Sending inventory to Amazon

• Advertising

• Inventory planning

• Monitoring profitability

• Managing the seller account

Amazon then handles major fulfillment functions for FBA inventory:

• Storage

• Picking

• Packing

• Shipping to customers

• Customer service

• Returns

This can remove a large amount of logistics work, but it introduces fulfillment and storage fees.

Amazon sellers can also use Fulfilled by Merchant, or FBM.

Wholesale sellers purchase existing branded products from authorized distributors or brands and resell them.

The seller may compete on an existing Amazon listing.

Potential advantages:

• Existing customer demand

• No need to create a new consumer brand

• Easier demand validation

Challenges include:

• Supplier approval

• Brand restrictions

• Buy Box competition

• Lower margins

• Minimum order quantities

Wholesale economics can be more predictable than launching a completely new product, but competition can compress margins.

Retail arbitrage involves purchasing discounted products from physical stores and reselling them on Amazon.

For example:

Retail clearance price: $10 Amazon selling price: $30

The seller calculates whether enough profit remains after all Amazon fees.

Advantages:

• Low initial product quantities possible

• Products can be tested individually

• Lower supplier commitment

Disadvantages:

• Difficult to scale consistently

• Inventory availability changes

• Brand and category restrictions

• Time spent sourcing products

Online arbitrage is similar to retail arbitrage, but inventory is purchased from online retailers.

The seller searches for products that can be purchased at a lower price elsewhere and profitably resold on Amazon.

Scaling generally requires:

• Better sourcing

• Faster analysis

• More working capital

• Inventory management

Amazon currently offers two primary U.S. selling plans.

Amazon positions the Individual plan for sellers generally selling fewer than 40 products per month.

The Professional plan is generally intended for higher-volume sellers and provides access to additional tools such as:

• Advertising

• Bulk listing

• Detailed reports

• Brand-related tools

• Additional seller programs

A serious private-label business will usually require the Professional plan.

Amazon charges a referral fee when a product sells.

The exact percentage depends on the product category.

Amazon states that most categories generally fall between:

8% and 15%

Some categories have different percentages or pricing tiers.

The referral fee is normally calculated using the total sales price.

For example:

Selling price: $30 Referral rate: 15%

Referral fee:

$30 × 15% = $4.50

This happens before product, fulfillment, advertising, and inventory costs are considered.

FBA charges a per-unit fulfillment fee.

This covers major fulfillment functions including:

• Picking

• Packing

• Shipping

• Customer service

• Returns processing

The amount depends heavily on:

• Product dimensions

• Shipping weight

• Size tier

• Apparel vs non-apparel classification

Amazon's currently published non-apparel examples include:

Amazon increased U.S. FBA fees in 2026 by an average of approximately:

$0.08 per unit sold

The changes generally took effect on January 15, 2026.

Amazon stated there were no entirely new FBA fee types introduced for 2026, but existing fees were adjusted.

Sellers should always use the current Revenue Calculator or Seller Central fee tools instead of relying permanently on static historical fee tables.

Amazon charges monthly storage fees based on the volume occupied by inventory inside its fulfillment network.

Amazon's published standard-size schedule includes:

The fourth quarter is therefore significantly more expensive for stored inventory.

Additional storage-related charges can apply depending on factors such as:

• Inventory age

• Inventory level

• Dangerous goods

• Storage utilization

Keeping too much inventory inside FBA can materially reduce profit.

Inventory that sells slowly creates multiple problems.

Cash remains tied up in products while storage fees continue.

A product may initially appear profitable but become weak if inventory remains in Amazon's fulfillment centers for long periods.

Track:

• Inventory age

• Units sold per day

• Weeks of cover

• Reorder lead time

Do not treat Amazon warehouses as unlimited inexpensive long-term storage.

The seller pays to move inventory into Amazon's fulfillment network.

This is separate from the FBA fee Amazon charges when the product is sold to a customer.

Possible inbound costs include:

• Supplier-to-Amazon freight

• Domestic carrier

• Amazon partnered carrier

• International freight

• Customs

• Duties

• Prep

• Labeling

Inbound transportation must be included in landed cost.

Amazon may also charge an inbound placement service fee depending on how inventory is distributed into its fulfillment network.

Sellers can generally receive different shipment-placement options.

Examples include:

• Minimal shipment splits

• Partial shipment splits

• Amazon-optimized shipment splits

Sending inventory to fewer locations may create higher placement fees because Amazon redistributes the goods through its network.

Amazon stated that 2026 inbound placement fees increased by approximately:

$0.05 per unit on average

Depending on the shipment option, the seller may be able to reduce or avoid some placement charges by sending inventory to multiple Amazon locations.

The exact fee is shown while creating the inbound shipment.

Landed cost is the real cost of getting one unit ready for sale inside Amazon's system.

It can include:

Product manufacturing

• Packaging

• Inspection

• International freight

• Duties

• Domestic transportation

• Prep

• Labeling

• Inbound freight

• Inbound placement = Landed cost

Do not use factory price alone when evaluating a product.

For example:

Supplier price: $6

After freight, customs, prep, and inbound shipping:

Actual landed cost: $8.50

Using $6 in the profit calculation would materially overstate the product's margin.

Assume a non-apparel product sells for:

$30

Example unit economics:

Estimated contribution margin:

$8.40 ÷ $30 = 28%

This is before:

• Returns

• Refund losses

• Seller subscription

• Software

• Employees

• Taxes

• Unexpected fees

If advertising cost rises from $4 to $8 per sale:

Remaining contribution falls to:

$4.40

The exact same product can therefore move from attractive to weak economics without changing its retail price.

Amazon Seller Central may show large revenue numbers.

Revenue does not include the seller's complete expense structure.

For example:

Monthly sales: $50,000

Possible costs:

$50,000 revenue can therefore result in approximately $6,500 before tax in this hypothetical example.

The business should be evaluated using profit and cash flow, not sales screenshots.

Amazon-seller survey data can provide context, but it should not be treated as FBA-only performance.

Jungle Scout's published seller research found that among surveyed small and midsize Amazon sellers:

• 57% reported profit margins above 10%

• 28% reported profit margins above 20%

• 13% reported that they were not yet profitable

These figures include broader Amazon seller populations and different business models.

They do not mean a new FBA seller should expect those margins.

FBA startup cost varies dramatically by model.

Retail arbitrage can start with relatively little inventory.

Private label typically requires substantially more capital.

Jungle Scout's 2024 survey of Amazon sellers, brands, and businesses found:

• 25% started with less than $1,000

• 64% started with less than $5,000

• 17% reported spending more than $10,000

These numbers include multiple Amazon business models and should not be interpreted as the minimum required for private-label FBA.

A realistic small private-label launch might include:

This is not a universal industry requirement.

Some products require substantially more because of:

• Higher MOQ

• Larger product size

• Expensive tooling

• Freight

• Compliance

• Packaging

Unlike the earlier IncomeWiki setup tables, this cost estimate intentionally excludes items such as an existing computer or free software because they do not represent meaningful new startup cash requirements.

Before placing a large supplier order, purchase product samples.

Compare:

• Material

• Durability

• Color

• Packaging

• Dimensions

• Functionality

• Manufacturing quality

Do not choose a supplier based solely on the lowest quote.

A bad first batch can create:

• Refunds

• Poor reviews

• Inventory losses

• Listing problems

MOQ means minimum order quantity.

A supplier might require:

500 units × $5 = $2,500

before freight and other costs.

Lower MOQ reduces inventory risk but may increase unit cost.

Higher MOQ can reduce unit cost but creates larger:

• Cash requirement

• Inventory risk

• Storage risk

The cheapest unit price is not always the best purchasing decision.

Before sourcing a product, evaluate:

• Demand

• Competition

• Price

• Size

• Weight

• Referral fee

• FBA fee

• Advertising competition

• Review concentration

• Brand dominance

• Seasonal demand

• Product restrictions

Avoid selecting products only because they appear in "best products to sell" lists.

Once an opportunity becomes widely publicized, competition can increase rapidly.

FBA strongly rewards efficient products.

A small lightweight product can have:

• Lower fulfillment fee

• Lower inbound freight

• Lower storage cost

A bulky product creates the opposite.

Two products with the same $30 selling price can produce completely different margins because of size and weight.

Always enter realistic dimensions and weight into the Amazon Revenue Calculator before purchasing inventory.

Amazon restricts or requires approval for certain:

• Categories

• Brands

• Products

Restrictions can depend on:

• Seller history

• Marketplace

• Product type

• Compliance requirements

Check eligibility before purchasing inventory.

Do not assume a product can be sold simply because another seller currently lists it.

Some products may require regulatory or safety documentation.

Examples can include:

• Electronics

• Children's products

• Cosmetics

• Food

• Supplements

• Batteries

• Medical-related products

Compliance requirements vary by product and market.

Products with complicated compliance requirements may be inappropriate for a first launch.

Possible supplier sources include:

• Domestic manufacturers

• Overseas manufacturers

• Wholesalers

• Distributors

Evaluate:

• Price

• MOQ

• Lead time

• Communication

• Quality

• Certifications

• Packaging

• Production capacity

For larger orders, inspection can reduce the risk of discovering defects after inventory reaches Amazon.

International sourcing introduces additional costs.

Possible expenses include:

• Ocean freight

• Air freight

• Customs broker

• Duties

• Tariffs

• Inspection

• Port charges

• Domestic transportation

Freight costs can change rapidly.

Always update landed-cost calculations before placing a reorder.

An Amazon product listing commonly includes:

• Title

• Images

• Bullet points

• Description

• Variations

• Product attributes

• Price

• Search terms

A strong listing should clearly explain:

• What the product is

• Who it is for

• Major benefits

• Important specifications

Do not make unsupported product claims.

Product images can directly affect conversion.

Useful images may include:

• Main product image

• Product features

• Dimensions

• Product in use

• Packaging

• Comparison

• Detail shots

Follow Amazon's current image requirements.

Eligible brands can use A+ Content to add enhanced visual content to product detail pages.

It can include:

• Additional images

• Comparison modules

• Brand story

• Product features

A+ Content improves presentation but cannot rescue a product with weak demand or poor economics.

Brand Registry provides additional brand-management and protection tools for eligible brands.

Trademark requirements can apply.

Private-label sellers may eventually use Brand Registry to access:

• Brand tools

• A+ Content

• Additional protection features

Do not register a trademark only because a course says it is mandatory before testing any product.

The timing depends on the brand strategy.

Amazon Ads are an important traffic source for many competitive products.

Sponsored Products can appear in search results and product pages.

The seller typically pays per click.

For example:

Ad spend: $1,000 Sales attributed to ads: $4,000

ACOS:

$1,000 ÷ $4,000 = 25%

A 25% ACOS is not automatically profitable.

If the product only has 20% margin before ads, a 25% ACOS may lose money.

Advertising Cost of Sales:

Ad spend ÷ Ad-attributed sales × 100

Example:

$500 ads $2,000 attributed sales

ACOS = 25%

The acceptable ACOS depends on the product's margin.

Total Advertising Cost of Sales compares advertising spend to total revenue.

Ad spend ÷ Total sales × 100

It can help show whether advertising is contributing to broader organic sales or whether the business remains heavily dependent on paid traffic.

Break-even ACOS is approximately the margin available before advertising.

For example:

Selling price: $30 All non-ad expenses: $22

Pre-ad contribution:

$8

$8 ÷ $30 = 26.7%

An ACOS materially above 26.7% would lose money on the first-order economics in this simplified example.

A basic private-label launch may involve:

• Inventory received

• Listing activated

• Advertising started

• Search terms monitored

• Conversion reviewed

• Price tested

• Inventory tracked

Avoid assuming launch sales represent stable long-term demand.

A temporary promotion or high advertising spend can create sales that disappear once the campaign changes.

FBA requires balancing two expensive problems.

Example:

Average sales: 10 units/day Supplier and delivery lead time: 60 days Safety stock: 200 units

Reorder point:

10 × 60 + 200 = 800 units

Waiting until only 100 units remain would almost guarantee a stockout in this example.

FBA is inventory intensive.

Cash moves through a cycle:

Cash → Supplier inventory → Freight → Amazon inventory → Customer sale → Amazon payout → Reorder

A profitable business can still experience a cash shortage if it needs to reorder before previous inventory has generated enough available cash.

Growth often requires more working capital, not less.

Amazon handles FBA customer returns, but returns still affect seller economics.

A returned product may:

• Return to sellable inventory

• Become unsellable

• Require removal

• Create refund costs

Products with high return rates can look attractive based on gross sales but produce poor net economics.

Track returns by SKU.

Inventory that cannot be sold may need to be:

• Returned to the seller

• Liquidated

• Disposed of

Fees can apply.

This is another reason to avoid ordering excessive quantities before demand is proven.

Amazon provides a free Revenue Calculator for estimating product economics.

It can compare:

• FBA

• Seller fulfillment

The seller can input or adjust:

• Product

• Price

• Dimensions

• Weight

• Shipping

• Costs

The output remains an estimate.

Actual fees can differ, so sellers should also review actual Seller Central charges after launch.

The useful minimum setup for Amazon FBA is not a list of free software.

For a private-label seller, the real requirements are:

A reasonable small private-label launch can therefore require roughly:

$2,500–$7,000+

The number can be much higher for expensive, large, or regulated products.

Retail or online arbitrage can start with less because inventory can be purchased in smaller quantities.

The product should remain profitable after all meaningful costs are included.
