How much profit do you actually keep per Amazon sale?
An Amazon calculator estimates your profit per unit after Amazon's referral fee, fulfillment costs, and your product cost are subtracted from your selling price. Enter your selling price, product cost, and category; choose FBA, FBM, or compare both. The calculator shows your profit per unit, profit margin, ROI, fee burden, break-even price, and a full fee breakdown, plus monthly and annual revenue and profit projections if you enter expected sales volume.

Note: Amazon fees are estimates and may vary by product category, selling price, fulfillment method, product size, weight, storage duration, marketplace, and Amazon fee updates. Sellers should verify final fees in Amazon Seller Central before pricing or launching a product.

How to use the Amazon fee calculator

Step 1: enter your selling price 

This is the price customers pay on Amazon. Enter the full amount, including any shipping you charge. Amazon referral fees are calculated on this total figure.

Step 2: add your product cost (COGS) 

Enter what you pay to source, manufacture, or buy one unit. This should not include Amazon fees.

Step 3: select your product category 

The calculator uses your category to estimate Amazon's referral fee rate. Electronics is estimated at 8% in this calculator, while many categories use 15%. Some categories have tiered rates based on price, so sellers should verify the final referral rate in Amazon Seller Central. The category you select determines the referral fee applied to your selling price.

Step 4: choose your fulfillment method 

Select FBA (Fulfillment by Amazon) or FBM (Fulfilled by Merchant), or compare both. FBA means Amazon stores and ships your inventory where fulfillment fees apply. FBM means you ship directly, and your own shipping costs apply instead.

Step 5: select a product size profile 

This helps the calculator estimate fulfillment costs without requiring you to know every Amazon fee table. Options run from small standard sizes through to large/bulky to oversized/heavy products.

Step 6: Select your Amazon selling plan

Choose Individual (USD $0.99/item), Professional (USD $39.99/month), or ignore the selling plan fee. This is optional; include it if you want the calculator to factor Amazon's selling plan cost into your per-unit profit estimate. 

Note: If Professional is selected, the calculator allocates the monthly fee across expected monthly units.

Step 7: enter expected monthly units 

Add your expected monthly sales volume to see monthly and annual revenue and profit projections. This moves you from per-unit economics to business-level planning.

Step 8: add optional inputs (for a more accurate estimate)

  • Advertising cost per unit
  • Storage cost per unit
  • Other variable costs
  • Additional package details: If you know your product’s length, width, height, and weight, add them to improve the storage cost estimate. Fulfillment fees still use the selected product size profile unless exact costs are added.

Step 9: read your results

The calculator leads with your best option (FBA or FBM) and profit per unit (what you keep after Amazon fees, fulfillment, and product cost).

Below that, Business Health shows profit margin, ROI, fee burden, and break-even price.

The Fee Breakdown lists each cost line individually. It also shows “Amazon referral fee + fulfillment fee” as a subtotal, followed by total cost per unit and net proceeds.

If you selected "Compare both," the FBA vs FBM comparison shows both scenarios side by side with a best option callout. If you entered monthly units, Business Projection shows monthly and annual revenue and profit.

What is an Amazon fee calculator

An Amazon profit calculator estimates your true profit per unit from selling on Amazon after accounting for referral fees, fulfillment costs, and product cost. It answers the question most sellers ask before listing a product: after Amazon takes its cut, how much do I actually keep?

The Amazon fee calculator is useful at two stages. 

Before launch, it tells you whether a product's current cost structure can support a viable margin at the price the market will bear. 

After launch, it helps you identify which cost levers, like product cost, fulfillment method, or ad spend, are compressing your margin the most.

This Amazon FBA revenue calculator covers referral fees, FBA fulfillment fees, FBM shipping costs, optional advertising and storage costs, selling plan fees, and the key metrics that follow: profit margin, ROI, fee burden, and break-even price.

What fees does Amazon charge sellers

Amazon sellers pay several layers of fees, and understanding each one is how you protect your margin.

Referral fees

The referral fee is Amazon's selling commission, paid on every sale, regardless of fulfillment method. It's calculated on the total sale price: item price plus shipping charges plus gift wrap charges, with sales tax excluded.

Rates vary significantly by category, covering everything from clothing & accessories and electronics to home & kitchen, beauty, grocery, toys, sports, books, furniture, and more. 

Many categories have a USD $0.30 minimum referral fee, but minimums vary by category. Sellers should check Amazon’s current fee schedule before pricing. When the percentage-based fee calculates to less than USD $0.30, you pay USD $0.30 instead.

Verify your category's current rate in Amazon Seller Central before pricing.

FBA fulfillment fees

If you use Fulfillment by Amazon, Amazon charges a per-unit fulfillment fee based on product size and weight. This fee covers picking, packing, shipping, and customer service for that order. This FBA revenue calculator uses product size profiles as estimates, not Amazon’s exact fulfillment fee table.

FBA fulfillment fees have an average increase of around USD $0.08 per unit for 2026, according to Amazon. The FBA calculator uses estimated FBA fee profiles by product size.

Note: Actual FBA fees depend on your product's exact dimensions, weight, category, and current Amazon fee schedules.

FBM shipping costs

With FBM, you ship orders yourself. There's no FBA fee, but you're covering the full cost of fulfillment. The Amazon FBM calculator estimates FBM shipping costs by product size. Your actual shipping cost will depend on your carrier, packaging, destination, and fulfillment setup.

Amazon selling plan fees

Amazon offers two selling plans. The Individual plan charges USD $0.99 per item sold. The Professional plan charges USD $39.99 per month flat, regardless of volume.

Optional costs: advertising, storage, and other variable costs

These aren't Amazon fees in the traditional sense, but they're real costs that compress margin for most sellers.

Advertising cost per unit: Amazon PPC costs money per click and per conversion. If you're running ads, divide your estimated monthly ad spend by your monthly units sold to get your advertising cost per unit.

Storage fees: FBA sellers pay monthly storage fees for inventory held in Amazon's fulfillment centers.

Other costs per unit: Prep fees, returns allowance, extra packaging, inspection costs, and labeling all add up. The Amazon revenue calculator's "other cost" field captures whatever variable cost your specific operation carries.

FBA vs. FBM: which one is right for your product

The right fulfillment method depends on your product size, shipping efficiency, and how much operational work you want to own.

FBA (Fulfillment by Amazon) means Amazon stores your inventory, picks and packs orders, ships to customers, and handles fulfillment-related customer service. You pay Amazon fulfillment fees and any applicable storage costs, but you hand off the operational work.

FBM (Fulfilled by Merchant) means you store inventory yourself, pack and ship every order, and manage the fulfillment experience end to end. You don't pay FBA fees, but your shipping costs and operational load replace them.

Neither is universally better.

  • FBA typically makes sense for standard-sized, fast-moving products where Amazon's fulfillment efficiency outweighs the fee.
  • FBM can improve margin for sellers with large or bulky products, high-volume shipments with efficient carrier contracts, or items with slow turnover that would rack up storage fees in an Amazon fulfillment center.

The "Compare Both" option in the Amazon Fulfillment calculator runs both scenarios side by side, showing FBA profit per unit, profit margin, Amazon referral + fulfillment comparison, plus profit per unit, profit margin, and total cost per unit. So you can see where the difference actually lands for your product.

How Amazon profit per unit is calculated

Revenue isn't profit. A USD $50 sale on Amazon is not USD $50 in your pocket; Amazon's fees and your fulfillment costs come out first.

Profit per unit = Selling price − product cost − Amazon referral fee − fulfillment cost − optional costs

For FBA, fulfillment cost means Amazon's fulfillment fee plus inbound shipping. For FBM, it's your own shipping cost. Optional costs (advertising, storage, prep, selling plan fee) reduce profit further depending on your setup.

What's left after all of that is what you actually keep per sale.

Amazon fee calculator: understanding the key output metrics

Profit margin

Profit margin shows what percentage of the selling price becomes actual profit:

Profit margin = Profit per unit ÷ Selling price × 100

ROI

ROI measures how efficiently your product cost converts into profit. Here’s how to calculate ROI for the Amazon FBA program calculator:

ROI = Profit per unit ÷ Product cost × 100

High ROI with a low margin can still mean a viable product. It depends on your capital cycle. Low ROI on high-priced inventory ties up cash inefficiently.

Fee burden

The fee burden shows what percentage of your selling price is consumed by Amazon referral fee + fulfillment fee. It does not include product cost, inbound shipping, selling plan, advertising, storage, or other optional costs.

Fee burden = (Amazon referral fee + fulfillment fee) ÷ Selling price × 100

For most standard FBA products, fee burden can consume a significant share of your selling price before product cost or ad spend enters the picture. If that number climbs too high, there's little room left for operating costs and margin by the time everything else is accounted for.

Break-even price

Break-even price is the minimum selling price required to avoid a loss:

Break-even price = Non-referral costs ÷ (1 − Referral fee rate)

If your break-even price is close to your current selling price, you have little room for price compression — whether from competitors, promotions, or Amazon's own pricing algorithms. The Amazon fee calculator surfaces this clearly so you can see how much pricing headroom you're working with.

How to reduce Amazon seller fees and improve your margin

The most reliable way to improve margin on Amazon is to address the cost layers you control instead of the ones Amazon sets.

Optimize your product dimensions and weight 

Package dimensions can help you understand storage impact. For exact FBA fulfillment tier changes, sellers should verify product dimensions and fees in Amazon Seller Central. Use the fulfillment cost calculator to model how storage, product cost, and fulfillment assumptions affect profit. Verify final FBA tier changes in Seller Central.

Compare FBA vs. FBM before committing to a fulfillment strategy 

FBA simplifies operations but adds fulfillment fees and storage costs. For large, slow-moving, or high-COGS products, FBM can deliver better per-unit economics if you have efficient shipping. Use the "Compare both" mode to see where the difference falls for your specific product.

Switch selling plans once volume justifies it 

If you're selling more than 40 units per month, the Professional plan (USD $39.99/month) saves money over the Individual plan (USD $0.99/unit). The selling plan toggle in the Amazon Seller Central calculator shows the per-unit impact of each option at your volume.

Factor ad cost into your margin model from day one 

Advertising cost per unit is one of the most commonly omitted inputs in Amazon margin calculations and one of the most significant. Model your realistic Amazon PPC cost per sale in the Amazon fee calculator before deciding on a selling price or COGS target.

Review product category assignment 

Some products qualify for more than one Amazon category, and referral fee rates differ. If there's a legitimate alternative category with a lower rate, the math is worth the effort. A 2–3 percentage point difference on a high-volume product compounds fast.

Before you commit to inventory, run the calculations using the Amazon fee calculator above. Until the margin makes sense, modify the selling price, product cost, fulfillment strategy, and advertising expenditure.

Once you've decided Amazon is the right channel, the next problem is operational: Amazon pays out on a two-week disbursement cycle, your inventory spend is continuous, and ad budgets need daily oversight. 

The majority of e-commerce companies lose money because of this disconnect between revenue and control. With integrated spend controls, real-time budget monitoring, and accounting interfaces, Aspire1 gives you corporate cards2 to ensure that your cash allocation is clean from the start.

Frequently asked questions

What is an Amazon fee calculator?

An Amazon fee calculator estimates your profit per unit after accounting for Amazon's referral fee, fulfillment costs (FBA or FBM), and your product cost. It helps sellers and ecommerce founders understand whether a product's pricing and cost structure can support a viable margin before they commit to inventory or a launch.

How do I calculate Amazon seller fees?

To calculate Amazon seller fees, start with your referral fee, which is your selling price multiplied by the category referral fee rate. Add FBA fulfillment fees (if using FBA) or your own shipping cost (if using FBM). Then subtract referral fees, fulfillment cost, product cost, and any optional costs (advertising, storage, prep) from your selling price to get profit per unit. The calculator above does this automatically once you enter your product details.

What is the difference between FBA and FBM fees?

FBA (Fulfillment by Amazon) fees include a per-unit fulfillment fee paid to Amazon for picking, packing, and shipping your orders, plus inbound shipping costs to get your inventory to Amazon's warehouse. FBM (Fulfilled by Merchant) replaces FBA fees with your own shipping cost — you manage and pay for fulfillment directly. The fee structures are different, but both reduce your profit per unit from the selling price.

What is the Amazon selling plan fee?

Amazon offers two selling plans. The Individual plan charges USD $0.99 per item sold — no monthly fee. The Professional plan charges USD $39.99 per month flat, regardless of how many items you sell. If you sell more than 40 items per month, the Professional plan is less expensive. The Professional plan includes additional selling tools and programs compared with the Individual plan. Access to specific features may depend on Amazon’s current eligibility requirements.

What is fee burden on Amazon?

Fee burden is the percentage of your selling price consumed by Amazon referral fee + fulfillment fee. It's calculated as: Amazon referral fee + fulfillment fee divided by selling price, multiplied by 100. For many FBA products, referral and fulfillment fees can take a meaningful share of the selling price. Use the calculator to check your product-specific fee burden before pricing.

What is Amazon break-even price?

Break-even price is the minimum selling price required to avoid losing money on a sale after all costs. The calculator estimates it using: non-referral costs divided by (1 minus the referral fee rate). If your current selling price is close to your break-even price, you have limited room to absorb price pressure, promotions, or cost increases.

What happens if I enter package dimensions?

If you add your product's length, width, height, and weight in the optional package details section, the calculator uses those to improve its storage cost estimate. Without dimensions, it falls back to your selected product size profile. If you're carrying FBA inventory for more than a few weeks, entering exact dimensions gives you a more realistic storage cost figure.
