</script>This FBA profit tool is for Amazon sellers checking whether a product still works after referral fees, FBA fulfillment fees, inbound shipping, storage, other costs, and product cost. Enter your sale price and cost assumptions to compare revenue, net profit, profit margin, ROI, and the sale price needed to hit a target margin. It is useful before ordering inventory, changing a listing, adding PPC cost, or deciding whether a thinner-margin product is still worth restocking. Unlike a simple revenue calculator, the page focuses on seller unit economics: what you invest, what Amazon deducts, what profit remains, and whether the product has room for ads, returns, and cash-flow risk.
A product sells for $29.99, costs $17.00, has $1.50 inbound shipping, a $5.10 FBA fee, and a 15% referral fee. The calculator shows roughly how much net profit, margin, and ROI remain after Amazon fees.
If your target margin is 25%, use the reverse calculator to find the minimum sale price before ordering inventory or changing your listing price.

This Amazon FBA profit calculator gives you a complete picture of unit economics in under 30 seconds. Here's how to use each field accurately.
Use your current Amazon listing price, or the price you're planning to set. If you're testing different price points, change this field and the results update instantly. This is the amount the buyer pays — not including Amazon's promotional discounts.
This is your landed cost per unit — what you paid the supplier plus any inspection fees. Do not include inbound shipping to Amazon here; that goes in the next field. If you sourced from Alibaba, use the per-unit cost at your factory quote quantity.
This is the cost to ship each unit from your supplier (or your prep center) to Amazon's fulfillment center. For sea freight from China, divide your total freight cost by the number of units in the shipment. Typical range: $0.50–$2.50 per unit depending on weight and shipping method.
Find your FBA fee estimate in Amazon Seller Central under 'FBA Revenue Calculator', or check the FBA fee schedule. The fee depends on your product's size tier (determined by dimensions and weight). Example configured rates: Small Standard (<1 lb) = $3.15, Large Standard (<1 lb) = $3.58, Large Standard (1–2 lb) = $5.06. Seller Central quotes usually already include the 3.5% fuel surcharge — leave the checkbox ticked in that case, or untick it to have the calculator add the surcharge for you.
Choose your product category and the calculator applies Amazon's tiered referral rates automatically — for example, Clothing is 5% up to $15, 10% to $20, and 17% above, while Electronics Accessories charge 15% on the first $100 and 8% on the rest. A $0.30 per-item minimum applies. If your subcategory uses a different rate, open Advanced options and edit the referral % directly — that manual value overrides the category. Verify your exact rate in Seller Central under 'Selling on Amazon fees'.
The colored progress bar tells you your margin health at a glance. Green = Healthy (≥15% margin). Orange/yellow = Thin margin (5–15%). Red = Loss or near-zero. The badge in the top right updates automatically: Loss / Thin margin / Healthy / Strong margin (≥25%).
Enter your target margin percentage in the Reverse Calculator below the results. The Amazon FBA Calculator instantly tells you the minimum sale price you'd need to charge. This is the most useful feature for repricing decisions — start with your cost structure, not your competitor's price.
Amazon usually takes a referral fee plus an FBA fulfillment fee before you subtract product cost, inbound shipping, storage, ads, or other costs. Referral fees run 8–17% depending on category and price — some categories switch rates at price thresholds (clothing is 5% under $15 but 17% over $20), and a $0.30 per-item minimum applies. Fulfillment fees depend on product size and weight, plus a 3.5% fuel surcharge unless your quoted fee already includes it. For a product selling at $29.99 with a 15% referral fee and $5.10 FBA fee, Amazon fees are about $9.60 before your own costs.
Amazon's Revenue Calculator can use marketplace-specific data and Amazon's own assumptions. This calculator is designed for quick planning: enter your sale price, product cost, inbound shipping, and FBA fee, then pick your category for tiered referral rates (or override with a custom referral %) and add storage, returns rate, and other costs to model profit, ROI, and target price before you make a sourcing or pricing decision.
Most experienced FBA sellers target a net profit margin of 20–30% after all fees. The 'Healthy' zone on this Amazon FBA profit calculator starts at 15% — below that, small fluctuations in ad spend, storage fees, or supplier costs can eliminate your profit margin. The 'Strong' margin zone is ≥25%, which gives you room to run PPC and absorb returns.
The easiest way: go to Seller Central → Inventory → select your product → Actions → 'View FBA fees'. Alternatively, use Amazon's 'Match Low Price' tool which shows fee previews. Fees are based on your product's size tier — measure the dimensions and weight of your packaged product (including all inserts and labels) to determine your tier. Once you find your fee, enter it in the Amazon FBA Calculator — and since Seller Central quotes usually include the 3.5% fuel surcharge, leave the surcharge checkbox ticked — to see your true per-unit profit.
Yes — use the 'Other cost per unit' field to add your average per-unit ad spend. Calculate this as: (Monthly PPC Spend) ÷ (Units Sold per Month). Many sellers forget PPC when calculating profitability, which leads to thinking a product is profitable when it's actually break-even or a loss. Always model your 'true' margin including typical ad spend.
