Price any SKU and watch your profit, margin and ROI move in real time.
Pick a category, set your price, and Marginely applies Amazon's 2026 referral fee (including tiered categories) plus the FBA fulfillment fee — then shows what you actually keep. Drag the price slider to find the number that hits your margin target. No login.
Amazon takes two main cuts on every FBA sale: a referral fee (a category-based commission on the sale price) and an FBA fulfillment fee (a flat per-unit charge for pick, pack and ship, based on size and weight). Referral fees were frozen for 2026 — unchanged since January 2024 — while FBA fulfillment fees rose by an average of about $0.08 per unit from January 15, 2026.
The 2026 changes that aren't in this calculator
Two 2026 shifts hit margin outside the referral + FBA math above. Amazon ended US prep and labeling on January 1, 2026, so non-compliant inbound shipments now carry a defect fee of roughly $0.32–$5.72 per unit (up from $0.02–$0.07). And since March 10, 2025, lost or damaged stock is reimbursed at manufacturing cost, not retail — a $50 item that cost $15 to source pays back $15. Factor both in before trusting a thin margin.
Referral fees are tiered in some categories
Most categories charge a flat 15%, but several are tiered, meaning the rate changes with price. Clothing is the clearest example: items at or below $15 pay 5%, the $15–$20 band pays 10%, and above $20 pays 17%. Grocery charges 8% under $15 and 15% above. This calculator applies the correct tier automatically when you change the price — which is exactly why the rate note next to the price field updates as you type.
The $0.30 minimum referral fee
Most categories carry a $0.30 minimum referral fee per unit. On sub-$4 items the minimum, not the percentage, sets your fee — so a cheap accessory can be quietly unprofitable even at a "low" rate. The calculator enforces this floor.
Use the price slider to defend your margin
Drag the price slider and watch margin and ROI move. When a competitor undercuts you or Amazon nudges fulfillment fees, this is the fastest way to find the lowest price you can run while protecting your target margin. Bookmark it — most sellers re-check this every time they reprice.
2026 referral fees by category (quick reference)
15% (flat): Home & Kitchen, Beauty (over $10), Toys, Pet, Sports, Office, Tools, Garden, Baby, Health
Electronics: 8% (consumer electronics); Electronics Accessories 15% up to $100, 8% on the portion above
Referral fees are calculated on the full transaction value (item price plus any shipping/gift-wrap you charge), not just the item price. Verify your exact category in Seller Central — listing in the wrong browse node is a common, costly error.
Margin vs ROI — which should you target?
Margin (profit ÷ sale price) tells you how much of each sale you keep — useful for pricing and PPC headroom. ROI (profit ÷ cost) tells you how hard your cash is working — useful for deciding what to reorder. A high-margin product with slow turnover can have worse ROI than a thin-margin product that sells fast. Watch both; reorder on ROI, price on margin.
What this calculator doesn't include
Monthly storage, long-term storage surcharges, inbound placement fees, returns processing, and advertising are not included by default — add them via "Other cost / unit" if you want a fully loaded number. FBA fulfillment fees here are estimated from weight as a starting point; pull the exact figure from your listing's fee preview in Seller Central for precision. Figures are estimates, not financial advice.
Frequently asked questions
Are 2026 Amazon referral fees higher than 2025?
No — referral fees are frozen for 2026, unchanged since January 2024. What rose in 2026 is the FBA fulfillment fee (about $0.08 per unit on average from January 15, 2026) plus new inbound defect fees after Amazon ended free US prep on January 1, 2026. The referral percentage itself hasn't moved.
Does this calculator include FBA storage fees?
No. It covers the referral fee and the per-unit FBA fulfillment fee — the two charges on every sale. Monthly storage, long-term storage surcharges, returns processing and advertising aren't included; add them under "Other cost / unit" for a fully loaded margin.
Why is my real FBA fee different from the number here?
The FBA fulfillment fee here is estimated from weight as a starting point. Your actual fee depends on the exact size tier and dimensional weight Amazon measures at check-in. Pull the precise figure from your listing's fee preview in Seller Central and enter it under "Other cost / unit" for an exact result.
What referral fee applies if my item is under $15?
It depends on the category. Most stay at 15%, but tiered categories are cheaper at low prices — clothing is 5% at or under $15, grocery 8% under $15, beauty 8% at or under $10. Watch the $0.30 per-unit minimum, though: on sub-$4 items the minimum, not the percentage, sets your fee.
Worked example: one SKU, every line of the math
Run one illustrative SKU through the full chain the calculator applies. A $29.99 Home & Kitchen item: referral at 15% is $4.50. Say your inputs are a $7.00 landed cost, a $5.50 FBA fulfillment fee (yours comes from your size tier — enter the real one from Seller Central, or let the weight estimate stand in), and $1.00 per unit of PPC in "Other cost". Net: $29.99 − $4.50 − $5.50 − $7.00 − $1.00 = $11.99 per unit — a 40% margin and 171% ROI on the $7 you put at risk. That's the healthy version. Now watch how fast it thins: a $3 price drop to $26.99 takes the referral fee down only 45 cents but takes net profit down $2.55 — because every dollar of price cut is a dollar of profit cut minus only your referral rate. Price moves hit profit roughly 85 cents on the dollar in a 15% category; cost moves hit it dollar for dollar. That asymmetry is why the slider matters more than any single estimate.
Finding your floor price before a price war finds it for you
The number worth knowing before you ever get undercut is your break-even price — where net profit is exactly zero. The algebra the calculator is doing for you: break-even = (landed cost + FBA fee + other costs) ÷ (1 − referral rate). For the SKU above: ($7.00 + $5.50 + $1.00) ÷ 0.85 ≈ $15.88. Anything below that price loses money on every unit before storage and returns. Two practical uses: set a repricer floor at break-even plus your minimum acceptable margin, and check the floor against your category's tier boundaries — in tiered categories, dropping price through a breakpoint changes the divisor itself, so a floor computed at 17% may be wrong at 10%. Drag the slider down until net hits zero and you'll see your true floor, tier changes included, without doing any algebra.
Individual vs Professional: the $0.99 question
The plan toggle above adds $0.99 per sale on the Individual plan. The Professional plan replaces that per-sale charge with a flat subscription of $39.99 a month — so the crossover is about 41 units: below roughly 40 sales a month the Individual plan's pay-per-sale is cheaper, above it the subscription wins, and the gap widens with every additional unit. Two caveats push the crossover lower in practice: Professional is also the gate for features that affect revenue (Buy Box eligibility on most categories, advertising, restricted-category applications), and the $0.99 applies per unit sold, not per order-day — a good launch week can quietly cost more than the subscription it was avoiding. If you're modeling a real business rather than a test listing, model Professional.
Pricing with the whole stack, not just this page
This calculator isolates the two fees every FBA sale always pays — referral and fulfillment — because they're the ones that scale with your pricing decision. A durable price also has to carry the rest of the stack: monthly and aged-inventory storage on slow movers, returns (both the refund-processing cost and the fraction of returned units you can't resell), advertising as a percentage of sales rather than a fixed line, and the 2026 inbound-defect exposure ($0.32–$5.72 per unit) if your prep process isn't airtight. A workable habit: price to your target margin in this calculator, then subtract 3–5 points as the stack allowance and check the result still clears your floor. If a SKU only works at a 10% margin with zero allowance, it doesn't work.
More questions sellers ask
When should I switch from Individual to Professional?
Around 40 sales a month on pure fees — the $0.99 per-sale charge crosses the $39.99 monthly subscription at about 41 units. In practice, switch earlier: Professional also gates Buy Box eligibility, advertising, and restricted-category applications, all of which move revenue, not just fees. Use the plan toggle above to see the per-unit effect at your volume.
Does the $0.30 minimum referral fee apply in every category?
Most categories, yes — and it binds exactly where percentages feel safest. At 15%, the minimum takes over below $2.00; in an 8% category it governs everything under $3.75. If you sell low-priced consumables or accessories, margin them on $0.30 flat, not the headline rate — the calculator enforces the floor automatically.
Is the referral fee charged on my shipping charge too?
Yes — the fee base is the full transaction value: item price plus any shipping or gift wrap you charge the buyer. FBA listings mostly ship free for the buyer so this bites FBM sellers hardest: if you charge $4.99 shipping, the referral percentage applies to it. Model FBM prices on the delivered total, not the item price.
How do I put my PPC spend into this calculator?
Convert it to a per-unit number and enter it in "Other cost": total ad spend for the SKU ÷ total units sold in the same period (all units, not just ad-attributed ones — organic sales carry the ad budget too). A SKU spending $300 a month and selling 200 units carries $1.50 per unit. Re-check it monthly; ad cost per unit drifts more than any fee on this page.
