Amazon FBA Fee Calculator

What this Amazon FBA calculator estimates

Amazon seller fees are not a single percentage. For most physical products sold through FBA, your economics combine a referral fee (category-based), an FBA fulfillment fee (size and weight), storage (time in fulfillment centers, often higher in peak months), and your own product cost plus optional ads, inbound, and returns. This page estimates those pieces so you can see approximate net profit, reverse-price to a target profit, compare FBA vs FBM, or isolate fees only.

Figures are illustrative planning estimates for common 2026-style US patterns, with simple regional multipliers for UK, Canada, Australia, and EU-style presets. They are not Amazon’s Fee Preview for a specific ASIN. Always confirm referral and fulfillment in Seller Central → Fee Preview before you commit to a buy or a list price.

How Amazon FBA fees typically break down

• Referral fee — Usually a percentage of the total sales price, with category rules and often a small minimum. Many categories cluster near 15%; electronics and some others differ; apparel and jewelry use tiered logic in this tool.
• FBA fulfillment — Charged per unit when Amazon picks, packs, and ships. Driven by size tier and shipping weight. Use the auto-estimate from tier and weight, then override with Fee Preview for live accuracy.
• Storage — Monthly charge based on volume and season. Peak periods can raise effective storage cost; the peak multiplier here is a planning switch, not a full cubic-foot inventory model.
• Other costs — Optional field for ads, inbound freight, prep, returns, or miscellaneous. Leaving it at zero understates true contribution margin if you run PPC.

How to use each mode

Profit — Enter item price, category, cost, FBA, and storage. Read net profit and margin. Change region to apply illustrative FBA scaling for non-US presets.

Reverse price — Enter the net profit you need. The solver estimates a minimum list price given referral tiers and fixed FBA/storage/other costs. Use it as a floor, then validate in Seller Central.

FBA vs FBM — Same price and referral logic; FBM sets FBA/storage to zero and subtracts your shipping and optional time cost. Useful when deciding whether convenience and conversion justify FBA.

Fees only — Shows Amazon-side fees without focusing on net after COGS. Helpful for fee-rate conversations or screenshots for planning docs.

Worked example (illustrative)

Suppose a large-standard item at $29.99, 15% referral category, $8.00 product cost, about $4.75 FBA, $0.50 storage, no ads. Referral is roughly $4.50; Amazon-side fees plus COGS can leave a modest net before advertising. Raise price, lower COGS, or reduce size/weight and the margin moves quickly. That sensitivity is why Fee Preview on the real ASIN matters more than any public calculator.

If reverse price says you need $34+ to clear an $8 net under your assumptions, treat that as a go/no-go signal for sourcing—not as a guarantee of rank or conversion at that price.

FBA vs FBM in plain terms

FBA trades higher per-unit fees and storage risk for Prime eligibility and less operational work. FBM can win on margin when shipping is cheap, volumes are low, or products are awkward for fulfillment centers. Compare both columns with honest FBM shipping and a realistic time cost if you pack orders yourself.

Regional presets

The region control applies simplified multipliers—primarily to estimated FBA—so non-US sellers can stress-test scenarios. It is not a full local rate card for every EU store or category. Referral structures and VAT handling differ by marketplace. Confirm on the marketplace you actually sell on.

What this tool does not include

• Age-of-inventory surcharges and long-term storage details
• Full dimensional-weight warehouse rules for every edge case
• Coupon, deal, or advertising attribution models
• Tax, VAT, or accounting treatment
• Buy Box probability or ranking forecasts

Professional workflow before you buy inventory

1. Estimate landed product cost including inbound.
2. Run Profit and Reverse modes with conservative FBA and storage.
3. Override FBA with Seller Central Fee Preview for the ASIN or a close comparable.
4. Stress-test peak storage and a non-zero ads line.
5. Compare FBA vs FBM if you can ship yourself.
6. Only then commit to a purchase order.

Accuracy and professional use

Serious sellers should treat any third-party calculator as a worksheet, not as a substitute for Amazon’s own fee schedule. Category placement, dangerous-goods rules, apparel size tiers, and inbound placement services can all change the live number. When two tools disagree, Seller Central wins.

Use this page to educate stakeholders, screen product ideas quickly, and document assumptions (COGS, ads, peak storage). Then lock the decision with Fee Preview screenshots stored in your product file.

Margins, ads, and contribution profit

Net profit after referral and FBA is not the same as profit after advertising. Many accounts spend a meaningful share of sales on sponsored products. Put a realistic ads amount in Other costs when you plan launches. A product that looks fine at zero ads can fail when ACOS is included.

Returns and customer service also erode margin. If your category has high return rates, model a returns allowance in other costs rather than assuming every unit sticks.
