Amazon FBA now consumes 35–55% of revenue once referral fees, fulfilment, storage, and ads are stacked — Shopify's all-in cost sits around 3.2%. The gap doesn't mean Shopify always wins: it depends entirely on whether your acquisition cost beats Amazon's built-in traffic. Map your real per-order cost before you commit to either.

Sell a $50 item on Amazon FBA and you net roughly $28 after fees. Sell it on Shopify and you net roughly $35. That's the finding from nventory.io's 2026 marketplace fee comparison, published March 2026 — and it's not a rounding error. At 1,000 orders a month, that $7 gap is $7,000 in margin walking out the door. The headline numbers explain why. Amazon's referral fees run 8–15% depending on category. Add FBA fulfilment ($3–$8 per unit), storage ($0.78 per cubic foot per month for standard, higher in Q4), and the advertising spend most sellers need just to stay visible, and total Amazon costs land between 35–55% of revenue, according to data from Agentis's 2026 benchmark report. Shopify's all-in cost — monthly plan plus Shopify Payments processing — sits around 3.2% of revenue when you use their native gateway. That's not a like-for-like comparison, and Shopify knows it. Amazon brings the traffic. You don't. On Shopify, you own the customer relationship, the data, and the storefront — but you're also paying for every click that arrives. Meta ads, Google Shopping, influencer deals: those costs don't appear in Shopify's fee table, but they absolutely appear in your P&L. The real question isn't which platform charges less. It's which platform leaves more money in your account after you've paid to acquire the customer. Last year, most sellers defaulted to Amazon because the traffic was easy. This year, with Amazon ad CPCs climbing and FBA storage surcharges back for peak season, the maths has shifted enough to force a harder look.
What does the Amazon fee structure actually cost a seller doing $30,000/month?#
Take a US-based seller moving $30,000/month in mid-range home goods on Amazon — average order value $45, roughly 667 units. Here's what the fee stack looks like in 2026: Referral fee at 15%: $4,500. FBA fulfilment at $5.50/unit average: $3,668. Storage fees (assuming 200 cubic feet at $0.78): $156. Advertising spend to maintain page-one visibility — realistically 10–15% of revenue for a competitive category — call it $3,750 at 12.5%. Total outgoing before COGS: $12,074. That's 40.2% of gross revenue gone before you've touched product cost or shipping inbound to FBA. Now run the same $30,000 on Shopify. Monthly plan at $105 (Advanced). Shopify Payments processing at 2.4% plus $0.30 per transaction: approximately $920. That's $1,025 in platform fees — 3.4% of revenue. But add a realistic paid acquisition budget. If your blended customer acquisition cost is $12 and your repeat purchase rate is low, you're spending $8,000+ to drive that volume. Suddenly you're at 30% of revenue in costs — better than Amazon, but not by the margin the fee table implies. The crossover point matters. If your email list, organic search, or social following drives more than 40% of your Shopify orders, the platform wins decisively. If you're starting cold with zero owned audience, Amazon's traffic subsidy is worth more than it costs — at least until your ad spend on Amazon itself eats the arbitrage. A seller doing $30k/month with strong repeat buyers and a 4,000-person email list will net materially more on Shopify. A new seller with no list, no SEO, and a generic product will struggle to match Amazon's economics until year two.
How do you calculate your true cost of selling on Amazon vs Shopify?#
Three moves operators are running right now to get a clean number: **1. Build a per-SKU cost stack, not a blended average.** Amazon fees vary by category — electronics referral fees run 8%, jewellery hits 20%. A seller with a mixed catalogue averaging 15% is masking products that are unprofitable at current prices. Pull your referral fee rate by ASIN, add the exact FBA fee from Amazon's fee calculator (updated March 2026), and layer in your actual advertising cost per unit sold — not your total ad spend as a percentage of revenue, which hides category-level variation. **2. Price your Shopify acquisition cost honestly.** The most common mistake: Shopify sellers count platform fees but not CAC. Pull your Meta and Google ad spend for the last 90 days, divide by new customer orders, and add that number to every first-order margin calculation. If your repeat purchase rate is above 3x, your blended CAC amortises and Shopify's economics improve sharply over 12 months. Track cohort LTV, not single-order margin. **3. Run the dual-channel test before committing.** The most profitable operators in 2026 aren't choosing — they're using Amazon FBA for discovery and top-of-funnel volume, then redirecting repeat buyers to a Shopify DTC store via email and packaging inserts. Amazon's terms of service prohibit direct solicitation inside the platform, but a 'register your purchase for warranty' insert is legal and converts at 8–12% to owned channels according to multiple seller reports this year. That redirect turns Amazon's traffic into Shopify's economics over time.
How AskBiz calculates your real platform margin before you make the wrong call#
A founder running $22,000/month across both Amazon and Shopify types this into AskBiz: *'Which channel has the better margin after fees and ad spend this quarter?'* AskBiz pulls live data from their connected Shopify store, Amazon Seller Central via CSV upload, and their Stripe account. It surfaces this: Amazon channel — gross revenue $14,200, total fees and FBA costs $5,538 (39%), ad spend $1,704 (12%), net contribution margin 49%. Shopify channel — gross revenue $7,800, platform fees $271 (3.5%), paid acquisition spend $1,950 (25%), net contribution margin 71.5%. The answer isn't 'Shopify is cheaper.' It's 'your Shopify margin is 22.5 percentage points higher this quarter because your email channel is driving 58% of Shopify orders at near-zero acquisition cost — but if that drops, the gap closes fast.' That's the decision the fee table can't give you. AskBiz's margin analysis connects your actual ad account spend to your actual channel revenue, so the comparison reflects your business — not a benchmark built on someone else's CAC. You can then run a what-if: *'What happens to my Amazon margin if I cut ad spend by 20%?'* and see the volume impact modelled against your current conversion rate before you touch the budget.
What are the warning signs your Amazon fees are compressing your margins right now?#
Four signals worth checking this week: **Your ACoS is above 25% on core SKUs.** Above that threshold in most mid-margin categories, advertising alone is eating the referral fee savings from higher-volume tiers. Pull your ACoS by ASIN, not blended. **FBA storage fees have crept above $0.50/unit/month.** That's the threshold where slow-moving inventory starts destroying the economics of FBA vs self-fulfilment. Amazon raised its aged inventory surcharges in early 2026 — items over 181 days now trigger higher rates. **Your Shopify conversion rate has dropped below 1.8%.** If paid traffic is arriving but not converting, your effective CAC is rising without appearing in your fee line. Check your last 30-day Shopify analytics against the prior period. **You haven't recategorised products since 2024.** Amazon updates its fee schedule by category. Some sellers are still paying 2024 rates they've never audited — check the current referral fee table against every active ASIN.
Your action plan before Friday#
**Before Friday:** Pull your last 90 days of Amazon ad spend and divide it by total Amazon orders. Add that number to your blended FBA fee rate. If the combined figure exceeds 45% of your Amazon revenue, you have a margin problem that platform growth won't fix — you need a channel mix decision, not a bigger ad budget. **Set up once:** Connect both your Shopify and Amazon data to a single dashboard that tracks net contribution margin by channel, not gross revenue. If you're using AskBiz, link your Shopify store and upload your Amazon transaction report — the margin comparison runs automatically. **Track monthly:** Net contribution margin per channel, after fees and acquisition cost. Not GMV. Not orders. Not conversion rate in isolation. The one number that tells you which platform is actually working is what's left after you've paid to sell and paid to fulfil. Set a floor — 35% net contribution is a reasonable minimum for physical goods in 2026. If either channel drops below it, you need to know within the month, not at year-end.

Amazon FBA total costs in 2026 typically consume 35–55% of revenue. That breaks down as: referral fees of 8–15% by category, FBA fulfilment at $3–$8 per unit, storage fees from $0.78 per cubic foot per month, plus advertising spend of 10–15% for most competitive categories. Best operators audit by ASIN, not blended average.
Is Shopify cheaper than Amazon for sellers in 2026?
Shopify's platform fees are around 3.2% all-in using Shopify Payments — far lower than Amazon's 35–55% of revenue. But Shopify doesn't supply traffic. Add a realistic paid acquisition cost and the gap narrows significantly. Shopify wins when you have an owned audience; Amazon wins when you're starting cold with no list.
How much does Amazon charge per sale in 2026?
Amazon charges a referral fee of 8–15% per sale depending on category, plus FBA fulfilment of $3–$8 per unit and storage fees if you use their warehouse network. Before advertising, that's typically 25–35% of revenue. Add a 10–15% ad spend and total costs reach 35–55% of gross revenue for most sellers.
What is the real cost of selling on Shopify vs Amazon?
Shopify's real cost is platform fees (3.2% all-in) plus your customer acquisition cost. Amazon's real cost is referral fees, FBA fulfilment, storage, and advertising — totalling 35–55% of revenue. The platforms are only comparable when you include acquisition spend on both sides. Sellers with strong owned audiences consistently net more on Shopify.
