Why Platform Choice Is a Margin Decision
Choosing between Shopify and Amazon is not about which platform is better — it is about which platform's fee structure leaves more money in your pocket after each sale. The answer depends on your product category, price point, and fulfilment method.
Shopify Fee Breakdown
Transaction and Payment Fees
Shopify charges a monthly subscription ($39/month on the Basic plan in 2026) plus a payment processing fee of approximately 2.9% + $0.30 per transaction when using Shopify Payments. If you use a third-party gateway, an additional 2% transaction fee applies.
What Shopify Does Not Charge
Shopify does not take a percentage of your sale price as a referral fee. This makes it significantly cheaper than Amazon for high-ticket items. A $200 product on Shopify costs roughly $6.10 in payment fees; the same product on Amazon would cost $30+ in referral and FBA fees.
Amazon Fee Breakdown
Referral Fees
Amazon charges a referral fee of 8–20% depending on category. Most consumer products fall in the 15% range. This fee is calculated on the total sale price including shipping.
FBA Fulfilment Fees
If using Fulfilment by Amazon, expect additional per-unit fees of $3–6 for standard-sized products, plus monthly storage fees. FBA fees vary by weight and dimensions.
The Hidden Cost: Returns
Amazon's return rate for most categories is 5–15%. Amazon absorbs the customer-facing cost, but sellers absorb the inventory loss. Model your return rate honestly in DropCalc — it is one of the input fields — to see the true impact on your margin.
Side-by-Side Comparison at Common Price Points
$50 Product
Shopify (Basic): ~$1.75 in payment fees = 96.5% of sale price retained before COGS.
Amazon (15% referral + $3.50 FBA): ~$11 in fees = 78% retained.
$150 Product
Shopify: ~$4.65 in fees = 96.9% retained.
Amazon: ~$26 in fees = 82.7% retained.
The gap widens at higher price points, which is why Shopify becomes increasingly attractive for products above $80.
Which Should You Choose?
Choose Amazon if your product benefits from search intent traffic and you can absorb the higher fees in your margin. Choose Shopify if you have (or plan to build) an audience through paid social or SEO and your product price is above $60.
