Shopify vs Amazon FBA: which keeps more profit per order in 2026?
Short answer
Shopify keeps more of each order — roughly 92% of revenue after platform and payment fees, versus about 62% on Amazon FBA. Amazon wins on demand: you pay a far higher take rate but skip the customer-acquisition cost that sinks most Shopify stores.
Option A
Shopify
Your own store, your own traffic, your own customer list.
Strengths
- Platform take is ~2.9% + $0.30 processing plus a flat monthly plan
- You own the customer email and can remarket for free
- Full control of branding, bundling, and post-purchase upsell
- Repeat-purchase economics compound — CAC is paid once
Trade-offs
- You must buy every visitor: blended CAC of $18–$45 is normal
- Conversion rate averages 1.4–2.2% versus Amazon's 10–15%
- Fulfilment, returns, and support are your problem
Option B
Amazon FBA
Sell inside Amazon's marketplace with Amazon handling storage and shipping.
Strengths
- Enormous built-in purchase intent — no traffic to buy
- Prime badge lifts conversion to 10–15%
- Fulfilment, returns, and customer service are handled
- You can be profitable from month one with no ad stack
Trade-offs
- 15% referral fee plus $3.50–$8.50 FBA fulfilment per unit
- Storage, long-term storage, and removal fees eat slow movers
- You never get the customer's email — no owned remarketing
- Listing hijacking, suspensions, and fee changes are outside your control

Badge marks which option wins that row: A = Shopify, B = Amazon FBA.
Shopify wins the moment your repeat-purchase rate clears about 25%.
On a single transaction Amazon usually nets more, because Shopify's CAC eats the fee advantage: a $40 order nets $24.60 on Shopify before a $22 CAC, versus $14.80 on Amazon with no CAC. But CAC is paid once. If 30% of Shopify buyers order again within a year, blended lifetime contribution rises to about $32 per acquired customer against Amazon's $14.80 per order with weak repeat attribution. Consumables and refill products cross over fast; one-time-purchase gadgets often never do.
Worked example: A $40 supplement, 1,000 units/month, both channels
- COGS + inbound freight: $11.00 per unit on both channels
- Amazon: referral 15% = $6.00, FBA fulfilment = $5.40, storage/returns ≈ $1.10
- Amazon contribution = $40 − $11.00 − $12.50 = $16.50 → $16,500/month
- Shopify: processing $1.46, shipping + pick/pack $7.20, plan amortized $0.30
- Shopify pre-CAC contribution = $40 − $11.00 − $8.96 = $20.04
- Blended CAC on new customers (65% of orders) = $24 × 650 = $15,600
- Shopify contribution = (1,000 × $20.04) − $15,600 = $4,440/month
Amazon wins month one by $12,060. Give Shopify a 32% annual repeat rate and the same cohort re-orders 1.6× with zero CAC, closing the gap within roughly 11 months and passing it afterwards.
The verdict
Choose Shopify
Pick Shopify if your product is consumable, brandable, or high-margin enough to fund paid acquisition.
Choose Amazon FBA
Pick Amazon FBA if your product is a searched commodity with thin differentiation and you need cash flow now.
Or run both
Most durable brands run both: Amazon for discovery volume, Shopify for margin, bundles, and the email list.
Frequently asked questions
What is Amazon's true all-in fee percentage?
For a typical $30–$50 private-label product it lands at 30–38% of revenue once you include the 15% referral fee, FBA fulfilment, storage, returns processing, and PPC spend.
Can you sell the same product on both?
Yes, and price parity matters: Amazon's fair-pricing policy can suppress your Buy Box if your Shopify price is materially lower after shipping.
Which is better for a new brand with no audience?
Amazon, for cash flow. Use it to validate demand and fund the Shopify build rather than burning capital on ads into an unproven product.
Methodology
Fee assumptions use published Amazon US referral and FBA fulfilment rate cards for standard-size items in 2026 plus Shopify Basic plan and Shopify Payments US rates. Conversion and CAC ranges are ecommerce-industry medians; verify your own category rates before modelling.
