fees calculator
A $50 product on Amazon can cost $7.50+ in fees before shipping — 15% or more of your price. See your real profit per sale on any platform.
The sticker price is not your revenue
Marketplaces take a cut at every step: referral fees (5–15%), payment processing (2.9% + $0.30), platform fees (monthly or per listing), and shipping. On a $50 product these easily reach $8–15.
Your net profit per sale is price minus all fees, minus product cost and shipping. Run the calculator below before pricing anything.
Referral / commission
5–15% of the sale price, category-dependent. Amazon charges ~15% on most categories.
Payment processing
~2.9% + $0.30 per transaction via Stripe/PayPal or the platform processor.
Platform & shipping
Monthly plans ($0–39), listing fees, and shipping which you set or subsidize.
The margin rule : If your product costs less than ~40% of the selling price, marketplace fees + shipping will eat most of your profit. Price with the full fee stack in mind.
How to price for real profit
Five steps from cost to profitable price.
-
1
List every fee
Referral %, payment fee, platform fee, shipping, returns. Total them as a share of price.
-
2
Add product cost
Goods + packaging + your time. Underestimating cost is the #1 profit killer.
-
3
Set shipping honestly
Free shipping attracts buyers but it is a cost you pay. Build it into the price.
-
4
Compare platforms
Shopify (your own store) vs Amazon (built-in traffic) vs Etsy (craft buyers). Fees and traffic differ.
-
5
Re-price by category
Raise prices or cut costs until net margin hits 20%+. The calculator shows the gap.

Estimates only, based on your inputs.
What fits your store
Match the platform to your product and audience.
Craft seller
Etsy’s built-in buyers justify the 6.5% fee. Price your time in — crafts are labor-heavy.
Your own brand
Shopify gives control and lower per-sale fees, but you pay for traffic via ads.
Volume seller
Amazon FBA handles fulfillment but takes 15% + storage. High volume can still pay.
Small local shop
Etsy or Shopify Plus-lite beat marketplace fees for low volume with loyal customers.
Wholesale / own site
WooCommerce on your hosting cuts fees to payment processing only.
High returns category
Clothing and electronics eat margin in returns. Add 10–20% to the price to absorb it.
