Cost of goods is not the full cost
A product can look profitable if you only compare selling price to product cost. The real margin often changes after platform fees, payment fees, shipping supplies, shipping subsidies, returns, and advertising.
Good pricing starts with a full cost stack. If you sell through Etsy, Shopify, eBay, or paid ads, include those costs before deciding whether a product is worth selling.
Common selling costs
| Cost | Example | Pricing impact |
|---|---|---|
| Product cost | Unit cost or COGS | Base cost to recover |
| Payment fee | Stripe or PayPal processing | Variable plus fixed fee |
| Platform fee | Etsy, eBay, marketplace fee | Can be large by category |
| Shipping | Postage and supplies | Can erase margin on low-ticket items |
| Ad spend | Cost to acquire a buyer | Often the biggest swing factor |
Example: price after fees
A seller buys a product for $14 and wants a 40% net margin. They plan to sell through a platform with a 10% fee, a 3% payment fee, $0.30 fixed processing, $5 shipping support, and $4 average ad cost.
A $35 price may look strong before fees, but after platform fee, payment fee, shipping support, ad spend, and product cost, the real profit can be far lower than expected. The price may need to be raised, the ad cost reduced, or the product dropped.

Formula
The math behind the result
Real profit = price - product cost - shipping - payment fees - platform fees - ad cost.
Target price should be based on net margin after all selling costs, not only product cost.

FAQ
Common questions
Should platform fees be included in product pricing?
Yes. If the fee happens on every sale, it should be included before setting or approving a price.
How do I price products for Etsy or Shopify?
Use the same product cost and target margin, then model each platform fee and traffic cost separately.
What if competitors are cheaper?
Do not match a competitor price unless your cost structure can support it. Competing below real margin burns cash.
Should shipping be free?
Free shipping can improve conversion, but the cost still has to be built into the price or margin model.
