Per Order fees:
Etsy transaction fees are 6.5%
Payment processing fees are 3% plus 25 cents per order
These fees are applied to the price of the order plus shipping
Advertising Fees
Offsite ad fees are 15% of the order IF applicable. If you have never sold more than $10K in a 12 month period you can opt out of offsite ad fees. Certain locations can opt out of offsite ads. I think its UK and Europe - someone will chime in with the exact locations.
Etsy ad fees are charged per click up to whatever you have budgeted. You can budget $0. You can specify which listings to include in offsite ads.
Listing fees
Etsy listing fees are 20 cents per listing - good for 4 months. Then listings expire or renew based on your settings. Listings with multiple quantities renew each time an item or items from that listing are purchased.
Other fees
The buyer pays taxes or VAT on the order. That amount is added to the value of the order and shown in what the buyer pays but the taxes go to the state or country.
If you've signed up for Etsy Plus, those fees are charged to your account monthly.
Summary
Etsy's fee structure is what it is. The mainstream and logical advice is to factor the fees into the prices. Think of the fees as a payment for a service.
Your finance section provides detail on all the fees charged to your account and all the revenue you earn.
