Fee assumptions and calculation method
Review the supported US fee presets, rounding, tax assumptions and excluded charges before using a seller profit estimate.
Check the preset before relying on a number
This release models US domestic USD transactions, one item per order. The eBay preset is for most categories without a Store; it does not cover special-category rates, Store discounts, international sales or seller penalties. Etsy uses a US bank-account processing rate. Canada, the UK and EU need different presets and are not represented by changing the currency symbol. Additional fees and expenses can be entered as dollar costs, but this does not make an unsupported account fully modeled.
Date and fee sources
Preset rates were checked on 6 October 2026. The eBay most-category model uses 13.6% through $7,500 of sale value and 2.35% above, plus a $0.30 order fee through $10 or $0.40 above. Etsy uses a 6.5% transaction fee, US payment processing of 3% plus $0.25, and a manually chosen Offsite Ads rate capped at $100 per attributed order. Listing fees are entered separately. Recheck the linked official schedules before relying on an estimate.
Rounding and boundaries
Modeled fee lines are rounded to the nearest cent. eBay’s fixed per-order charge changes above a $10 fee-base total; the percentage tier changes above $7,500. Etsy Offsite Ads are capped separately. The price search checks cent-priced scenarios around those boundaries. Differences from a real invoice can remain because of allocation, timing or rounding.
Keep fee maintenance separate from SEO
The site must be reviewed when marketplace fee schedules change. Pages show their last checked date and direct links to official schedules. A date does not mean rates update automatically. The calculators are independent tools and are not endorsed by eBay or Etsy.
Other primary references
US Etsy payment processing is documented in the Etsy Payments Policy at etsy.com/legal/etsy-payments/. Platform names identify the fee presets; they do not indicate a partnership. Use your own account schedule for any unsupported account, region or category.
