How to use the eBay Promoted Listings Calculator
- Enter the price, shipping and your costs.
- Enter the ad rate you plan to set.
- Press Calculate to compare profit with and without promotion.
Formula
Ad fee = sale total × ad rate
Break-even ad rate = profit without promotion ÷ sale total
Examples
- 50 item, free shipping, cost 18, postage 8, 5% ad rate, default rates: ad fee 2.50, profit with ads ≈ 14.30 vs 16.80 without; break-even ad rate 33.6%.
Frequently asked questions
Where do the default rates come from?
From eBay’s official selling fees pages for eBay.com, for most categories with no store subscription, checked on 27 October 2026. Some categories (for example certain clothing, collectibles, jewellery or business equipment) and store subscribers pay different rates, so change the fields to match your case.
What ad rate should I choose?
eBay suggests rates in Seller Hub based on similar listings. A higher rate can improve visibility but costs more of your margin; this calculator shows how much you can afford.
