On average, eBay takes between 10% and 15.55% of the final selling price in fees. This percentage can increase if you're selling internationally or using promoted listings. It's important to factor in all of these fees when pricing your items to ensure that you're making a profit after all fees are taken into account.

If you are registered on ebay.com, you receive 250 zero insertion fee listings per month. This means you won't be charged insertion fees for these listings. You'll only pay insertion fees after you've used up those listings.

Amazon is the better choice if you're looking to reach a large audience and sell a wide variety of products. eBay may be a better fit if you're looking for lower fees and more control over your business.
