What percentage does eBay take?

I'm curious, could you please elaborate on the commission structure that eBay employs? Specifically, what percentage of the final sale price does eBay typically take from sellers on their platform? It's essential for me to understand the cost implications of using eBay as a sales channel for my products or services. Is there a standard fee across all categories, or does it vary depending on the item being sold? Additionally, are there any additional fees or charges that sellers should be aware of? Your insights into this matter would be greatly appreciated.
