How much is the PayPal fee for $100?

Excuse me, could you please clarify the PayPal fee structure for a transaction amount of $100? I'm trying to understand the exact cost associated with sending or receiving this amount through PayPal, and I'm hoping you could provide me with a concise and accurate answer. Is there a flat fee or is it a percentage of the total amount? Additionally, are there any other factors that could potentially affect the fee, such as the recipient's location or the type of transaction? Thank you for your assistance in this matter.
