Hi,
PayPal fees are not considered as part of the order cost by default. You need to configure the settings in order to add the PayPal fees to the order costs.
Go to Orders tab, Extra Costs: From Meta in the Meta keys add PayPal Transaction Fee. You will need to recalculate the order’s cost and profit after you change these settings.
The Extra Costs: Payment Gateways tab is for adding any additional costs that you may have for payment gateways. For example, some payment gateways charge a fixed fee per order + a percentage of total order value. Such extra fees can be added to the order costs using this section.
