Hi @tonygao ,
Thanks for reaching out!
Kindly note that the WooCommerce Stripe Payment Gateway plugin serves as a bridge between your site and the Stripe payment processing platform and doesn’t have any influence on the fees calculated.
You can see more on the fees in Stripes documentation here:
On the other hand, please keep in mind that this forum is specifically for support related to the WooCommerce core plugin.
If you need any further help related to the WooCommerce Stripe Payment Gateway plugin, we kindly ask that you create a new topic in the WooCommerce Stripe Payment Gateway forum.
Although, I do believe that the Stripe support team is in a better position to help you understand how those fees are calculated.
Hope this helps!
