How can I add processing fees to Strip payment platform?

I am creating a form selling a product. I have integrated this with our Stripe account.  Is there a way to add the credit card processing fees to the payment that the customer will pay?

Unfortunately, there is not a way to add an extra cost through the payment settings, you can only add shipping cost and tax to your forms, if you would like to add an extra costs you would need to add a product, indicate what's being charged, set the product required and select the product by default: 

Hope this helps.
