• Amount - what the customer's card was charged (the original charge on the platform).
• Net - what actually landed in your Stripe balance for this payment.
• Fee - Amount minus Net: everything deducted in between, i.e. the card processing fee plus Sprwt's application/processing fees for that payment.
• Refunded - the total already refunded back to the card for this payment (only shown when greater than zero).

The large number in the page header is the Net amount. Because the Fee is calculated as a difference, it already includes every fee type for that payment; the per-fee-type totals are on Stripe > Fees (Service Fees Report).
