user5134: Given a transaction where an NFT reached its final destination after a sale, how can I derive the cost of the NFT? For example, if I search for an asset on cardanoscan.io, the assets involved confuse me: RAVE and ROCKET.
Is there a calculation I can do on the inputs and outputs to derive the exact cost of the transaction? Not just the transaction fee but the cost of the token? Or do I have it conceptually wrong?
Thanks in advance for any insight!


user7146: If you can identify the size of the tx (bytes) you could utilise the fee calculation formula given the protocol parameters at the time of submission. (This might be tricky, but it is possible if you were inclined enough to find out a fairly accurate ball-park fee)

Cardano's fee structure is quite simple. Fees are constructed around two constants (a and b). The formula for calculating minimal fees for a transaction (tx) is a * size(tx) + b, where: a/b are protocol parameters.
