You are right, The trouble in here finding the input values!! How does blockchain.info and other chains get these info?

I assume blockchain.info and similar sites use their own databases of information rather than querying it from a node every time

Yeah I guess they update each new transaction to their database.

To find the fee of the transaction, you need to know the value of the inputs and outputs and find the difference between those two values.

Unfortunately this is much more difficult for receiving transactions, because by default bitcoin core only holds the information for transactions which are related to your wallet, not all transactions (this can be enabled with `txindex=1` argument).

What this means is that, to find the fee for a receive transaction, you can call `getrawtransaction "txid" true` with the txid you obtain from `listtransactions`. The last argument, `true` is set to make the output "verbose" so that it includes more information about the transaction than just the hex encoded transaction itself. It will return a JSON object with `vin` and `vout` arrays which you can iterate over. You can simply sum the output values. The trouble is finding the input values. Input values are not given in transactions, so you must look them up individually.
