   What makes me wonder, this happens just for some transactions

   Take a look at this transaction: 20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6

   As you can see inputs/outputs fee is: 0.001 BTC

   In bitcoin-core gettransaction

   bitcoin-cli gettransaction "20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6" true
   

   Returns this result:

   Array
   (
       [amount] => -105.21509845
       [fee] => 105.11519845

       [blockhash] => 0000000000004caf7faef44b3cd20424b04e8044a8d323064e1fca6864b96cb9

                       [account] => 
                       [address] => 2N2QxAHtCMMDpxTxuNNNHvDh4burprspWPN
                       [category] => send
                       [amount] => -0.1625
                       [vout] => 0
                       [fee] => 105.11519845
                       [abandoned] => 
                   )
   
               [1] => Array
                   (
                       [involvesWatchonly] => 1
                       [account] => 
                       [address] => 2MtuDKij5ueE4C9D5wjA3Ft9bkjMJByxr4d
                       [category] => send
                       [amount] => -105.05259845
                       [vout] => 1

                       [abandoned] => 
                   )
   
           )
   

   But with this transaction everything is fine:

   20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6

   bitcoin-cli gettransaction "20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6" true
   

   Result:

       [fee] => -0.001
       [confirmations] => 136

                       [involvesWatchonly] => 1
                       [account] => 
                       [address] => mxKPZ2rnev5odtFTqS273946YgQfY7H6E5
                       [category] => send
                       [amount] => -0.0001
                       [vout] => 0
                       [fee] => -0.001
                       [abandoned] => 
                   )
   
               [1] => Array
                   (
                       [involvesWatchonly] => 1
                       [account] => 
                       [address] => 2NG1QAAFsM71L7YwVxkjSeMbKYpW6KFURXs
                       [category] => send
                       [amount] => -1.0489
                       [vout] => 1
                       [fee] => -0.001
                       [abandoned] => 
                   )
   
           )
   

   to get the fee of that type of transactions we could do:

   105.21509845 (amount) - 105.11519845(fee) = 0.001

   But why bitcoin core doesn’t do it and why it’s only for some transactions?

   Can you post the result of “validateaddress 2MtuDKij5ueE4C9D5wjA3Ft9bkjMJByxr4d” on this wallet? Specifially, the ismine, iswatchonly, and account fields?

   I don’t think it is possible for the wallet to calculate the fee of non-wallet transactions. Closing for now.

   Well, this looks like a duplicate of #14136. So closing for that reason and retracting my previous reason to close.
