Calculate Any Address Balance Using Bitcoinn RPC getrawtransaction
Bitcoin Core does not support querying an address balance.

What you can do is import the address as watch-only into your wallet (using the importaddress RPC), and completing a rescan of the blockchain. When you're finished, the wallet will treat that address as one of its own, and track payments to it, and include it in its balance. Of course, you won't be able to spend it without private key.
