Here is the state of the mempool with respect to fees, you must figure out how many bytes your transaction is and include the appropriate fee based on this and your desired speed. https://jochen-hoenicke.de/queue/#BTC,6m,weight

Transactions require that the amount sent in outputs does not exceed the amount consumed by the inputs. The difference between the two is implicitly the transaction's fee, which can be claimed by the miner that accepts the transaction into a block.

Thus, if you construct a transaction which consumes more than you want to send, but don't explicitly add an output to make those coins actually go back to you, you're burning them as transaction fee.
