What Is a “Fee Rate” (Sat/vb) and How Is It Calculated?

The fee rate is a measure of transaction cost efficiency, calculated as the total transaction fee paid divided by the transaction's virtual size in bytes (vB). It is typically expressed in satoshis per virtual byte (sat/vB).

Miners use this metric to rank transactions, prioritizing those with a higher fee rate to maximize the total fee revenue within a block's weight limit.
