Median Fee Rate shows the median fee rate paid by Bitcoin transactions on a given day, in sat/vB. Half of transactions paid a lower fee rate and half paid a higher one, so it is the canonical baseline for the typical competitive price of block space.
A rising median fee rate means the typical transaction is paying more per unit of block space. A falling series means the clearing environment is easing. It is most useful with Fee Rate (P90), Fee Rate (P99), and Median Transaction Fee, which separates block-space pricing from raw fee paid.
The key distinction is unit choice. A raw fee in satoshis depends partly on transaction size, while fee rate expresses the price of block space itself. That makes median fee rate structurally different from per-transaction fee metrics.
