Bitcoin Network Fees

Bitcoin transaction fees are priced in satoshis per virtual byte (sat/vB), not as a flat amount. Your total fee is the rate multiplied by your transaction’s size, so a simple one-input send is cheap while a transaction that consolidates many small inputs costs more at the same rate. Miners prioritise the highest-rate transactions, which is why a higher sat/vB buys faster confirmation.

The tiers above estimate the rate needed for different confirmation targets: Fastest aims for the next block, while Economy is for transfers you’re happy to leave pending until the network quietens. When the mempool is congested all tiers rise together; when it’s empty even the fastest tier can drop to a few sat/vB. We label the current rate by color so congestion is obvious at a glance — but the exact number is always shown as text, never color alone.

This page tracks the Bitcoin network. Ethereum gas uses a different fee market (gwei + priority tips) and a keyed data source, so it is intentionally out of scope here rather than shown with an unreliable feed.
