A protocol-determined per-gas component changes with block demand under specified rules.
LET’S PICTURE IT
A published base rate can vary between service periods according to a rule, rather than being chosen separately by every customer.

This example supplies twenty-one thousand gas used. It is a simple teaching input, not a live estimate of a contract call.
This example supplies twenty-one thousand gas used. It is a simple teaching input, not a live estimate of a contract call.With base ten Gwei, priority cap two and total cap twenty, the effective rate is twelve Gwei per gas.Twenty-one thousand times twelve Gwei gives two hundred fifty-two thousand Gwei, or 0.000252 ETH.The base-fee component is 0.00021 ETH and is burned. The priority component is 0.000042 ETH for the block fee recipient.

Each relevant block has a value
For standard EIP-1559 execution pricing, the block’s base fee applies to included transactions. A sender’s signed total cap must be sufficient for it.
The update follows resource usage
The adjustment formula responds to usage relative to a target. Above-target and below-target blocks push the subsequent base fee in different directions under the rules. A displayed estimate concerns a particular time and state.
The base component is burned
This part of the execution fee is removed by protocol accounting rather than paid to a spendable proposer account. It should be separated from the effective priority-fee component in a breakdown.
A cap can become insufficient
A transaction prepared for a lower base fee can wait if later conditions exceed its total cap. A calculator with manual input explains the relationship but cannot promise future inclusion.
