This example supplies twenty-one thousand gas used. It is a simple teaching input, not a live estimate of a contract call.

Animated local teaching model. No wallet, RPC or live blockchain data. Some labels and hashes are abbreviated for readability.

How to use this gas calculator

Calculate an EIP-1559 execution fee from gas used, base fee, priority fee cap and maximum fee cap. Uses manual inputs only; this is not a live gas estimator. Start with the prefilled example, change an input, and run the calculation. Invalid values produce an explanation rather than a misleading result.

What the result means

These results describe your supplied inputs. They do not query a blockchain, check balances, estimate current network conditions, or submit transactions. Read gas without the guesswork for the meaning and limits of the calculation.
