Calculate Layer 2 gas savings
Ethereum Layer 2 networks, such as Arbitrum, Optimism and Base, process transactions much more cheaply than Ethereum mainnet, or Layer 1, while inheriting its security. This calculator shows how much you save per transaction by using a Layer 2, how many times cheaper it is, and your total savings per month and year based on your transaction volume. A twelve-dollar mainnet fee versus a fifteen-cent Layer 2 fee saves 11.85 dollars per transaction, about 80 times cheaper.
Over many transactions, these savings add up dramatically.
Why use a Layer 2
Layer 2 networks bundle many transactions together and settle them on Ethereum, spreading the mainnet cost across all of them, which slashes per-transaction fees. For active users, traders and dapp interactions, moving activity to a Layer 2 can reduce fee spending enormously while keeping funds within the Ethereum ecosystem. The main trade-offs are bridging time and the specifics of each Layer 2 security model.
Fees on both layers vary with network demand, so use representative figures for your transactions. All calculation happens locally in your browser.
Notes on these estimates
Because the l2 gas savings calculator runs entirely in your browser, you can adjust every input and see the results update instantly, with nothing uploaded and no wallet connection required. The figures are estimates based on the values you enter, so use current, accurate numbers for the most useful output, and treat the results as a planning guide rather than financial advice.

Frequently Asked Questions
What is a Layer 2?
It is a network built on top of Ethereum that processes transactions cheaply off-chain and settles them on mainnet, inheriting its security.
Why are Layer 2 fees so much lower?
Layer 2s batch many transactions and settle them together on Ethereum, spreading the mainnet cost across all of them.
Are there trade-offs to using a Layer 2?
Yes. Bridging assets takes time, and each Layer 2 has its own security and decentralisation characteristics to consider.
Do fees change over time?
Yes. Fees on both Layer 1 and Layer 2 vary with network demand, so use representative figures for an accurate savings estimate.
