ETH price $2,039.13 from CoinGecko. Gas used for sending ETH is fixed at 21,000; other actions depend on the contract and are typical values. On Arbitrum One, an L1 data fee is added on top of these costs. Calculate a custom amount →

How fees work on Arbitrum One
Fees on Arbitrum One are paid in ETH and quoted in gwei. Each transaction pays for two things: the gas it uses to execute on Arbitrum, and a share of the cost of posting transaction data to Ethereum. Arbitrum folds both into a single gas figure. The L1 cost is converted into extra L2 gas units, so the gas used shown for an Arbitrum transaction already includes the data posting cost.
The L2 gas price has a set floor that anyone can read from the ArbGasInfo precompile with the getMinimumGasPrice method. Above that floor, Arbitrum tracks a gas backlog against a target rate. When usage stays above the target, the base fee rises exponentially, and the docs give the example that exceeding the target by 1% raises the fee by 10%. When the backlog shrinks, the base fee falls again.
Arbitrum One has tip collection enabled and runs Priority Gas Auction ordering. A priority fee sets your position in the sequencer's queue, and the chain collects it, with the docs listing a split of 97% to the DAO treasury and 3% to the Developer Guild. A tip does not reduce the base fee you owe. On Arbitrum chains without these settings, tips are ignored.
For the L1 part, Arbitrum compresses each transaction on its own with Brotli at the lowest compression level and multiplies the result by 16 to estimate its footprint in data units. That size is multiplied by a price per data unit. An adaptive algorithm adjusts this price after each batch report, raising it when fees collected fall short of the real cost of posting batches to Ethereum and lowering it when there is a surplus.
Fees rise when Arbitrum demand pushes the backlog over target, or when Ethereum posting costs go up and the per-unit L1 price follows. Because the L1 part depends on compressed size, transactions with large or random-looking calldata cost more than simple transfers. A practical tip is to let your wallet estimate gas, since the L1 portion changes the gas limit, and to add a tip only when order in the queue matters.

How we measure Arbitrum One gas
Every 5 minutes our server calls eth_feeHistory for the last 20 blocks on a live public Arbitrum One RPC endpoint (last: arbitrum.gateway.tenderly.co). Slow, standard and fast are the next block’s base fee plus the 25th, 50th and 75th percentile of priority tips paid in those blocks. Block use: 31% of the gas target on average.

Arbitrum One gas FAQ
What is the current Arbitrum One gas price?
At the last check the standard gas price on Arbitrum One was 0.020 gwei (base fee 0.020 gwei plus a priority tip). It updates every 5 minutes.
What is gwei?
Gwei is a billionth of one ETH. Gas prices are quoted in gwei; your fee is gas used × gas price.
Why do gas prices change?
On EIP-1559 networks the base fee rises when blocks are fuller than the target and falls when they are emptier, so busy periods cost more.
Is the gas price the full fee on Arbitrum One?
No. Arbitrum One is an L2: besides the L2 execution gas shown here, each transaction pays an L1 data fee for posting its data to Ethereum. Your wallet shows the total before you sign.
How do you get these numbers?
Every 5 minutes we call eth_feeHistory for the last 20 blocks on a live public RPC endpoint. Slow, standard and fast are the next base fee plus the 25th, 50th and 75th percentile of priority tips paid in those blocks.
