Binance Gas fees consist of "Base Fee + Priority Fee," with the formula: Gas Fee = Gas Used × (Base Fee + Priority Fee). Actual costs range from $0.15 on the BNB Chain to $30 on the Ethereum Mainnet due to differences in Gas prices and block production mechanisms. On the Binance Official Website or within the Binance Official APP, withdrawals and on-chain transfers follow different structures: centralized withdrawals have a fixed fee (collected by Binance to cover on-chain costs), while Web3 wallet on-chain transfers are dynamically calculated based on real-time Gas, with users able to choose from Slow/Standard/Fast tiers. By understanding the Gas mechanism and using tips like choosing low-fee chains, operating during specific time windows, and batch execution, you can save an average of 40-70% on fees. iPhone users can refer to the iOS Installation Tutorial to complete the APP installation and experience the intelligent Gas suggestion feature in the built-in Web3 wallet.
Detailed Gas Fee Calculation Formula
Calculation After Ethereum EIP-1559
Gas Fee = Gas Used × (Base Fee + Priority Fee)
- Gas Used: Computational resources consumed by the transaction (Simple transfer: 21,000; Swap: approx. 150,000; NFT Mint: approx. 80,000).
- Base Fee: Automatically adjusted by the network, changing by 12.5% per block, rising during congestion.
- Priority Fee (Tip): Acceleration fee paid by users to miners/validators, typically in the 0.1-5 gwei range.
Example: Transferring USDT on Ethereum Mainnet, Gas Used = 65,000, Base Fee = 25 gwei, Priority = 1 gwei. Fee = 65,000 × 26 × 10⁻⁹ ETH = 0.00169 ETH ≈ $5.4
BNB Chain and Solana Calculation
BNB Chain uses a fixed Gas Price of 5 gwei. Transfer: 21,000 × 5 × 10⁻⁹ = 0.000105 BNB ≈ $0.065. Solana uses "5,000 lamports per signature + Priority Fee," with a single transaction generally costing < $0.002.

| BNB Chain | $0.05 | $0.08 | $0.5 | $0.8 |
| Arbitrum | $0.04 | $0.06 | $0.2 | $0.5 |
| Base | $0.02 | $0.03 | $0.1 | $0.2 |
| Optimism | $0.05 | $0.07 | $0.15 | $0.3 |
| Polygon | $0.005 | $0.008 | $0.02 | $0.05 |
| opBNB | $0.0003 | $0.0005 | $0.002 | $0.005 |
| Solana | $0.0005 | $0.0008 | $0.002 | $0.01 |
Binance Exchange Withdrawal Rates
Withdrawal fees include on-chain Gas plus Binance service fees. Common currencies (data as of April 2026):
| Currency | Network | Withdrawal Fee | Min Withdrawal |
|---|---|---|---|
| USDT | TRC-20 | 1 USDT | 10 |
| USDT | BEP-20 | 0.29 USDT | 10 |
| USDT | ERC-20 | 4.5 USDT | 20 |
| USDT | Solana | 1 USDT | 10 |
| BTC | BTC Mainnet | 0.0002 BTC | 0.001 |
| BTC | Lightning | 0 | 0.00001 |
| ETH | ERC-20 | 0.0012 ETH | 0.005 |
| ETH | Arbitrum | 0.00008 ETH | 0.001 |
| BNB | BEP-20 | 0.0001 BNB | 0.01 |
Conclusion: For USDT, prioritize TRC-20 or BEP-20; for ETH, prioritize Arbitrum/Base; for high-frequency small BTC amounts, use Lightning.
Eight Tips to Save on Gas
1. Choose Low-Fee Chains
For daily transfers, prioritize BNB Chain, Polygon, or Solana. For large amounts of stablecoins, choose TRC-20 (withdrawal fee is only 1 USDT).
2. Avoid Congested Periods
Highest Gas periods for Ethereum:
- 09:00-12:00 EST (Opening of weekday trading)
- During popular project Mint windows (Gas can surge to 200+ gwei)
Lowest Gas periods:
- Saturday 3-6 AM (UTC) is typically only 10-15 gwei.
- Use etherscan.io/gastracker to check real-time prices.
3. Use L2 and Aggregation Bridges
Bridging ERC-20 tokens from the mainnet to Arbitrum/Base before operating can drop a single Swap cost from $30 to $0.2, a 99% saving.
4. Batch Transactions
Doing a single Approval + multiple Swaps saves 30% compared to re-Approving every time. Safe (formerly Gnosis Safe) multisig wallets support batching, combining 10 transactions into 1.
5. 25% Discount with BNB
Hold BNB and enable "BNB Deduction" in account settings to reduce spot trading fees from 0.1% to 0.075%.
6. Choose Low Gas Consumption Contracts
- Uniswap V3 uses 20% less Gas than V2.
- 1inch aggregation routing is occasionally cheaper than going directly through a DEX.
- Curve is specifically optimized for stablecoin swaps.
7. Set Reasonable Priority Fees
For non-urgent transactions, set a 0.1-0.5 gwei Priority fee (on Ethereum). In MetaMask, for example, choosing the "Low" tier will increase confirmation time by about 30 seconds but save 40% on tips.
8. Use Gas Refund / Rebate Programs
Events like Binance Megadrop or HODLer Airdrop often refund Gas. Some L2s (like zkSync Era) have Paymaster contracts that pay Gas on your behalf.

Handling Emergencies
Stuck Transactions (Pending for over 30 minutes)
Option A: Speed Up Find the pending transaction in your wallet, click "Speed Up," and re-broadcast with a 10% higher Gas Price.
Option B: Cancel/Replace Send a transaction with the same nonce and 0 ETH to your own address, with a Gas Price at least 10% higher than the original.
Failed Due to Insufficient Gas
Failed transactions still deduct Gas Used × Gas Price (approx. 50% of estimate). To avoid this:
- Keep enough native tokens (at least $5 equivalent)
- Choose "Estimated + 20%" buffer when estimating.
Frequently Asked Questions
Why is my Gas higher than others? Possible reasons: high contract complexity, first-time Approval requiring more Gas, or MEV protection being enabled.
Are Gas fees refundable? Gas for failed transactions is not refunded, but the unused portion (Gas Limit - Gas Used) is returned to the wallet.
Is Layer 2 Gas really that low? Yes, Arbitrum/Base compress data and bundle it back to the mainnet, spreading the cost so it's only a few cents per transaction.
Why is Solana almost free? Block time is 400ms, each block has large capacity, and single computational resource costs are extremely low. Parallel execution also increases throughput.
Understanding the Gas mechanism and mastering these tips can save active on-chain users hundreds to thousands of dollars in fees annually. The core principle: use L2 over mainnet, use BNB Chain/Solana over Ethereum, use TRC-20 for large amounts, and use Lightning for high-frequency trades.
