How to Estimate Gas Fees

01Select your chainChoose the network you are transacting on — Ethereum, Polygon, or BSC. Each chain has its own gas dynamics: Ethereum uses ETH-denominated gas measured in gwei (1 gwei = 10⁻⁹ ETH), Polygon uses MATIC, and BSC uses BNB. Selecting the correct chain ensures accurate fee estimates for your target network.

02Fetch current tiersClick the fetch button to load the latest slow, standard, and fast gas tiers from our server-side cache. Gas prices fluctuate in real-time based on network demand — when more users compete for block space, validators/miners prioritize transactions paying higher gas prices. Our endpoint polls public RPC nodes and returns the current recommended gas price for each confirmation speed tier.

03Estimate your costEach tier shows the gas price in gwei and an approximate USD cost for a simple 21,000-gas transfer (the base cost for an ETH/native token send). The actual cost of your transaction depends on its gas limit — token swaps typically use 100,000-200,000 gas, while complex contract interactions can exceed 500,000 gas. Multiply the gwei price by your gas limit, then convert to ETH/BNB/MATIC to get the native cost.

No wallet connection is required. This tool only fetches public network fee data — no personal information is collected. Gas prices are public on-chain data.

About Gas Fee Estimator

Gas is the computational unit on EVM-compatible chains — every operation (sending tokens, swapping on a DEX, minting an NFT) consumes a specific amount of gas. The gas price (in gwei) is what you pay per unit of gas. Total fee = gas_used × gas_price. Gas fees serve two purposes: they compensate validators for securing the network, and they prevent spam by making computation economically costly. During periods of high demand (NFT mints, market volatility), gas prices can spike from 10 gwei to 200+ gwei on Ethereum. Polygon and BSC typically maintain sub-cent fees due to higher throughput and lower validator costs. The tool returns three tiers: Slow (cheapest, 5+ minutes), Standard (balanced), Fast (premium, 15 seconds).

When to use it

Use this before sending a transfer, swapping tokens, deploying a contract, or troubleshooting a stuck transaction. Comparing tiers helps you balance cost against confirmation speed — a 'slow' transaction at 20 gwei might take 5+ minutes but cost half as much as a 'fast' 60 gwei transaction that confirms in 15 seconds.

Tips & Tricks

•Gas fees can spike during high network activity (NFT drops, market crashes) — always refresh the data shortly before submitting.
•A standard ETH transfer uses 21,000 gas, but token swaps use 100,000-200,000 gas, and complex DeFi interactions can exceed 500,000 gas.
•Polygon and BSC typically have fees under $0.01, while Ethereum mainnet fees vary widely — a simple transfer can range from $0.50 to $50+.
•If your transaction is stuck, speed it up by resubmitting with a higher gas price (replace-by-fee) or cancel it with a 0-value tx to yourself.
