BNB Chain gas estimator
Withdrawing bStocks to the Binance Web3 Wallet, or transferring, providing liquidity or lending on-chain, all cost a little gas. The math is simple: gas price (gwei) × gas limit = BNB consumed, then multiply by the BNB price for the dollar cost. Fill in the three fields below for a live result. Everything runs in your browser.

How gas works on BNB Chain
Every on-chain action has to be packaged by miners/validators, and the cost is gas. The formula is fixed: BNB consumed = gas price × gas limit ÷ 10⁹. Gas price is quoted in gwei (1 gwei = 0.000000001 BNB), and gas limit is how much compute the action is estimated to burn.
Gas price on BNB Chain is usually very low, often hovering around 1 gwei and rising when the network is busy. So a plain transfer often costs only a few cents. What really drives the cost is not the unit price but the complexity of the action: a simple transfer is about 21000, a token transfer is higher, and swaps, LP and lending contract interactions can reach hundreds of thousands of gas limit.
- Withdrawing bStocks to a wallet: a token transfer, so the gas limit is a bit higher than a plain transfer, but on BNB Chain it is still cents-level overall.
- Operating in DeFi: the first approve, plus swaps and LP, cost a little more because the contract logic is heavier.
When the wallet sends a transaction it gives you an estimated gas; the figure shown in the wallet at the time is what applies. The tiers on this page are common orders of magnitude, so you have a rough sense of the scale. You can check the live gas price at BNB Chain official or in an explorer.
Keep a little BNB in the wallet for gas, otherwise you cannot send a transaction even if you hold bStocks. Confirm you have a small amount of BNB before withdrawing. The trading fee (charged when you buy or sell on Binance) and on-chain gas are two different things; work out the former with the fee calculator.
How to spend less gas
Avoid network peaks for non-urgent actions; combine what you can (for example, withdraw once in a larger amount instead of many small ones); approve only the amount you need in DeFi.
