Why Binance Withdrawal Fees and On-Chain Gas Fees Are Different
The withdrawal fee shown on Binance is the service fee you pay to Binance; the on-chain gas fee is the transaction fee you pay to the blockchain network. These two fees go to different recipients. Binance bundles them into one fixed amount, which is why it appears as one sum but actually comprises two different things.

First, the conclusion: Binance withdrawal fee ≠ on-chain gas fee
The withdrawal fee you see is actually a fixed amount that bundles "Binance's platform service fee + the gas fee it pays to the blockchain network on your behalf".
On-chain gas fee: Paid to miners/validators to package your transaction into a block. This fee goes to the blockchain network, not Binance, and fluctuates with network congestion in real time.
Binance withdrawal service fee: The operational cost Binance charges for processing your withdrawal request. This goes to Binance itself.
The fixed amount you see on the withdrawal confirmation page is the "all-inclusive price" Binance calculates by adding those two together.
Why the gas fee you see appears lower than expected
Many people assume "Binance withdrawal fee = on-chain gas fee", but in reality, Binance's withdrawal fee is usually higher than the real-time on-chain gas fee — because it already includes a portion of the platform service fee. Conversely, if the on-chain gas fee suddenly spikes, Binance may temporarily raise the withdrawal fee to cover its costs.
How to tell in practice
The fee displayed on the withdrawal page is what you will ultimately pay; you don't need to worry about "how much of that is gas." However, choosing a different network can lead to vastly different final costs.
Taking USDT as an example:
TRC-20 (TRON network): Fees are usually under $1, with fast arrival.
ERC-20 (Ethereum network): Can exceed $20 when the network is congested.
So when you see different fees shown for different networks on the withdrawal page, the underlying reason is the variance in on-chain gas fees themselves, on top of which Binance adds a service fee.

How to confirm you've understood correctly
Next time you withdraw, look at the "Fee" column on the withdrawal page — it will show a fixed number. Don't bother checking the real-time on-chain gas fee; that number is the total you'll pay. When choosing a network, compare a few options and pick the one with the lowest fee, provided your receiving address supports that network.
