Using BNB to pay for trading fees is one of the simplest and most effective ways to save money on Binance. Almost every trader should have it turned on. So how much does it actually save? Let's do the math.
How Much Does BNB Fee Deduction Save
With BNB fee deduction enabled, you get a 25% discount on spot trading fees. That means the default rate of 0.1% drops to 0.075%.
Let's put some real numbers on it: say your total spot trading volume for the month is 100,000 USDT. At the default 0.1% rate, you'd pay 100 USDT in fees. With BNB fee deduction, that drops to 75 USDT — saving you 25 USDT outright. The more you trade, the more you save.
How to Enable BNB Fee Deduction
It's very straightforward:
- Log into the Binance App or website
- Go to your "Account" or "Dashboard" page
- Find the "Use BNB to Pay for Fees" option
- Toggle it on
Once enabled, the system will automatically deduct the equivalent amount of BNB from your spot account to cover trading fees, instead of deducting from the traded asset. The prerequisite is that you have enough BNB in your account.
Auto-Buy BNB Feature
A lot of people enable BNB fee deduction but forget to buy BNB, so when the balance runs out, the discount stops working. Binance offers an "Auto-Convert Small Balances to BNB" feature that periodically converts your small leftover balances (dust) into BNB, keeping your BNB balance topped up.
Path: App → "Wallet" → "Spot" → "Convert Small Balances to BNB."
Alternatively, you can manually buy a small amount of BNB in advance — around 50–100 USDT worth will last you quite a while.
Can It Stack with Other Discounts
Yes. The BNB fee deduction and referral code fee rebates are calculated independently. If you haven't signed up yet, registering through a referral link lets you stack an additional fee discount on top of the BNB discount, bringing your effective rate below 0.075%.
Things to Keep in Mind
The BNB fee deduction provides the clearest discount on spot trading (25%). For futures trading, the BNB deduction rules are different — check Binance's official fee page for the latest details. Also, BNB's price fluctuates, so holding BNB does come with some price risk. However, since you only need a small amount for fee purposes, the exposure is minimal.
