The BNB fee discount toggle is in your account settings. You can turn it on before your first trade. The basic path is: App bottom right Account → top right Settings → find BNB Discount → turn on Use BNB to pay fees. After you turn it on, the system will automatically use BNB to pay trading fees when you trade, as long as your spot account has enough available BNB.
Step 1: Go to Account Settings and Find the Toggle
To find the BNB discount toggle: open the Binance App, tap Account in the bottom right, then tap the gear icon in the top right to enter Settings. Scroll down and tap BNB Discount. You will see the Use BNB to Pay Fees toggle.
Step 2: Make Sure Your Account Has Available BNB
Check that your spot account has enough BNB balance. Go back to the Assets page and check the available BNB balance in your spot account. Note: BNB in staking or locked Earn products cannot be used. It must be available in your spot account. Keep at least 0.001 BNB in your spot account.
Step 3: Turn On the Toggle and Verify
Turn on the toggle, then use a small trade to confirm it works. Go back to the BNB Discount page and switch the toggle to the on position (green or to the right). Then place a small spot order. After it fills, go to the order details page and look at the fee section. If the order details show that the fee was paid in BNB and there is a discounted mark, the setting is working.
Risk Reminder
If there is not enough BNB in your spot account, the system will not warn you about a low balance. It will charge the fee in another coin at the original 0.1% rate and will not automatically use more BNB. Check your BNB balance before placing an order.
Common Reasons for Failure
- You bought BNB but placed an order before the BNB arrived, so the balance was 0 and the discount did not work.
- You put BNB into Earn or staking products, so the discount cannot use that BNB.
- You only turned on the toggle but did not have enough BNB in the account, so fees were still charged at the original rate.
How to Verify After Setting It Up
After turning on the toggle, you can make a small spot trade to test it. After the trade fills, open the order details in History and check if the fee section shows BNB discount and how much BNB was deducted. If you see that, the setting is working.
