When trading on Binance, using BNB to deduct trading fees is the simplest and most effective way to save money. Many people know about this feature but are unclear on exactly how much they can save. Today, let's calculate it clearly. First, check your current fee rates on the official Binance website, and then enable the BNB deduction feature on the official Binance App. Apple users should read the iOS installation guide to install the App first.
What is BNB Fee Deduction
BNB (Binance Coin) is the native platform token issued by the Binance exchange. Binance offers a feature: if you hold BNB, you can choose to use BNB to pay for your trading fees and enjoy a certain discount.
Current Discount Rate
By using BNB to deduct spot trading fees, you can enjoy a 25% discount. That is to say:
- Without BNB deduction: Fee rate is 0.1%
- With BNB deduction: Fee rate is 0.075% (0.1% × 75% = 0.075%)
Do not underestimate this 0.025% difference; the accumulated amount can be very substantial.
How Much Can You Actually Save
Let's calculate using different trading volumes:
Small Volume Traders
Monthly Trading Volume: 10,000 USDT (about 5 round-trip trades of 1,000 USDT each)
- Without BNB deduction: 10 times × 1,000 × 0.1% = 10 USDT/month
- With BNB deduction: 10 times × 1,000 × 0.075% = 7.5 USDT/month
- Save 2.5 USDT per month, 30 USDT per year
Medium Volume Traders
Monthly Trading Volume: 100,000 USDT
- Without BNB deduction: 100,000 × 0.1% = 100 USDT/month
- With BNB deduction: 100,000 × 0.075% = 75 USDT/month
- Save 25 USDT per month, 300 USDT per year
Active Traders
Monthly Trading Volume: 1,000,000 USDT (about 1 million)
- Without BNB deduction: 1,000,000 × 0.1% = 1,000 USDT/month
- With BNB deduction: 1,000,000 × 0.075% = 750 USDT/month
- Save 250 USDT per month, 3,000 USDT per year
The larger your trading volume, the more money you save with BNB deduction. For professional traders, these savings are highly significant.
How to Enable BNB Fee Deduction
Step 1: Buy BNB
You first need to buy some BNB on Binance. Exactly how much you buy depends on your trading frequency:
- Occasional trading: Buying $10-$20 equivalent of BNB is enough for several months
- Regular trading: Buying around $50-$100 of BNB
- Frequent trading: Buying $200 or more of BNB
How to buy BNB: Find the BNB/USDT trading pair in the spot market and buy it using USDT.
Step 2: Enable BNB Deduction Settings
- Open the Binance App
- Click on the avatar in the top left corner to enter the user center
- Find the "Fee Rates" or "Fee Discount" option
- Turn on the "Use BNB to pay for fees" switch
- Confirm the completion
Once enabled, every time you make a spot trade, the fee will be automatically deducted from your BNB balance, and you will enjoy the discount.
Step 3: Keep Sufficient BNB Balance
After enabling BNB deduction, the fee for each trade will consume your BNB. You need to periodically check your BNB balance and replenish it in time when it runs low.
If your BNB balance drops to zero, the system will automatically revert to deducting fees using the traded cryptocurrency, at which point you will no longer enjoy the discount.
How BNB Deduction Works
Fee Calculation Process
Taking an actual trade as an example:
You buy BTC with 10,000 USDT and have enabled BNB deduction.
- Calculate the base fee: 10,000 × 0.1% = 10 USDT
- Apply the BNB discount: 10 × 75% = 7.5 USDT
- Convert 7.5 USDT into equivalent BNB: Assuming the BNB price is 600 USDT, then deduct 7.5 / 600 = 0.0125 BNB
Your spot account receives the full amount of BTC (no fee deducted from it), and the fee is deducted from your BNB balance.
Handling Insufficient BNB Balance
Suppose you only have 0.005 BNB left (worth 3 USDT), but the fee requires 0.0125 BNB (worth 7.5 USDT).
- 0.005 BNB is used to deduct part of the fee (enjoying the discount)
- The remaining part is deducted from the cryptocurrency obtained from the trade (not enjoying the discount)
Therefore, keeping an adequate BNB balance is very important.
What Else is BNB Used For Besides Fee Deduction
Participate in Launchpad
Binance periodically launches Launchpad (new token issuance) events, and users holding BNB can participate in subscribing to newly listed tokens. Some Launchpad projects offer substantial returns.
Participate in Launchpool
Similar to Launchpad, but Launchpool allows you to earn new tokens for free by staking BNB. You don't need to spend money to buy them; you just need to "lock" your BNB for a certain period.
VIP Level Boost
Holding BNB is one of the criteria for assessing Binance VIP levels. The more BNB you hold, the easier it is to reach a higher VIP level, thereby enjoying lower base fee rates.
BNB's Own Investment Value
As the platform token of the world's largest exchange, BNB has certain investment value. However, all cryptocurrencies carry volatility risks, so the amount of BNB purchased for fee deduction should not be excessively large.
Common Questions About BNB Deduction
Can BNB Deduction be Used for Futures Trading?
Yes. Futures trading also supports BNB fee deduction, with a discount rate similar to spot trading. If you trade futures, enabling BNB deduction can also save you a lot.
Does BNB Price Fluctuation Affect Fees?
No. The BNB deduction discount is based on a percentage of the fee amount, not the price of BNB. Regardless of whether BNB rises or falls, the discount percentage you enjoy remains the same.
However, a drop in the BNB price means the BNB you previously bought has depreciated; this loss needs to be compared against the saved fees. But since the amount of BNB used for fee deduction is usually very small, this impact is minimal.
How Much BNB Should I Buy?
Estimate based on your trading frequency. Simple formula:
Monthly required BNB amount = Monthly trading volume × 0.075% ÷ Current BNB price
Example: Monthly trading volume is 50,000 USDT, and the BNB price is 600 USDT. Monthly required BNB = 50,000 × 0.075% ÷ 600 = 0.0625 BNB ≈ 37.5 USDT
Buying 40 USDT worth of BNB is enough for a month. In practice, it is recommended to buy a bit more to leave a margin.
Which is More Important: BNB Deduction or VIP Level?
The two are complementary:
- BNB Deduction: Available to everyone, takes effect immediately, saves 25%
- VIP Level: Requires a large trading volume to upgrade, lowers the base fee rate
For ordinary users, simply enabling BNB deduction is already very good. Upgrading the VIP level requires a monthly trading volume reaching the million USDT level, which is unrealistic for most people.
If you both have enabled BNB deduction and possess a VIP level, the discounts of the two can be stacked. For example, the Maker fee rate for VIP 1 is 0.09%; with a 25% discount from BNB deduction, the final fee rate is 0.09% × 75% = 0.0675%.
Summary of Practical Advice
- Enable BNB deduction right now: This is the simplest way to save money, with zero barriers to entry.
- Buy only a small amount of BNB: Tens to hundreds of dollars worth of BNB is enough for an ordinary user for a long time.
- Periodically check your balance: Replenish BNB when it runs out to ensure every trade enjoys the discount.
- Don't buy too much BNB just for fee deduction: BNB itself carries price volatility risks.
- Combine with limit orders: Limit orders enjoy Maker fee rates; when stacked with the BNB deduction discount, the effect is even better.
Frequently Asked Questions (FAQ)
Q1: Will the BNB fee deduction discount change?
Yes. Historically, Binance has adjusted the discount percentage for BNB deduction multiple times. The earliest was a 50% discount (half price), which was gradually reduced. The discount percentage may continue to be adjusted in the future, subject to official Binance announcements.
Q2: Will BNB be deducted when I am not trading?
No. BNB is only deducted as a fee when you actually execute a trade. If you don't trade, your BNB balance will not decrease (though the market price of BNB will fluctuate).
Q3: Will an insufficient BNB balance affect my trades?
It will not affect the trade itself. If your BNB balance is insufficient to cover the entire fee, the system will use BNB to pay the portion it can cover, and the remaining part will be deducted from the traded cryptocurrency. The trade will not fail because of insufficient BNB.
Q4: How much BNB is deducted for each trade after enabling BNB deduction?
It depends on the trading amount and the current BNB price. For instance, for a trading amount of 1,000 USDT, the 0.075% fee is 0.75 USDT; if the BNB price is 600 USDT, then 0.75 / 600 = 0.00125 BNB is deducted.
Q5: Are there other ways to further reduce fees after enabling BNB deduction?
You can combine the following methods: use limit orders (enjoy Maker fee rates instead of Taker fee rates), upgrade your VIP level (requires larger trading volume), and register using an invitation code with commission rebates. Stacking multiple methods can reduce your fees to a very low level.
