How to pay Binance fees with BNB — and how much BNB to keep
Binance will knock a quarter off your spot trading fee if you let it take the fee in BNB, its own coin. Most guides stop there: flip the switch, save 25%. Two things get left out. The switch works only while there is BNB in the right wallet, and when the BNB runs out the full fee comes back without any warning. And the BNB you hold for the discount is a coin that moves. On 7 October 2026 we read Binance’s fee schedule and its help article on the switch, then checked 365 thirty-day stretches of BNB’s price to see how often a fall in BNB wiped out a month of savings. This guide walks through the setting, then the arithmetic most people skip.
KEY TAKEAWAYS
- Regular-tier spot fee on Binance, read 7 Oct 2026: 0.100% maker and taker. With BNB deduction on: 0.075%. On a $10,000 buy-and-sell that is $15 instead of $20.
- The BNB has to sit in your Spot account. For USDⓈ-M futures there is a separate switch, and the BNB has to be moved into the futures account; the discount there is 10%, not 25%.
- If your BNB runs out, Binance charges the normal fee again. Nothing pops up to tell you.
- Keep about one month of fees in BNB. In the past year BNB fell far enough in a 30-day stretch to cancel that month’s saving in 7 of 365 stretches when you held one month of fees — and in 170 of 365 when you held a whole BNB for a $10,000-a-month habit.
What does paying fees in BNB actually change?
It changes two things: the rate, and the coin the fee is taken in. Without the setting, Binance takes its fee out of whatever you receive from the trade. With it on, it works out a smaller fee and takes that in BNB instead, leaving the coin you bought untouched.
Binance’s own example in its help article shows the mechanics. A regular user buys 10 ETH. The normal fee is 0.1% of what you receive, so 0.01 ETH. With the setting on, the fee is 0.075%, so 0.0075 ETH — but it is not taken in ETH. Binance converts it to BNB at the market rate and takes that from your BNB balance. You keep all 10 ETH.
The rates come from Binance’s fee schedule. For the Regular tier — anyone under $1,000,000 of spot volume in 30 days, which is almost every beginner — maker and taker are both 0.100%, and the “BNB 25% off” column reads 0.07500%. (Maker means your order waited in the order book; taker means it filled straight away. Our glossary page on maker and taker fees explains the difference.)
In dollars, for someone who buys $10,000 of a coin and later sells it (so $20,000 of trading volume in total):
| Regular tier, $10,000 in and out | Fee rate | Fee on $20,000 of volume |
|---|---|---|
| Spot, BNB deduction off | 0.100% | $20.00 |
| Spot, BNB deduction on | 0.075% | $15.00 |
| USDⓈ-M futures taker, off | 0.050% | $10.00 |
| USDⓈ-M futures taker, on (10% off) | 0.045% | $9.00 |
Rates read on Binance’s fee pages on 7 October 2026 (spot) and in its futures fee article updated 1 May 2026. Check the live schedule before you rely on them; Binance’s help article says the 25% discount is “valid until further notice”.
Where is the switch on the website and the app?
There are four places to flip it, and they all control the same setting. Binance calls it [Using BNB Deduction] on the website and [Use BNB to pay fees] in the app. You need to be logged in for all of them, so the steps below use Binance’s own wording and its own help-centre screenshots.
- Website, from the trading page: open any Spot trading page, click [Fee Level], and switch on [BNB/USDT].
- Website, from your account: open Fees & Transactions Overview and switch on the button under [BNB Discount].
- App, from settings: go to [Account Center], tap the [Settings] icon at the top right, tap [BNB Discount], and switch on [Use BNB to pay fees].
- App, from the trade screen: go to [Trade] → [Spot], tap [...], then [Fee].
Look closely at the second half of that screenshot. The “Using BNB” screen has three switches, not one: spot fees (25% off), margin interest (5% off) and USDⓈ-M futures fees (10% off). Turning on the first does nothing for the other two. That is the detail people miss when they say “I turned it on and my futures fees didn’t change”.
The setting only works if there is BNB in your Spot account. Binance’s wording is direct: you “must have BNB in your Spot Account”. BNB sitting in the Funding account — where coins often land after a P2P purchase — does not count. Move it to Spot with a free internal transfer.
Does it work on Binance Futures too?
Yes, but for less, and with two extra steps. On USDⓈ-M perpetual futures the discount is 10%, so the Regular-tier rates of 0.020% maker and 0.050% taker become 0.018% and 0.045%. On a $10,000 position opened and closed with market orders that is $9.00 in fees instead of $10.00 — a dollar.
The two extra steps: switch on the futures toggle (the third switch in the screenshot above), and transfer BNB into your USDⓈ-M Futures account. Binance’s futures fee article says that if the BNB in that account is not enough, it deducts USDT instead and you lose the discount. BNB in your Spot account is invisible to the futures side.
If you are new to futures, the dollar you save per $10,000 is the least important number on that screen. Our liquidation price guide covers the ones that matter more.
How much BNB should you keep?
About one month of fees. Work it out from how much you trade, not from how much BNB feels like “enough”. Count every buy and every sell as volume: buying $500 of a coin and selling it later is $1,000 of volume.
The table uses the Regular-tier spot rate and BNB at 768.59 USDT, Binance’s BNB/USDT price at 07:15 UTC on 7 October 2026.
| Your spot volume per month | Fees without BNB | Fees with BNB | Saved per month | BNB used per month |
|---|---|---|---|---|
| $2,000 | $2.00 | $1.50 | $0.50 | 0.0020 BNB |
| $10,000 | $10.00 | $7.50 | $2.50 | 0.0098 BNB |
| $50,000 | $50.00 | $37.50 | $12.50 | 0.0488 BNB |
| $250,000 | $250.00 | $187.50 | $62.50 | 0.2440 BNB |
Two practical limits shape the first purchase. Binance’s BNB/USDT market has a minimum order of 5 USDT (its own exchange rules, read 7 Oct 2026), so the smallest BNB buy is about 0.007 BNB, or $5.38 at that price. For someone trading $2,000 a month, that minimum already covers more than three months of fees. For someone trading $10,000 a month, one $7.50 top-up covers a month.
Notice what the table implies. A whole BNB — a number that sounds tidy — is 768 dollars of a single coin. At $10,000 of volume a month it would pay your fees for more than eight years. That is not a fee budget; it is an investment in BNB, and it should be judged as one.
Can holding BNB cost more than the discount saves?
Yes, and how likely it is depends almost entirely on how much BNB you hold. The discount saves 0.025% of your volume each month. The BNB you hold for it rises and falls with the market. If BNB drops far enough in a month, the fall in the value of your BNB is bigger than the fee you saved.
Here is the break-even. If you hold H months of fees in BNB, BNB has to fall by 1 ÷ (3 × H) in a month to cancel that month’s saving. Hold one month of fees and BNB has to drop a third. Hold a year’s worth and a 2.8% dip does it.
We checked that against BNB’s real history: every 30-day stretch ending between 8 October 2025 and 7 October 2026 (365 of them), using Binance’s daily BNB/USDT closing prices, then the same for the two years to 7 October 2026.
| BNB you hold | Monthly fall that cancels the month’s saving | 30-day stretches with a bigger fall, past year | Past two years |
|---|---|---|---|
| 1 month of fees | 33.3% | 7 of 365 (1.9%) | 1.0% |
| 3 months of fees | 11.1% | 74 of 365 (20.3%) | 11.8% |
| 12 months of fees | 2.8% | 148 of 365 (40.5%) | 32.2% |
| 1 whole BNB, at $10,000 volume a month (about 102 months of fees) | 0.33% | 170 of 365 (46.6%) | 39.7% |
The worst stretch in the year was not hypothetical. From the daily close of 13 January 2026 to the close of 12 February 2026, BNB fell from 943.73 to 614.29 USDT — −34.9% in 30 days. Someone holding exactly one month of fees lost slightly more on the BNB than the discount saved them that month. Someone holding a whole BNB for the discount lost about $329 on it, against $2.50 of fee savings.
Upside works the same way — in the best stretch of the year BNB rose 48.9% in 30 days (8 September to 8 October 2025). That is the point: once you hold more than a month or two of fees, the result is decided by BNB’s price, not by the 25% discount. If you want to own BNB, decide that on its own merits; our BNB coin page is a starting point. If you only want cheaper fees, keep the balance small and top it up.
This test has limits. It measures one year of one coin’s history; a calmer or wilder year would give different shares. It also ignores that you spend the BNB gradually through the month, which makes the real exposure a little smaller than the table assumes. The direction of the result does not change: the more BNB you park, the more the discount becomes a side issue.
How do you check the discount is really applied?
Look at the fee after the trade, not before it. The order form’s [Est. Fee] line keeps showing the fee in the coin you will receive, even with the setting on. Binance explains why in the same help article: it cannot know the exact filled amount when you place the order, so it shows an estimate in the receiving coin. Many people see that line, assume the switch failed, and turn it off and on again.
The check that works:
- Place a small trade after switching the setting on.
- Open Trade History for that order.
- The fee column should show an amount in BNB. If it shows the coin you received (or USDT on a sale), the discount did not apply — usually because the BNB is in the wrong account or has run out.
Then make it a habit: look at your BNB balance once a month, at the same time you would check anything else on the account. When BNB runs out, Binance simply goes back to the full fee. Its help article puts it plainly — with too little BNB, “you’ll be charged the original fee”.
When is the BNB discount not worth it?
When the dollars are too small to matter, or when holding BNB is something you would rather not do. The discount is a percentage of your volume. At $2,000 a month it is fifty cents. If buying BNB means one more purchase, one more balance to watch and one more coin moving in your account, skipping it is a reasonable choice — a forgotten 0.025% will not decide whether you make money.
It is also the wrong focus for most beginners. On Binance spot the maker and taker rates are the same for the Regular tier, so the order type does not change the fee, but a market order in a thin market can lose more to the spread than the whole BNB discount saves. Our Binance fees guide lists the costs that are bigger than the trading fee, including the liquidation clearance fee on futures.
And it does not carry over to other exchanges. OKX’s trading-fee FAQ (updated 3 September 2026) says OKB no longer reduces trading fees, and Bybit runs its own MNT programme with separate rules. If you split trading between exchanges, only the Binance part benefits.
Common mistakes
Leaving the BNB in the Funding account. The discount reads your Spot account only. A P2P purchase often lands in Funding; move it.
Assuming the spot switch covers futures. Futures has its own switch and needs BNB inside the USDⓈ-M Futures account. Spot BNB is not used there.
Buying a “round” amount of BNB. One whole BNB at $10,000 of monthly volume is about eight years of fees. Its price swings will dwarf the discount.
Reading [Est. Fee] as proof the setting failed. That line shows an estimate in the coin you receive. Check the fee column in Trade History instead.
Letting the balance run to zero. The full fee returns silently. A monthly look at the BNB balance is enough.
Selling your BNB to pay for a trade without noticing. If BNB is the coin you trade, the fee comes out of the same balance you are trading, so leave a margin above the amount you sell.
Frequently asked questions
How do I turn on BNB fee deduction on Binance?
On the website, open a Spot trading page, click [Fee Level] and switch on [BNB/USDT], or switch on the button under [BNB Discount] in Fees & Transactions Overview. In the app, go to Account Center, tap Settings, tap BNB Discount and switch on Use BNB to pay fees. Keep some BNB in your Spot account.
How much do you save by paying Binance fees with BNB?
For the Regular tier on 7 October 2026, spot fees fall from 0.100% to 0.075%, which is $5 saved on a $10,000 buy-and-sell. USDⓈ-M futures fees fall by 10%, from 0.050% to 0.045% for a market order, which is $1 saved on a $10,000 position opened and closed.
Why am I still paying the full fee after turning on BNB deduction?
Usually because there is no BNB, or not enough BNB, in the right account. Spot trades need BNB in the Spot account; USDⓈ-M futures need BNB in the futures account and their own switch. When the BNB is insufficient Binance charges the original fee. Confirm in Trade History that the fee shows in BNB.
How much BNB should I hold for trading fees?
About one month of fees: your monthly trading volume times 0.075%. At $10,000 of volume a month that is $7.50 of BNB. Holding much more turns the discount into a bet on BNB’s price, which fell by more than 10% in 23% of 30-day stretches in the year to 7 October 2026.
