Binance margin fees: 0.1% trading fee plus hourly interest on what you borrow

A margin trade on Binance has two costs. The order is charged at the spot rate, 0.100% maker and taker for a regular user, and the amount you borrow accrues interest every hour until it is repaid. On 13 October 2026, Binance's public fee page listed USDT at 0.00053771% per hour, shown as 4.71% a year, for regular users. The figures in this article were read from Binance's pages on that date without logging in, and they cover binance.com.

The trading fee is the spot fee, charged on the whole order

The Trading tab of the fee page puts both products under one heading, "Spot & Margin", with one table. A regular user pays 0.100% as maker or taker, or 0.075% when the fee is paid in BNB.

The percentage applies to the executed order value, which includes the borrowed part. With 1,000 USDT of your own and 1,000 USDT borrowed, a 2,000 USDT buy carries a fee of 2 USDT at the standard rate. Closing the position is a second order with its own fee. How the 0.1% spot fee is calculated explains why the fee can be deducted in the coin you receive, and the spot fee calculator does the arithmetic for other order sizes.

Interest depends on the coin you borrow and changes every hour

The rate belongs to the borrowed coin. Buying BTC with borrowed USDT pays the USDT rate. Selling borrowed BTC to open a short pays the BTC rate.

These are regular-user rates from 13 October 2026. The first twenty coins on the page ranged from 0.43% a year for BTC to 59.49% for DUSK, and five of the twenty were above 45%, so search for the coin before borrowing it.

Binance's interest FAQ says margin rates "change every hour based on current market conditions". The yearly figure is the hourly rate multiplied by 24 and by 365. It describes the rate at that moment and is not a price fixed for a year. The Interest History page under Margin Data keeps up to 30 days of past rates.

Futures positions do not borrow coins and pay funding instead of loan interest. How Binance futures fees and funding are calculated covers that product.

How the first hour and later hours are charged

The same FAQ sets out the rule that has applied since 30 April 2026, 08:00 UTC:

• The first charge is prorated by the second, from the moment you borrow to the next full hour.
• At the start of each hour after that (13:00, 14:00 and so on), one full hour is charged at the rate in force at that time.
• Interest is simple interest and is added to the debt each time it accrues.
• Repaying partway through an hour stops later charges. The hour already entered is still charged in full.
• Each charge is rounded up to 8 decimal places.

Take 1,000 USDT borrowed at 10:20:00 and repaid at 13:10:00, with the rate staying at 0.00053771%:

• First charge, 10:20 to 11:00: 1,000 × 0.00053771% × (2,400 ÷ 3,600) = 0.00358474 USDT
• Charges at 11:00, 12:00 and 13:00: 1,000 × 0.00053771% = 0.0053771 USDT each
• Total: 0.01971604 USDT

The loan was open for 2 hours 50 minutes and was charged for 3 hours 40 minutes, because the hour starting at 13:00 had already been entered.

When interest overtakes the trading fee

At the USDT rate above, 1,000 USDT borrowed costs about 0.129 USDT per 24 hours, or about 3.87 USDT over 30 days if the rate did not move. Opening and closing a 2,000 USDT position costs about 4 USDT in trading fees at 0.100%. On those numbers the trading fee is the larger cost for roughly the first month.

A coin with a high rate reverses that quickly. STX was listed at 0.00588013% per hour that day, 51.51% a year. A loan worth 1,000 USDT at that rate costs the equivalent of about 1.41 USDT a day and passes 4 USDT in under three days.

Interest is added to what you owe, so a position that is left alone still drifts toward a lower margin level. Binance's FAQ recommends watching both the rate and the margin level "to avoid potential liquidation" from rate changes and accumulated interest. A margin position can be liquidated at a loss.

Paying fees and interest with BNB

Binance's help article on BNB in margin accounts describes two separate switches, [Use BNB to pay fees] and [Use BNB to pay Margin interests]. On the website they are under Profile, Settings, Trade, Manage, Fee Deduction.

Trading fees. Paying in BNB gives 25% off on both Cross and Isolated Margin trades. For Cross Margin the BNB has to be in the Cross Margin account. For Isolated Margin the standard fee is charged first in the isolated account; the discounted fee is then taken from BNB in the Spot account, and the first fee is refunded within 48 hours.

Interest. The BNB option applies to Cross Margin only. The fee page labels it "BNB 5% off", and the Margin Data page showed USDT at 4.47% a year with the discount against 4.71% without. Once the switch is on, interest on every coin you have borrowed is calculated and accrued in BNB, whatever your BNB balance is. Interest that accrued before you turned it on is not converted.

Where to check what you were charged

On the website, click the wallet icon and go to Margin, Orders, Margin Order. Three tabs hold the costs:

1. Trade History: expand a record to see the trading fee for that fill.
2. Debt History: the Interest tab lists the loan coin and the hourly interest records.
3. Liquidation: if a position was liquidated, the record shows the time, the margin level and the liquidation fee charged.

The pages read for this article do not state the liquidation fee rate, so no figure is given here. Interest rates move hourly; read the table again on the day you borrow.
