Margin interest keeps piling up usually because you haven't understood the "starting point" of interest calculation and where to check it. Starting April 30, 2026, the first interest charge on Binance margin loans is calculated based on the actual seconds you hold the loan. This means even if you repay a few minutes after borrowing, interest for those minutes will be charged and once charged, it is non-refundable.

To clear your liability details, you only need two steps: first, understand how interest is calculated; second, find where all your liability and interest records are shown.
Step 1: Understand the New Interest Rules to Avoid Unfair Charges
Before the end of April 2026, the rule was "interest charged for a full hour once you borrow." Now it is per-second interest, but the core logic remains: interest is settled every hour, and it will keep adding up if you hold past each full hour.
How Interest Is Calculated:
First interest charge: From the moment you borrow until the next full hour (e.g., 13:00, 14:00), interest is based on the actual seconds. Formula:
Borrowed amount × hourly interest rate × (actual seconds / 3,600).Example: You borrow 10,000 USDT at 05:30:49, hourly rate 0.0004%. Interest until 06:00:00 is only 0.0194 USDT, not a full hour's interest.
Subsequent interest: If the loan is not repaid after the full hour, the system charges interest for each complete hour until you repay.
Completion standard: You can use the formula above to calculate exactly how much interest has accrued on a specific loan at a given moment.
Risk warning: Although per-second interest looks fairer, interest is settled every hour and added to your total liabilities at settlement. If you borrow and hold for 1 hour and 1 minute, you will pay for 2 hours of interest. So, if you have enough funds, try to repay before the next full hour to save one hour's interest.
Step 2: Find the Liability Details Page and Clear Them One by One
Binance puts all liability and interest records in one place. Your job is to find it and then repay in order.
Where to Look:
Log in to Binance, click the [Wallet] icon, and go to [Margin Account].
Click [Orders] – [Margin Orders]. Here you will see 7 tabs.
Find and click the [Fund Flow] tab: This lets you track every fund movement in your Margin Account, including borrowing, repayment, trading, and liquidation. You can see the principal records of each loan here.
Find and click the [Interest History] tab: This records the borrowed coin, hourly interest details, and total interest.
What to Do:
In [Interest History], check the total interest already incurred and which coin's interest is accumulating.
Prepare enough funds in that coin (or swap to get it).
Manual repayment: On the Margin Account page, find the liability coin, click "Repay" or "Repay Liability", enter the amount, and prioritize repaying interest first, then principal.
Auto-repayment: Select "Auto-Repay" mode when placing an order. After the order is fully executed, the system will first use the obtained funds to repay interest, then principal. Note: Auto-repay only executes after the order is completely filled.
Completion standard: Go to the [Margin Account] page and confirm that the "Liability" and "Interest" fields both show zero, or values have dropped to an acceptable level.

Verification After Clearing
After clearing your liabilities, do a final check:
Go back to the [Interest History] tab and confirm that interest records for the current period have stopped generating or have been settled.
Exit the Margin Account page and refresh it to make sure the displayed liability and interest balances have updated. If the balance is not zero, it means there are still unsettled interest or principal. Repeat Step 2 to continue clearing.
Next Step: To prevent interest from piling up again, set a phone alarm after borrowing to remind yourself to check if you have repaid before the next full hour (e.g., 13:50). If you don't plan to repay immediately, record this liability in your ledger and check [Interest History] regularly to avoid compound interest.
