Binance Margin to Update Interest Calculation Method for Loans

According to the announcement from Binance, the platform is set to revise its interest calculation method for Margin Loans, effective from 2026-04-30 08:00 (UTC). This change aims to enhance clarity and align interest charges more closely with the actual borrowing time. Users are advised to review the updated rules and plan their borrowing and trading activities accordingly. The key modification involves the first interest charge for a new Margin Loan, which will now be calculated on a prorated basis. This calculation will consider the actual time elapsed between the fund borrowing time and the next hourly settlement time. Specifically, interest will begin accruing immediately upon loan creation. For the initial interest period, the charge will be computed proportionally based on the exact number of seconds from the borrowing time to the subsequent hourly calculation time. The formula for this calculation is: First interest = Principal amount * Hourly interest rate * (Actual seconds / 3,600). Following the first interest period, interest will continue to accrue hourly on a standard schedule until the loan is fully repaid. For example, if a user borrows 10,000 USDT at 2026-04-30 05:30:49 (UTC) with an hourly interest rate of 0.0004%, the new rule calculates the interest as 0.01945556 USDT for the first period, compared to 0.04 USDT under the old rule. The next hourly interest calculation will occur at 2026-04-30 06:00:00 (UTC), with subsequent interest accruing on a full-hour basis for each hourly period.
