The overdue interest rate for credit cards is uniform, 50,000 per day, and the intraday interest rate is 0.05. It can be calculated based on interest = principal * time * interest rate, as follows:

The interest on a 20,000 credit card overdue for one day = 20,000 * 0.05 * 1 = 10 yuan.

Some credit cards have interest-free periods. If the payment is only one day overdue, the interest will be waived. Please refer to the actual transaction credit card interest rate for specific interest rates.

Overdue loans are also called "overdue loans" or "overdue loans." Refers to the portion of the loan that has not yet been repaid within the repayment period stipulated in the contract. From the overdue date, transfer it to the overdue loan account, and indicate the words "Overdue Loan" at the beginning of the loan account. In order to urge loan units to repay overdue loans as soon as possible, 20% of the overdue portion will be charged interest. The national loan regulations stipulate that if the principal and interest cannot be repaid on time, the retained basic depreciation fund, enterprise fund or profit retained shall be used for repayment, and the cost shall not be included. Take up taxes or sit on profits.

Article 207 of the Contract Law stipulates: "If the borrower fails to return the loan within the agreed time limit, he shall pay overdue interest in accordance with the agreement or relevant national regulations." The abolished Economic Contract Law and Loan Contracts Regulations clearly stipulate the payment of interest on overdue loans and the addition of penalty interest. The 1995 People's Bank of China's "Notice on Interest Calculation Measures after Adjustment of Loan Interest Rates" (hereinafter referred to as the "Notice") and the 1999 "RMB Interest Rate Management Regulations" (hereinafter referred to as the "Regulations") have relatively detailed regulations on the calculation and collection of overdue loan interest, and the Supreme People's Court has issued corresponding approvals on such issues.

According to the above provisions and based on the actual trial, there are two main ways to calculate overdue loan interest:

First, it is calculated according to the agreed interest rate during the contract period. During the performance period stipulated in the loan contract, the interest rate paid by the borrower can be calculated according to the interest rate agreement as long as it does not violate the People's Bank of China's regulations on the upper and lower limits of loan interest rates for financial institutions, and private loans are not higher than 4 times the bank loan interest rate. Overdue interest on overdue loans.

The second is to calculate interest in accordance with the relevant regulations of the People's Bank of China. In this interest calculation method, the loan interest rate during the performance period of the loan contract will still comply with the original agreement, and interest will not be calculated in stages if the interest rate is adjusted. For overdue loan interest rates, the interest rate will be adjusted in stages according to the interest rates determined by the People's Bank of China in different periods. Overdue interest is calculated based on the segment interest calculation method. While collecting overdue interest, penalty interest is charged at a certain proportion, or the penalty interest is calculated in segments according to the overdue loan penalty interest rate determined by the People's Bank of China and the penalty interest is adjusted.

At the same time, interest will be settled on a quarterly basis for loans within the contract performance period and after overdue (short-term loans within one year can also be settled monthly), and the interest settlement date for each quarter is the 20th of the last month of the quarter. If the borrower cannot pay the interest on time, the interest will be compounded.

Among the above two interest calculation methods, the former is generally applicable to private loans, while the compound interest calculation and collection in the latter interest calculation method is not applicable to private loans. The latter method is generally applicable to bank loan contracts, and the former method of calculating interest is not prohibited by law.

Both interest calculation methods have their own characteristics. Calculating and collecting overdue interest according to the agreement can fully reflect the principle of autonomy of the parties to the contract within the scope of the law and the calculation method is simple. However, if the overdue period is long, When the national interest rate adjusts significantly, the interest may be calculated too high or too low, which violates the spirit of fair civil law. Overdue loan interest is calculated and charged in accordance with the relevant regulations of the People's Bank of China, although it can appropriately reflect the interest payable on overdue loans. , but the implementation process is too cumbersome.
