The choice lies with the lender, while private loans can only require the borrower to pay overdue interest. The borrower pays overdue interest at the interest rate during the loan period stipulated in the contract. For regular private loans, if the borrower fails to repay the loan within the agreed time limit, the specific calculation of interest shall be handled in accordance with the following rules: 1. Regarding the calculation of interest-free loans: there is no agreement on the payment of interest or the agreement is unclear between the parties. , is an interest-free loan.

2. How to calculate loan interest

Loan interest settlement

1. Interest calculation formula: principal times annual interest rate (percentage) times Storage period.

2. Equal principal and interest method:

Calculation formula: monthly repayment = principal times monthly interest rate times [(1-month interest rate)^n/[(1-month interest rate)^ n-1]

In the formula, n represents the number of months of the loan, ^n represents the nth power, such as ^240, which represents the 240th power (loan for 20 years, 240 months)

Monthly interest rate = annual interest rate / 12

Total interest = monthly repayment amount multiplied by the number of loan months - principal

3. Equivalent principal

Calculation formula: monthly Repayment amount = principal rate

Total interest = principal times monthly interest rate times (number of loan months/20.5)

4. Loan interest is generally divided into annual interest rate and monthly interest rate

5. The interest rate is expressed as a percentage, and the monthly interest rate is expressed as a ratio

6. Annual interest rate ÷ 12 = monthly interest rate; monthly interest rate ÷ 30 = daily interest rate; annual interest rate ÷ 360 = daily interest rate.

The calculation formula of loan interest is as follows:

People

Daily interest rate (0/000)=Year 0=Monthly interest rate (‰)÷30

Monthly interest rate (‰) = annual interest rate ()÷12

Banks can use the accumulation interest calculation method to calculate interest:

The accumulation interest calculation method calculates interest based on the actual number of days per day. The daily accumulated account balance, the interest is calculated by multiplying the accumulated points by the daily interest rate.

The interest accrual formula is:

Interest = cumulative interest accrual product multiplied by daily interest rate, where cumulative interest accrual product = total daily balance.

The transaction-by-transaction interest calculation method calculates interest on a transaction-by-transaction basis based on a predetermined interest accrual limit.

If the interest calculation period is a whole year (month), the interest calculation formula is:

①Interest = principal times the number of years (months) times the annual (months) interest rate

If the interest calculation period has a full year (month) and fractional days, the interest calculation formula is:

②Interest = principal rate principal multiplied by the number of fractional days multiplied by the daily interest rate

At the same time, the bank can choose to realize all the interest accrual periods, that is, 365 days per year (three actual days in a leap year, the interest accrual formula is:

③Interest = principal multiplied by the actual number of days multiplied by the daily interest rate

Compound interest: Compound interest is a regulation of the central bank. If the borrower fails to repay the interest within the time stipulated in the contract, compound interest will be charged.

Penalty interest: The lender fails to repay within the specified time limit. The penalty interest imposed on the person who defaults on the contract is called bank penalty interest.

Loan overdue penalty is the same in nature as the penalty interest.

Interest rate calculation formula. Classification:

First, the basic formula for calculating interest is: interest = principal multiplied by the deposit period multiplied by interest rate;

Second, the interest rate, monthly interest rate, and daily interest rate are three The conversion relationship is: annual interest rate = monthly interest rate times 12 (months) = daily interest rate times 360 (days); monthly interest rate = annual interest rate ÷ 12); daily interest rate = annual interest rate ÷ 360 (days) = monthly interest rate ÷ 30 ( days), in addition, the interest rate should be used

Third, the starting point of interest calculation in the interest calculation formula,

1. The starting point of interest calculation for savings deposits is yuan, yuan The following cents do not accrue interest;

2. When actual payment is made, the cents will be rounded to the nearest cent.

3. Except for the annual settlement of current savings, which can transfer the interest to the principal to earn interest, other Regardless of the deposit period, the interest on all kinds of savings deposits will be paid off with the principal when withdrawn, without compound interest;

Fourth, the calculation issue of the deposit period in the interest calculation formula,

1 , Calculate the deposit period by counting the beginning and not the end;

2. Regardless of big months, small months, ordinary months, or leap months, each month is calculated as 30 days, and the whole year is calculated as 360 days. 3. The maturity dates of various deposits are calculated based on the year, month, and day. If the account opening date is a missing date in the expiration month, the end of the expiration month will be the expiration date.

With the continuous development of society, loans are no longer a big deal. They have become a common thing for every household. You can get a loan to buy a house, a car, and even a mobile phone and computer. But the loan is not free and requires us to pay interest. The interest rates vary from bank to bank.

Legal basis:

"People's Republic of China and Civil Code"

Article 680 prohibits usury lending, and the interest rate for borrowing must not violate the state relevant regulations.

If the loan contract does not stipulate the payment of interest, it will be deemed that there is no interest.

If the loan contract does not clearly stipulate the payment of interest, and the parties cannot reach a supplementary agreement, Yuanshen will determine the interest based on local or party transaction methods, transaction habits, market interest rates and other factors; for loans between natural persons, the interest will be deemed to be There is no interest.
