1, average capital

Total interest = (number of periods 1)× total loan × monthly interest rate ÷2,

Monthly payment for each installment = monthly principal payable and monthly interest payable,

Monthly repayable principal = total loan amount, number of installments,

Monthly interest payable = [total loan-monthly principal payable (current period-1)] monthly interest rate,

Monthly interest rate = annual interest rate12 months.

2. Equal principal and interest

Total interest = monthly installment-loan principal,

Monthly repayment amount of each installment = [total loan amount × monthly interest rate ×( 1 interest rate) installment ]=[( 1 interest rate) installment-1],

Where ""stands for power, which is an operation mode in mathematics. For example, 2 12 means that the number 2 needs to be multiplied by 12 times repeatedly. You can do it yourself with a calculator and other tools.

Secondly, an example is given to illustrate the calculation process.

Assuming that the total loan amount is 240,000, the loan term is 20 years, that is, the loan will be repaid in 240 installments, with the annual interest rate of 4.8%, and the principal will be repaid in equal amount, then:

1, monthly interest rate = 4.8%12 months =0.4%,

2. Monthly payable principal = 240,000 ÷ 240 =11,000 yuan,

3. Total interest = (2401) 2400000.4% ÷ 2 =115680 yuan,

4. The first month =1000 (240000-10000) 0.4% =1960 yuan,

5. Monthly payment in the second month =1000 (240000-10001) 0.4% =1956 yuan.

6. The third monthly payment =1000 (240000-10002) 0.4% =1952 yuan,

How to calculate the monthly repayment details of mortgage calculator

Starting from the monthly contribution, the bank collects the interest on the remaining principal first, and then the principal; The proportion of interest in monthly payment decreases with the decrease of residual principal, and the proportion of principal in monthly payment increases with the increase, but the total monthly payment remains unchanged.

To use the detailed monthly mortgage payment calculator:

Step 1: First, choose whether your repayment method is average capital or equal principal and interest, and fill in the commercial loan term, loan amount and actual loan interest rate;

Step 2: Select whether to display repayment details, and click "Calculate" to get detailed information such as monthly repayment amount, total loan interest, total repayment amount, etc.

Tip: Half-year and one-year loans usually use one-time repayment of principal, and interest = loan amount and loan interest rate, which is not applicable to this calculator.

Extended data:

(1) The interest rate conversion formula for RMB business is (note: common for deposits and loans):

1. daily interest rate (0/000)= annual interest rate (%)÷360= monthly interest rate (‰)÷30.

2. Monthly interest rate (‰) = annual interest rate (%)÷ 12

(two) banks can use the product interest method and the transaction interest method to calculate interest.

1. Accumulate the account balance daily according to the actual number of days, and multiply the accumulated product by the daily interest rate to calculate the interest. The interest-bearing formula is:

Interest = cumulative interest-bearing product × daily interest rate, where cumulative interest-bearing product = total daily balance.

2. Transaction-by-transaction interest calculation method calculates interest one by one according to the preset interest calculation formula: interest = principal × interest rate × loan term, with three details:

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

① Interest = principal × year (month )× year (month) interest rate

If the interest-bearing period is a whole year (month) and days, the interest-bearing formula is:

② Interest = principal × year (month) × year (month) interest rate principal × odd days × daily interest rate.

At the same time, banks can choose to convert all interest-bearing periods into actual days to calculate interest, that is, 365 days per year (366 days in leap years), and each month is the actual number of days in the Gregorian calendar of the current month. The interest-bearing formula is as follows:

③ Interest = principal × actual days × daily interest rate

These three formulas are essentially the same, but because the interest rate conversion is only 360 days a year, when calculating the actual daily interest rate, it will be calculated as 365 days a year, and the result will be slightly biased. Which formula is used specifically, the central bank gives financial institutions the right to choose independently. Therefore, the parties and financial institutions can agree on this in the contract.

(3) Compound interest: Compound interest means adding interest at a certain interest rate. According to the regulations of the central bank, if the borrower fails to repay the interest at the time agreed in the contract, it will be charged with compound interest.

(4) Penalty interest: If the lender fails to repay the bank loan within the prescribed time limit, the penalty interest paid by the bank to the defaulter according to the contract signed with the parties is called bank penalty interest.

(V) loans overdue liquidated damages: penalties for the defaulting party with the same nature as penalty interest.
