Average capital repayment method is a very simple and practical repayment method. The principle of the basic algorithm is to repay the loan principal in equal amount on schedule during the repayment period, and at the same time pay off the interest generated by the unpaid principal in the current period. Repayment methods can be monthly repayment and quarterly repayment. The calculation formula is as follows:

Monthly repayment amount = loan principal ÷ months of loan term (principal-accumulated amount of repaid principal) × monthly interest rate.

If the loan is 45,000 yuan and the loan period is 5 years, for example:

Repay the principal in equal amount every month: 45,000 ÷ (5×12) = 750 yuan.

Interest of the first month: 45,000× (5.58% ÷12) = 209.25 yuan.

The repayment amount in the first month is 750,209.25 = 959.25 yuan;

Interest of the second month: (45,000-750×1)× (5.58% ÷12) = 205.76 yuan.

The repayment amount in the second month is 750,205.76 = 955.76 yuan.

It can be seen that with the continuous repayment of the principal, the interest on the outstanding principal in the later period will be less and less, and the monthly repayment amount will gradually decrease.

This method was introduced in June 1999 1 and is being gradually adopted by banks.

The equal principal and interest method is relatively simple.

Two, the bank loan interest calculation except 365 days or 365 days?

The calculation of bank loan interest, except for 360 days, does not calculate 365 days:

So as to facilitate calculation;

There are 12 months every year, and every month is exactly 30 days according to 360 days.

There are two algorithms for bank loan interest: 360 days and 365 days;

Annual interest rate of general loans;

The daily loan interest rate is converted into the adult loan interest rate by 365 days.

Third, how to calculate the interest on bank loans?

Matching principal and interest calculation formula: [loan principal × monthly interest rate ×( 1 interest rate) repayment months ]≤[( 1 interest rate) repayment months-1] average fund calculation formula: monthly repayment amount (loan principal ÷ repayment months) (principal-accumulated amount of repaid principal) ×
