The biggest feature of the equal principal and interest repayment method in the average capital repayment method is that the repayment principal amount in the monthly (installment) repayment is equal, which is equal to the total loan divided by the loan period (or the total number of months). However, the monthly interest repayment decreases with the decrease of the principal. So the monthly repayment amount decreases month by month. 1. Calculate the monthly repayment amount with the formula. The formula is, if the above formula is expressed in words, it is the repayment amount of the current month = principal/total number of loans+principal × [1-number of previous periods/total number of loans ]× monthly interest rate. Example 2. When the total loan amount is 200,000 yuan, the annual interest rate is 7.05% and the repayment period is 654,300 yuan. Answer: the monthly interest rate α=7.05% ÷ 12 = 0.005875, and the first month's principal repayment = 200,000 yuan ÷1666.67 yuan. Therefore, ① the repayment amount in the first 1 month = 200,000 yuan/120+200,000× 0.005875 =1666.67 yuan+175 yuan = 284/kloc. ② 66th month.

Equal increase or decrease repayment method

The equal increasing (or decreasing) repayment method is also called equal progressive repayment method. The so-called equal increase (or decrease) repayment method is developed on the basis of equal principal and interest repayment method. This method is characterized by dividing the repayment period into two or several stages, and the repayment amount of each stage is different. Can be incremental; It can also be decreasing. For example, when a small white collar who has just joined the work wants to buy a house, he can choose to increase by an equal amount; If you are older, it is expected that there will be pressure such as children going to school in the future, you can consider choosing the equal decreasing method.

All banks have calculators designed for this purpose. Just enter the following parameters.

① loan amount; ② loan term; ③ Annual loan interest rate; (4) from which period began to change; ⑤ Change it every few periods; ⑥ Amount of each increase or decrease.

Equal ratio increasing (or decreasing) repayment method

Equal ratio increasing (or decreasing) repayment method is also called equal ratio progressive repayment method. The so-called equal ratio increasing (or decreasing) repayment method is developed on the basis of equal principal and interest repayment method. This method is characterized by dividing the repayment period into two or several stages, and the repayment amount of each stage is different. Can be increased in proportion; It can also be reduced in proportion.

All banks have calculators designed for this purpose. You only need to enter the following parameters to give the answer immediately. These parameters are:

① loan amount; ② loan term; ③ Annual loan interest rate; (4) from which period began to change; ⑤ Change it every few periods; ⑥ The ratio of the adjusted amount to the amount before adjustment.
