1. Quarterly repayment amount = loan principal ÷ number of quarters of loan term+(principal-accumulated repayment amount of principal) × quarterly interest rate.
Second, introduce specific calculation examples, such as taking the loan of 200,000 yuan and the loan term of 10 year as an example:
① Repay the principal in equal amount every quarter: 200,000 ÷ (10× 4) = 5,000 yuan.
② Interest in the first quarter: 200,000× (5.58% ÷ 4) = 2,790 yuan.
③ The repayment amount in the first quarter is 5000+2790=7790 yuan;
④ Interest in the second quarter: (200,000-5,000×1)× (5.58% ÷ 4) = 2,720 yuan.
⑤ The repayment amount in the second quarter is 5000+2720=7720 yuan.
According to the above formula, specific repayment data can be obtained, and by analogy, the specific situation of each year can be calculated.
