How to calculate the interest of BYD Qin car loan and bank loan? For borrowers, of course, the biggest concern is interest. So, how to calculate the loan interest? According to the actual situation, the amount of loan interest mainly depends on the loan interest rate of various lending institutions (generally floating within the interest rate range stipulated by the central bank) and repayment methods. Due to different repayment methods, such as average capital repayment method and average capital repayment method, the monthly loan interest is different. But no matter what loan method, there is a standard and unified calculation rule for loan interest.

Standard formula for calculating loan interest:

Loan interest of the current month = monthly interest rate of the remaining principal loan of the previous month;

Principal paid in the current month = repayment amount in the current month-loan interest in the current month;

Remaining principal of last month = total loan-accumulated principal repayment;

So, how to calculate the loan interest? Below we can according to a practical example to illustrate:

If borrower A borrows RMB 654.38+million from XX Bank for three years, the monthly loan interest rate is 0.5 125% based on the latest loan interest rate of 20 13 (the current annual interest rate of three-year loans is 6. 15%). So,

First month loan interest =100000.5125% = 512.5;

Principal paid in the first month = repayment amount in the first month (depending on repayment method)-521.5;

Residual principal in the first month = 100000- (repayment amount in the first month-521.5);

Loan interest in the second month = {10000- (repayment amount in the first month -52 1.5)} 0.5 125%. ...

Then calculate the monthly loan interest by analogy until the repayment is completed (the loan expires).
