The loan interest of rural credit cooperatives varies according to the length of the loan period. If the loan time unit is days, the expected annualized interest rate is monthly interest: loan interest = loan principal × loan time (days) × expected annualized interest rate/12. If the loan time unit is days, the expected annualized interest rate is the annual interest rate: loan interest = loan principal × loan time (days) × loan expected annualized interest rate /360.

For example, a loan of 50,000 yuan, one-year repayment, how much interest?

One year: 50,000 * interest rate+principal prepayment: actual days/365 * 50,000 * interest rate+principal.

1, one-year repayment, and the loan interest rate of rural credit cooperatives is 6.3 1%.

2. A year is calculated as 365 days. According to the calculation formula: if the loan time unit is days, the expected annualized interest rate is annual interest rate: loan interest = loan principal × loan time (days) × loan expected annualized interest rate /360.

Then the monthly interest rate is 50000× 365× 6.31%/360 = 3198.82 yuan.
