1. Calculate the monthly repayment principal first: 50,000/36 =1388.9 yuan.

As for the interest, you didn't say it here. I'll calculate it for you according to the bank's interest rate of 0.8% a month, for reference only. Finally, the actual interest rate shall prevail: 50,000 x 0.8% = 400 yuan.

3. Based on the above, the monthly repayment amount is:1388.9+400 =1788.9 yuan; The above interest rates are for reference only, and finally your actual loan interest rate is the main one. The calculation method is basically like this.
