A: According to the insufficient information in the question description, I will assume the following conditions to answer the question:

1. Suppose the loan interest rate is 10% per year.

2. Assume that the loan term is one year.

According to the above assumption, if you borrowed 1000 yuan last year, the interest this year will be 100 yuan (1000 yuan × 10%).

Summary:

According to the hypothetical conditions, if the loan interest rate is 10% and the loan term is one year, the interest-bearing amount after one year is 100 yuan.

Extended data:

-Interest rate and loan term are two important factors that determine loan interest. Under normal circumstances, the higher the interest rate, the longer the loan term, and the amount with interest will increase accordingly. The specific loan scheme may be different, so it is suggested to consult the relevant financial institutions for more accurate interest rate and calculation method.

-The loan interest rate may be different in different countries and regions. Please pay attention to understanding and applying the relevant contents according to the restriction of "non-China information" explicitly mentioned in the question.
