Equal amounts of principal and equal amounts of principal and interest are different repayment methods.

The equal principal amount refers to the equal portion of the total loan amount during the repayment period. A fixed principal is repaid every month. However, if the principal repayment is reduced at any time, the monthly interest paid will also be reduced.

Equal principal and interest is to split the principal and interest into several parts, and repay the same amount of principal and interest every month.

In the two methods of equal principal and equal principal and interest, the principal repayment is the same, but the interest will be different.
