Whether it is the equal principal and interest repayment method or the equal principal repayment method, the essence of interest will not change. Interest rates are determined by the collective impatience of countless people. Due to impatience, that is, impatience, people always want to enjoy it early, so the exchange of "spot" and "futures" occurs; it is precisely because of impatience that the farther away "futures" are from today, the lower their value.

Therefore, in order to achieve a transaction between "spot" and "futures", the quantity of "futures" must be larger than the quantity of "spot", and the difference determines the level of interest rates. The amount of interest, if the interest rate remains unchanged, can only be determined by the actual occupation time and amount of the funds, rather than which repayment method is used.

Different repayment methods are only designed to meet the different needs or consumption preferences of people with different incomes, different ages, and different consumption concepts.
