What is the relationship between interest and principal payments in an amortized loan over time?

In an amortized loan, the structure of payments usually shifts over time, impacting the relationship between principal and interest. The correct understanding is that principal payments increase while interest payments decrease as the loan is paid down.

At the beginning of an amortized loan term, the outstanding principal balance is larger, which means that the interest calculated on that balance is also higher. As you make payments, a larger portion of those payments initially goes towards interest. However, as you continue to make payments, the principal balance decreases, leading to a reduction in the interest charged for each subsequent payment.

Consequently, a greater share of each payment can go towards paying down the principal. This results in increasing principal payments and decreasing interest payments throughout the life of the loan, demonstrating the reversed relationship between these two components over time. Understanding this dynamic is crucial for effective financial planning and strategy when managing loans.
