How does a 30-year fixed mortgage amortize over time in terms of principal vs interest?

• A. Early payments allocate more to interest; as time passes, a larger portion goes to principal, gradually reducing balance.
• B. Principal is paid first; interest declines later.
• C. Principal and interest split constant throughout.
• D. Interest is constant and principal decreases to zero quickly.

Answer: (D)

In a 30-year fixed-rate mortgage the monthly payment stays the same, but how that payment is divided between interest and principal changes over time. At the start, most of each payment goes toward interest because the loan balance is high, so the interest charge is large. As you keep making payments and the balance drops, the interest portion of each payment shrinks, and more of the same fixed payment goes toward reducing the principal. This gradual shift continues until the loan is paid off, and equity builds as more principal is paid later in the term. So, the statement that early payments allocate more to interest and later payments apply more to principal best describes the amortization pattern. The idea that principal is paid first, that the split remains constant, or that interest stays the same while principal drops quickly does not match how fixed-rate mortgages actually amortize.
