Mathematics — Mortgage

Furthermore, the "math" of mortgages allows for strategic acceleration. By making one extra payment per year—or paying bi-weekly instead of monthly—a borrower can significantly alter the amortization schedule. Because interest is calculated on the remaining balance, any early reduction in principal prevents that specific amount of money from ever accruing interest again, effectively shortening the loan term and reducing the total interest paid. 4.

The Architecture of Interest: An Analysis of Mortgage Mathematics mortgage mathematics

In the early stages of a mortgage, the majority of the monthly payment is directed toward interest. This is because interest is calculated based on the remaining principal. As the principal decreases, the interest portion of the payment shrinks, allowing a larger share of the payment to be applied to the principal. This creates a "snowball effect" where the equity in the home grows at an accelerating rate toward the end of the loan term. 3.
