Advanced Mortgage Calculator - Financial Planning Guide
Buying a home is the most significant financial decision most people will ever make. Our **Mortgage Calculator** is designed to provide clarity on the true cost of homeownership by providing a detailed breakdown of monthly commitments and long-term interest costs.
How Your Payment is Calculated
A standard mortgage payment is comprised of Principal and Interest. We use the standard amortization formula: `M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]`. By understanding this math, you can see how even a small reduction in your interest rate can save you tens of thousands of dollars over the life of a 30-year loan.
Understanding Amortization
In the early years of a mortgage, the majority of your monthly payment goes toward interest, while only a small portion reduces the actual loan balance (principal). As time goes on, more of each payment is applied to the principal. Use our tool to visualize this transition.
