A mortgage is likely the largest debt you will ever take. Understanding how the amortization system works is crucial for making smart financial decisions that could save you tens of thousands of dollars.# The "Trap" of Front-Loaded Interest: Understanding Your Payment Breakdown
In most countries, mortgages use the standard amortization system. Its characteristic is that your monthly payment remains the same (if fixed rate), but the composition changes dramatically over time.How Your Payment Evolves
Early Years (Years 1-10): You pay almost entirely INTEREST and very little principal. On a $250,000 mortgage at 3%, your first payment could be 80% interest.
Middle Years (Years 11-25): The proportion gradually balances.
Final Years (Years 26-30): You pay almost entirely PRINCIPAL with very little interest.
