A home loan amortization calculator shows how your fixed monthly payments gradually reduce your mortgage balance over time until it reaches zero. In the United States, most mortgages are fully amortizing, meaning each payment covers both interest and principal. Early in the loan, a larger share goes toward interest; later, more goes toward principal. Our 2026 calculator updates for current rates and lets you model real-life scenarios like extra payments or refinancing.
