Mortgage Amortization Calculator – Calculate Your Home Loan Payment Schedule
Buying a home is one of the biggest financial commitments most people make. This Mortgage Amortization Calculator helps you understand exactly how your mortgage is repaid over time by generating a detailed payment schedule. You'll see how much of each payment goes toward reducing your loan balance and how much is paid as interest, giving you a clearer picture of the true cost of your mortgage.
See Where Your Mortgage Payments Go
Many homeowners are surprised to learn that the first years of a mortgage are heavily weighted toward interest payments. This calculator shows how that balance gradually shifts as your loan matures. It also lets you experiment with additional monthly payments so you can estimate how much sooner you could become mortgage-free.
Example: If you borrow $350,000 over 30 years at a 6.25% interest rate, adding an extra $150 per month could reduce your total interest costs and shorten the repayment period by several years.

Important Assumptions
This calculator estimates payments using a fixed interest rate throughout the loan term. It does not automatically include property taxes, homeowners insurance, HOA fees, mortgage insurance (PMI), or lender-specific charges. If you have an adjustable-rate mortgage (ARM), your future payments may differ from the estimates shown here.
Ways to Save on Your Mortgage
Even small extra payments can make a noticeable difference over the life of your loan. Before increasing your payments, confirm that your lender applies additional funds directly to the principal and does not charge prepayment penalties. Comparing a 15-year and 30-year mortgage within the calculator can also help you understand the trade-off between lower monthly payments and long-term interest costs.
