Extra Mortgage Payment Benefits

Making extra principal payments is one of the most effective ways to build wealth through homeownership. Even small additional payments dramatically reduce interest and shorten your loan term. For example, paying an extra $200 monthly on a $300,000 mortgage at 6.5% can save over $80,000 in interest and cut 7+ years from a 30-year loan.

The impact of extra payments is greatest early in the loan when the principal balance is highest. However, extra payments benefit you at any point. The key is ensuring payments are applied to principal, not held for next month's payment. Most lenders accept online payments with options to specify principal-only payments, or you can mail a separate check marked for principal.

Before making extra payments, ensure you have adequate emergency savings (3-6 months expenses), are maximizing employer 401(k) matches, and have paid off higher-interest debt like credit cards. After meeting these priorities, extra mortgage payments provide a guaranteed return equal to your mortgage rate, which is often better than conservative investments after taxes.

Quick Tips

  • Always compare APR, not just interest rates
  • Use the Rule of 72 to estimate doubling time
  • Extra payments dramatically reduce total interest
