How to Pay Off Your Mortgage 10 Years Early

On a $300,000 mortgage at 6.5% for 30 years, your standard monthly payment is $1,896. You will pay $382,633 in total interest over the life of the loan — more than the house itself. But by adding extra payments to your principal each month, you can cut years off the loan and save tens of thousands in interest. Here is exactly how much each extra payment level saves.

Extra $200 per month: You pay off the mortgage in approximately 23 years instead of 30 — saving 7 years. Total interest paid: $290,400 instead of $382,633. Interest saved: $92,233. Extra $500 per month: Payoff in approximately 18.5 years — saving 11.5 years. Interest paid: $222,800. Interest saved: $159,833. Extra $1,000 per month: Payoff in approximately 14 years — saving 16 years. Interest paid: $162,400. Interest saved: $220,233. The results are dramatic because extra payments go entirely toward principal reduction, which reduces the base that interest accrues on for every remaining month. Use the [loan payoff calculator](/calculators/loan-payoff) to run the exact numbers with your specific mortgage balance, rate, and extra payment amount.

The biweekly payment hack is the easiest way to make extra payments without feeling the pain. Instead of paying $1,896 once a month, you pay $948 every two weeks. Since there are 26 biweekly periods per year (not 24), you end up making 13 full monthly payments per year instead of 12 — one extra payment annually without changing your budget. On a $300,000 mortgage at 6.5%, biweekly payments save approximately $68,000 in interest and pay off the loan about 5 years early. Call your lender to set this up — some charge a fee, but many do it for free.

The one-time lump sum strategy can be combined with regular extra payments for faster results. Directing your tax refund ($3,000 average), annual bonus, or inheritance directly to your mortgage principal accelerates payoff. A one-time $10,000 principal payment in year 5 of a $300,000 mortgage saves approximately $25,000 in interest over the remaining life of the loan. The earlier in the mortgage you make lump sum payments, the more interest you save because the money has more years of compounding to prevent.

When you should NOT pay off your mortgage early: if your mortgage rate is below 5% and you could invest the extra payment money at a higher return. On a 3.5% mortgage, paying $500 extra per month saves $159,833 in interest over the life of the loan. But that same $500 per month invested at 8% for 18 years grows to approximately $240,000 — an $80,000 better outcome than early payoff. The math clearly favors investing over early payoff when your mortgage rate is low. However, at 6.5%+ rates (common in 2026), the gap narrows significantly and early payoff becomes competitive with investing, especially when you factor in the guaranteed return of debt elimination versus the uncertain return of the stock market.

Critical details about extra payments: always specify that extra money goes to principal, not to advancing your next payment date. Some lenders apply extra payments to future payments by default, which does not reduce your interest the same way. Call your lender or check the payment portal for a field labeled "additional principal" or "extra principal." Also confirm that your mortgage has no prepayment penalty — most conventional loans do not, but some older loans and certain adjustable-rate mortgages charge a fee for early payoff.

The refinancing alternative: if you are currently at 7% or higher, refinancing to a lower rate can save more than extra payments. Refinancing from 7% to 6% on a $280,000 balance reduces your monthly payment by approximately $200 and saves over $70,000 in total interest. The breakeven point for refinancing costs (typically $3,000 to $7,000 in closing costs) is usually 12 to 24 months. If you plan to stay in the home for 3+ more years, refinancing at a meaningfully lower rate is almost always worth it.

Use the [loan payoff calculator](/calculators/loan-payoff) to model your specific mortgage with any extra payment amount. It shows your new payoff date, total interest saved, and months eliminated. Then decide whether the extra payments or investing gives you a better outcome based on your rate.

Frequently Asked Questions:

Should I pay extra on my mortgage or invest? If your rate is above 6%, paying extra is competitive with investing. Below 4%, investing almost certainly wins. Between 4 and 6%, it depends on your risk tolerance — debt payoff is guaranteed, investing is not.

How do I make extra mortgage payments? Most lenders allow extra payments through their online portal. Look for an "additional principal" field. You can also mail a separate check marked "apply to principal only."

Does paying extra on my mortgage help my credit score? Indirectly. Reducing your mortgage balance improves your credit utilization on installment loans, but the effect is smaller than credit card utilization. It will not hurt your score.

Can I pay off my mortgage with a lump sum? Yes, most mortgages allow full or partial prepayment at any time. Contact your lender to request a payoff amount, which includes any accrued interest to the payoff date.

Is a 15-year mortgage better than a 30-year with extra payments? A 15-year mortgage typically has a lower interest rate (0.25 to 0.75% less), saving more overall. But the required payment is higher with no flexibility. A 30-year with extra payments gives you the flexibility to reduce payments during tough months while still paying off early.
