How to Pay Off Your Mortgage Faster (And Save Thousands)

Your mortgage is probably your biggest expense — and your biggest opportunity to save. Because mortgage interest is front-loaded, small extra payments early on can save you more money than you'd ever expect.

Here's exactly how much, and the strategies that work.

Why Extra Payments Are So Powerful

Every extra dollar you put toward your mortgage goes straight to principal — the part that reduces your balance. A lower balance means less interest charged next month, which means more of every future payment goes to principal. It's a snowball effect in your favor.

The Real Numbers: $240,000 at 6.5% for 30 Years

Base payment: $1,517/month, total interest over 30 years: about $306,000.

Now add a small extra payment every month:

Read that again: $100 a month saves you nearly $58,000 and almost 5 years. $200 a month saves you $96,000 and over 8 years. The earlier you start, the bigger the effect, because early payments attack the balance when it's charging the most interest.

4 Strategies to Pay Off Your Mortgage Faster

1. Make One Extra Payment Per Year

Take your mortgage payment and make it 13 times a year instead of 12 — one full extra payment annually. On a typical 30-year loan, this single habit can knock 4–5 years off your term.

2. Switch to Biweekly Payments

Instead of 12 monthly payments, pay half your payment every 2 weeks. You end up making the equivalent of 13 full payments a year, without feeling the hit — because it's spread across the year.

3. Round Up Your Payment

Round your $1,517 payment up to $1,600, or your $2,000 payment to $2,100. The difference is small enough to ignore but adds up to tens of thousands in savings over the life of the loan.

4. Refinance to a Shorter Term

If rates have dropped — or your income has grown — refinancing from a 30-year to a 15-year mortgage dramatically cuts interest. The payment is higher, but you could save six figures in interest.

When NOT to Pay Extra

Extra mortgage payments aren't always the best move. Consider these first:

• High-interest debt — Pay off credit cards (often 18–25%) before a 6.5% mortgage.
• No emergency fund — Keep 3–6 months of expenses liquid before locking money into your house.
• Employer 401(k) match — Never leave free retirement money on the table.

Frequently Asked Questions

Does paying extra go toward principal automatically? Not always — some lenders apply extra payments to future interest or just hold them. Make sure to specify that extra payments go toward principal (and check that they actually did).

How much does one extra payment a year save? On a 30-year mortgage, making one extra payment per year typically saves 4–5 years and tens of thousands in interest, depending on your rate and balance.

Is it better to pay extra monthly or in a lump sum? Monthly extra payments are usually best, because every month you reduce the balance, you reduce the interest charged the following month. A lump sum works too, but earlier is always better.

Should I pay off my mortgage early or invest? It depends on the math. If your mortgage rate is lower than your expected investment return, investing may build more wealth — but paying off the house gives guaranteed savings and peace of mind.
