How to Pay Off Your Mortgage Faster: 8 Strategies Ranked by Real Dollars Saved

The short answer

The fastest way to pay off your mortgage is to send extra money to principal, as early in the loan as possible. On a $400,000, 30-year mortgage at 6.5%, an extra $200 a month saves about $112,000 in interest and pays the house off nearly six years sooner. The method matters far less than two things: how many extra dollars you send, and how early you send them.

Everything below is just different ways of doing that, ranked by what each one actually saves.

Why a 30-year mortgage takes so long

Picture a family that just bought a home with a $400,000 mortgage at 6.5%. Their payment is $2,528 a month for principal and interest.

In the first year, they pay $30,339. Of that, $25,868 goes to interest. Only $4,471 goes toward the house.

That is the 85% problem: in year one of a typical 30-year mortgage, about 85% of every payment goes to the bank, not the home.

It gets better over time, but slowly. After 15 years of on-time payments, this family still owes about $290,000. Half the loan term is gone, and 73% of the balance is still there. By the end of 30 years, they will have paid $510,178 in interest on a $400,000 loan.

Nobody did anything wrong. This is just how amortization works. Interest is charged on the balance you owe, and in the early years you owe almost all of it. So any dollar that knocks down the balance early stops being charged interest for the rest of the loan. That one idea explains every strategy in this guide.

The example we'll use

To keep things fair, every strategy below uses the same loan:

Taxes, insurance, and PMI are left out. They don't change how fast the loan itself gets paid off.

Strategy 1: Add extra to principal every month

This is the simplest strategy and the one most people should start with. Pick an amount, add it to your payment, and tell your servicer to apply it to principal.

Here's what different amounts do to our example loan (we break down more amounts in our guide to extra mortgage payments):

Look at the first row. One hundred dollars a month, the cost of a couple of dinners out, saves almost $64,000. That isn't because $100 is magic. It's because each of those early dollars would have been charged interest for decades.

Good for: almost everyone with steady income and an emergency fund.
Watch out for: make sure the extra goes to principal. Some servicers hold extra money and apply it to next month's payment instead, which saves you nothing.

Strategy 2: Switch to biweekly payments

With biweekly payments, you pay half your monthly payment every two weeks. There are 52 weeks in a year, so you make 26 half payments. That's 13 full payments instead of 12.

On our example loan, that extra payment each year pays the mortgage off in about 24 years and saves roughly $116,000.

Here is the part most articles skip. Biweekly payments work because of the extra payment, not because of the schedule. Paying every two weeks adds about $211 a month in disguise. Compare that to Strategy 1, where an extra $200 a month saved $111,892. Almost the same money, almost the same result.

So biweekly payments are a good habit for people who are paid every two weeks and like matching their bills to their paychecks. It is not a secret.

Good for: people paid biweekly who want the extra payment to happen without thinking about it.
Watch out for: third-party biweekly programs that charge setup or processing fees. Some lenders also hold half payments until the full payment arrives. Ask your servicer how they apply them before you sign up for anything.

Strategy 3: Make one extra payment a year

Same math as biweekly, just in one chunk. Once a year, send one extra full payment straight to principal.

On our loan, one extra $2,528 payment each year pays it off in 24 years and 4 months and saves $111,979.

This works well for people whose income comes in lumps: a yearly bonus, commission checks, or a tax refund. If you can set the money aside all year and send it at once, you get nearly the same result as Strategies 1 and 2.

Good for: people with a yearly bonus or uneven income.
Watch out for: the money has a way of disappearing before the payment date. If that's you, automate Strategy 1 instead.

Strategy 4: Round up your payment

Round your payment up to a clean number. Our example payment is $2,528. Round it to $2,600, an extra $72 a month.

That pays the loan off in 27 years and 8 months and saves $47,805.

It's the smallest change on this list, and it still saves the cost of a new car. Rounding up is the easiest way to start if your budget is tight. You can always raise the number later.

Good for: tight budgets and people who want to start small.
Watch out for: it's slow on its own. Treat it as a starting point.

Strategy 5: Put windfalls toward principal

A windfall is any money that wasn't in your budget: an inheritance, a bonus, a sold car, a tax refund.

Here's the thing about lump sums. When you send the money matters as much as how much you send. Take a single $10,000 payment toward our example loan:

Same $10,000. More than three times the savings when it goes in early. Early dollars do the most work, because they stop interest from compounding on that balance for the longest time.

Good for: anyone who gets irregular money and already has an emergency fund.
Watch out for: money sent to your mortgage is hard to get back. Your home doesn't give you cash in an emergency. Keep three to six months of expenses somewhere you can reach first.

Strategy 6: Recast your mortgage

A recast is when you pay a large lump sum toward principal and your lender recalculates your monthly payment based on the new, lower balance. Your rate and remaining term stay the same. Your payment goes down.

Lenders often require a minimum lump sum, commonly $5,000 to $10,000 or more, and charge a small fee, often a few hundred dollars. Many government-backed loans, like FHA and VA loans, can't be recast.

A recast doesn't pay your loan off faster by itself. It lowers your required payment. But if you keep paying the old, higher amount after a recast, the difference goes to principal, and you get the payoff speed of a lump sum with a safety net: a lower required payment if money ever gets tight.

Good for: people with a large lump sum who want both flexibility and progress.
Watch out for: if you lower your payment and spend the difference, you've traded payoff speed for cash flow.

Strategy 7: Refinance to a 15-year mortgage

Refinancing replaces your current loan with a new one. Moving from 30 years to 15 forces a faster payoff, and 15-year loans usually come with lower rates.

If our example family refinanced $400,000 into a 15-year loan at 6.0%, their payment would rise to $3,375, about $847 more each month. Total interest would drop to $207,577, roughly $302,600 less than the original 30-year loan. That's the biggest number on this list.

But it comes with strings. Closing costs often run 2% to 5% of the loan, which is $8,000 to $20,000 on this one. The higher payment is required every month, good months and bad. And refinancing only makes sense if the rate you can get today works in your favor.

Good for: high, stable incomes, and people whose current rate is above today's rates. For a closer look at both options, see recasting vs. refinancing.
Watch out for: locking yourself into a payment you can't comfortably make. Extra payments on a 30-year loan give you most of the speed with none of the obligation.

Strategy 8: Change how the mortgage is structured

Every strategy above has the same limit. To pay off the house faster, you have to send more money to it.

There is another approach. Instead of adding more money, it changes how your mortgage is set up and how your income moves through it, so less of each dollar goes to interest. That's what Ridgewell's Mortgage Accelerator Program is designed to do. For qualifying households, it is designed to pay off a home in as little as 5 to 7 years, without earning more.

It isn't for everyone. It works best for disciplined households with a real gap between what comes in each month and what goes out. The only way to know if it fits your home is to look at your actual numbers, which is what a free payoff projection does.

Payoff timelines are illustrations for qualifying households and are not guaranteed. Results depend on your income, expenses, balance, and rate.

All 8 strategies, side by side

The pattern is hard to miss. Strategies that cost about the same save about the same. What separates them is how much money goes in and how early.

Before you pay extra: a quick checklist

Paying down your mortgage is a great goal. It is rarely the first goal. Run through this list before you send extra money to your lender.

1. Build an emergency fund first. Three to six months of expenses in a savings account. Your house can't pay your bills if you lose your job.
2. Pay off high-interest debt. A credit card at 22% costs you far more than a mortgage at 6.5%. Clear it first. If you're carrying several balances, the Zero Debt Method is built for exactly that.
3. Get any employer retirement match. If your employer matches 401(k) contributions, that match is an instant return you can't get anywhere else. Paying off the house shouldn't come at the cost of planning for retirement.
4. Check for a prepayment penalty. Most mortgages made since 2014 don't have one. Federal rules limit them to certain fixed-rate loans and only during the first three years. Look at your closing documents or ask your servicer.
5. Tell your servicer where the money goes. Mark extra payments "apply to principal" every time, and check your next statement to confirm it worked.
6. Protect the plan. If your family depends on your income, make sure the mortgage would still get paid if something happened to you. That's what mortgage protection is for.

Is paying off your mortgage early right for you?

There's a real debate here, and both sides have a point.

The case for investing instead (we go deeper in pay off your mortgage or invest): over long periods, the stock market has often returned more than mortgage rates. If your rate is low, the math can favor investing the difference.

The case for paying it down: every extra dollar you send to a 6.5% mortgage is a sure 6.5% in interest you will never pay. No market can promise that. And a paid-off home changes how you feel about money in a way a spreadsheet can't measure. Fewer bills. More choices. Less fear when the economy wobbles.

Most people don't need to pick a side forever. Many do both: save for retirement, and send a steady amount extra to the mortgage. The worst choice is the one most people make by default, which is doing nothing and paying $510,178 in interest without ever looking at the number.

Where to start

Start with one strategy you can actually keep doing. For most people that's a fixed amount added to principal every month, even if it's $100. Raise it when you get a raise. Send windfalls early. Revisit it once a year.

If you want to see what's possible with your own loan, get a free payoff projection from a licensed agent. It's built from your real numbers and takes about 15 minutes.

All examples assume a $400,000, 30-year fixed mortgage at 6.5%, principal and interest only, with figures rounded. The refinance example assumes a new 15-year loan at 6.0% and excludes closing costs. Your results will depend on your loan terms.
