2 Extra Mortgage Payments a Year: How Much Will You Save?

You have some disposable income — maybe it's a year-end bonus, a tax refund, or cash that came from somewhere unexpected — and you're looking at your mortgage and wondering whether throwing it at the balance is the smart move. What you want to know is what two extra payments a year would do to your loan, and whether it beats putting that money somewhere else.

On a $347,280 loan at 6.67% (August 2026), making the equivalent of two extra payments a year (about $372 more each month) saves roughly $169,700 in interest and retires the loan in 20 years and 4 months instead of 30, close to nine years and eight months early.[1]

That's real money. But how much you'd save depends almost entirely on your interest rate, and whether you should do it at all depends on things that have nothing to do with your mortgage.

So this comes down to the math and the decision. Extra money does nothing to your balance unless you tell your servicer to apply it to principal. Get that wrong and you've simply paid next month's bill early.

Run the numbers: Two extra mortgage payments a year

Plug your own details into our calculator below, which offers a few options: Making a single lump-sum extra payment, making regular lump-sum extra payments, and adding additional principal to your loan each month.

This can help you see how adding both one or two extra payments a year, plus inflating your regular monthly payments, can give you extra payoff power. That's not always feasible for every borrower, but if it might be for you, it's worth playing with the numbers to see how you could be giving your future self a little more financial wiggle room.

What happens when you make two extra payments a year

A mortgage is front-loaded with interest. Early in the loan your balance is high, so most of each payment covers interest and only a sliver chips away at principal; over time that split flips, and the later payments are mostly principal.[2] When you send an extra dollar and mark it for principal, you erase every future interest dollar that balance would have generated. That's why a modest amount, applied early and consistently, compounds into a large number by the end.

There's a moment of panic worth heading off here, because it's common and it makes people quit. You make a big principal payment, check your balance, and it barely seems to move. One homeowner on a personal finance forum described being disheartened that three separate $10,000 payments had reduced principal by only about $3,500 on paper.

The usual culprit is a mix-up between your full monthly bill and the part that pays down the loan. Your payment likely includes property taxes and homeowners insurance held in escrow, and only the principal-and-interest portion touches your balance.[2] So when you send extra, make sure it's landing on principal, not padding your escrow account or sitting as a prepaid payment. Once it's applied correctly, the balance moves exactly as the math dictates.

For the rest of this piece, picture a specific loan so you can track the impact. Say you buy a $434,100 home, close to the national median, and put 20% down.[3] That leaves a $347,280 loan on a 30-year fixed interest rate at 6.67%, with a principal-and-interest payment of about $2,234 a month.

"Two extra payments a year" isn't one method; it's a target you can hit three ways. You can add about $372 to every monthly payment, which spreads the two extra payments evenly across the year. You can send one lump sum of roughly $4,468 once a year, often from a bonus or tax refund. Or you can split it however your cash flow allows. The result is the same total; the timing differs slightly, which the next sections get into.

How much do two extra payments a year save?

For the example loan, the answer is about $169,700 in interest saved and a payoff in 20 years and 4 months. The table below runs a range of extra monthly amounts against that same loan so you can see how the savings scale.

How we calculated this: These figures use standard fixed-rate amortization on a $347,280 loan (a $434,100 home with 20% down) at a 6.67% fixed rate, the Freddie Mac 30-year average for the week of Aug. 13, 2026.[1] They cover principal and interest only, and exclude property taxes, homeowners insurance, PMI, and HOA dues. Extra payments are applied to principal starting in month one, and the rate is held constant for the life of the loan. Change any input, especially your rate or how many years you have left, and your numbers will move. Analysis by Clever Real Estate.

A couple of things stand out. Even $25 a month, less than a streaming bundle, shaves a full year off the loan and saves close to $19,000. And the returns aren't linear: doubling your extra payment doesn't double your savings because you're compressing the loan into its high-interest early years. These are estimates on one specific loan; the calculator above can help you determine what the impact would be on your loan.

Does 'one extra payment a year' really pay off your house 7 years sooner?

The short version: not at the rates most people carry. How many years you shave off is almost entirely a function of your interest rate, and the popular "you'll pay it off seven years earlier" figure describes a higher-rate loan than the typical homeowner has today.

Run one extra payment a year against the example loan at different rates, and the pattern is clear. At 3% you save about 3.5 years. At 5%, roughly 4.7 years. At 6%, about 5.4 years. You don't reach a full seven years until around 8%, and you'd need a rate closer to 10.5% to get to nine-plus. At August 2026's 6.67%, one extra payment a year cuts about 5.9 years off a 30-year loan.

Two extra payments a year, which is what this article is about, roughly doubles that effect. On the example loan at 6.67%, two extra payments cut about 9.7 years, which is why the "pay it off almost a decade early" framing holds up here even when the seven-years-from-one-payment claim doesn't.

How to make sure your extra payment counts

Getting this right takes three steps.

Step 1: Tell your servicer it's for principal

An extra payment sent with no instructions can be parked as a prepaid future payment or dumped into escrow instead of reducing your balance. You have two clean ways to prevent that. On a paper check, write it in the memo line. Online, most servicer portals let you direct the money yourself.

As Adam P. Smith, president of The Colorado Real Estate Finance Group, describes it: "You're absolutely making sure that your check memos read 'toward principal only.' When I go to pay my mortgage online, I can decide where the money is being allocated. Do I want to make an additional payment? How much? Do I want it to go into my escrow account or toward the principal balance?"

If your portal doesn't offer that choice, call your servicer and ask how to designate principal-only payments.[2]

Step 2: Know what happens if you don't follow step 1

When money arrives without instructions, servicers don't all handle it the same way, and some will credit it toward your next payment rather than your principal. Tony Davis, CEO of Lendtrain and managing partner at Atlantic Home Mortgage, explains: "Sometimes the servicer applies the payment as prepaid payment(s) for future months instead of a principal payment. If this happens, contact your servicer and they can help you fix it. Every servicer is different, so check with yours before making extra payments."

The good news is that it's fixable with a phone call. The bad news is that nobody calls you to flag it, so the responsibility is yours.

Step 3: Verify on a schedule

Confirming once isn't enough because the misapplication can happen on any payment. Des Cooney, a financial consultant at Axis Financial Consultants, builds a routine around it: "To avoid delays, I encourage my clients to reach out to their lender or servicer once per quarter and ask them to verify which account is holding the payment." A quarterly check-in takes a few minutes and catches problems while they're small, instead of months later when the fix is a headache.

A quieter trick worth knowing: push, don't pull. Smith also suggests setting up your extra payments so your bank pushes the money to the servicer, rather than authorizing the servicer to pull it from your account. It keeps you in control if you ever refinance or switch servicers, when an automatic pull can misfire during the handoff.

On most loans today, prepayment penalties don't apply to the kind of extra principal we're talking about. Penalties typically kick in only when you pay off the entire loan by selling or refinancing within the first three to five years, and they generally don't apply to small extra principal payments, though the CFPB advises confirming with your lender.[4] Federal rules also cap and phase them out: Under the Ability-to-Repay/Qualified Mortgage rule, a penalty can't exceed 2% of the balance in the first two years or 1% in the third, and is prohibited after that.[4] It's still worth taking a look at your own loan documents, especially if you have a non-conforming loan.

Monthly vs. annual vs. biweekly: which method?

Once you've decided to pay extra, the "how" matters less than you might think, but a little more than nothing. Spreading the money out earns you a bit more than making one or two payments a year because every dollar you send earlier stops accruing interest sooner.

On the example loan, splitting two extra payments across 12 months leaves you paying about $287,200 in interest and finishes in 20 years and 4 months. Sending the same amount as one annual lump sum runs about $293,100 in interest and finishes three months later, in 20 years and 7 months.

The gap is roughly $5,800 and a quarter over two decades. Earlier is better, so if you can spare a little every month, do that. If a once-a-year bonus is the only way you'll reliably do it, the annual route still gets you almost all the way there. Don't let the perfect method stop you from using the one you'll stick to.

Where you should be careful of is a biweekly payment program, especially one your servicer offers to set up for you. The pitch is appealing: pay half your mortgage every two weeks, and because there are 52 weeks in a year, you make 26 half-payments, or 13 full payments, sneaking in one extra a year without feeling it. The problem is the fee. Cooney has seen exactly what that costs: "Many lenders charge a fee, which varies depending on the servicer, to set up and administer these programs. For example, one of our large banks charges $15 per month."

Fifteen dollars a month is $180 a year, and on a 20-year payoff that's roughly $3,600 to accomplish something you can do yourself for free.

You don't need the program to get the result. Davis prefers the do-it-yourself version, and he's a lender steering you away from a lender-sold product: "I prefer the DIY version: add 1/12 of the regular principal-and-interest payment each month and mark it 'principal only.' It achieves the same thing, which is one extra payment a year, without a program fee. Some servicers will hold a half-payment in suspense until the rest arrives." That suspense-account risk is the other reason to be wary of biweekly setups: a half-payment sitting in limbo isn't reducing anything until its other half shows up.

There's a persistent debate about whether mortgage interest accrues daily or monthly. For most conventional loans, interest is figured monthly based on your balance at the start of each billing cycle. In practical terms, that means "pay earlier" pays off across billing cycles, not day by day within a month, so you don't need to obsess over sending your extra payment on the 3rd versus the 20th. Getting it in before the cycle closes is what counts.

And realistically, most people fund these payments from a windfall like a bonus or tax refund rather than by squeezing their monthly budget, so pick the cadence that matches when the money shows up.

Should you make extra payments? Start with your rate

Before the mechanics comes the decision, and the decision starts with a single number: your interest rate. The cleanest way to think about prepaying is that it's a guaranteed tax-free return equal to your rate. Every dollar you put toward a 6.67% mortgage is a dollar that "earns" you 6.67%, risk-free by erasing future interest. Compare that to a high-yield savings account paying somewhere around 4% to 4.5% right now, and prepaying looks strong.

So the threshold is really about what else your money could do. At 6% or higher, a guaranteed return in that range is hard to beat on a risk-adjusted basis, and prepaying makes a lot of sense. Down in the 3% to 4% range, the case falls apart because even a plain savings account or short-term Treasury can top that, and the money works harder elsewhere. In between is a judgment call.

It's worth being clear-eyed about the comparison people usually reach for: the stock market. Over the long run the S&P 500 has returned roughly 10% a year before inflation, or about 7% after it.[5] That beats a 6.67% mortgage on paper, but notice the asymmetry: The stock return is a long-run average with real risk and no guarantee in any given year, while the mortgage return is locked in.

Even when the rate math favors prepaying, it shouldn't always be the first way you decide to spend your money. Davis is blunt that it sits far down the priority list, and Cooney sequences it the same way from the planning side: "First and foremost, we focus on building or protecting their emergency fund. Then we help them capture any available employer retirement matching and eliminate high interest debt. Finally, once they have completed these steps, I recommend directing any remaining funds toward either investing or paying down their mortgage, or both if possible."

The emergency fund comes first for a reason. A common guideline is three to six months of expenses, and it's a cushion most households don't have: in the Federal Reserve's 2025 survey, only 55% of U.S. adults said they had rainy-day funds covering three months.[6] Money locked in your home's equity can't cover a job loss or a roof.

That liquidity point is the strongest argument against getting aggressive with prepaying your mortgage, and it's worth hearing from someone who watched it go wrong. Davis, who has originated more than a billion dollars in loans over two decades, would rather keep his cash accessible even when the numbers are a wash: "Even if you're only making 6% in your investment account and you have a 6% mortgage, personally, I'd rather break even and keep the liquidity. I saw a lot of people get torched in 2008 because all their savings was in their home equity, until it wasn't. A house is really just a large, illiquid asset." His shorthand: don't pinch dollars to save pennies.

One more thing, and it's the part spreadsheets miss. Being mortgage-free carries a weight that doesn't show up in a savings figure. For a lot of people, owning their home outright is worth accepting a slightly lower theoretical return, and there's no shame in that.

There's also a practical version of the same point: prepaying is often the better real-world move for someone who wouldn't reliably invest the difference. The math that says "invest instead" only works if you do in fact invest it, and month after month, most people spend it. If that's you, a mortgage you're steadily paying down beats an investment account you keep meaning to fund.

Pros and cons of extra mortgage payments

Weighing both sides makes the decision easier to live with.

The prepayment penalty risk is small and mostly limited to certain non-conforming loans, since federal rules cap and phase out penalties on most mortgages.[4] And the shrinking mortgage-interest deduction only matters if you itemize, which most filers don't. For 2026 the standard deduction is $32,200 for married couples filing jointly, $16,100 for single filers, and $24,150 for heads of household, so a lot of homeowners get no tax benefit from mortgage interest either way.[7] For those who do itemize, interest is deductible on the first $750,000 of mortgage debt.[8]

Smarter alternatives to extra mortgage payments

Paying down the mortgage isn't the only good use of spare cash, and depending on your situation, a few alternatives may do more for you.

Invest it

If your rate is on the lower end, putting the money into index funds or other long-horizon investments can outrun the interest you'd save, given enough time and risk tolerance. Returns aren't guaranteed the way mortgage savings are, so this fits people with a solid stomach for volatility and years to ride it out.

Shore up your emergency fund first

If you don't have three to six months of expenses set aside, that comes before any extra mortgage payment. It's the difference between weathering a job loss and borrowing against your house to get through it, and as the Fed's data shows, most households aren't there yet.[6]

Pay off high-interest debt

Credit card balances and personal loans usually carry rates well above any mortgage, so clearing them saves you more per dollar than prepaying ever could. Knock those out first, then circle back to the mortgage question with the freed-up cash flow.

The sinking-fund strategy: keep the money, keep the option

There's a middle path that too few homeowners consider. Instead of making irreversible extra payments, route the same money into a dedicated payoff fund, a separate account you feed on the same schedule you'd have used for prepayments. When it's large enough to wipe out the balance, you decide then whether to pull the trigger. In the meantime, the money is still yours.

Smith frames the trade-off better than a spreadsheet can. "Home equity has a rate of return of 0%. If I took $6,000 a year and put it into something that did have a return, even something with no risk and low yield, my money is still making money. If I ever change my mind, I can make that extra payment. But if I want my equity money back, I have to pay to get it. I want the debt and I want to leave the door open. But that door only swings one way."

This only works if you leave the money alone, which takes discipline. And you're swapping a guaranteed return for flexibility plus whatever market risk you take with the fund. If you know you'll raid the account, the guaranteed route may suit you better. If you value keeping your options open, this is a strong middle ground.

Recasting: the option most people don't know they have

If your real goal is a lower monthly payment, extra payments won't get you there, and this is where a lot of homeowners get stuck. A straight extra payment shortens your loan but leaves your monthly bill unchanged. A recast is different: you make a lump-sum payment toward principal, and your lender re-amortizes the loan over the same remaining term at the same rate, which lowers your monthly payment.

Smith ties it directly to the sinking-fund idea: "If I put $6,000 aside for five years and then I want to take that chunk of change and throw it at my mortgage, I'm going to recast the loan. There are only three figures in a mortgage calculation, the balance, rate, and term. If you can throw tens of thousands of dollars, you can recalculate with one of those three figures, and then you can actually lower your payment. Most of the loans we write, we make sure the client has the ability to recast one time." Save, then recast: you get the lower payment without giving up your rate.

A few specifics to check before you count on it. Recasting usually costs a one-time fee in the range of $150 to $500, far cheaper than the closing costs of a refinance. Not every loan qualifies, though. Government-backed loans (FHA, VA, and USDA) generally can't be recast, so this is mostly an option on conventional and jumbo loans. Ask your servicer whether your loan is eligible and what their minimum lump sum is before you plan around it.

When extra payments are the wrong move

For some homeowners, prepaying is the wrong call even after the emergency fund is full and the high-interest debt is gone. A few situations where the money belongs elsewhere:

Your rate is low

If you locked in something in the 3% to 4% range, the guaranteed savings from prepaying are hard to justify when safer options can match or beat that return.[5]

You might move or refinance soon

The guaranteed return only fully materializes if you keep the loan to the end. Prepaying also reduces the balance you could later refinance or borrow against. If a move or refinance is likely in the next few years, keeping the cash liquid usually wins. And with the 15-year fixed averaging 5.96% for the week of Aug. 13, 2026, refinancing into a shorter term is a live alternative for some homeowners who want to pay off faster.[1]

You need the money accessible

Once it's in your home, you can't get it back without selling or borrowing against your equity. If there's any chance you'll need it, keep it where you can reach it.

Your emergency fund is thin or you carry high-interest debt

Both come first. Prepaying while carrying a credit card balance costs you money, since that debt almost certainly costs more than your mortgage saves.
