Cost of Living in Montgomery County, MD: What You Need to Earn in 2026

If you're thinking about moving to Montgomery County, Maryland, one of the first questions you're probably asking yourself is: how much money do I actually need to live there? And I'm not talking about how much you need to just survive here. I'm talking about what it actually costs to have a normal life here.

What does housing cost? What are you going to spend on groceries? What does it cost to fill up your car? What about childcare, utilities, going out to dinner? And there's also a very new change here in Montgomery County that could mean that some homeowners are paying hundreds of dollars more this year than ever before. A lot of people still don't realize that it actually happened. And if you're buying a home in Montgomery County, it's something that you absolutely need to know.

Montgomery County is expensive. There's really no point in pretending otherwise. But there's also an enormous difference between living in Bethesda and living in Germantown, or buying a condo in Rockville or a detached home in Potomac. So instead of just throwing a bunch of numbers at you, I want to show you what living here actually costs as of fall 2026, and then we'll figure out what income you realistically need to live here.

Montgomery County: The Big Picture on Housing and Daily Expenses

Let's start with the big one: housing. As I'm recording this in the fall of 2026, the median sold price in Montgomery County is about $679,000. But honestly, this number doesn't tell you hardly anything. Because the county is enormous, and what $679,000 buys you depends entirely on where you're looking.

If you're renting, that's not exactly inexpensive either. The median rent across Montgomery County right now is around $2,900 a month. So housing is going to be the biggest variable when you're thinking about relocating to Montgomery County. When somebody contacts me and says, "Caryn, our budget is $800,000, can we live in Montgomery County?" I answer them: absolutely. But the big question is, where? What kind of house? Because $800,000 can look very different depending on whether we're looking in Bethesda, Rockville, Gaithersburg, or Germantown.

Then of course, if you are buying, we've got interest rates. As of today, Freddie Mac's average 30-year fixed mortgage rate is 6.76%. Your rate could obviously be higher or lower depending on your credit score, loan type, down payment, lender, and other factors. But let's just use this as an example. So if you bought a $650,000 house and you put 20% down, you're borrowing $520,000 at 6.76%. The principal and interest would be around $3,376 a month. That's before property taxes, before homeowner's insurance, before an HOA or a condo fee if that applies, and before anything breaks. So you're not just buying a $650,000 house and spending $3,376 a month to live. That is just the mortgage principal and the interest.

Now let's get into the stuff that you spend money on every week. Groceries. This is certainly one of those things that's difficult to give just one number because you can shop at Costco or Giant, or if you prefer to shop at Whole Foods, you'll end up spending considerably more. But MIT's 2026 living wage calculator has actual estimates specified for Montgomery County. For an adult, they estimate food at about $5,200 a year, which is roughly $433 a month. For two adults, it's about $9,500 or around $794 a month. And for two adults with two children, it's about $15,200 a year, and that's roughly $1,270 a month just for food.

And if you've been grocery shopping here lately, you will understand prices have definitely gone up. The Bureau of Labor Statistics reported that groceries in the Washington metro area, which includes Montgomery County, were up 5.6% year over year. So yes, groceries are very expensive here, and it just seems like they're only going up.

Now let's talk about something else that you're going to notice pretty quickly if you move here, gas. As I'm recording this, Montgomery County is generally running around $4.20 a gallon depending on where you fill up, and obviously individual stations can be higher or lower. And it's really kind of interesting here in Montgomery County because if you know, like some of us locals do, where the cheap gas is, it'll be on that $4 to $4.20. But if you don't know and you just go to any random gas station in Bethesda or Potomac or even closer into DC, it can be like a dollar more. So just be aware there are cheaper stations. Let me know if you want to know what they are. So if you're coming here from someplace where gas is lower, this is going to come as a very unpleasant surprise.

And depending on where you live in Montgomery County, you may drive a lot. If you're living in downtown Bethesda and you're taking the Metro to work every day, well, that's one thing. But if you're living out further in Potomac or North Potomac, Darnestown or Germantown, and you're driving everywhere, that's a completely different transportation budget. MIT estimates transportation costs for one person in Montgomery County at around $8,200 a year. For two adults with two children, it's $13,700 a year. Now that includes more than just gasoline. It's an estimate of overall transportation expense, but that's more than $1,100 for a family of four a month.

And then there are utilities. This is another category where I don't want to give you one just generic fake answer of what utilities are going to cost. Because it depends enormously on the house. A 2-bedroom condo in Rockville and a 5,000-square-foot home in Potomac are not remotely the same thing. A lot of homes here are older. Some are very energy efficient. Some are absolutely not. And our summers here are very hot and very humid. So you will be using air conditioning all summer. And our winters here get cold. So you will be using the heat. You may have electric heat, natural gas, or even oil.

So when you're looking at buying a house here, you will get the utility history for the past 12 months as part of the disclosures of that particular house. It will give you an idea of what it costs to power up that house. But it's really important for you to keep in mind that everybody does things differently. Everyone has different preferences for temperatures, for heat and air conditioning. So it gives you a general idea, but it's not perfect, but it's something.

And don't forget, your phones and your internet. MIT's estimate for internet and mobile service works out to around $133 a month for one adult and about $181 a month for a two-adult household. None of these things by themselves sound that bad, but this is where the cost of living creeps up. It's $180 here, $1,200 for groceries there, $4.20 or more a gallon for gas.

And then we get to the one that completely can change the equation for families with children, childcare. This number is kind of shocking. For two working adults with one child, MIT estimates childcare in Montgomery County at approximately $20,000 a year. That's roughly $1,670 a month. Two children, just over $40,000 a year. That's about $3,340 every single month.

And that's why I don't think you can answer the question, what salary do I actually need to live in Montgomery County, without knowing who's in the household. A couple that's making $150,000 a year with no children and no major debts could have a completely different lifestyle from a couple making $200,000 a year with two children and childcare. The second family makes $50,000 more, but they're potentially spending $40,000 a year in childcare. That's a huge difference, and we haven't even gone out to dinner yet.

Restaurants are another place where you are going to feel the cost of living here. I'm not going to tell you that dinner costs exactly X dollars because obviously you can get tacos or you can go to a high-end restaurant in Bethesda and spend hundreds of dollars, but the Bureau of Labor Statistics says restaurant food in the Washington area is also up compared to last year. And anecdotally, as somebody who lives here, this is one of those expenses that you do notice. Dinner for two, couple drinks, tax and tip, it adds up really quickly.

Bethesda: Metro Access Meets Million-Dollar Price Tags

Let's talk about Bethesda . The median sold price in Bethesda was around $1.33 million. If you're renting, the median rent is closer to $3,950 a month. So right away, you can see that Bethesda is significantly more expensive than the county average.

But here's what you get for that premium: Metro access. If you're living in downtown Bethesda and you're taking the Metro to work every day, that changes your transportation costs dramatically. You're not filling up your car as often. You're not sitting in traffic. You have walkability. You can walk to restaurants, shops, services. That lifestyle has real value, especially if you're commuting into DC.

The trade-off is obvious. You're paying a lot more for housing. And gas can be a dollar more per gallon at some stations in Bethesda compared to other parts of the county. If you tell me that you make $100,000 a year, have very little saved for a down payment, and you want a detached house in Bethesda, I'm going to be honest with you, that is really, really, really going to be very, very difficult.

But if you're a couple making $150,000 to $200,000 with no children, or you're coming here with substantial equity from selling another house, or you're willing to look at condos and townhouses, then Bethesda starts to make more sense. The Metro access alone can save you thousands of dollars a year in transportation costs, and the walkability means you're not driving everywhere for every errand.

Potomac: Acreage and Space Come at a Premium

Potomac is another high-end area in Montgomery County. The median sold price is about $1.29 million, so it's right there with Bethesda in terms of cost. But the lifestyle is completely different.

In Potomac, you're getting larger properties. You can find homes with acreage. You're not walking to the Metro. You're not walking to dinner. You are driving. And that means higher transportation costs, more time in the car, and yes, you're filling up at those gas stations that can be a dollar more per gallon if you're not careful.

So if you want space, if you want a yard, if you want privacy and a bigger home, Potomac offers that. But you're paying for it in two ways: the purchase price and the ongoing cost of driving everywhere. If you work from home or you don't mind the commute, that trade-off might be worth it. But if you're commuting into DC five days a week, you're going to feel that cost.

And just like Bethesda, if you're trying to buy a detached home in Potomac on a $100,000 household income with little saved for a down payment, that's going to be extremely difficult. You're looking at a very different price point here.

Rockville: More Affordable Options Without Leaving the County

Rockville is where things start to open up a bit more. The median sold price in Rockville was about $680,000, which is right around the county average. So you're getting significantly more affordability than Bethesda or Potomac, but you're still in Montgomery County with access to good amenities and reasonable commutes.

Rockville has condos and townhouses available as more affordable options. So if you're a household making $100,000 to $150,000 and you're willing to look at attached housing or smaller detached homes, Rockville gives you a lot more choices than the higher-end areas.

You're also not as far north as Germantown or Gaithersburg, so your commute into DC or Bethesda is still manageable. You're not driving an hour each way. And you still have access to shopping, restaurants, and services without feeling like you're out in the middle of nowhere.

So if you're relocating to Montgomery County and you want to balance affordability with location, Rockville is one of those places where you can make your budget stretch further without giving up too much convenience.

Germantown: Northern Affordability with a Commute Trade-Off

Germantown is in the northern part of Montgomery County, and it's one of the more affordable options in the county. You're going to find lower home prices here compared to Bethesda, Potomac, or even Rockville. But the trade-off is that you're going to be doing more driving.

If you work in DC or Bethesda, you're looking at a longer commute. If you need to run errands or go to appointments, you're driving. There's no Metro access up here. You're not walking to dinner. So your transportation costs are going to be higher, and you're spending more time in the car.

But if you're looking to get the most house for your money, and you work from home or you don't mind the commute, Germantown can give you a lot more space and a lot more house than you'd get closer in. It's just about knowing what you're trading off.

Gaithersburg: Another Budget-Friendly Alternative

Gaithersburg is another more affordable housing option in Montgomery County. Like Germantown, you're further north, so you're going to be driving more. But you're also getting more house for your money.

If you're a household making $100,000 to $150,000 and you want a detached home with a yard, Gaithersburg is one of the places where that becomes possible. You're not going to find that in Bethesda or Potomac at that price point. But you are going to be commuting if you work closer into DC or Bethesda.

So it's the same trade-off as Germantown: more house, lower cost, but more driving and more time on the road.

North Potomac: More Driving, Less Walkability

North Potomac is another area where you're going to be doing more driving. You're not in downtown Bethesda. You're not walking to the Metro. You're driving for commuting and errands.

But if you want more space and you're willing to drive, North Potomac offers that. It's just important to factor in those transportation costs when you're thinking about your overall budget. Because even if the house is more affordable than something in Bethesda, you're spending more on gas, more on car maintenance, and more time behind the wheel.

Darnestown: Space and Distance Go Hand in Hand

Darnestown is similar to North Potomac in that you're getting space, but you're also doing a lot more driving. If you're commuting into DC or Bethesda, that's a longer drive. If you need to run to the store or take the kids to activities, you're in the car.

So Darnestown works if you value space and privacy and you don't mind the commute. But it's not a walkable, Metro-accessible lifestyle. You're driving everywhere, and that's a cost you need to factor into your budget.

The $692 Tax Credit That Disappeared in 2026

Now there's one homeowner expense that I really want you guys to pay attention to because this changed in Montgomery County just this year. And this is the change that I mentioned at the beginning that a lot of people don't even really understand yet.

Montgomery County has something called the Income Tax Offset Credit, or ITOC. Eligible principal residences received a $692 credit every year. Beginning July 1st, 2026, that credit was reduced to zero. So if you received that credit last year, that's $692 that is no longer coming off your property tax bill. That's almost $58 a month.

And I want to be really clear about something because there's been some confusion about this. This is not the Maryland Homestead Tax Credit. That's something completely separate, and it still exists. What went away was Montgomery County's $692 income tax offset credit.

And $692 may not sound enormous when we're talking about million-dollar homes. But look at it this way. If your previous annual tax bill after the credit was around $6,000, losing that $692 just by itself is equivalent to an 11.5% increase over that $6,000. On a $10,000 bill, it's about 6.9%. And that's just the effect of losing this credit. Your assessments and other charges can change too.

And here's something that's also really important if you are planning on buying a house here. Do not look at the seller's current property tax bill and assume that's what you're going to pay. A longtime homeowner may have tax protections and credits that you just won't have as a new owner.

One of the disclosures that we do have as part of our seller disclosures when you buy a house is the estimated property tax for the full fiscal year of ownership. So you will get that as part of the seller disclosure package, but it's not always right. Because if you're buying new construction, they don't always know how big that new house is. So just be aware if you're buying new construction that you might want to have a new calculation. Don't just base it on what they give you.

What Different Income Levels Can Actually Buy You

Okay, so now that we've gone through all that, let's get back to the question: how much money do you really need to live in Montgomery County?

Here's where it gets interesting. MIT estimates that a single person with no children needs about $61,000 a year before taxes to cover what it considers basic needs in Montgomery County. Two working adults with no children need about $77,000 combined. But take those two working adults and give them two children, and suddenly MIT estimates that they need around $151,000 in household income before taxes just to cover those basic expenses. And with three children, it's over $191,000.

That's not my opinion, just to be clear. These numbers are from MIT's 2026 Montgomery County living wage calculator.

So let's make this really simple. If your household makes around $100,000 a year, can you afford to live in Montgomery County? Yes, absolutely. But your housing choices are going to matter a lot. Renting, buying a condo, looking at townhouses, going further north in the county, or having some substantial money for a down payment can completely change what $100,000 feels like. But if you tell me that you make $100,000 a year, have very little saved for a down payment, and you want a detached house in Bethesda or Potomac, I'm going to be honest with you, that is really, really, really going to be very, very difficult.

Now let's say your household makes around $150,000 to $200,000 a year. That's where considerably more options start to open up. But this is also where I want people to stop just looking at the income by itself. Do you have children and childcare? Do you have student loans, car payments? Are you saving aggressively for retirement? Do you travel? Are you paying college tuition? Did you sell another house and you're coming here with $400,000 worth of equity to put into the new house? All these things really matter. Two households making exactly $175,000 a year can have completely different lives here.

And once you're at $250,000 to $300,000, yes, you have significantly more choices, but I wouldn't automatically assume that means you can comfortably buy any house here. Just to keep with our numbers, a $1.5 million house with 20% down at that same 6.76% interest rate is around $7,800 a month in principal and interest alone. Then you add property taxes and homeowner's insurance and maintenance and all those other expenses we spoke about, and add two children and childcare, and you're potentially adding another $3,000 to $4,000 a month. Suddenly that $250,000 to $300,000 income doesn't quite sound as enormous as it did 30 seconds ago.

And that's really the point of this entire article. There just isn't one salary that makes Montgomery County affordable. It depends on what your life looks like. A couple making $150,000 with no kids, no debt, and a big down payment may be in a much stronger position than a family that makes $250,000 with two kids in childcare, student loans, and two car payments.

And then there's where you live. Bethesda versus Potomac. Potomac versus Rockville. Rockville versus Germantown. Maybe you want walkability and Metro and you're willing to live in a smaller house or a condo. Maybe you want an acre or two and couldn't care less about walking anywhere. Maybe you work from home. Maybe you're commuting downtown five days a week. Maybe your number one priority is getting the most house for your money. These choices can change your cost of living almost as much as your income does.

And the good thing about Montgomery County is you can find all of this here. You can find the two acres, you can find the smaller, older home. So if you're thinking about moving here, I wouldn't ask only, can I afford Montgomery County? What I would ask is, what kind of life can I afford in Montgomery County? Because that's a much better question. And sometimes moving 10 or 15 minutes in one direction completely changes that answer.
