Cost of Living in Charleston SC 2026: Top 10 Costs

What Is the Cost of Living in Charleston SC in 2026?

It depends on which county you live in, more than almost anything else. For two working parents with one child, MIT's Living Wage Calculator puts the basics at about $97,400 a year. Income tax and property taxes here run lower than most of the country. Homeowners insurance runs more than double the national average. And the same household buying a median-priced home can spend more than $1,500 a month more in Charleston County than in Berkeley County. If you're thinking about moving to Charleston in the next year, that county decision matters more than your salary.

I'm Brett Kelley, team leader of The TREAT Team at SCSOLD, LLC. I've been licensed in South Carolina since 2016, and my family and I live in Hanahan, so these costs aren't theory for me. Below are the top 10 costs people ask me about before they move here, each one scored against the national average. If you'd rather watch, the full video is right here.

First, Charleston Is Really Three Counties

When people say "Charleston," they usually mean the whole metro. That's actually three counties: Charleston County, Berkeley County, and Dorchester County. Home prices, property tax rates, and insurance quotes all shift depending on which one you land in. Keep that in mind for every number below.

The Scorecard: Charleston vs. the National Average

Final score: Charleston 4, national average 3, split decisions 3. Figures as of late September 2026. Full sources are listed at the end of this post. These are benchmarks, not quotes for your situation, and every number here can move.

Numbers 10 to 6: Taxes, Heat, Kids, Rent, and Property Tax

10. South Carolina income tax in 2026 (split decision)

For tax year 2026, South Carolina taxes the first $30,000 of taxable income at 1.99%. Income above that is taxed at 5.21%, down from a 6% top rate in 2025. On about $90,000 of taxable income, the effective rate works out to roughly 4%. If you're coming from California, New York, or New Jersey, that feels like a raise. If you're coming from Florida, Texas, or Tennessee, it's a brand new bill. So it depends on where you're moving from.

9. How hot is Charleston in the summer? (national average wins)

It's hot. The normal July high is about 91 degrees, and a typical year brings about 64 days at 90 or above. This past July we had 28 of those days in a single month, and it hit 100 on July 9. Add afternoon storms: June through August averages close to 20 inches of rain. Blue skies at 2:00, downpours at 3:00. The trade-off is winter. Most January days, you're at the park in a light jacket.

8. Things to do with kids when it's raining or 100 degrees (Charleston wins)

There's more to do than people expect. Locals get outside before 10:00 a.m. and head indoors or into the water in the afternoon. On rainy days, the Children's Museum downtown runs about $15 at the door, and there's the South Carolina Aquarium and 18 Charleston County Public Library locations. Our son's branch has a Thursday morning story time. He doesn't love sitting still, but it gets everybody out of the heat. Charleston County Parks runs three water parks, and there are free splash pads at places like Doty Park in Summerville and Central Creek Park in Goose Creek. Day camps nationally run about $365 to $435 a week. Here, the Cane Bay YMCA camp is about $200 a week for members, and most specialty camps run $300 to $400.

7. Average rent in Charleston SC (national average wins)

Median rent here is $1,709 a month, compared to $1,390 nationally, according to Apartment List's August and September 2026 reports. Direction matters too. National rents are down 0.8% from last year, while Charleston rents are up 2.6%, and up 6.5% since January. Renting first while you learn the area is still a smart move for a lot of people. It just isn't cheap. If you're on the fence, our Charleston rent vs. buy calculator puts your own numbers side by side.

6. Charleston property taxes and the 4% rule (Charleston wins)

On a primary home, the effective property tax rate is about 0.32% in Charleston County, 0.42% in Berkeley County, and 0.54% in Dorchester County. Nationally it's about 0.9%. The average American property tax bill last year was $4,427, according to ATTOM. Using each county's effective rate and its August 2026 MLS median, we estimate the bill at about $2,118 in Charleston County, $1,722 in Berkeley County, and $2,079 in Dorchester County. Dorchester and Charleston County land at almost the same bill on homes $277,000 apart. Actual bills vary by tax district.

The reason is how South Carolina assesses property. A primary residence is assessed at 4% of its value. A second home or rental is assessed at 6%. The 4% rate is not automatic. You have to apply for it with the county where you buy, and missing that step can cost you real money every year.

Halftime score: Charleston 2, national average 2, split 1.

Numbers 5 to 1: Where the Real Money Is

5. How much is daycare in Charleston? (Charleston wins, but the waitlist is the catch)

Center-based infant care in South Carolina averages $10,474 a year, compared to about $15,000 nationally, according to Child Care Aware of America. That's roughly $375 a month less. Charleston-area centers can run above the state average, so tour a few. Watch how the staff interact with the kids, ask about meals, and ask about ratios.

Price isn't the hard part. Finding a spot is. The Post and Courier reported in December 2024 that South Carolina daycare waitlists can stretch a year, with some centers licensed for 135 children but staffed for about 100. Here's what I tell every client with a little one: get on two or three waitlists near where you'll actually live and work the day you go under contract, or sooner.

4. How much is homeowners insurance in Charleston? (national average wins, easily)

NerdWallet's 2026 data puts Charleston at about $5,720 a year for $400,000 of dwelling coverage. The national average is $2,490, so that's about 2.3 times higher. And it doesn't include flood insurance, which is a separate policy. This is the cost almost nobody budgets for.

Get insurance quotes during your due diligence period, not after closing. Ask for the flood elevation certificate on any home you're serious about. Inland parts of Berkeley and Dorchester County often quote lower than the coast. I'm not an insurance agent, so talk to one early. We can connect you with a resource who pulls several quotes at once. For the flood side, my guide to Charleston flood zones is a good place to start.

3. What is the average home price in Charleston SC? (split decision)

It depends on the county. In August 2026, the median home sold for about $662,000 in Charleston County, about $410,000 in Berkeley County, and about $385,000 in Dorchester County. The national median was about $429,000. Charleston County runs about 54% above the national figure. Berkeley and Dorchester both come in below it. Same metro, nearly a $280,000 gap.

2. What is the actual mortgage payment on a Charleston home? (split decision)

TREAT calculation. Assumes 20% down and a 30-year fixed rate of 7.03%, Freddie Mac's weekly average for September 24, 2026. That average rose to 7.28% on October 1, 2026, so today's payments run a little higher. Principal and interest only. Your real rate depends on your credit, down payment, and loan type, so treat these as benchmarks. Putting less than 20% down is fine, just add mortgage insurance. If the neighborhood has a pool and amenities, add HOA dues, and ask for them before you fall in love with the pool, the trails, and the docks.

1. How much do you need to make to live in Charleston? (Charleston wins, if you pick the right county)

This is the most searched question about living here. MIT's Living Wage Calculator says two working parents with one child in the Charleston area need about $97,000 a year before taxes to cover the basics. With two children, it's about $118,000. The median household in the Charleston metro earns $90,307, about 11% more than the national median of $81,604, according to the Census Bureau's 2024 American Community Survey. Paychecks are higher here. So is the bar.

But here's the real answer. It depends more on which county you buy in than on your salary. Take a household with one baby in daycare, buying a median-priced home with 20% down at 7.03%, and add property tax, insurance, car insurance, and electric:

TREAT estimates. *Inland counties use South Carolina's statewide insurance average. Excludes food, gas, health insurance, and HOA dues. Sources: NAR, Flex MLS, Freddie Mac, NerdWallet, SmartAsset, ATTOM, Child Care Aware, MoneyGeek, and EIA.

Buying in Charleston County runs about $926 a month more than the national figure. Buying in Berkeley County runs about $662 less, and Dorchester County about $766 less. That puts Charleston and Berkeley County $1,588 a month apart. The everyday stuff helps too: gas runs about 43 cents a gallon cheaper here (AAA, September 2026), and car insurance runs about $70 a month less (MoneyGeek, 2026).

Same metro. Same beach on a Saturday. More than $1,500 a month apart.

The people who struggle here usually picked the house first and ran the budget second. Flip it. Pick the area that fits your monthly number, then find the house. If you want to see how different areas compare, start with our Berkeley County guide and area pages like Hanahan, Goose Creek, and Summerville.

Bonus: Is a 2-1 Buydown Worth It Right Now?

For most buyers today, probably not. A 2-1 buydown lowers your rate 2% in year one and 1% in year two. In year three, your payment jumps to the full rate. It's a temporary discount. On a $400,000 loan at 7.03%, a 2-1 buydown saves about $515 a month in year one and $263 in year two, then nothing, and it costs roughly $9,300 to set up. The whole bet is that rates drop enough for you to refinance before year three. A lot of people who used one in 2022 and 2023 made that bet. Rates didn't drop, and now they're paying the payment they were trying to avoid.

The forecast doesn't show much relief. The Mortgage Bankers Association's September 2026 forecast holds 30-year rates at about 6.7 to 6.8% through 2027. And the 10-year Treasury, which mortgage rates follow, hit its highest level since 2007 in late September.

What we do instead: a permanent buydown with a seller credit

When the market gives buyers leverage, and right now it does, we negotiate a seller credit. Say $15,000 to $20,000. Then we use it to buy down the rate permanently. Each discount point costs about 1% of the loan amount. On a typical loan here, our lender estimates that can lower the payment by around $300 to $350 a month. Not for two years. For the life of the loan.

If you're selling, this part is for you. That same $20,000 as a price cut only lowers a buyer's payment by about $107 a month (20% down, 7.03%). As a credit toward points, our lender estimates $300 to $350 a month, about three times the impact. That's how sellers bring in more buyers and more offers without giving away more money. If you're getting ready to list, our seller strategy page shows how we price and position a home from day one.

These are illustrative examples, not a commitment to lend. Rates, points, and seller credit limits vary by loan program and borrower, so run your own numbers with a licensed loan officer before you decide. That's the difference between hoping rates drop and negotiating a payment you can count on.

Frequently Asked Questions

How much do you need to make to live in Charleston SC?

MIT's Living Wage Calculator puts the basic cost of living for two working parents with one child in the Charleston area at about $97,000 a year before taxes, and about $118,000 with two children. The bigger factor is which county you buy in. A household buying a median-priced home in Charleston County can spend more than $1,500 a month more than the same household buying in Berkeley County.

What is the South Carolina income tax rate for 2026?

For tax year 2026, South Carolina taxes the first $30,000 of taxable income at 1.99% and income above $30,000 at 5.21%, under H.4216. On about $90,000 of taxable income, that works out to an effective rate of roughly 4%.

How much are property taxes in Charleston SC?

Property taxes on a primary home are low compared to the national average because South Carolina assesses an owner-occupied primary residence at 4% of value instead of 6%. Effective rates run about 0.32% in Charleston County, 0.42% in Berkeley County, and 0.54% in Dorchester County, compared to about 0.9% nationally. The 4% rate is not automatic. You have to apply for it with the county where you buy.

How much is homeowners insurance in Charleston SC?

Plan on about $5,720 a year for $400,000 of dwelling coverage, about 2.3 times the national average of $2,490, and that does not include flood insurance, which is a separate policy. Inland parts of Berkeley and Dorchester County often quote lower than the coast. Get quotes during your due diligence period, before closing.

Is a 2-1 buydown worth it in 2026?

For most buyers right now, probably not. A 2-1 buydown lowers your rate 2% in year one and 1% in year two, then the payment rises to the full rate in year three. It only pays off if rates drop enough to refinance. With the MBA forecasting rates near 6.8% into 2027 and the 10-year Treasury at its highest level since 2007, a seller credit used for a permanent rate buydown is often the stronger move.

What is the median home price in Charleston SC by county?

In August 2026, the median sold price was about $662,000 in Charleston County, about $410,000 in Berkeley County, and about $385,000 in Dorchester County, compared to a national median of about $429,000. Same metro, but a gap of nearly $280,000 between Charleston and Dorchester County.

Charleston isn't one price. It's three counties with very different monthly numbers. Taxes are friendly, insurance isn't, and the county you choose can swing your budget by more than $1,500 a month. Pick the monthly number first, then the house.
