The Real Cost of Living in Charleston, SC (2026)

Charleston has a reputation as an expensive coastal city, and you would expect the cost of living to match. The reality is more interesting. Overall, Charleston lands close to the national average, and depending on which measure you trust, it can come in a little below or a little above. The thing that swings the whole number is housing. Almost everything else is within striking distance of normal, and a couple of categories are actually cheaper than the national average. Let me break it down honestly, including the one tax advantage that quietly changes the math for anyone buying a primary home here.

Housing: the number that moves everything

Housing is the big variable, so let me give you real local data instead of a national aggregator’s guess. Based on MLS sales in mid-June 2026, the tri-county median sale price was around $465,000. But that single number hides a wide spread across the area:

• West Ashley, parts of James Island, and North Charleston offer more affordable entry points.
• Summerville and the Cane Bay/Nexton corridor in Berkeley County add a lot of new construction value at a range of price points.
• Mount Pleasant, Daniel Island, the peninsula, and the barrier islands carry a significant premium.

So whether Charleston feels expensive depends entirely on where you look. The same income that buys a modest condo closer to downtown might buy a four-bedroom new build twenty-five minutes out. On the rental side, the average apartment runs in the low-$2,000s per month, with downtown well above that and outlying areas below it. Rent has been roughly flat over the past year, which is a relief after the spikes a few years back.

Utilities: a touch higher, and here is why

Expect utilities to run slightly above the national average. The culprit is summer. Charleston’s heat and humidity mean your air conditioning works hard from late spring into early fall, and electricity bills reflect it, often landing north of $200 a month in peak season. The trade-off is mild winters that are easy on the heating bill. Budget for the summer AC and you will not be surprised.

Groceries and everyday costs: slightly above average

Groceries tend to run a few percent above the national average. Nothing dramatic, but the coastal location and tourism demand nudge prices up a little. The flip side is the payoff: the seafood is fantastic, and the farmers markets are genuinely good, which can tempt you into spending a bit more on food because you want to, not because you have to.

Healthcare: actually cheaper

Here is a pleasant surprise. Healthcare services in Charleston tend to run noticeably below the national average, with some routine services coming in well under typical costs. Combined with strong systems like MUSC and Roper St. Francis, the healthcare picture is a quiet point in Charleston’s favor, especially for retirees and families weighing a move.

Transportation: close to average

Transportation costs sit near the national average. Gas prices are typically reasonable for the region, and most of the metro is car-dependent, so factor in a vehicle and insurance. Public transit exists but is limited, so do not plan on it as your primary way around unless you are downtown.

The property tax advantage newcomers miss

This is the one that catches people off guard, in a good way. South Carolina assesses an owner-occupied primary residence at a 4 percent ratio, while second homes and investment properties are assessed at 6 percent. The practical effect is that the property tax bill on your primary home is meaningfully lower than what owners in many other states pay, and lower than what a second-home buyer pays on the identical house here. For a lot of relocating families, this single line item offsets a chunk of the higher housing cost. I broke down exactly how the 4 percent versus 6 percent assessment works in a separate post, and it is worth reading before you buy, because you have to actually apply for the 4 percent rate. It is not automatic.

So, is Charleston affordable?

Honest answer: it is more affordable than its reputation suggests, with one big asterisk called housing. If you are flexible on location and willing to look at the right area within the tri-county market, your money goes a long way. If your heart is set on the peninsula or the barrier islands, you will pay coastal premiums. The smart move for anyone relocating is to match your budget to the right area rather than assuming “Charleston” means one price. My full guide to moving to Charleston walks through the relocation side of that decision in more depth.
