Let's be honest: South Carolina isn't cheap. But within that premium market, there are cities where your dollar stretches meaningfully further. Charleston proves it with a cost index of 121 — we had to double-check this one — , the lowest in South Carolina, and we've ranked all 3 contenders to help you find the best deal in an expensive landscape.
Charleston comes in at #1. Rent is $2,127 a month. Household income is $90,038. The cost of living index is 121. That's about what we'd expect given the state context.
Value = income ÷ cost index. The national benchmark ratio is 718. Charleston delivers 744 — 4% more purchasing power per dollar earned. This metric catches cities that expensive-but-high-paying rankings miss: a $90K salary in a city with index 80 buys more than $120K in a city with index 150 (and that gap widens if you factor in state taxes).
What makes this tricky: The 3 cities we track in South Carolina paint a clearly affordable picture. And broadly, average cost index: 105. Median rent: $1,752/month — not a number you see very often, by the way — . Household income: $69,493. South Carolina is known for Lowcountry charm and migration-driven growth — and the data backs that reputation convincingly.
Bottom line: Charleston leads this ranking for clear, data-backed reasons — but the "best" city depends on your priorities.

Cost of living indices are normalized to 100 (national median) using Zillow rent as the primary signal, with sub-category adjustments derived from regional BLS price data. Rankings are updated monthly as new data is released.
