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 — though some people might weigh that differently — , the lowest in South Carolina, and we've ranked all 3 contenders to help you find the best deal in an expensive landscape (that's pre-tax, of course).
A closer look at Charleston: the cost index of 121 breaks down to a Utilities index of 111 (strongest category) and a Housing index of 152 (weakest). And depending on your situation, median rent is $2,127/month — 12% above the national median — while household income sits at $90,038, meaning locals spend about 28% of income on rent. That's within the recommended 30% threshold, though it doesn't leave much room.
That's the upside. Fairly typical for a city this size. Here's the tension: Across South Carolina, the average cost of living index is 105 — 7 points below the national median. Known for Lowcountry charm and migration-driven growth, the state offers 3 tracked cities with median rents averaging $1,752/month. That's $143 less than the national average of $1,895. For dual-income households, this multiplies into serious savings (not adjusted for inflation, but still telling).
