Nobody expects rock-bottom prices in South Carolina — but that doesn't mean all cities are equally expensive. Standard stuff, really. Columbia (index 94, rent $1,459/mo) carves out real savings within a high-cost market. We analyzed 3 cities to find where your money goes furthest in 2026.
A closer look at Columbia: the cost index of 94 breaks down to a Housing index of 84 (strongest category) and a Healthcare index of 96 (weakest). Median rent is $1,459/month — 23% below the national median — while household income sits at $55,653, meaning locals spend about 31% of income on rent. That exceeds the recommended 30% threshold — affordability here depends on earning above the median.
And here's the trade-off: Here's the state-level backdrop: South Carolina averages a 105 cost index, $1,752/mo rent, and $69,493 income across 3 cities. That's $143 less than the national rent average. Lowcountry charm and migration-driven growth — and that context shapes every city in this ranking.
