The difference between a comfortable retirement and a tight one often comes down to location. In South Carolina — known for Lowcountry charm and migration-driven growth, we evaluated 3 cities on healthcare costs, tax burden, and cost of living. Columbia is the top pick for 2026 (not adjusted for inflation, but still telling). One to watch.
Retirement affordability is about protecting fixed income. And from what we can tell, our model weights healthcare costs at 25 points (medical bills are the #1 financial risk in retirement), cost index at 25 points, and state tax burden at 15 points (taxes directly reduce pension and Social Security income). Columbia leads with low healthcare costs, a 6.4% state tax rate, and a cost index of 94. North Charleston offers competitive healthcare and cost metrics.
In plain English: Dive into Columbia's numbers: cost index 94 (18 points below national average), rent $1,459/month, income $55,653, and a home price of $226,769. The city's cost profile isn't flat — Housing is the cheapest category at 84, while Healthcare runs 96. With 129,330 residents, it balances mid-size city convenience with manageable costs (that's pre-tax, of course).
If you only look at rent, it's perfect. And as a general rule, zoom out and it's complicated. In Columbia, the healthcare index sits at 96 — not a dealbreaker, but worth knowing about (that's pre-tax, of course).
What to do with this data: use the ranking as a shortlist, then dig into the city profiles for trend lines and category breakdowns. And as far as the data shows, the difference between #1 and #5 is often smaller than the difference between "good on paper" and "actually fits my life." Compare your top picks with our calculator to see real take-home numbers. A real contender.
