How does Columbia's cost of living compare to the national average?

Columbia’s cost‑of‑living index is 130, meaning expenses are about 30 % higher than the U.S. average (which is set at 100). This higher index reflects higher housing costs, transportation, and everyday goods. Your salary of $70,370 per year is also above the national median, which helps offset the increased expenses. When budgeting, factor in the higher rent, slightly higher grocery and service prices, and the cost of commuting if you travel outside the city.
