That's a difference of ~$5/month, or ~$60/year. Actual costs vary based on your Medicare plan, supplements, and health needs.
Can I afford to retire in Columbia on a $50,000 annual income?
On a $50,000/year ($4,167/month) retirement income in Columbia, rent alone would consume approximately 30% of your budget (1BR rent ~$1,250/mo) and healthcare another ~10%. That leaves roughly 60% (~$2,500/mo) for groceries, transportation, and other expenses. This is tight — a studio apartment or lower-cost neighborhood would help.
