That's a difference of ~$225/month, or ~$2,700/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%.
