Looking to relocate between two popular Mountain West cities? Understanding the cost of living differences between Boise, Idaho and Salt Lake City, Utah can help you make an informed decision. While both cities offer vibrant communities and outdoor recreation, their expenses vary significantly across housing, taxes, and daily living costs.
Overall Cost of Living Index
As of 2026, Boise is approximately 7% more affordable than Salt Lake City overall. To maintain the same standard of living that costs $7,500 monthly in Salt Lake City, you would need about $6,945 in Boise. This gap widens considerably when examining specific categories like housing and utilities.
Salt Lake City employers typically offer 5.2% higher salaries compared to Boise companies, which can offset some cost-of-living differences for workers relocating with comparable positions.
