Where you live in America has a massive impact on your wallet. Our database tracks 300 major US cities across four regions, with cost indices ranging from 76 (Flint) to 244 (San Francisco) — a 168% spread between the cheapest and most expensive metros. Each city page below gives you detailed breakdowns across 38 cost categories, from roof replacements and HVAC installations to car insurance and professional salaries. The data comes from federal sources including the Bureau of Labor Statistics and U.S. Census Bureau, updated for 2026.
South (93 cities)
The South generally offers lower cost of living, driven by affordable housing and lower state taxes. Cities like Houston and San Antonio rank among the most budget-friendly metros in the country.
West (102 cities)
Western cities span the widest cost range in the US — from ultra-expensive San Francisco to relatively affordable Las Vegas. Climate, tech industry presence, and housing supply drive the variation.
Northeast (49 cities)
Northeastern cities tend to have higher costs due to dense populations, older housing stock, and strong job markets in finance, healthcare, and education. New York leads as the most expensive metro.
Midwest (56 cities)
The Midwest consistently ranks as the most affordable US region. Lower housing costs, moderate taxes, and a stable manufacturing-to-services economy keep everyday expenses well below the national average.
Frequently Asked Questions
What is a cost of living index?
A cost of living index measures how expensive it is to live in a particular city compared to the national average, which is set at 100. A city with an index of 120 is 20% more expensive than average, while a city at 85 is 15% cheaper. Our indices are calculated using BLS consumer price data, Census Bureau income statistics, and HUD fair market rents across 38 cost categories.
Which US city is the cheapest to live in?
Among the 300 major cities we track, Flint has the lowest cost of living index at 76, making it 24% below the national average. The most affordable cities tend to be in the South and Midwest regions, where housing costs and state taxes are typically lower.
Which US city is the most expensive?
San Francisco tops our list with a cost index of 244, meaning it's 144% above the national average. High-cost cities are typically driven by expensive housing markets, strong demand for professional services, and higher wages that push up the price of local services.
How often is the cost data updated?
Our cost data is sourced from federal databases including the Bureau of Labor Statistics (BLS), U.S. Census Bureau, Department of Housing and Urban Development (HUD), and the Energy Information Administration (EIA). These sources update quarterly to annually, and we reflect the latest available data in our calculations for 2026.
