The gap between the most and least expensive U.S. metros is now over 90%. The same lifestyle — same house size, same car, same groceries, same activities — costs nearly twice as much in Manhattan or San Jose as in Cleveland or Memphis. But not every category scales the same way.
Housing scales the most. Rent in the top-5 most-expensive metros runs $3,000–$4,500 for a two-bedroom; in the bottom-5 metros, $900–$1,200 gets you the same thing. Home prices swing even wider — a $1.4M house in the Bay Area is a $220K house in Oklahoma City.
Taxes scale a lot, in an underappreciated way. Nine states have no income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming). California's top rate is 13.3%. On $100,000 of income, that's a $5,000–$8,000/year swing before the mortgage even starts. Property tax rates range from under 0.5% in Hawaii to over 2.0% in New Jersey and Illinois — another $6,000+/year swing on a $400K home.
Groceries scale modestly. USDA data shows food-at-home costs vary about 15–25% between the cheapest and most expensive regions. Milk, eggs, and produce cost more in the Northeast and West; less in the Midwest and South. But the swing is measured in dollars per week, not per day.
Utilities depend on climate more than metro. Cooling a home in Phoenix or Houston runs $200–$400/month in summer; the same house in Portland or Minneapolis needs almost no cooling. Add winter heating and total annual utility spend can swing $2,000+ between similar-sized homes in different climates.
Auto insurance is heavily state-regulated. Florida, Louisiana, Michigan, and Nevada have the highest average premiums (often $2,500+/year). Vermont, Maine, and Idaho are among the lowest (often under $1,000). The difference is state minimums, no-fault laws, and litigation environments.
Childcare varies more than any category. Full-time infant care runs $2,000–$2,600/month in high-cost cities and $900–$1,300/month in lower-cost ones. For families with young kids, this is often a bigger regional swing than housing itself.
The 'globally priced' categories don't move. Netflix costs the same in Kansas and California. So do most subscription services, phones, internet plans, cars, and airline tickets. National-brand groceries also move less than most people expect.
The take-home. When comparing a job offer or a move, model the specific categories that scale — housing, state income tax, property tax, auto insurance, childcare, and utilities based on climate — and don't sweat the ones that don't (subscriptions, phones, national retail).
A cost-of-living calculator (BestPlaces, NerdWallet, Numbeo) gets you 70% of the way in ten minutes. Then adjust for your specific situation: kids in daycare, home size, HVAC-heavy climate, and any state-specific quirks.
Local labor markets matter. A cheaper city is cheaper for a reason — often because wages are also lower. Compare your specific role, level, and industry on Levels.fyi or Glassdoor for the destination before assuming the cost difference is pure savings.
Transportation is the biggest hidden variable. A city where you can live one-car (or car-free) saves $8,000–$14,000/year over a two-car metro. Most cost-of-living calculators don't weight this correctly — factor it in before comparing.
