Cost of Living Comparison Calculator: Is It Worth Moving?

A job offer with a $30,000 raise sounds like a clear win. If the new city costs $40,000 more per year to live in after housing and taxes, you took a $10,000 pay cut.

Cost of living comparisons require looking at more than just the salary number.

The Five Variables That Actually Matter

1. Housing costs. The single biggest driver of cost of living differences. A 3-bedroom house in Dallas costs $350,000. The same house in San Jose costs $1.4 million. Rent differences are similar.

2. State income taxes. Nine states have no income tax: Florida, Texas, Washington, Nevada, South Dakota, Wyoming, Alaska, Tennessee, New Hampshire. Moving from California (13.3% top rate) to Texas (0%) on a $150,000 income saves $19,950 per year.

3. Local income taxes. New York City charges 3.88% on top of state tax. Philadelphia 3.75%. These are significant on six-figure incomes.

4. Property taxes. Texas has no state income tax but high property taxes (1.7-2.5%). Illinois has some of the highest property taxes in the country (2.07% average). New Jersey: 2.23%.

5. Everyday costs. Groceries, gas, utilities, childcare, and healthcare vary by 10-30% between regions but rarely dominate the calculation the way housing does.

A Real Comparison

Moving from San Francisco to Austin:

| Cost Category | San Francisco | Austin | Difference | |--------------|--------------|--------|------------| | Monthly rent (2BR) | $3,800 | $1,900 | -$1,900 | | State income tax on $150k | $15,500/yr | $0 | -$15,500 | | Groceries | $800/mo | $600/mo | -$200/mo | | Gas | $250/mo | $180/mo | -$70/mo | | Annual difference | | | -$46,000 |

A $150,000 salary in San Francisco has equivalent purchasing power to roughly $104,000 in Austin. If a San Francisco employer offers $160,000 and an Austin employer offers $130,000, the Austin offer is actually worth more.

The Homeownership Multiplier

The comparison changes dramatically if you are buying. A $300,000 mortgage in Austin versus $1,000,000 in San Francisco represents a $700,000 difference in borrowing.

At 7% mortgage rate:

• Austin: $1,996/month
• San Francisco: $6,653/month

That $4,657/month difference compounds into enormous wealth over 30 years, not just savings.

What Remote Work Changed

Remote work let many workers arbitrage location. A software engineer earning San Francisco market wages while living in Austin or Nashville captures the salary minus the cost of living. This is one of the few situations where geography truly multiplies take-home pay without a career penalty.

If your employer allows remote work and you are in a high-cost city, the financial case for moving is among the strongest moves available in personal finance.

Retirement and Social Security Taxation

State income taxes on Social Security benefits and retirement distributions affect retirees. States that do not tax Social Security include Florida, Texas, and many others. Illinois does not tax retirement income. Moving in retirement to a state with favorable retiree tax treatment is a legitimate tax planning strategy.

Frequently Asked Questions

What is the most reliable cost of living index?

The Bureau of Economic Analysis Regional Price Parities (RPP) provides comprehensive state-level data. For city-level comparisons, NerdWallet, MIT's Living Wage Calculator, and Council for Community and Economic Research C2ER data are commonly used. No single index captures everything perfectly, but they align closely on the large-scale differences.

How do I account for career trajectory in a move?

Salary growth potential matters as much as the starting number. Moving to a smaller market may offer lower cost of living but also lower salary ceilings and fewer job options. If your field is concentrated in a few cities (finance in NYC, tech in SF/Seattle), the salary premium of those cities often compensates for higher costs over a full career.

Does moving affect my federal taxes?

Federal taxes are based on income, not location. However, state and local tax deductions (capped at $10,000) and property tax deductions affect itemized deductions. High-cost-of-living states often have higher property taxes and income taxes, which previously had a partial federal offset. The $10,000 SALT cap limits this benefit significantly for high earners.
