Cost of Living by City: How Location Affects Your Real Salary

A $150,000 salary in San Francisco is not the same as a $150,000 salary in Austin. Yet many people fixate on the salary number while ignoring the purchasing power that matters in real life. This guide helps you understand cost of living, evaluate salary offers across cities, and make informed decisions about where to live based on your financial goals.

Understanding Purchasing Power

Purchasing power is what your money actually buys. If housing costs are 50% lower in one city, you have more purchasing power despite the same nominal salary.

Cost of Living Index

A cost of living index compares prices across cities using a baseline (100 = national average). A city with an index of 120 is 20% more expensive than the national average.

Real Salary = Nominal Salary × (1 / Cost of Living Index)

This formula translates salary into purchasing power. A $150K salary in a city with index 120 has the same purchasing power as $125K in a city with index 100.

Major Cost Components: Where the Money Goes

Housing (The Largest Expense)

Housing typically accounts for 25–40% of living expenses. In expensive cities, it can exceed 50% of income.

Example: A one-bedroom apartment in San Francisco averages $2,800/month. The same apartment in Austin averages $1,400/month. Over a year, that's a $16,800 difference in housing alone.

Income Taxes

State and local income taxes vary dramatically. California charges up to 13.3% state income tax. Texas has no state income tax.

Example: A $150K salary in California yields approximately $104.5K after state and federal taxes. The same $150K in Texas yields approximately $112K—a $7,500 annual advantage just from taxes.

Transportation

Some cities are car-centric (Los Angeles, Austin, Denver) where you need a vehicle. Others are transit-friendly (New York, Boston, San Francisco). Car ownership costs $800–$1,200+ monthly.

Groceries and Dining

Grocery costs vary by region. Midwest cities tend to be cheaper; coastal cities more expensive.

Income Tax Differences by State

• •No state income tax: Texas, Florida, Nevada, Tennessee, Wyoming, South Dakota, Washington
• •Low state income tax (2–5%): Colorado, Utah, Arizona
• •High state income tax (8–13%): California, New York, New Jersey

Over a 30-year career, moving from California to Texas could save approximately $450K+ in state taxes.

Comparing Major Cities

San Francisco: The Expensive Outlier

San Francisco has one of the highest costs of living in the US (index ~180–200). Housing dominates: median one-bedroom ~$2,800/month. State income tax is 9.3%. After taxes and reasonable living expenses, a $150K salary provides roughly $60–70K annual discretionary income.

New York: Expensive but More Affordable than SF

New York (Manhattan) has a cost of living index around 140–160. Housing is expensive (~$2,500/month for one-bedroom). You might have $75–85K discretionary income annually.

Austin: Rapidly Rising but Still Affordable

Austin has a cost of living index around 110–120. No state income tax in Texas is huge. With modest living expenses, you could have $85–95K discretionary income annually.

Chicago: Affordable Big City

Chicago has a cost of living index around 100–110. Housing is reasonable: one-bedroom ~$1,200/month. After taxes and living expenses, you could have $90–100K discretionary income annually.

Comparing Salary Offers Across Cities

Step 1: Gather Cost Data

Find cost of living comparisons for each city. Focus on housing, taxes, and transportation.

Step 2: Calculate After-Tax Income

Calculate taxes for each location. Include federal tax, state income tax, and local taxes if applicable.

Step 3: Estimate Annual Expenses

Estimate major expenses: housing, transportation, groceries, utilities.

Step 4: Calculate Discretionary Income

Discretionary income = After-tax income − Essential expenses. Compare discretionary income, not nominal salary.

Real Example: Comparing Three Offers

• •San Francisco: $200K salary → ~$82,400 discretionary income after housing ($2,800/mo) and taxes
• •Austin: $160K salary → ~$92,000 discretionary income after housing ($1,500/mo) and no state tax
• •Chicago: $155K salary → ~$91,600 discretionary income after housing ($1,200/mo) and modest state tax

Despite the highest nominal salary, San Francisco offers the least discretionary income.

Remote Work and Geographic Arbitrage

Remote work has created opportunities for geographic arbitrage: working for a high-paying company while living in a low cost-of-living area.

When Remote Arbitrage Works:

• •Your employer doesn't adjust salary based on location
• •You move to a significantly lower cost-of-living area
• •There's no time zone disconnect affecting your work

When It Doesn't Work:

• •Employer adjusts salary based on location
• •Quality of life or career development suffers

Long-Term Wealth Impact

Location decisions compound over a career:

• •In San Francisco: Saves $60K/year → $5.3M net worth after 30 years at 6% returns
• •In Austin: Saves $80K/year → $7.1M net worth after 30 years at 6% returns

That $20K annual savings difference creates $1.8M in additional wealth over 30 years.
