Cost of Living Explained
Quick Answer
Cost of living is the amount of money needed to cover basic expenses like housing, food, taxes, healthcare, and transportation in a given area. It varies dramatically across the U.S. — a $75,000 salary in Des Moines provides a significantly better lifestyle than the same salary in San Francisco. When comparing job offers or planning a move, your take-home pay and local cost of living together determine your real purchasing power.
Cost of Living Index by Major City
The national average is 100. Higher numbers mean more expensive:
| City | COL Index | Housing Index |
|---|---|---|
| San Francisco, CA | 179 | 295 |
| New York City, NY | 172 | 278 |
| Boston, MA | 153 | 220 |
| Los Angeles, CA | 150 | 230 |
| Seattle, WA | 149 | 215 |
| Denver, CO | 129 | 160 |
| Austin, TX | 112 | 120 |
| Nashville, TN | 105 | 110 |
| Phoenix, AZ | 100 | 105 |
| Dallas, TX | 99 | 95 |
| Raleigh, NC | 96 | 90 |
| Indianapolis, IN | 89 | 75 |
| Memphis, TN | 82 | 62 |
The Biggest Factor: Housing
Housing typically accounts for the majority of cost-of-living differences. Compare average monthly rent for a 1-bedroom apartment:
| City | Avg 1BR Rent | Annual Rent Cost |
|---|---|---|
| San Francisco | $3,200 | $38,400 |
| NYC (Manhattan) | $3,500 | $42,000 |
| Los Angeles | $2,400 | $28,800 |
| Austin | $1,600 | $19,200 |
| Dallas | $1,400 | $16,800 |
| Raleigh | $1,300 | $15,600 |
| Indianapolis | $1,100 | $13,200 |
The rent difference between San Francisco and Indianapolis is $25,200/year. That is more than many people's entire annual tax bill. Check if you can afford rent at your salary.
Real Example: Salary Equivalence Across Cities
To maintain the same standard of living as $75,000 in Dallas, you would need:
| City | Equivalent Salary | Extra Needed |
|---|---|---|
| Dallas, TX | $75,000 (baseline) | — |
| Austin, TX | $84,900 | +$9,900 |
| Denver, CO | $97,500 | +$22,500 |
| Los Angeles, CA | $113,400 | +$38,400 |
| San Francisco, CA | $135,000 | +$60,000 |
| NYC | $129,600 | +$54,600 |
A $75,000 salary in Dallas has the same purchasing power as $135,000 in San Francisco. And that is before considering that California taxes reduce your take-home pay further than Texas (no state tax).
How Taxes Affect Cost of Living
State and local taxes are a major cost-of-living component that many indexes underweight:
| Location | $90,000 Take-Home | Annual State/Local Tax |
|---|---|---|
| Houston, TX | ~$70,600 | $0 |
| Tampa, FL | ~$70,600 | $0 |
| Denver, CO | ~$66,640 | ~$3,960 |
| Portland, OR | ~$63,000 | ~$7,600 |
| NYC | ~$59,600 | ~$11,000 |
A New Yorker earning $90,000 has $11,000 less per year to spend on the already-higher NYC prices. Use the relocation tool to compare tax-adjusted take-home pay across states.
How to Use Cost of Living in Career Decisions
- Evaluate job offers: A $120,000 offer in San Francisco may buy less than an $85,000 offer in Dallas. Use the SalaryHog calculator to compare take-home pay
- Negotiate salary: If relocating to a higher-cost area, ask for a salary adjustment that accounts for the difference
- Plan remote work: Working remotely from a low-cost, no-tax state while earning a high-cost-area salary is the best financial setup
- Budget realistically: Base your budget on net pay, not gross salary. Keep housing under 30% of take-home pay. Use the affordability tool
