A $100,000 salary delivers very different financial realities depending on where you cash it. In San Francisco, after taxes and a median one-bedroom apartment ($2,900/month), groceries, transportation, and basic expenses, most earners are left with marginal discretionary income and a savings rate in the single digits. The same $100,000 in Columbus, Ohio or Austin, Texas (once it was cheaper, now growing) can support a mortgage, meaningful retirement savings, and genuine financial slack. The cost of living isn't just a housing stat — it encompasses everything from a haircut to childcare, healthcare out-of-pocket costs, utility bills, and local taxes. This guide teaches you how to read cost-of-living indices, translate them into salary requirements, and use comparative data to make better relocation and remote work decisions in 2026.
What Cost of Living Indices Measure
The most widely used COL index is produced by the Council for Community and Economic Research (C2ER) and published as the ACCRA Cost of Living Index. It benchmarks six major spending categories across US cities relative to a national average of 100:
- Housing: ~30% weight (largest component)
- Grocery: ~13% weight
- Utilities: ~10% weight
- Transportation: ~10% weight
- Healthcare: ~5% weight
- Miscellaneous goods & services: ~32% weight
A COL index of 120 means that city is 20% more expensive than the national average overall. An index of 85 means it's 15% less expensive.
How to Calculate Your Required Salary in a New City
The core formula for equivalent purchasing power:
Required Salary = Current Salary × (Target City COL ÷ Current City COL)
You earn $90,000 in Austin, TX (COL index ~120). You're considering a move to Nashville, TN (COL index ~95).
Required Salary in Nashville = $90,000 × (95 ÷ 120) = $71,250
In other words, $71,250 in Nashville gives you the same purchasing power as $90,000 in Austin. If an employer offers you $85,000 in Nashville, you are genuinely ahead financially despite the lower nominal salary.

The Housing Multiplier Effect
Housing is not just the biggest COL component — it has a compounding financial effect. In high-cost cities:
- Higher rent means less saved for a down payment
- Higher home prices require larger down payments and mortgages
- Higher property taxes add to the total housing burden
- Higher housing costs leave less income for retirement contributions
Median home prices in 2026:
| Metro | Median Home Price | Monthly PITI (30yr @ 7%) | 25% Down Payment |
|---|---|---|---|
| San Jose, CA | $1,550,000 | ~$8,200 | $387,500 |
| Los Angeles, CA | $820,000 | ~$4,340 | $205,000 |
| Austin, TX | $490,000 | ~$2,590 | $122,500 |
| Columbus, OH | $295,000 | ~$1,560 | $73,750 |
| Memphis, TN | $195,000 | ~$1,030 | $48,750 |
The same 20% down payment budget of $100,000 barely touches a San Jose purchase but fully covers a Memphis home. Use the Mortgage Calculator to model monthly payments for any price range with your actual rate assumptions.
State Tax: The Hidden COL Multiplier
Cost of living comparisons that ignore state income tax are incomplete. California's high housing costs are compounded by a top income tax rate of 13.3%. Texas has zero state income tax but higher property taxes. The net effect:
- $120,000 salary in California (7.2% avg rate): Nets ~$88,000 after state tax
- $120,000 salary in Texas (0% state): Nets ~$95,500 after state tax
The $7,500 tax difference, combined with lower housing costs, means a $120,000 job in Dallas can feel significantly wealthier than the same salary in Sacramento. Use the Salary After Tax Calculator to compare net pay across states.
Remote Work and Geographic Arbitrage
One of the most significant wealth-building strategies available to remote workers in 2026 is geographic arbitrage: earning a high-cost-city salary while living in a low-cost area. If you earn $130,000 on a San Francisco salary scale while living in Columbus, Ohio:
- SF cost-adjusted equivalent: ~$130,000 ÷ 1.87 (SF COL index) × 1.0 (Columbus index) ≈ You need only $69,500 in Columbus to match SF purchasing power
- Surplus: $130,000 - $69,500 = $60,500 annual discretionary income advantage
- Tax advantage: No California income tax if domiciled in Ohio (4% flat vs. 13.3% top)
- Compounding benefit: Higher actual savings rate means dramatically more retirement wealth over 20 years
The Take Home Pay Calculator with Ohio's 4% rate vs. California's 9% shows meaningfully more take-home even on an identical gross salary.
Comparing Total Compensation, Not Just Salary
When comparing offers in different cities, build a Total Value of Compensation (TVC) model:
- Convert each offer to net take-home after state and local taxes
- Subtract estimated monthly housing cost (target 25–30% of net monthly)
- Subtract transportation (car payment, insurance, or public transit pass)
- Estimate remaining discretionary income in each scenario
- Factor in proximity to family, career trajectory, and quality of life (non-financial)
This approach converts the abstract salary number into a comparable financial reality that accounts for everything the recruiter doesn't mention.

Frequently Asked Questions
The most authoritative US source is the ACCRA Cost of Living Index published by C2ER. Numbeo, Expatistan, and BestPlaces also provide crowd-sourced cost data. For US metro comparisons, the Bureau of Economic Analysis Regional Price Parities (RPP) dataset provides official government estimates. Our Cost of Living Comparison Calculator uses a composite of major data sources for general estimates.
Only if your contract states so, or if your company has an explicit geographic pay policy. Many companies (especially large tech firms) now use location-based salary bands, so moving from San Francisco to Austin can result in a formal pay reduction. Before accepting a remote-work-and-relocate arrangement, get clarity in writing about how your comp will be affected.
This depends on your time horizon. If you plan to stay 5+ years, ownership builds equity in a market where that equity may be substantial. Short-term, the price-to-rent ratio in most high-COL cities (above 30:1) strongly favors renting mathematically. In low-COL cities with ratios below 15:1, buying is often immediately advantageous.
Remote work decouples income from location for millions of workers, enabling geographic arbitrage. The optimal strategy is earning at the compensation level of a high-cost market (where salaries are higher) while living in a mid or low COL area. The wealth-building impact over a 10-year career is often $500,000+ in additional savings capacity compared to living where you work in a high-cost city.
Absolutely. If you're accepting a role in a high-COL city, presenting data on the purchasing power differential versus your current location gives your request a factual basis. Conversely, if you're keeping a high salary while relocating to a low-COL area, be aware your employer may revisit compensation at review time with this same data.
