What is this calculator for?
You're earning $98,000 in Austin and just got an offer for $135,000 in San Francisco. Sounds like a 38% raise — but you've heard housing in SF will eat the entire increase. The cost of living comparison tells you what your Austin salary actually buys in SF, what salary you'd need in SF to match your Austin purchasing power, and where the dollar differences come from category by category.
Cost of living differs dramatically across US metros, primarily driven by housing. SF, NYC, Boston, San Jose, Honolulu have housing costs 2-4x the US average; Cleveland, Detroit, Memphis, Birmingham, Buffalo are 30-50% below average. Non-housing costs (food, transportation, healthcare, taxes) vary too but with less spread — typically within ±20% of national average for major metros.
This calculator uses BLS Consumer Expenditure Survey data and regional cost indices (BEA Regional Price Parities, MIT Living Wage Calculator data) to estimate cost-of-living differences between US cities. Output: salary equivalence, monthly budget breakdown comparison, and the percentage premium or discount in your destination vs your origin.
How to use this calculator
Select your origin city (where you currently live) and destination city (where you're considering moving). The calculator handles major US metropolitan areas plus state-level averages for smaller cities.
Enter your current annual salary or monthly take-home pay. The calculator produces equivalent figures in the destination city — what salary you'd need to maintain the same purchasing power.
Optionally enter your current monthly budget breakdown: housing, food, transportation, healthcare, savings. The calculator scales each category by the destination city's specific multiplier for that category. Housing typically dominates the difference; food and consumer goods are more uniform.
For two-job comparison: enter both offers and both cities. The calculator shows which produces higher purchasing power after cost-of-living adjustment.
Understanding your results
The calculator returns equivalent salary in destination, monthly budget comparison across major categories, and the overall cost premium/discount percentage.
Sample comparison: Austin $98,000 → San Francisco. Overall cost-of-living index difference: SF is roughly 65-75% more expensive than Austin. Equivalent purchasing power salary in SF: $162,000-172,000. A $135,000 offer is approximately 20% LESS purchasing power than the Austin job despite the higher headline number.
Category breakdown (Austin → SF approximate multipliers):
Housing: 2.5-3.0x. Austin rent for 2BR ~$1,800; SF $4,500-5,500. The single biggest contributor to the gap. Home purchase: Austin median $475K; SF median $1.3M+.
Food: 1.1-1.2x. SF restaurant meals roughly 20% more expensive; groceries roughly 10% more.
Transportation: 1.05-1.15x. SF parking and gas more expensive; offset by transit options reducing car ownership cost.
Healthcare: 0.95-1.05x. Roughly similar across major metros.
Childcare: 1.5-2.0x. SF infant care $3,000+/month; Austin similar care ~$1,500-2,000.
Taxes: California state income tax 9.3-13.3% on professional salaries; Texas 0%. On $135K, CA tax adds $10,000-13,000/year vs TX.
State tax matters enormously. Cost-of-living indices typically don't fully capture state income tax differences. Moving from a no-tax state (TX, FL, NV) to a high-tax state (CA, NY, NJ) on a $200K salary loses you $14-22K to state tax — equivalent to a 7-10% pay cut. Always include state tax in cost-of-living comparisons; the official indices sometimes understate this.
The lifestyle equivalence question. "Equivalent purchasing power" assumes you'll consume the same lifestyle. But cities offer different lifestyle defaults — NYC and SF make sense at higher costs partly because public transit, walkability, and density let you live without a car (saving $7,000-12,000/year vs car-dependent metros). Austin and Atlanta optimize differently — bigger houses, more cars, suburban amenities. The "equivalent salary" calculation assumes apples-to-apples consumption; in reality, people adjust lifestyle to the city. Moving from Austin to SF on the "equivalent salary" might mean smaller apartment but lower car costs and more cultural amenities. The calculator's "you need $162K" is one anchor; lifestyle preferences can move the answer significantly.
A worked example
Maria, 32, currently earns $86,000 in Atlanta. She's considering offers in three other cities:
Offer 1: Charlotte, NC — $89,000. Charlotte cost of living vs Atlanta: roughly equivalent (5% higher on housing, similar elsewhere). $89K in Charlotte ≈ $86K in Atlanta. No real change in purchasing power.
Offer 2: New York City — $128,000. NYC cost of living vs Atlanta: roughly 90-100% higher. Equivalent purchasing power in NYC for her $86K Atlanta lifestyle: $163K-172K. Her $128K offer is about 25% LESS purchasing power. Plus NY state tax adds $7,500/year vs GA (Atlanta) — slightly compounding the gap.
Offer 3: Nashville, TN — $84,000. Nashville cost of living vs Atlanta: 10-15% higher on housing, mixed elsewhere. Equivalent purchasing power salary in Nashville: $93K-99K. Her $84K offer is about 12-15% LESS purchasing power. Plus TN has no state income tax (saves ~$4,500/year vs Atlanta GA — partially offsets the cost-of-living difference).
Combined analysis: Charlotte offer is roughly equivalent to current. NYC offer is a substantial pay CUT in purchasing power terms despite higher salary. Nashville offer is also a small pay cut despite the no-tax bonus.
Maria notes that the headline-salary analysis would have suggested NYC at $128K was a 49% raise. The reality is closer to a 20% pay cut. Whether NYC is worth that depends on non-financial factors — career opportunity, lifestyle preference, family proximity, professional network. The right framing isn't "I'm getting a raise to NYC" but "I'm taking a pay cut for the privilege of NYC's job market and lifestyle." That can be a reasonable trade or unreasonable depending on her priorities.
She ultimately picks Charlotte. The equivalent purchasing power, slightly better growth-trajectory job, and lower cost of living growth than Atlanta. Five years later her Charlotte salary has grown to $115K; she's bought a starter home, started building savings. In NYC at the same salary trajectory she'd have still been renting and accumulating less savings despite the higher gross income.
