High-cost-of-living (HCOL) areas are US regions where prices run well above the national average, concentrated in coastal California, the New York metro, Honolulu, Boston, Seattle, and Washington DC. The federal yardstick is the Bureau of Economic Analysis Regional Price Parity, where 100 equals the national price level. For FIRE, geography can swing your target number by seven figures.
Key takeaways
- The BEA Regional Price Parity (RPP) is the standard, government-backed cost-of-living index. National average = 100. Anything meaningfully above 100 is HCOL, anything below is LCOL or MCOL.
- In 2024, the priciest states were California (110.7), Hawaii (110.0), and New Jersey (108.8); the District of Columbia sat at 109.9. The cheapest were Arkansas (86.9), Mississippi (87.0), Iowa (87.8), and Oklahoma (87.8). Source: BEA, released February 19, 2026.
- The gap is wider at the metro level. In San Francisco, $100 buys about $84.58 of goods and services; in the cheapest metros it stretches past $120. Source: Tax Foundation analysis of BEA 2023 RPP.
- Replicating a $200,000 national-average lifestyle costs roughly $221,000 in California and about $174,000 in Arkansas. At a 4% withdrawal rate, that is a difference of nearly $1.2M in the portfolio you need.
- The cost gap is driven mostly by housing rents. Nine states levy no tax on wage income, and several are LCOL, which stacks two tailwinds for FIRE geoarbitrage.
What the HCOL map actually measures
Most "cost of living" maps online pull from crowdsourced sites with no methodology you can audit. The credible source is the Bureau of Economic Analysis Regional Price Parity, or RPP. It compares price levels across every state and metro area against the national average, which is fixed at 100.
Read it as a percentage. A state at 110 is about 10% more expensive than the national average. A state at 87 is about 13% cheaper. BEA publishes RPPs for all items plus a separate housing-rents component, and housing is where the spread gets extreme.
The RPP is the cleanest single number for the HCOL-versus-LCOL question because it is consistent, updated annually, and built from the same federal price data nationwide. The most recent release covers 2024 and came out February 19, 2026.
The most expensive and cheapest states
Here are the endpoints of the 2024 map. RPP of 100 is the national baseline.
| State | 2024 RPP | Read as |
|---|---|---|
| California | 110.7 | ~11% above average (highest state) |
| Hawaii | 110.0 | ~10% above average |
| District of Columbia | 109.9 | ~10% above average |
| New Jersey | 108.8 | ~9% above average |
| Massachusetts, New York, Washington | ~106 to 108 | HCOL band |
| National average | 100.0 | Baseline |
| Oklahoma | 87.8 | ~12% below average |
| Iowa | 87.8 | ~12% below average |
| Mississippi | 87.0 | ~13% below average |
| Arkansas | 86.9 | ~13% below average (lowest state) |
Source: BEA, "Real Personal Consumption Expenditures by State and Real Personal Income by State and Metro Area, 2024," released February 19, 2026. Values for Massachusetts, New York, and Washington are approximate and sit just inside the HCOL band.
Metro areas are where HCOL bites hardest
State averages blend expensive cities with cheap rural counties, so they understate how pricey the top metros really are. A cleaner way to feel it is purchasing power: how much a national $100 actually buys locally.
| Metro area | Real value of $100 | Effect |
|---|---|---|
| San Francisco-Oakland-Berkeley, CA | $84.58 | Costs ~18% more than average |
| Los Angeles-Long Beach-Anaheim, CA | $86.61 | Costs ~15% more than average |
| New York-Newark-Jersey City, NY-NJ-PA | $88.91 | Costs ~12% more than average |
| Urban Honolulu, HI | $90.71 | Costs ~10% more than average |
| Pine Bluff, AR (cheapest metro) | $124.49 | Costs ~20% less than average |
Source: Tax Foundation, "Purchasing Power Map: Real Value of $100 by Metro, 2023," using BEA Regional Price Parities. A lower dollar figure means the metro is more expensive. San Jose, Boston, Seattle, San Diego, and greater Washington DC all sit in the same HCOL tier as these leaders.
How HCOL changes your FIRE number
FIRE math is simple: your number is your annual spending divided by your safe withdrawal rate. At the classic 4% rule, that is 25 times annual spending. The catch is that annual spending is not fixed. It scales with local prices, and the RPP tells you by how much.
Take a lifestyle that costs $200,000 a year at national-average prices. Here is what the same real lifestyle costs, and the portfolio it demands at 25x, across the price map.
| Location (2024 RPP) | Cost to replicate $200k lifestyle | FIRE number at 25x |
|---|---|---|
| California (110.7) | ~$221,400 | ~$5.54M |
| New Jersey (108.8) | ~$217,600 | ~$5.44M |
| National average (100) | $200,000 | $5.00M |
| Mississippi (87.0) | ~$174,000 | ~$4.35M |
| Arkansas (86.9) | ~$173,800 | ~$4.35M |
Illustrative, using 2024 BEA state RPPs applied to a $200,000 baseline and a 4% withdrawal rate. Moving the identical lifestyle from California to Arkansas cuts the required portfolio by roughly $1.2M. That is the entire premise of geoarbitrage: you are not lowering your standard of living, you are lowering the price you pay for it. If you want to pressure-test your own target across scenarios, start with our FatFIRE net worth benchmarks and the financial independence framework.
Two honest caveats. First, RPP is an all-items average, and the single biggest driver of the gap is housing rent, not groceries or gas. If you already own your home outright or your spending skews toward travel and discretionary line items that are not location-bound, your personal cost gap is smaller than the headline RPP suggests. Second, these figures assume you actually replicate the same basket. Many people who move to LCOL areas simply spend the surplus.
The geoarbitrage and tax overlay
Cost of living is only half the map. The other half is state income tax, and the two do not always move together.
Nine states levy no tax on wage income: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire completed the phase-out of its interest-and-dividends tax, so investment income is untaxed at the state level starting with the 2025 tax year. Washington is the outlier: no wage tax, but it does levy a 7% tax on long-term capital gains above an annual threshold, which matters if your FIRE income is largely realized gains. Source: state revenue departments and Tax Foundation, 2026.
The overlay is what makes this powerful for a FatFIRE portfolio:
- Florida and Texas combine no income tax with roughly average or below-average price levels. You get the tax break without paying HCOL rents.
- South Dakota, Tennessee, and Wyoming pair no income tax with genuinely low cost of living.
- Washington and, at the metro level, the Seattle area, give you no wage tax but HCOL prices and a capital gains tax, so the win is narrower.
- California and Hawaii deliver the worst of both for high earners: top-tier prices and among the highest state income tax rates in the country.
For a retiree living on portfolio withdrawals rather than a paycheck, the interaction of capital gains treatment, property tax, and price level often matters more than the headline income-tax rate. Florida is a common landing spot for exactly this reason, and we break the numbers down in average retirement income in Florida.

The bottom line
The HCOL map is not trivia. It is a lever on the single most important number in your plan. The BEA RPP shows a roughly 24-point spread between the priciest and cheapest states, and a wider one across metros. Applied to a FatFIRE lifestyle, that spread is worth seven figures in required capital. Layer the no-income-tax states on top, and a deliberate choice of geography can pull your FIRE date forward by years without cutting a single thing you actually enjoy.
Frequently asked questions
What is the most reliable measure of US cost of living by area?
The most reliable measure is the Bureau of Economic Analysis Regional Price Parity (RPP), a government-backed index where the national average equals 100. Anything meaningfully above 100 is high cost of living, and anything below is low or medium cost. It is the cleanest single number because it is consistent, updated annually, and built from the same federal price data nationwide, unlike crowdsourced maps with no auditable methodology.
Which US states have the highest and lowest cost of living?
In 2024 the priciest states were California at 110.7, Hawaii at 110.0, and New Jersey at 108.8, with the District of Columbia at 109.9. The cheapest were Arkansas at 86.9, Mississippi at 87.0, and Iowa and Oklahoma both at 87.8. That is roughly a 24-point spread between the priciest and cheapest states, per BEA data released February 19, 2026.
How much does a high cost of living change your FIRE number?
Cost of living can swing your FIRE number by seven figures. Replicating a $200,000 national-average lifestyle costs about $221,000 in California but roughly $174,000 in Arkansas. At a 4% withdrawal rate, that is the difference between a $5.54 million and a $4.35 million portfolio, so moving the identical lifestyle from California to Arkansas cuts the required portfolio by roughly $1.2 million.
Which states have no income tax and low cost of living?
South Dakota, Tennessee, and Wyoming pair no income tax with genuinely low cost of living, stacking two tailwinds for FIRE geoarbitrage. Florida and Texas combine no income tax with roughly average or below-average price levels. Washington is narrower: no wage tax but high cost of living prices and a 7% tax on long-term capital gains above a threshold. Nine states in total levy no tax on wage income.
Does the cost of living gap between states apply to everyone equally?
No, the gap does not apply equally, because RPP is an all-items average driven mostly by housing rent rather than groceries or gas. If you already own your home outright or your spending skews toward travel and discretionary items that are not location-bound, your personal cost gap is smaller than the headline RPP suggests. The figures also assume you actually replicate the same basket rather than spending the surplus.
