Every state-to-state cost comparison starts with the same question: how much more (or less) does the same stuffcost in a different place? The answer comes from the Bureau of Economic Analysis's Regional Price Parities (RPP) — the official US government measure of price level differences, built from actual price surveys in every state. Every number below is reproducible in our relocation cost calculator.
1. What BEA price parities actually measure
RPPs express each state's price level as a percentage of the national average (100). A state at 110 means the same basket of goods and services costs 10% more than the national average; a state at 87 costs 13% less. The 2024 release covers all 50 states plus DC and is updated annually from price surveys spanning groceries, housing, transportation, healthcare, and services.
2. The 27% spread: cheapest to most expensive
California is the most expensive state at 110.7, followed by Hawaii (110.0) and DC (109.9). Arkansas is the cheapest at 86.9, with Mississippi (87.0) and Iowa (87.8) close behind. The gap between the extremes — $5,000/month in Arkansas translates to about $6,362/month in California — is a $1,362 monthly difference, or $16,344 per year, for the identical lifestyle.
3. Three worked moves, real dollar amounts
California → Texas ($5,000/month): factor = 97.1 ÷ 110.7 = 0.877. The same lifestyle costs about $4,386/month in Texas — saving $614/month or $7,371/year.
Mississippi → New York ($4,000/month): factor = 107.9 ÷ 87.0 = 1.240. The same lifestyle costs about $4,961/month in New York — a 24% increase that means finding $960 more per month just to stand still.
Ohio → Florida ($4,500/month): factor = 103.4 ÷ 92.8 = 1.114. Expect about $5,014/month in Florida — $514 more per month, the kind of increase that feels manageable until you multiply by twelve ($6,168/year).
4. The factor most comparisons miss: housing
State-level RPPs blend everything together, but housing costs vary far more than groceries or gas. California's overall RPP is 110.7, but its housing rentsRPP is 154.3 — meaning rent specifically is 54% above the national average while other categories are closer to 10-15% above. The reverse is also true: West Virginia's housing RPP of 54.2 means rent is nearly half the national average even though the state's overall RPP is 89.5. If rent is your biggest line item, the overall RPP understates your actual cost difference.
5. The double whammy: state income tax
RPPs don't include income tax — and that's where relocations get expensive. Nine states (Texas, Florida, Washington, Nevada, and others) have no state income tax on wages. Moving from one of those to California adds roughly 9.5% effective state tax on top of the higher cost of living. A $100,000 earner moving from Texas to California faces a 10.7% higher cost of living AND ~$8,000/year in state income tax — a combined hit of nearly 19% to their real standard of living.
6. Run your own numbers
Pick your two states, enter your actual monthly expenses and take-home income, and the relocation cost calculator shows the adjusted cost, the monthly and annual gap, and whether your income covers it. If you're still deciding whether the move makes sense at all, the two-minute quiz weighs cost, income portability, taxes, and your financial cushion into a verdict.
