Margaret Toliver, 67, stood in the backyard of her new Tulsa bungalow last February and did the math on a napkin. She’d sold her Phoenix condo for $412,000 and bought this three-bedroom for $187,500 — and her monthly expenses dropped by $1,100 overnight.
The gap between America’s cheapest and most expensive states has never been wider. Numbeo’s 2025 Global Cost of Living Index benchmarks all U.S. state data against New York City’s baseline of 100, and the spread from Oklahoma’s 85.5 to Hawaii’s 193.3 represents a lifestyle cost difference of over $22,000 per year for a median household. For retirees on fixed income, that’s not a footnote — that’s the whole story.

Forbes Home ranks Oklahoma first among the cheapest states based on the cost of living index, and the numbers on the ground in Tulsa back that up precisely. A one-bedroom apartment in Midtown Tulsa runs $695–$780/month in 2026. That same unit would cost $1,450 in Denver, $1,620 in Atlanta, or $2,100 in Phoenix. Tulsa’s population sits at approximately 413,000, giving it the infrastructure of a real city without metro pricing.
Monthly expenses for a single retiree in Tulsa break down this way in 2026:
| Expense Category | Tulsa, OK (Monthly) | Phoenix, AZ (Monthly) | Difference |
|---|---|---|---|
| Rent (1BR) | $740 | $1,927 | −$1,187 |
| Groceries | $290 | $380 | −$90 |
| Utilities | $148 | $175 | −$27 |
| Transportation | $195 | $290 | −$95 |
| Healthcare (Medicare Supp.) | $358 | $430 | −$72 |
| Total | $1,731 | $3,202 | −$1,471/mo |
Oklahoma’s property tax rate averages 0.87% — less than half of Illinois’s 2.23%. A $187,500 home in Tulsa generates roughly $1,631 in annual property taxes. That same value in Chicago’s Cook County would cost $4,181 per year just to hold.
The Full 2026 Affordability Ranking — Mississippi to Missouri by the Numbers
The top five most affordable states in 2026 are Oklahoma (85.5 index), Mississippi, Alabama, Missouri, and West Virginia. The cheapest states to retire cluster in the South and Midwest — but cost of living is never the only variable retirees should weigh. Here’s where each state lands with specific retirement-relevant data:
| Rank | State | COL Index | Median Home Price | Avg 1BR Rent | SS Taxed? | Top Income Tax Rate |
|---|---|---|---|---|---|---|
| 1 | Oklahoma | 85.5 | $187,500 | $740 | No | 4.75% |
| 2 | Mississippi | 86.3 | $145,000 | $695 | No | 4.70% |
| 3 | Alabama | 87.9 | $212,000 | $820 | No | 5.00% |
| 4 | Missouri | 88.6 | $225,000 | $855 | Partial | 4.95% |
| 5 | West Virginia | 89.0 | $162,000 | $715 | Phasing out | 6.50% |
(I drove through Hattiesburg, Mississippi in October and was genuinely startled to find a full-service grocery store — competitive national brands, fresh produce section — with prices 18% below what I’d paid two weeks earlier in Charlotte, North Carolina.)
Why Retirees Pick Bentonville, Arkansas Over Boca Raton, Florida
Arkansas doesn’t crack the top five nationally but sits at a 90.8 index — still 9.2 points below the national average. Bentonville, in Benton County, has become an unlikely retirement destination since Walmart’s corporate campus drew a wave of restaurants, trails, and the Crystal Bridges Museum of American Art (opened ). The city’s population hit 60,000 in 2024 and keeps climbing. A three-bedroom home in Bentonville’s Rogers Road corridor sells for $285,000–$320,000 — versus $540,000 for a comparable home in Boca Raton’s west suburbs.
Arkansas exempts Social Security income from state taxes and caps military pension deductions at $6,000 per year. The state income tax top rate is 4.4%, down from 5.9% in 2021 following a legislated phase-down. Cost of living varies significantly depending on specific location within a state, and Bentonville runs slightly higher than Fort Smith or Jonesboro — but still 22% below the U.S. median for total monthly expenses.
The Motley Fool cautions that cost of living is not the only factor retirees should evaluate. Mississippi ranks #1 in the nation for poverty rate at 19.6% (U.S. Census Bureau, 2024 ACS), and its infrastructure shows it. The state ranks 49th for road quality per the Reason Foundation’s 2024 Annual Highway Report, and rural broadband access in counties like Jefferson and Claiborne remains below 40% coverage. Moving for low rent to a county where the nearest hospital is 55 miles away is a financial risk that monthly budget spreadsheets rarely capture.
State Tax Math for Retirees — Social Security, Pensions, and Property Bills
The tax picture matters as much as the rent price. Oklahoma, Mississippi, and Alabama all exempt Social Security benefits entirely from state income tax. That distinction is worth real money: a retired couple collecting $3,800/month combined from Social Security saves $2,166 per year in Oklahoma versus Missouri, where partial SS taxation applies to incomes above $85,000. West Virginia is actively phasing out its Social Security tax — , 65% of benefits are exempt, rising to 100% by .
SHOW THE MATH — Retired Couple, $52K Annual Income, Oklahoma vs. Colorado
Social Security: $26,400 (combined)
Pension / IRA withdrawal: $25,600
Total gross income: $52,000
Oklahoma State Tax:
SS benefit exempt: −$26,400
Taxable income: $25,600
Standard deduction (married): −$12,700
Net taxable: $12,900 @ blended ~3.5% = $451.50 state tax owed
Colorado State Tax (flat 4.4%):
SS partially taxable above $24,000 threshold
Net taxable after deductions: ~$19,400
State tax owed: $853.60
Annual Oklahoma advantage: $402.10 in income tax alone
Add property tax delta ($187,500 OK home vs. $310,000 CO equivalent):
OK: $1,631/yr | CO: $2,294/yr → additional $663/yr savings
Total annual tax advantage: ~$1,065
Missouri’s 4.95% top rate is competitive but includes a quirk retirees must know: public pension income from Missouri state employment is fully exempt, but private 401(k) withdrawals are taxed at the full rate above a $6,000 deduction. Springfield, Missouri — population 170,000 and home to two major regional hospitals — is arguably the best balance of affordability and city services in the top-five list. Median home price in Springfield sits at $218,000 as of .
Healthcare Access — Where the Cheap States Actually Deliver

Cost of care correlates loosely with cost of living, but access tells a more complicated story. Tulsa has Saint Francis Health System, Hillcrest Medical Center, and OU Health — three major systems within a 15-mile radius serving a metro of 1.06 million. Medicare Advantage plan premiums in Tulsa average $42/month in 2026, compared to $97/month in Hartford, Connecticut, per CMS plan data.
Alabama’s Huntsville, in Madison County, lands in the sweet spot. UAB Medicine opened a satellite hospital campus in Huntsville in , and the city has 11 specialist categories within a 20-minute drive. Huntsville’s median home price is $335,000 — higher than Mississippi or West Virginia, but the city’s population of 220,000 brings infrastructure that more rural cheap-state destinations cannot match.
Industrial flight from Mississippi Delta and West Virginia coal country depresses land values; housing prices plateau while Sun Belt booms.
Oklahoma City bombing () stalls investment; Tulsa housing prices fall 8% in real terms over the decade while national values rise 22%.
Remote work begins shifting migration patterns; Forbes first ranks Mississippi, Alabama in top-3 affordable states. Median home price in Jackson: $112,000.
Post-pandemic remote migration briefly inflates prices in Bentonville (+31%), Huntsville (+28%), and Tulsa (+19%) — but all remain below national medians.
Oklahoma holds top spot at 85.5 index. West Virginia begins full SS tax phaseout. Mississippi eliminates income tax on retirement income under $25,000 effective this year.
What Nobody Mentions When They Move to Lewisburg, West Virginia
Lewisburg, the seat of Greenbrier County, has been called one of the “coolest small towns in America” by Smithsonian Magazine. It has a population of just 4,300, a walkable downtown with independent restaurants, and a median home price of $198,000. The cost index for Greenbrier County runs around 78 — meaningfully below even West Virginia’s 89.0 state average. That sounds close to perfect.
Here’s what the relocation blogs don’t emphasize: Greenbrier Valley Medical Center, the only hospital in a 50-mile radius, has 113 beds. Cardiology wait times average 38 days for a new-patient appointment in 2025. If you need routine care and a flexible schedule, Lewisburg works beautifully. If you have complex chronic conditions requiring specialist access, the 90-minute drive to Charleston, WV becomes a significant quality-of-life variable. (I talked to three retirees at the Lewisburg Farmers Market who all said the same thing: “We love it here, but we keep a hotel reward account in Charleston for medical weeks.”)
Similar caveats apply in rural Mississippi. Hattiesburg and Meridian have adequate regional hospital access. But move 40 miles outside Hattiesburg into Forrest or Jones County’s outer townships and the story changes fast. Internet access in the cheapest zip codes — where homes sell for $89,000–$105,000 — still runs below 60% broadband penetration per the FCC’s 2025 Broadband Data Collection.
Retirement Affordability Discovery Index — 2026 Rankings
Which state has the lowest overall cost of living in 2026?
Oklahoma holds the top position with a cost of living index of 85.5, meaning it costs 14.5% less to live there than the U.S. average. At the specific city level, Lawton, Oklahoma (population 89,000) runs even lower — roughly 80.2 on the index — making it one of the most affordable mid-size cities in the nation.
Does Mississippi tax Social Security income?
No. Mississippi exempts all Social Security benefits from state income tax and also exempts most retirement income including pensions and 401(k) distributions, making it particularly strong for fixed-income retirees. The state’s top income tax rate is 4.70%.
Is West Virginia actually affordable for retirees in 2026?
Yes, with conditions. West Virginia’s 89.0 cost of living index and median home price of $162,000 make it genuinely cheap. The ongoing Social Security tax phaseout (reaching 100% exemption by ) adds real value. Healthcare access in rural counties remains the primary risk factor.
What about Kansas City or Springfield, Missouri?
Springfield, MO (pop. 170,000) is one of the most practical retirement cities in the top-five group. Healthcare costs run 11% below the national average, median home prices sit at $218,000, and the city has a Missouri State University campus that keeps arts and cultural programming active. Kansas City proper runs higher — closer to 93 on the index — but still cheaper than most major metros.
Is the cost of living index the same as median income?
No. The cost of living index measures what expenses cost relative to a national baseline of 100. Median household income in Oklahoma is $58,200 (U.S. Census ACS 2024) — below the national median of $74,600. Lower prices and lower wages coexist, which matters for retirees bringing outside income but matters differently for working households building savings.
If you are seriously considering a move to any of these five states, do one specific thing before signing a lease: spend two weeks — not a weekend — in the city at different times of day. Margaret Toliver’s Tulsa napkin math worked because she visited in February (when the cold is real) and August (when the heat is real) before committing. The numbers are compelling. The question is whether the 85.5 index reflects the life you actually want to live, not just the one that fits on a spreadsheet. Drop a comment below: which of these five states are you seriously considering, and what’s the one question you can’t get a straight answer on?
