Social Security’s COLA Increase is The Same For All States, but Can Buy 27% More in Mississippi Than California

Millions of Americans receiving Social Security benefits are getting a 3.6% cost-of-living adjustment in 2027, but the purchasing power of that increase will depend heavily on where they live.

For the average retired worker, the adjustment translates into approximately $75 more per month, or $900 annually. Yet that additional money can stretch considerably further in Mississippi than in California or New York, according to data from the U.S. Bureau of Economic Analysis (BEA).

Based on the BEA's 2024 regional price parity data, the same amount of money has approximately 27% more purchasing power in Mississippi than in California and 24% more than in New York.

Those differences mean retirees receiving identical benefit increases may experience substantially different financial relief depending on their location. The Social Security Administration announced the adjustment Wednesday, saying nearly 72 million beneficiaries will receive higher payments beginning in January.

Another 7.3 million people receiving Supplemental Security Income will see their payments increase starting December 31, although some individuals receive both benefits. The average monthly retirement benefit will climb from $2,095 to $2,170.

For couples who both receive benefits, the average combined payment will increase from $3,238 to $3,355. The regional purchasing-power differences become clearer when comparing the BEA's latest available Regional Price Parity indexes, which measure how expensive goods and services are in each state relative to the national average.

In 2024, Mississippi recorded a price index of 87.0, meaning overall prices were approximately 13% below the national average. California's index reached 110.7, indicating prices roughly 10.7% above the national average.

Using those indexes, $75 in Mississippi could purchase approximately the same overall basket of goods and services as $95.43 in California. Put differently, the purchasing power of $75 in California was equivalent to approximately $58.94 in Mississippi.

That gives Mississippi about 27.2% more purchasing power than the same nominal amount in California. A similar comparison with New York suggests a purchasing-power advantage of approximately 24%, based on the state price levels used in the analysis.

Housing accounts for much of the disparity. According to the BEA, California's housing-rent price index reached 154.3 in 2024, more than 54% above the national average. Housing costs are frequently the largest factor driving differences in overall regional prices.

The comparison also uses 2024 regional price levels, released in February 2026, rather than projected prices for 2027. It illustrates differences in purchasing power, not how much inflation will rise in each state next year. The BEA's next regional price data release is scheduled for December 10.

The 2027 COLA is higher than the 2.8% adjustment beneficiaries received in 2026. Social Security calculates the annual increase using the Consumer Price Index for Urban Wage Earners and Clerical Workers, which rose an average of 3.6% during the third quarter compared with the same period last year.

Still, the adjustment arrives as retirees face renewed pressure from inflation. The Bureau of Labor Statistics reported Wednesday that consumer prices increased 3.7% over the previous 12 months, while an AARP survey found that approximately three-quarters of adults aged 50 and older questioned whether a hypothetical 3.5% COLA would sufficiently cover rising expenses.
