One percentage, applied everywhere
The COLA is produced by a single calculation: the national CPI-W for the third quarter of the current year, compared with the third quarter of the prior year. The result is one percentage, announced once, applied to every benefit in the program. For 2027 it is 3.6%, effective with December 2026 benefits paid in January 2027.
There is no state index, no regional adjustment, and no separate announcement. A beneficiary in one state and a beneficiary in another with the same benefit amount receive the same dollar increase.
| Element | Uniform nationally | Varies by state |

| COLA percentage | 3.6% | — |
| Base for the calculation | CPI-W, national | — |
| Payment date rule | Birth date / 1st of month | — |
| State income tax on benefits | — | Yes |
| Local cost of living | — | Yes |
What actually differs by state
Two things vary, and neither is the COLA.
State income tax treatment. States define their own tax base. Some exempt Social Security benefits entirely, some tax them using federal provisional income, and some use their own thresholds. The result is a difference in what you keep, not in what SSA pays.
Cost of living. Housing, health care and utilities differ by geography, so the same 3.6% buys different amounts in different places. That is a real difference and a different subject.
A table that lists 50 percentages is therefore describing neither of these accurately. It is usually average benefit levels relabeled, or state tax rules converted into a fictitious rate.
The distinction matters for planning. A state tax change alters what you keep and shows up on a state return. A COLA change alters your gross benefit and shows up in your SSA notice.
The dollar effect of 3.6%
The increase is applied to your own benefit, so the amount depends on your record, not your address:
- A $1,000 monthly benefit rises by $36.
- A $2,000 monthly benefit rises by $72.
- The average retired-worker benefit of $2,170 rises to about $2,248.
Those figures are the same in every state. The 2027 maximum benefit at full retirement age is $4,188, also a national figure.
How to check a state COLA claim
Find the COLA fact sheet and confirm the announced percentage. Then ask what the state table is measuring. If it lists a percentage per state, compare it with 3.6%; a different number is not a COLA, whatever the table is called.
For the personal figure, use the COLA calculator on this site or read the amount in my Social Security after the December 2026 benefit is processed. Your state appears nowhere in that calculation.
