The 2027 cost-of-living adjustment (COLA), Social Security's yearly inflation increase, raises future benefits for workers who are already 62. The 3.6% amount is added to their primary insurance amount, the base benefit figure, even if they delay claiming. The SSA Office of Inspector General reports the increase was announced Oct.
14, 2026, based on CPI-W growth from Q3 2025 to Q3 2026 and covering about 76 million beneficiaries, in its 2027 COLA announcement summary. Current retired workers receive it with January 2027 payments. Investopedia reports the average monthly check rises by about $75, from roughly $2,095 to $2,170.

Do you get it if you have not claimed?
Yes, if you are already 62. SmartAsset explains each annual COLA is added to the primary insurance amount even before filing, in its future-retiree COLA guide. Filing later does not forfeit the 2027 increase.
It stays in the base used to calculate the later monthly payment. That matters for planning around a later start date. A higher base means later adjustments compound from a higher level. A worker comparing claim ages should treat the COLA as already banked at 62 and older.
What happens if you wait until 70?
Waiting lets COLAs stack inside the benefit base. A worker who turns 62 and waits until 70 accumulates about eight years of COLAs before delayed-retirement credits further raise the monthly amount. LegalClarity describes that eight-year buildup in a 2026 explainer.
The practical effect is compounding, not a one-time bump. Each year's percentage applies to a base that already includes prior COLAs. Delayed-retirement credits then apply on top of that COLA-enlarged base.

Why does age 62 draw the line?
COLAs do not apply before age 62. LegalClarity explains pre-62 earnings are indexed to average wages instead in the future-benefit calculation. A worker under 62 therefore gets no 2027 COLA added to a future benefit.
This is a sharp boundary for younger planners. Wage indexing still adjusts earlier earnings for economy-wide wage growth. But only after 62 does the inflation COLA begin to raise the primary insurance amount year by year.
What can shrink the net gain?
Two offsets deserve attention. Highline Planning, citing the Medicare Trustees projection, puts 2027 Medicare Part B at $209.50 versus $202.90 in 2026, with Part B usually withheld from the check, and notes income-tax thresholds are not inflation-indexed, in its 2027 COLA and offset analysis. The nominal Social Security gain can therefore shrink after health premiums and taxes.
Higher earners face a related change. The Journal of Accountancy reports the 2027 taxable maximum rises to $192,300 from $184,500 in 2026. Those earners pay 6.2% Social Security tax longer and can credit more earnings toward future benefits.
- Compare claim ages using the COLA-enlarged base, not last year's benefit estimate.
- Check the projected Part B withholding against the higher gross benefit.
- Review taxable income, since more of the check can become subject to tax.
