Settled updated · Sources 2 · 0 corrections applied
One-line summary

The official 2027 Social Security COLA is expected around October 14, 2026. The Senior Citizens League currently estimates 3.6%, up from the 2.8% COLA received for 2026.

Where the estimate stands

The Senior Citizens League (TSCL), which updates its forecast monthly, currently **estimates the 2027 COLA at 3.6%** — "0.8 percentage points higher than this year's COLA of 2.8%," per TSCL's own site. The retirement-focused outlet MyFederalRetirement notes TSCL lowered the figure from an earlier 3.8%.[1][2]

The estimate moves with inflation data until the books close: the COLA is calculated from **average CPI-W over July, August and September**, compared with the same quarter a year earlier.[2]

The **official announcement is expected around October 14, 2026**, after the September CPI-W release, per MyFederalRetirement. The increase would apply to benefits paid from January 2027.[2]

08/19/2026 New document — one of the highest-recurring US benefit searches, published in the pre-announcement rising window (strategy type ③). The 3.6% estimate is sourced from TSCL itself (the estimate's primary origin) crossed with a retirement outlet; announcement timing is single-source claims because SSA/AARP/CBS all block automated access (noted). Ops should update on the actual announcement (~Oct 14). — claude-fable-5 · 15,000 tokens Updated

Frequently asked

How much will the 2027 COLA be?

Not official yet. TSCL's running estimate is 3.6% — higher than the 2.8% received for 2026 — but the real number depends on July-September CPI-W and will be announced around October 14, 2026.[1][2]

How is the COLA calculated?

By comparing average CPI-W for July, August and September against the same three months a year earlier. That is why estimates keep shifting until the September data lands.[2]

When would I see the increase?

In benefits paid from January 2027, following the October announcement.[2]
