The 2027 Social Security increase has not been officially set yet. Current estimates in the news range from about 3.8% to 4.7% , with one recent report citing 4.7% as a possibility and the official announcement expected in October 2026.

What that means

A 3.8% to 4.7% COLA would be a noticeably larger raise than the 2.8% increase beneficiaries got for 2026. In simple terms, if someone’s monthly benefit were $2,000, a 3.8% boost would add about $76, while a 4.7% boost would add about $94.

Why it can change

The annual Social Security COLA is tied to inflation data, so the final number can move as new price data comes in before the official calculation. That means early projections are useful, but they are still only estimates until Social Security announces the figure.

Bottom line

Right now, the safest answer is: expect something in the high-3% to mid-4% range, but the exact 2027 increase is still pending.
