Your Social Security COLA could go up another $71 per month in 2027. That’s not necessarily good news.

A higher Social Security cost-of-living adjustment (COLA) can look like a raise, but it is really an inflation signal. If estimates point to roughly $71 more per month in 2027, that figure reflects faster growth in the price index used to calculate the adjustment—not an improvement in retirees’ real purchasing power. The COLA mechanism is designed to keep benefits level in inflation-adjusted terms, so a larger bump often means the underlying cost of living rose more sharply.

For markets, the relevance runs through inflation expectations and interest rates. A persistently elevated COLA trend suggests price pressures are not fully contained, which can influence how investors think about Federal Reserve policy, bond yields, and rate-sensitive sectors. It can also shape expectations for other inflation-linked payments and contracts.

What to watch: the official inflation data that feed the COLA formula, any revisions to those estimates before the final number is set, and whether other inflation gauges confirm the same trend. The key takeaway is that a bigger COLA is a symptom, not a windfall.
