Why October 14 matters for Social Security retirees

For anyone who is collecting Social Security benefits, including retirement, survivor, and spousal benefits, October 14 is the most important date of the year.

This day belongs on your calendar because it is the day that you'll find out your official cost-of-living Adjustment (COLA).

COLAs are awarded in most years to ensure that benefits don't lose buying power because of price increases that happen over time. Without these adjustments, inflation would eat away at the real value of Social Security benefits, leaving seniors struggling.

In 2026, the COLA was 2.8%, but retirees can't find out what their COLA for 2027 is until October 14.

Why is October 14 the key date?

So, why is October 14 the critical date when retirees find out their COLA? It's because of how cost-of-living adjustments are calculated.

Specifically, COLAs are calculated based on the average changes to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). But the Social Security Administration only uses third quarter CPI-W data to calculate the COLA.

If the CPI-W numbers in July, August, and September show prices increased year-over-year, Social Security recipients get a cost-of-living adjustment equal to the percentage increase in the average CPI-W for the third quarter compared with the average CPI-W for the third quarter of the previous year.

The Bureau of Labor Statistics collects this data, and the September numbers are scheduled to be released on October 14, 2026.

COLA estimates are out already, but the numbers aren't official

Retirees won't find out the official COLA amount until the CPI-W numbers for September come out in October, but we already have some data from the first few months of 2026. And this data shows a clear trend: Prices are increasing.

In recent months, inflation has surged to the highest level in three years, largely driven by increases in energy costs linked to the Iran war. Because inflation is trending high, experts predict that the 2027 COLA could be one of the highest COLAs in recent years.

Early projections from the Senior Citizens League estimate the COLA at 3.8%, up from 2.8% this year. If retirees are on track for such a large benefit increase, knowing the official figure could help them better plan for the coming year. That's why marking the calendar for October 14 is so important.

A large COLA isn't always a good thing

Retirees should pay attention to the COLA amount because it is an indicator of how costs are trending.

While a big raise is normally a good thing when you're working, it's not a positive thing for an inflation adjustment to be large. And that's ultimately what a COLA is. While it's called a raise, its purpose is to adjust benefits up based on the specific rate of inflation as measured by the CPI numbers.

Higher-than-average levels of inflation tend to be a bad thing for seniors because much of their money is likely in cash or conservative investments, as they don't want to take on too much risk when they are living on their retirement accounts.

Their income sources outside of Social Security, therefore, are likely to lose a lot of buying power when inflation levels are high, and they may face more financial struggles.

Do COLAs help retirees keep pace with inflation?

It's also worth noting that the COLA formula is imperfect, so Social Security benefits aren't necessarily keeping up with inflation even though they are supposed to.

The Senior Citizens League estimates that benefits have lost 13.7% of buying power since 2016 alone. This is happening because the COLA formula focuses on the spending habits of urban wage earners and clerical workers and isn't a perfect measure for the inflation retirees experience.

This makes it even more important for retirees to pay attention to the COLA announcement. When the CPI-W number shows surging inflation, the actual inflation they're experiencing is likely even more extreme. Making a careful financial plan for the upcoming year is critical under these conditions.

Bottom line

Whether you are living on just Social Security or use Social Security to help cover the bills, you must pay attention to the COLA announcement on October 14. It is going to offer important insight into how your benefits are changing in 2027 as well as insight into the inflation you're likely to experience.

While trends change over time, if inflation continues to be high throughout the third quarter of the year, this suggests that you may need to make some adjustments to your budget to ensure you're able to still live comfortably on the income that your benefits and investment account withdrawals provide.
