The Iran War Just Added Roughly Two Percentage Points to Your 2027 Social Security COLA Estimate. Here’s the Math.

Seniors who get most or all of their retirement income from Social Security tend to rely on the program’s annual cost-of-living adjustments, or COLAs, in a really big way. Without those COLAs, seniors would be pretty much guaranteed to lose out on buying power from year to year.

At the start of 2026, Social Security benefits got a 2.8% COLA. And many seniors are no doubt hoping for a more generous raise in 2027.

Earlier this year, that didn’t seem likely. But the Iran conflict has changed the math quite a bit. Whether that’s a good thing or not, though, is questionable.

How a major conflict changed the COLA equation

You may be wondering what the war in Iran has to do with Social Security’s upcoming COLA. The answer boils down to inflation.

The conflict overseas began in late February. Shortly after it started, Iran moved to close the Strait of Hormuz — a critical passageway responsible for a vast amount of oil and gas shipments.

That closure has driven the price of oil up significantly. Brent crude prices surged past $120 per barrel in early March and were still hovering around $114 as of late April.

In the U.S., gas prices have risen about $1.20 per gallon since the start of the war. As of late April, the average price per gallon was well above $4.20 on a national scale.

Those price increases didn’t stay confined to the pump, though. They’ve also impacted the cost of goods broadly. As a result, there’s been a notable uptick in inflation.

In March, the Consumer Price Index showed a 3.3% year-over-year increase. Because Social Security COLAs are tied to inflation, these cost increases could potentially be setting the stage for a larger boost in 2027.

What the new numbers looks like

The Senior Citizens League thinks next year’s Social Security COLA will be 2.8% — the same raise as in 2026 — even after accounting for March’s inflation reading. But following March’s data, independent Social Security analyst Mary Johnson revised her estimate for the 2027 COLA.

Initially, Johnson pegged that increase at 1.2% based on January inflation data. Based on March’s data, her COLA projection is now 3.2% — a full two percentage-points higher.

What a larger COLA actually means for you

If you’re a retiree on Social Security, you may be hoping for a larger COLA in 2027. But in reality, that may not be such a positive thing.

While it’s true that a 3.2% raise might boost your benefits quite a bit, what you gain in the form of larger monthly checks, you’re apt to lose in the form of higher costs.

Remember, COLAs are just a response to inflation. They’re not meant to improve your finances. So the same surge in prices that could lead to a larger COLA might also put a strain on your wallet.

Of course, it’s too soon to know with certainty what next year’s Social Security COLA will amount to. Those raises are based on third quarter inflation data.

But if costs continue to increase or remain elevated, inflation could persist in the 3% range or higher through the third quarter of the year, leading to a larger COLA in 2027. Unfortunately, it may not end up doing seniors on Social Security a whole lot of good.
