2027 COLA Forecast for Military Retirees: Iran, Tariffs, and Your Pay

Your 2027 COLA is shaping up to be one of the biggest in years. In January, one independent analyst pegged it at 1.2%. By April she was at 3.2%. By June, 4.7%, and the seniors group that runs the most-watched forecasting model is at 3.8%. The reason: gas prices above $4 a gallon, tariff-driven goods inflation, and the biggest oil supply disruption since the 1970s, all of it now showing up in the official CPI-W data.

The official number won't land until October 2026, but the data released so far tells a clear story. If you're a military retiree, a surviving spouse receiving SBP annuity payments, or a veteran drawing VA disability, the 2027 COLA will affect every check you receive starting in January 2027.

Here's where the forecast stands right now, what's driving it, and how much it could add to your monthly pay.

The Current 2027 COLA Forecast: 3.8% to 4.7%

Two groups publish widely followed COLA estimates. They currently disagree, and the gap between them says a lot about where this is headed.

The Senior Citizens League uses a statistical model that factors in CPI, the Federal Reserve interest rate, and unemployment. Their model sat at 2.8% through April, jumped to 3.9% in May, and settled at 3.8% in June. That is the conservative end of the range.

Mary Johnson, an independent Social Security and Medicare policy analyst, has revised her forecast upward five months running: 1.2% in February, 1.7% in March, 3.2% in April, and 4.7% by mid-June. The original driver was the March energy spike (energy prices jumped 10.9% in a single month, the largest since September 2005, with gas up 21.2% between February and March). The data since then has kept proving her right.

In June she went further: there is "a considerable likelihood that it's going to climb even higher than 4.7% as data continues to come in, especially on the gasoline prices."

The Congressional Budget Office's forecast of 3.1% for 2027 dates to April, before the spring energy data landed, and now looks low.

The Hard Numbers So Far: CPI-W Through May

The Bureau of Labor Statistics has released three CPI-W readings since the spring energy spike began. Each one has come in hotter than the last:

The 2027 COLA is set by the average CPI-W from July, August, and September 2026, compared against the Q3 2025 baseline of 317.265. None of the months above count directly. But May's reading sits 3.6% above the baseline before the counting quarter even starts: if prices simply froze at May's level through September, the COLA would land near 3.6%. TSCL's model expects a touch more at 3.8%. Johnson expects gas prices to keep pushing, hence 4.7%.

What's driving it, per the 12-month CPI-W detail: fuel oil up 64.1%, gasoline up 40.7%, and airfare up 25%. Unless those reverse hard during the third quarter, the arithmetic points above the May reading, not below it. The May 2026 report also marked the fastest 12-month CPI-W pace since April 2023.

How the Military COLA Is Calculated

Military retirement COLA follows the exact same formula as Social Security COLA. There's no separate military calculation. If Social Security gets 2.8%, military retirees get 2.8%. (The one exception: REDUX retirees get COLA minus 1 percentage point.)

The formula:

1. The BLS calculates the average CPI-W for Q3 (July, August, September) of the current year
2. That average is compared to the Q3 average from the prior year (the "baseline")
3. The percentage increase, rounded to the nearest tenth, becomes the COLA
4. COLA is announced in mid-October
5. The increase takes effect December 1
6. Military retirees see it in their January payment

For 2027, the baseline is the Q3 2025 average CPI-W of 317.265. The Q3 2026 average (not yet known) will be compared against it.

The Iran Oil Shock: Why Gas Prices Are Spiking

The single biggest factor pushing the 2027 COLA forecast higher is energy prices, and the single biggest factor pushing energy prices higher is the Iran conflict.

The Strait of Hormuz normally carries more than 20% of the world's daily oil supply. Since early March 2026, it has been effectively closed. On April 21, only three ships were recorded crossing the waterway, down from hundreds per day before the conflict began.

The Numbers

The International Energy Agency called this "the largest disruption in history." Physical crude prices briefly spiked near $150/barrel in spot markets, though futures have pulled back.

A fragile two-week ceasefire between the U.S. and Iran is set to expire around April 22-23. If fighting resumes and the strait stays closed, analysts warn oil could test $150 or even $200 per barrel in futures markets. That would push gas well above $5/gallon and send the CPI-W surging.

If a lasting deal reopens the strait, analysts say it could still take months for oil shipments to normalize. Either way, the March CPI-W spike of 10.9% in energy prices is already baked into the data.

Tariff Inflation: The Other Price Driver

Even before the Iran conflict, tariffs were creating upward pressure on consumer prices. The tariffs imposed in early 2026 under the International Emergency Economic Powers Act (IEEPA) raised costs on imported goods across multiple categories.

Although the Supreme Court struck down the IEEPA-based tariffs, the administration moved quickly to impose them under alternative legal authority. The net effect on consumer prices has been real: goods-sector inflation remains "sticky," meaning prices went up and haven't come back down.

For military retirees, tariff inflation works the same way as any other inflation. It pushes up the CPI-W, which pushes up the COLA. A higher COLA means a bigger raise in January 2027, but it also means you're paying more for goods right now.

What a 3.8% to 4.7% COLA Means in Dollars

Here's what the projected COLA range would add to monthly retirement checks, starting with the January 2027 payment.

VA disability compensation gets the same COLA. A veteran at 100% with no dependents currently receiving $3,938.58/month would see an increase of $150 to $185 per month.

SBP annuities also get the full COLA. REDUX retirees would receive 2.8% to 3.7% (COLA minus 1 percentage point).

COLA History: Six Years of Above-Average Raises

If the 2027 COLA comes in at 2.8% or higher, it would mark the sixth straight year that military retirees received at least a 2.5% increase. That hasn't happened since the 1988-1997 stretch.

The cumulative effect is significant. A retiree who started drawing pay in January 2022 has seen their check grow by roughly 25% in nominal terms over five years. That's the COLA doing its job: protecting purchasing power during a period of above-average inflation.

But "protecting" is the key word. COLA doesn't make you richer. It tries to keep you even. And there's growing evidence it falls short for older retirees, because the CPI-W doesn't weight healthcare costs the way retirees actually experience them.

A Higher COLA Isn't Free Money

A 3.2% COLA sounds good until you look at what's driving it. Gas at $4.09 a gallon. Grocery prices creeping up as transportation costs get passed through. Medicare Part B premiums that jumped 9.7% for 2026 (from $185 to $202.90), far outpacing the 2.8% COLA that was supposed to cover it.

COLA is a lagging indicator. You pay higher prices for months before the adjustment catches up. And the CPI-W measures spending patterns of urban wage earners, not retirees. Retirees spend a larger share of income on healthcare and housing, both of which have outpaced the CPI-W in recent years.

What You Can Control

• Review your state tax situation. If you're in a state that taxes military retirement, a higher COLA means a higher tax bill. 38 states now exempt military retirement pay from state income tax.
• Check your CRDP/CRSC elections. Your concurrent receipt payments also adjust with COLA. Make sure you're enrolled in the right program. See our CRDP vs. CRSC guide.
• Don't panic-sell TSP. A volatile market is uncomfortable, but moving to the G Fund after a drop locks in losses. The G Fund currently earns 4.375%, which barely beats a 3.2% COLA.
• Factor COLA into your retirement timing. If you're still on active duty, the COLA trap affects your first-year COLA based on which quarter you retire. A higher COLA makes the trap more costly.

FAQ

Does the 2027 COLA apply to VA disability too?

Yes. VA disability compensation, DIC (Dependency and Indemnity Compensation), and SBP annuities all receive the same COLA percentage as military retirement pay. The only exception is REDUX retirees, who get COLA minus 1%.

Could the COLA be lower than 3.8%?

Yes. The counting months are July through September, and none of them are in the books yet. But the floor is higher than it used to be: May's CPI-W already sits 3.6% above the baseline, so landing much below that would require actual price declines through the third quarter, not just slower inflation. If oil retreats hard, the high 3s become the low end rather than the middle.

Could it go above 4.7%?

Johnson herself thinks so: in June she said there is a considerable likelihood her 4.7% estimate keeps climbing as gasoline data comes in. Fuel oil is up 64.1% and gasoline up 40.7% over the 12 months through May. If those hold or rise through September, the final number pushes toward 5%. A 4.7%+ COLA would be the largest since the 8.7% of 2023.

I'm still active duty. Does this affect me?

Not directly. Active duty pay raises are set by Congress through the NDAA, not by COLA. The 2026 active duty raise was 3.8%. The 2027 raise will be determined separately. However, if you're planning to retire in 2027, the COLA will affect your retirement pay starting from your retirement date, and the quarter you retire in matters. See our COLA trap guide.

When will the next update be?

The June 2026 CPI-W lands July 14, 2026 at 8:30 a.m. Eastern. It is the last reading before the quarter that counts. After that: July data in mid-August, August data in mid-September, and the official announcement in mid-October once September's number is in.
