Uncomfortable Math: A $4,200-a-Month Pension With No COLA Buys $2,300 Worth of Living by Age 85
A pension that looked generous at 65 can quietly turn into something far less comfortable two decades later, and most retirees never see it happening until the damage is done. The culprit is not a bad investment or a market…

Picture a 65-year-old walking into retirement with a $4,200 monthly pension check, no Social Security haircut, and a paid-off house. On paper, it looks like a soft landing. The problem shows up 20 years later, when that same $4,200 buys roughly $2,300 worth of the life it used to. The check number holds flat while everything it pays for climbs.
This scenario is more common than most retirees realize. Corporate and public pensions without cost-of-living adjustments (COLAs) are the norm outside of federal service and a handful of state systems. If you worked 30 years at a private employer with a defined-benefit plan, odds are high your monthly benefit is fixed for life.
Why a Fixed Check Quietly Loses the Race
Inflation is not a headline event for a pensioner. It is a slow leak. The Consumer Price Index reached 334.1 in August 2026, up from 324.2 in September 2025. Headline PCE inflation was running at 3.7% year over year in July 2026, with services at 4% and energy at 15%. Retirees spend disproportionately on services (healthcare, insurance, home maintenance) and energy (utilities, gasoline), the two categories running hottest.
Contrast that with a Social Security recipient. The 2027 COLA is tracking toward 3.3%. A $2,000 Social Security check grows automatically. A $4,200 pension check does not. Over a 20-year retirement, that gap compounds into a different lifestyle.
Math Most Retirees Skip
The average U.S. household spent $78,535 in 2024, up from $77,280 in 2023. That is roughly $6,500 a month for a working-age household, with retirees typically landing 15% to 25% below that.
A $4,200 pension covers a retiree comfortably at 65. By 75, at 3% average inflation, it feels like a $3,100 check. By 85, it feels like the $2,300 in the headline. The bills did not shrink. Groceries, Medicare Part B premiums, homeowners insurance, and property taxes all march upward. The pension does not march with them.
This is why 57% of pre-retirees named inflation as their top retirement obstacle in 2025, and why 51% of adults think it is somewhat or very likely they will outlive their savings. With a no-COLA pension, the purchasing power runs out even though the check keeps arriving.
Lump Sum vs. Monthly: Run the 6% Test
If your employer offers a lump-sum buyout, do the arithmetic before defaulting to the monthly check. Money expert Wes Moss uses what he calls the 6% test: divide the annual pension income by the lump sum offered. On a $58,000 lump sum versus $411 a month, the implied rate was 8.5%, strong enough that he leaned toward the monthly payment. Below roughly 6%, the lump sum usually wins because you can invest it in assets that grow with inflation.
For a $4,200 monthly pension ($50,400 a year), the buyout would need to exceed roughly $840,000 to justify keeping the annuity. Anything meaningfully above that number, and taking the lump sum into a diversified portfolio becomes the more defensible path, precisely because it can grow while the pension cannot.
A retired pilot wrote to Clark Howard describing how his airline declared bankruptcy six years after retirement, and pensions were turned over to the Pension Benefit Guaranty Corporation for pennies on the dollar. Colleagues who took the partial lump sum kept more of their money. PBGC caps bite hardest on higher earners.
Two Paths That Actually Work
- Keep the pension, but build an inflation sleeve. If your outside savings can fund a separate bucket earmarked for the inflation gap, you can invest that bucket in equities, I Bonds, or TIPS specifically to offset the shrinking check. For every $1,000 of monthly pension, set aside roughly $50,000 to $75,000 in growth assets to defend purchasing power over a 20-year horizon.
- Delay Social Security to age 70. This is the single most powerful inflation hedge available to a no-COLA pensioner. Every year you delay past full retirement age adds 8% to your benefit, and the resulting check is indexed to inflation for life. Pairing a fixed pension with a maximized, COLA-adjusted Social Security benefit is the cleanest structural fix for this problem.
What to Do This Month
Pull your pension summary and confirm in writing whether any COLA exists, even a capped one. Then pull your Social Security statement and model claiming at 67 versus 70 (we condensed that whole decision onto a single page in a free guide here). The delta between those two claiming ages is often larger than any investment decision you will make in retirement. The common mistake is treating the $4,200 check as permanent income when it is nominal income. Real income is what it buys, and that number falls every year you do nothing about it.
