Why Your Social Security Check Feels Smaller: Even After a COLA Increase

Each year, millions of retirees look forward to their Social Security cost-of-living adjustment (COLA). On paper, it’s meant to help benefits keep up with rising prices.

But for many retirees, the reality feels very different. Rising Medicare premiums and healthcare costs can absorb those increases. The result is a frustrating financial squeeze that can make retirement income feel stagnant, even when benefits technically go up.

COLA Increases Often Trail Real Living Costs

Social Security’s annual cost-of-living adjustment is based on a specific inflation index that doesn’t always reflect how retirees actually spend money. Healthcare, housing, and insurance have often risen faster than the COLA. This gap can leave retirees feeling like their income isn’t keeping pace with reality. Even modest differences can compound over time, gradually reducing purchasing power despite regular benefit increases.

Caroline Rasker, Registered Social Security Analyst at Clarity Financial Services, explained, “When Social Security increases are modest, a good chunk (and sometimes nearly all) of that bump can get eaten up by higher Medicare Part B premiums. So even though benefits technically go up, what you actually see in your check might barely change.

There is a built-in protection – often called the “do no harm” (hold harmless) provision. This rule keeps most people already receiving benefits from seeing their Social Security checks go down just because Medicare premiums rise. In other words, your net benefit can’t drop due to Part B increases. That said, it doesn’t apply to everyone; higher-income retirees, new enrollees, and those paying IRMAA can still feel the full impact.”

Medicare Part B Premiums Are Rising Faster Than Social Security Benefits

Medicare Part B premiums have steadily increased over the years, sometimes absorbing a significant portion of Social Security raises. When premiums rise faster than COLAs, retirees may see little net improvement in their monthly income. For households already on tight budgets, even small premium increases can force difficult tradeoffs. Understanding how healthcare costs interact with benefit increases is critical for building a sustainable retirement income plan.

For example, in 1970, the average social security check was $118.03, and Medicare Part B was $4. Which means about 3% of the retiree's check was going to Medicare Part B.

In 2025, the average Social Security check was $1,976, and the cost of Medicare Part B was $185. Meaning that today, about 9% of a retiree's check is going to Medicare Part B.

IRMAA Surcharges Can Trigger Sudden Additional Costs

Higher-income retirees may face Income-Related Monthly Adjustment Amount (IRMAA) surcharges that significantly increase Medicare premiums. These surcharges are based on income from two years prior, meaning that a single large withdrawal, asset sale, or Roth conversion can unexpectedly raise healthcare costs later. Crossing an income threshold can trigger hundreds or thousands of dollars in additional annual premiums, effectively reducing available retirement income without warning.

When asked to optimize withdrawals in retirement, Jared Stoltz, VP of Insurance Sales at Diversified Insurance Brokers, Inc. said, “The key is managing taxable income in retirement. Strategies like spreading out withdrawals, using Roth conversions earlier in retirement, and being mindful of large one-time income events, such as capital gains or IRA distributions, can help keep income below IRMAA thresholds. Even small adjustments can prevent crossing into a higher surcharge bracket.”

Out-of-Pocket Healthcare Costs Keep Climbing

Even with Medicare coverage, retirees remain responsible for deductibles, copays, coinsurance, and services not fully covered. Dental, vision, hearing care, and specialized treatments can create substantial ongoing expenses. As healthcare inflation continues to outpace general inflation, these out-of-pocket costs can quietly erode retirement budgets. Many retirees underestimate how much they will spend annually on medical needs, leaving less room for discretionary spending.

Prescription Drug Costs Can Be Highly Variable

Prescription expenses can fluctuate widely depending on coverage changes, new medications, or evolving health conditions. Even retirees with Part D coverage or Medicare Advantage plans may face higher-than-expected drug costs due to formulary changes or coverage gaps. A single expensive medication can dramatically increase monthly spending. Planning for variability in prescription costs can help retirees avoid financial surprises that strain retirement income.

Medicare Advantage Plan Changes Create Budget Uncertainty

Medicare Advantage plans can adjust premiums, provider networks, and coverage benefits from year to year. Retirees who fail to review plan updates during open enrollment may discover higher costs or reduced access to preferred doctors. Switching plans can also introduce new out-of-pocket limits and service restrictions. This evolving landscape makes it harder to predict long-term healthcare spending, adding uncertainty to retirement income planning.

Required Minimum Distributions Can Increase Medicare Premiums

Once retirees begin taking Required Minimum Distributions (RMDs), their taxable income may rise significantly. Higher income can push retirees into IRMAA brackets, increasing Medicare premiums. Strategic withdrawal planning before RMD age may help retirees manage income levels and avoid unnecessary premium increases.

Long-Term Care Isn’t Covered by Medicare

Many retirees mistakenly assume Medicare will cover extended nursing home stays or in-home custodial care. In reality, Medicare coverage for long-term care is limited and typically short-term. If long-term care becomes necessary, retirees may need to rely on savings, insurance, or Medicaid eligibility. These potential costs represent one of the largest financial risks in retirement and can significantly impact income sustainability.

Healthcare Inflation Often Outpaces General Inflation

Medical costs have historically risen faster than overall consumer prices. This trend means retirement income strategies based solely on general inflation assumptions may fall short. Even well-planned budgets can become strained as healthcare expenses consume a larger share of income over time. Factoring higher healthcare inflation into retirement projections can help retirees prepare for future financial pressure.

Survivor Income May Not Cover Ongoing Medical Needs

When one spouse dies, household income often declines because the surviving spouse typically keeps only the higher Social Security benefit. However, healthcare costs may not fall proportionally. Fixed medical expenses, insurance premiums, and long-term care needs can remain high. This mismatch can leave surviving spouses financially vulnerable, making coordinated planning essential for long-term stability.

Withdrawal Strategies May Need Adjustment Over Time

As healthcare costs rise, retirees may need to rethink how they generate income from savings. Fixed withdrawal strategies that worked early in retirement may become less sustainable. Adjusting spending, rebalancing investments, or exploring additional income sources can help preserve long-term financial security. Regular reviews of retirement income plans are critical as expenses evolve.
