Understanding the 2025 COLA Increase and What Changed for 2026

Social Security retirees received a 2.5% cost-of-living adjustment in 2025, helping offset inflation’s impact on fixed incomes. However, the news for 2026 presents a more complex picture. While estimates suggest a larger benefits bump of around 2.7% next year, the actual take-home gain may be substantially smaller due to rising Medicare premiums—a gap that challenges the optimism surrounding the increase.

The 2025 COLA increase provided modest relief, but seniors quickly discovered that much of their raise was absorbed by climbing healthcare costs. This year’s experience offers important context for understanding why a seemingly “bigger” 2026 payment might deliver less financial improvement than expected.

Why This Year’s Medicare Changes Matter More Than Your 2025 COLA Increase

The critical issue isn’t just about the size of the benefit boost—it’s about what gets deducted from it. In 2025, Medicare Part B premiums rose by $10.30 per month, which meant someone receiving a $2,000 monthly benefit gained only about $39.70 after the deduction, despite receiving a $50 monthly raise from their 2.5% COLA increase.

For 2026, Medicare Board of Trustees projections signal a dramatic shift: Part B premiums are expected to jump $21.50 per month—more than double the 2025 increase. This represents one of the steepest year-over-year premium hikes in Medicare’s history. The consequence is sobering: while a 2.7% benefits adjustment sounds like progress compared to the 2025 COLA increase, a senior with that same $2,000 monthly benefit would see only $32.50 in actual spending power, despite a nominal $54 monthly raise.

When a Bigger Increase Doesn’t Mean Better Finances

The counterintuitive reality is that a larger 2025 COLA increase compared to previous years, now followed by an even bigger 2026 adjustment, actually signals ongoing inflation pressures. Cost-of-living adjustments are calculated directly from inflation metrics, so larger percentage increases reflect higher prices for goods, services, and healthcare—outcomes that typically hurt retirees living on fixed incomes.

Many seniors have conservative investment portfolios designed for retirement stability, meaning their returns rarely keep pace with significant inflation. Combined with Medicare premium spikes, the real purchasing power gain vanishes on paper, leaving retirees struggling to maintain their standard of living despite receiving what appears to be a boost.

The 2026 picture underscores a fundamental challenge: the 2025 COLA increase provided only modest relief, and next year’s larger adjustment may prove similarly disappointing once healthcare costs are factored in.
