If your Social Security benefit rises in 2026, it can feel like a welcome breath of room in your budget. The catch is that healthcare costs don’t wait politely for inflation to cooperate. A 2.8% COLA can help, but what matters is how much of that increase you actually keep after premiums, deductibles, and prescription costs. The good news is you can estimate the impact in a few minutes and make smarter choices before surprises hit. Here’s how to tell whether the bump will cover your healthcare reality this year.
What the Adjustment Really Covers
Social Security sets the annual increase using the CPI-W, comparing the third quarter of one year to the third quarter of the next. That means the change reflects broad inflation patterns, not the specific mix of expenses retirees face. Healthcare spending can rise for reasons that have nothing to do with general inflation, like plan design changes or higher utilization. Your “real” inflation rate may be very different from the national average. Start by treating the increase as a baseline, not a guarantee.
Medicare Part B Premiums Can Take the First Bite
The fastest way the 2.8% COLA gets absorbed is through Medicare Part B premiums, because many people have them deducted from their monthly benefit. For 2026, the standard Part B premium is $202.90 per month, up from $185.00 in 2025. If your benefit is modest, that premium jump can eat a meaningful share of your raise before you notice the extra money. Look at your December deposit and your January deposit to see the net change after deductions. If you’re on direct billing instead of deduction, plan for a higher premium bill.
Deductibles and Coinsurance Still Drive What You Pay
Even if your monthly premium feels manageable, the 2.8% COLA may not fully cover higher out-of-pocket costs when you actually use care. For 2026, the Medicare Part B deductible is $283, up from $257 in 2025. Part B also typically involves coinsurance after you meet the deductible, and there’s no universal annual out-of-pocket maximum in Original Medicare. That means one year of heavier medical needs can overwhelm a small monthly increase. If you budget tightly, plan for “lumpy” costs like imaging, outpatient procedures, or frequent specialist visits. A simple move is to set aside a small monthly amount specifically for deductibles and coinsurance.
Prescription Drugs Bring Relief for Some, Pressure for Others
If you take expensive medications, the 2.8% COLA might feel more helpful in 2026 because Part D has a yearly out-of-pocket cap of $2,100. Still, plans can have deductibles, and Medicare notes no Part D plan can set a deductible higher than $615 in 2026. Your costs also depend on your drug’s tier, your pharmacy network, and whether your plan uses prior authorization. One practical tool is the Medicare Prescription Payment Plan, which lets you spread out-of-pocket drug costs into monthly payments instead of paying big amounts at the pharmacy counter. If you’re close to the cap, smoothing can make cash flow feel far less stressful.
Higher Income Can Trigger Surcharges You Didn’t Budget For
For some households, the 2.8% COLA isn’t the main story—IRMAA is. IRMAA is a surcharge added to Medicare Part B and Part D for higher-income beneficiaries, and it’s based on your modified adjusted gross income from two years earlier. SSA’s Form SSA-44 materials reflect that if your MAGI is below $109,000 (single) or $218,000 (married filing jointly), you generally won’t owe an IRMAA amount for 2026. If you crossed a threshold because of a Roth conversion, a one-time capital gain, or selling property, your Medicare costs can jump even if your day-to-day spending didn’t. If you had a life-changing event like retirement, you may be able to appeal using SSA-44 with documentation.
“Enough” Depends on Your Personal Healthcare Inflation
The 2.8% COLA is a broad adjustment, but your healthcare costs are personal and lopsided. If you have frequent appointments, pricey prescriptions, or ongoing therapies, you’ll feel increases more sharply than someone who rarely uses care. Plan changes can also move costs around, even when the overall premium doesn’t look dramatic. And because the COLA is tied to CPI-W methodology, it won’t perfectly track the categories that drive retiree budgets. The best way to judge “enough” is to compare your 2025 healthcare spending to your projected 2026 costs line by line.
Your Coverage Choices Can Change the Math
Many people set Medicare and forget it, then wonder why costs feel unpredictable. Open enrollment gives you a chance to compare premiums, drug coverage, provider networks, and out-of-pocket protections based on how you actually used care last year. If you had surprise bills, that’s a signal to review your setup, not just your spending habits. A plan with a slightly higher premium can sometimes lower total costs if it reduces coinsurance exposure or improves drug coverage. The goal is to pay for predictability when unpredictability is what’s draining you.
Quick Moves That Help You Keep More of the Increase
First, verify how your Part B premium is paid and whether it’s deducted from your benefit, because that’s often the biggest “silent offset.” Next, if prescriptions drive your budget, consider using the Medicare Prescription Payment Plan to spread costs across the year. If your income is limited, check whether you qualify for Extra Help, which can reduce Part D premiums, deductibles, and copays. And if you got hit with an income-related surcharge after your income dropped, look into an IRMAA appeal through SSA-44.
Look at Your Net, Not the Headline
The 2.8% COLA is real money, but the question is what lands in your pocket after Medicare costs come out. For many retirees, Part B premium increases alone can shrink the visible gain, especially when premiums are deducted automatically. If you have high drug spending, the Part D cap and payment-smoothing options can help, but you still need to verify your plan details. The easiest win is a simple annual review: premiums, deductibles, prescriptions, and any surcharges based on income. Once you measure your net change, you’ll know whether you need to adjust coverage, budget, or both.
