Retiring at 65 With $1.3 Million Means Navigating an $8,400 Annual Healthcare Gap Most Plans Miss

Healthcare is the line item that quietly breaks otherwise reasonable retirement plans. Pull $52,000 a year from a $1.3 million nest egg using the standard 4% rule, and roughly $8,400 of that could disappear into healthcare costs Medicare does not cover. That leaves $43,600 for housing, food, transportation, travel, and everything else, which sits below median household spending for retirees on a national basis.

Here is the math for a single 65-year-old enrolling in Medicare at the start of 2026:

• Medicare Part B standard premium: $202.90 per month, or $2,434.80 per year
• Medigap Plan G, averaged across most states: about $215 per month, or $2,580 per year
• Part D drug coverage at a typical mid-tier plan: roughly $50 per month, or $600 per year
• Out-of-pocket costs not covered by Plan G plus dental and vision: around $2,800 per year, per Fidelity’s Retiree Healthcare Cost Estimate

That adds up to a total annual healthcare bill around $8,400. The figure is built on the 2026 CMS Part B premium fact sheet, KFF’s Medigap pricing data, and Fidelity’s annual retiree healthcare estimate.

Expect these numbers to only go higher over time. Services inflation, the bucket that includes healthcare, ran 3.4% year-over-year in March 2026 and stayed above 3.3% for months, consistently outrunning goods inflation. National healthcare personal consumption expenditures (PCE) have climbed from $3,432.2 billion in January 2025 to $3,741.3 billion in March 2026.

Why This Tension Outweighs Almost Everything Else

A retiree at 65 today is also navigating an environment where the household savings rate has slid from 6.2% in early 2024 to 4% in the first quarter of 2026. Consumer sentiment sits at 53.3, in the recessionary zone of the University of Michigan index.

Clearly, it’s important to lock down the healthcare cost structure so the $8,400 line item does not creep toward $10,000 or $12,000 within a few years. That could force a higher withdrawal rate that drains the portfolio early.

Three Moves That Could Close the Gap

1. Enroll in Medigap Plan G during your six-month guaranteed-issue window at 65. Miss it, and insurers in most states can medically underwrite or decline you later, which can push the $215 average monthly premium sharply higher or make coverage unavailable entirely. California, New York, Connecticut, and Massachusetts have stronger ongoing protections, but rules vary. Verify with your state insurance department before assuming you can switch later.
2. If you have them, spend HSA dollars on Medicare premiums tax-free. Part B, Part D, and Medigap premiums all qualify as eligible expenses. New contributions stop once you enroll in Medicare, but existing balances are fair game. Running these expenses through an HSA effectively converts pre-tax dollars into healthcare spending with zero tax drag.
3. Add a standalone dental and vision policy. Original Medicare covers neither. Plans from Anthem, Delta Dental, or Aetna typically run $30 to $60 per month combined, and they convert variable out-of-pocket exposure into a predictable line item.

The IRMAA Trap You Set Two Years in Advance

Another item to watch are income-related Medicare premium surcharges. The Income-Related Monthly Adjustment Amount (IRMAA) looks back two years, so 2024 income drives 2026 Part B surcharges. The single-filer threshold for 2026 starts at $109,000 modified adjusted gross income (MAGI). Cross it by a dollar with a lumpy Roth conversion or a large capital gain, and Part B premiums jump for the year.

The practical takeaway: Do Roth conversions before age 63, sequence withdrawals to stay under the IRMAA cliffs, and treat the $8,400 as a fixed cost to plan around rather than a surprise to absorb.
