Retiring at 67 with $950,000 saved and Social Security paying $3,200 per month looks comfortable on paper. Run the standard numbers and you get $76,400 in gross annual income, which clears most retirement budget benchmarks. The problem is that most retirement calculators are wrong about two specific line items, and the error compounds every year you stay retired.
The core concern is whether a plan that looks fine in year one quietly develops a structural deficit by year five or seven, driven by costs that grow faster than the income supporting them.
$950,000 Saved, $76,400 in Income, and a Growing Structural Gap
- Age and status: 67-year-old single retiree, claiming Social Security at full retirement age
- Social Security income: $3,200 per month ($38,400 per year)
- Portfolio withdrawal: 4% of $950,000, producing $38,000 per year
- Total gross income: $76,400 per year
- Core risk: Healthcare and property costs are inflating faster than the income sources covering them
Where the $7,200 Gap Actually Comes From
Most retirement planning tools budget $3,000 to $4,000 per year for healthcare. That figure is outdated the moment you enroll in Medicare.
The real 2026 Medicare cost stack for a single retiree starts with Part B at $202.90 per month, a 9.7% jump from 2025 that is more than three times the size of Social Security’s 2.8% COLA for the same year. That premium increase alone ate up more than a quarter of the COLA for the average retiree. Add a Medigap Plan G policy, which averages around $220 per month at age 65 nationally, though it can run from roughly $160 in lower-cost states to over $350 in states like New York. Tack on a Part D drug plan averaging $55 per month. That puts total Medicare-related premiums at roughly $430 to $530 per month, or $5,160 to $6,360 per year. Then add the costs Medicare does not cover: dental at $50 per month, vision at $15 per month, and hearing supplements at $25 per month, for another $1,080 per year.
Total actual healthcare spending lands between $6,240 and $7,440 per year. The gap versus what most calculators assume is $2,200 to $4,400 for healthcare alone. That gap is widening: this is the third consecutive year that Medicare Part B premiums have risen faster than the Social Security COLA. Medigap Plan G premiums surged another 12% to 26% in 2026 rate filings across many states, adding further pressure on top of the Part B increase.
The second gap is property taxes. On a $350,000 home paying $4,200 per year in property taxes, assessments rising at 5% to 7% annually compound fast. Social Security’s 2026 COLA came in at 2.8%, and services inflation is running at about 3% year-over-year as of early 2026. Both rates directly outpace that adjustment. By year 10, the compounding property tax burden alone adds $3,000 to $4,000 per year beyond what the original budget assumed.
Combined, the annual shortfall reaches approximately $7,200 by year five to seven of retirement. It is not catastrophic in year one. It is a slow structural leak that turns a comfortable retirement into a stressful one.
Reserve Building Beats Withdrawal Rate Hikes for Most Retirees
Given a $950,000 portfolio and a gap that builds gradually, the strategic choices are not equally weighted.
- Adjust the withdrawal rate upward now. Pulling 4.5% to 5% closes the gap in the near term but accelerates portfolio depletion. With the 10-year Treasury currently yielding around 4.5%, a conservative bond-heavy portfolio may not generate enough return to sustain higher withdrawals over 25 to 30 years. This approach works only if expenses are genuinely temporary or if the portfolio carries a significant equity weighting.
- Build a healthcare and property tax reserve now. Redirect $500 to $600 per month from discretionary spending into a high-yield savings account or short-term Treasury ladder starting in year one. By year five, that reserve covers the gap without touching principal. This is the most structurally sound approach for someone with flexibility to run a tighter budget in early retirement.
- Downsize or relocate to reduce fixed costs. Moving to a lower property-tax jurisdiction eliminates one of the two compounding pressures entirely. States with property tax freezes or senior exemptions for homeowners over 65 can effectively cap this line item. This is the highest-impact single decision available, but it requires a willingness to move.
Option two is the right starting point for most retirees in this position. It requires neither selling a home nor taking on additional portfolio risk, and it targets directly the mechanism causing the gap.
Start With an Accurate Healthcare Budget, Then Model Property Taxes Forward
The most important immediate step is building an accurate healthcare budget using actual 2026 Medicare costs, not the placeholder figures most calculators use. The difference between $3,500 and $7,000 per year is large enough to change whether this retirement works at all.
Second, look up your county’s property tax assessment history for the past five years. If assessments have been rising at 5% or more annually, model that rate forward for 10 years against a 2.8% COLA. The math will clarify whether downsizing is a preference or a necessity.
The common mistake in this scenario is assuming the year-one budget holds. It does not. The gap is not visible yet in the early years, which is exactly why it catches retirees off guard. Plan for it before it arrives.
Editor’s note: This update reflects the confirmed 2026 Medicare Part B premium of $202.90 per month (a 9.7% increase, the third consecutive year premiums outpaced the Social Security COLA), the updated 2026 Part B annual deductible of $283, Medigap Plan G national average premiums of around $220 per month with 12% to 26% rate surges in 2026 filings, and a current 10-year Treasury yield of approximately 4.5%.
