Claiming timing

Claiming earlier provides income sooner at a reduced monthly amount. Delaying can increase the monthly benefit up to the applicable maximum delay age. Which is better depends on expected longevity, other income, retirement timing, spousal and survivor benefits, taxes, and what the rest of the plan is doing in those years.

For a married couple there are effectively two decisions, and the survivor benefit means the higher earner's claiming age can matter for as long as either spouse is alive.

Retiring before 65

Leaving work before Medicare begins means the plan carries health coverage on its own. Options may include a spouse's employer plan, COBRA, Affordable Care Act coverage, retiree coverage, or other insurance.

This is one place where the withdrawal plan and the healthcare plan are the same plan: the taxable income a household reports can affect the cost of marketplace coverage, which can make a low-income bridge year worth more than it first appears.

Enrollment windows

Medicare enrollment timing depends on age, current employer coverage, and individual circumstances, and missing an applicable window can create coverage gaps or penalties in some cases. Rules differ depending on whether you or a spouse are still working and what coverage is in place, so review the current rules at Medicare.gov before retirement or age 65.

Income-related premium costs

Certain higher-income beneficiaries pay income-related monthly adjustment amounts for Part B and Part D, generally based on modified adjusted gross income from an earlier tax year. That lookback is why a Roth conversion, large IRA withdrawal, or stock sale is also a Medicare decision. Verify current thresholds for the relevant year.

Healthcare as an ongoing retirement expense

Healthcare belongs in the spending plan as a line that changes over time rather than one estimate. Premiums, deductibles, out-of-pocket costs, dental and vision, and long-term-care considerations all evolve, and the pre-65 period deserves its own assumptions.
