How Do You Plan for Medicare? What Early Retirees Need to Know Before 65

Why Is the Pre-Medicare Gap So Expensive?

If you retire at 60, you have five years without employer-sponsored health insurance and before Medicare kicks in. ACA marketplace plans for a couple in their early 60s can run $1,800-2,200 per month before subsidies — that's $21,600-26,400 per year.

But here's what most people miss: ACA premium tax credits are based on your modified adjusted gross income (MAGI). If you can keep your MAGI below 400% of the Federal Poverty Level (about $79,760 for a couple in 2025), you qualify for substantial subsidies that can cut premiums by 50-70%.

This is where withdrawal sequencing becomes critical. Drawing from Roth accounts (not taxable income) or taxable accounts at favorable capital gains rates can keep your MAGI low enough to qualify for credits.

What Are the Four Parts of Medicare and What Do They Cost?

Part A (hospital insurance) is premium-free for most people who paid Medicare taxes for 10+ years. Part B (medical insurance) has a standard premium of about $185/month in 2025, plus IRMAA surcharges for higher earners. Part D covers prescription drugs. Medicare Advantage (Part C) bundles A, B, and often D into one plan.

Medigap (Medicare Supplement) policies fill the gaps in Original Medicare — copays, coinsurance, deductibles. The best time to enroll is during your initial enrollment period (3 months before to 3 months after turning 65), when insurers must accept you regardless of health status.

Total out-of-pocket for Medicare in retirement — including premiums, copays, and services not covered — averages about $6,500-8,000 per person per year. That's significantly less than pre-65 coverage, which is why the gap years are so important to plan for.

How Does Income Management Affect Your Healthcare Costs?

Your income in retirement directly affects both ACA premiums (before 65) and Medicare premiums (after 65). The analysis engine models this interaction year by year.

Before 65: Keep MAGI below the ACA subsidy cliff. Strategic Roth conversions in years when you're below the cliff can provide tax-free income later without affecting future premiums.

After 65: IRMAA thresholds determine Medicare surcharges. The 2-year lookback means a large Roth conversion at 63 could increase your Medicare premiums at 65. The analysis projects these interactions to help identify the optimal balance.
