The standard Medicare Part B premium climbed to $202.90 a month in 2026, up from $185 in 2025. Add a Part D drug plan and a Medigap supplement, and many retirees are spending thousands of dollars every year simply to maintain coverage. Unlike a mortgage, this bill never gets paid off. The question is how much capital it takes to generate enough income to cover Medicare costs indefinitely.
The Number to Cover
A reasonable middle-ground target for an annual Medicare stack (Part B, Part D, and a Medigap supplement) is roughly $6,000 a year, or $500 a month. Lighter coverage runs $3,000 to $4,000. Higher earners pulled into IRMAA surcharges can push past $8,000 to $12,000. Use the $6,000 figure as the working baseline. The math scales linearly if your stack is different.
The core equation never changes: annual cost divided by portfolio yield equals capital required.
Conservative Tier: 3.5% to 4.5%
This is the dividend growth and broad-market yield zone, with the 10-year Treasury currently anchoring it at 4.5%. Think dividend aristocrats, total-market index funds with rising payouts, investment-grade corporate bonds, and intermediate Treasuries. At 3.5%, covering $6,000 requires about $171,429. At 4%, the number drops to $150,000.
You need the most capital here, but the income stream typically grows. A dividend growth allocation that raises its distribution 7% a year doubles the payout in roughly a decade. That matters when Social Security’s 2026 cost of living adjustment is 2.8%, and healthcare inflation routinely runs faster than the headline CPI series, which climbed from 308.417 in January 2024 to 335.123 in May 2026.
Moderate Tier: 5% to 7%
This is the high-yield equity and hybrid range: covered call ETFs, preferred shares, equity REITs, midstream energy partnerships, and high-dividend value funds. At 5%, you need $120,000 to throw off $6,000. At 7%, the requirement falls to roughly $85,714.
The trade is real. Covered call strategies cap upside in strong markets. Preferreds behave more like long-duration bonds than equities. REITs carry interest rate sensitivity, which matters in an environment where the Fed funds upper bound has fallen from 4.5% in September 2025 to 3.8% today. Income tends to stay flat rather than compound.
Aggressive Tier: 8% to 12%
Business development companies, mortgage REITs, leveraged covered-call funds, and high-yield bond funds sit here. At a 10% yield, only $60,000 of capital is needed to generate the $6,000 required. On paper, this is the most capital-efficient approach we present.
It is also the most fragile. Distributions can be cut during credit cycles. Principal often erodes over multi-year holding periods. The portfolio may pay your Medicare bill while quietly losing value, which means you are essentially spending the asset rather than living off its growth.
What Most Retirees Miss
A 10% yield with no growth keeps paying the same $6,000 year after year. The problem is that Medicare premiums rarely stand still. A 4% yield growing 7% annually eventually produces more income than a static 10% yield while also preserving more purchasing power. The higher yield solves today’s problem. The growing income stream is often better suited to solving next decade’s problem.
There is also a tax wrinkle worth pricing in. Successful Roth conversions, large capital gains, and big withdrawals can trigger IRMAA surcharges, with the next bracket starting at modified adjusted gross income above $109,000 for individuals or $218,000 for joint filers. Generating more income can paradoxically raise the bill you are trying to cover.
The Psychological Win
Covering Medicare with portfolio income does more than improve cash flow. It removes one of retirement’s most predictable monthly bills from the household budget. Once retirees know that healthcare premiums are funded by their investments, Social Security and other income sources become available for housing, travel, charitable giving, or everyday living expenses.
Three Moves Worth Making
- Add up your actual Medicare costs (Part B, Part D, Medigap, any IRMAA), then divide by 5% and 7% to bracket the realistic capital range. A national 12-month CD averaging 1.7% will not get you there.
- Compare a 10-year total return of a 3.5% dividend growth fund against a 10% high-yield fund. Look at distributions plus principal, not yield alone.
- Pick the next recurring bill (utilities, property taxes, insurance) and repeat the exercise. Retirement income gets easier when it is built one expense at a time.
