Kiplinger Puts Baseline Retirement Costs at $5,624-$6,694 a Month, Testing $10,000 Budgets

Q: Why might your high income today secretly trigger massive Medicare surcharges years after you stop working?

Your high income today can raise your Medicare premiums years after retirement because Medicare uses a two-year lookback and applies income-based surcharges known as IRMAA. That means your 2026 Medicare Part B and Part D premiums are based on your 2024 modified adjusted gross income, not what you earn in 2026. A big salary, bonus, stock sale, Roth conversion, large IRA withdrawal, or capital gain while you are still working can push you over an IRMAA threshold and trigger higher premiums later, even if your income drops sharply after you stop working. The effect can be substantial. For 2026, IRMAA starts above $109,000 for single filers and $218,000 for married couples filing jointly. Standard Part B is $202.90 a month, but high earners can pay as much as $689.90 per person, plus Part D surcharges of up to $91 a month. Because the system works like a cliff, going over a threshold by even $1 can raise premiums for the full year. This is one reason a seemingly comfortable retirement income can feel tighter than expected: healthcare costs are not just about doctor bills, but also about tax-driven Medicare premiums set years earlier. There is one important safeguard. If your income fell because of a qualifying life-changing event such as retirement, you may ask Social Security to reduce the surcharge by filing Form SSA-44. Careful timing of Roth conversions, asset sales, and withdrawals can also help limit future IRMAA costs.

$10,000 a month leaves a sizable cushion against Kiplinger’s national baseline, which pegs typical retiree spending at $5,624.37 to $6,694.43 before location, health and lifestyle push costs higher.
Housing is the biggest modeled expense at $2,669.92 a month, followed by healthcare at $960.89 to $1,538.89 and transportation at $1,037.73 to $1,456.01.
Healthcare remains a major wildcard: Fidelity estimates a 65-year-old retiree will face $172,500 in lifetime out-of-pocket medical costs, excluding long-term care or emergency-room visits.
The analysis contrasts with Schroders’ 2026 survey, where not-yet-retired Americans said they would be comfortable on $5,094 a month, suggesting many may underestimate retirement costs.
