Retirement Calculator for a 65 Year Old
At 65, Medicare enrollment opens, your HSA contribution window closes, and you're 2 years from full Social Security. The decisions you make in this single year shape the next decade of retirement income.

Where you should be at 65
Fidelity recommends 10 times your salary by 67. At 65, that puts the on-track target at roughly 9.4 times your salary. On a $75,000 income, that's about $705,000. On a $100,000 income, the target is closer to $940,000.
The actual numbers tell a different story. The average 401(k) balance for the 65 and older group is $299,442. The median is $95,425 (Vanguard, How America Saves 2025). Half of all 65 year olds with a 401(k) have less than $95,425 in it. The average is roughly 3 times the median because a small number of high-balance accounts pull the average up.
If you're behind the target, the most useful thing you can do at 65 is plan a withdrawal sequence and Social Security claiming strategy that stretches what you have. Two years of delayed retirement credits are still on the table.

Retirement strategies at 65
Enroll in Medicare during your initial 7 month window
Your initial enrollment period covers the 3 months before your 65th birthday month, the birthday month, and the 3 months after. Missing it can mean a Part B late enrollment penalty of 10% of the standard premium for each full year you delayed, added to your premium for life. There are valid exceptions if you're covered by a current employer's group plan. The penalty is real, so verify your situation against Medicare.gov well before your birthday month.
Stop HSA contributions before Medicare starts
Once you enroll in Medicare, HSA contributions must stop. Existing HSA balances stay yours. You can use them tax-free for qualified medical expenses, including Medicare Part B and Part D premiums (Medigap premiums are not qualified). At 65, the 20% penalty for non-medical withdrawals also disappears, so HSA dollars become flexible retirement money taxed only as ordinary income. If you have a large HSA, treat it as a tax-efficient bucket for future healthcare costs first.
Decide what to do with employer health coverage
If you're still working at 65 with employer coverage, you have a real decision: stay on the employer plan and delay Medicare without penalty, or enroll in Medicare and coordinate the two. The math depends on plan size, premiums, and prescription costs. Most people working at small employers (under 20 employees) need to enroll in Medicare Part A and Part B at 65 regardless, since Medicare becomes primary. Larger employers usually let you delay. Confirm before your birthday.
Two more years of delayed Social Security credits are still available
If you claim at 65, you receive 86.7% of your full benefit. Waiting to your full retirement age of 67 gives you 100%. Waiting all the way to 70 gives you 124% (SSA). The break-even age between claiming at 65 and at 70 typically lands in the early 80s. If you're in good health and have savings to bridge the gap, delaying produces more lifetime income for most retirees.
Begin a Roth conversion ladder before RMDs
RMDs begin at 73. Between now and then you have an 8 year window to convert traditional 401(k) and IRA balances to Roth at potentially lower marginal tax rates, especially in years before you claim Social Security. Each conversion reduces future RMD amounts and the share of your Social Security that gets taxed. The right amount to convert each year depends on the top of your current tax bracket. Work with a CPA or use our retirement income calculator to model the tradeoff.
