Emergency Fund in Retirement: Your Cash Bucket

It keeps a market decline or a large bill from turning into a forced sale. The danger is specific: selling shares while they are down locks in the loss, and those shares are not there for the recovery. Early in retirement, when the portfolio is largest and has the longest to run, this sequence-of-returns risk does the most damage. Our asset allocation guide shows how two retirees with identical average returns can end 20 years apart by millions, simply because of the order of returns.

A cash reserve breaks that chain. With two years of withdrawals in cash, you can go through most bear markets without selling a share of stock. Historically, many declines have recovered within that window, though not all; that is why the next bucket in a well-built retirement portfolio is several more years of high-quality bonds.

More than most people expect, which is the main reason retirees need an irregular-expense reserve. Original Medicare does not cover most dental care, hearing aids, routine eye exams or eyeglasses, and it does not cover long-term care (Medicare.gov). A set of hearing aids, a dental implant or new glasses can each cost thousands of dollars in a single year.

Then there are the routine costs. In 2026 the standard Part B premium is $202.90 a month and the Part B deductible is $283 (CMS). Higher-income retirees pay more through IRMAA surcharges, which are based on your tax return from two years earlier, so a large IRA withdrawal to refill cash can raise your premiums later. Part D prescription drug costs are capped at $2,100 out of pocket in 2026 (Medicare.gov).

Plan for these in your regular budget where you can, and let the reserve absorb the surprises. Our healthcare cost estimator projects lifetime costs, the Medicare and IRMAA guide covers the surcharges, and the long-term care guide covers the largest risk, which no cash reserve is sized to handle.

Mind the FDIC limit. Deposit insurance covers $250,000 per depositor, per insured bank, for each ownership category, such as single, joint, retirement and trust accounts (FDIC). A couple holding $400,000 in one joint account at one bank is fully covered, because a joint account is insured up to $250,000 per co-owner; the same $400,000 in one person's single account is not. Spread larger balances across banks or ownership categories, or hold them in Treasury bills. Our CD and Treasury ladder calculator shows what a ladder of either would pay, and what the Treasury version saves in state tax.

Brokerage cash is different. SIPC protects the custody of cash and securities at a failed brokerage up to $500,000, including $250,000 of cash, but it does not protect against a decline in value (SIPC). Treasury bills and government money market funds held at a major custodian are a common home for larger reserves.

Which account? Many retirees keep the irregular-expense reserve in a taxable savings account they can reach instantly, and the spending reserve inside the IRA as a Treasury money market fund. That way next year's withdrawal, including any required minimum distribution, is already sitting in cash.

Help for family deserves its own line in the plan. An adult child's job loss or a grandchild's tuition is a real need, but treating it as an emergency tends to drain the reserve that protects your own income. Decide in advance how much you are willing to give or lend, and from which account. Our guide to gifting to children and grandchildren covers the tax side.

Watch the tax side. Refilling from a traditional IRA adds to taxable income, which can push you into a higher bracket or an IRMAA tier two years later. Once required minimum distributions start (at 73, or 75 if you were born in 1960 or later), the RMD is a natural refill source because you must take it anyway. If you give to charity, qualified charitable distributions from an IRA can satisfy part of the RMD without adding to income; see our QCD guide.
