Retirement cash guide
The cash you keep safe should work as hard as you did
Reviewed July 2026
Money you'll spend in the next few years doesn't belong in the stock market. But "safe" shouldn't mean "earning almost nothing" — and at most big banks, that's exactly what checking and standard savings pay. Moving idle cash into the right mix of high-yield savings and CDs is the easiest raise you can give yourself in retirement.
The two tools, in one minute
- High-yield savings (HYSA): full access anytime, rate can change. Right for the emergency fund and anything you might need on short notice.
- Certificates of deposit (CDs): the rate is locked for the term, but so is the money (early withdrawal costs interest). Right for cash with a known date — next year's property taxes, the big trip, living expenses for years two and three.
At FDIC-member banks, both are insured up to $250,000 per depositor, per bank, per ownership category — credit unions carry the equivalent NCUA coverage. That insurance is the whole point: these are the accounts where losing money isn't on the menu. Just confirm the institution is actually a member before you open; some fintech "cash accounts" aren't.
The CD ladder, explained with $40,000
Split the money into four $10,000 CDs: one each at 6, 12, 18, and 24 months. Every six months a CD matures — if you need the cash, take it; if not, roll it into a new 24-month CD at whatever rates are then. You get most of the yield of long CDs with money coming available twice a year.
Three mistakes we see constantly
- Loyalty to the big bank. The branch is convenient; the 0.01% savings rate is not. Online banks routinely pay fifty times more, with the same FDIC insurance.
- Letting CDs auto-renew. Banks count on it. The renewal rate is often far worse than what the same bank offers new money. Calendar the maturity date.
- Chasing yield into things that aren't cash. If it isn't FDIC- or NCUA-insured, it's an investment, not savings — fine on purpose, dangerous by accident. Watch for "CD-like" pitches that are really annuities.
