For most of your working life, emergency-fund advice probably sounded straightforward: keep enough cash available to survive a few months without a paycheck. Then you retire, the paycheck disappears permanently, and suddenly that familiar rule does not fit quite as neatly. Social Security, pensions, retirement-account withdrawals, and other income may continue arriving even when the furnace breaks or the car needs a $3,000 repair. That doesn’t eliminate the need for cash reserves, but it does change what those reserves are supposed to accomplish. A retirement emergency fund should be designed around the risks you actually face after leaving work rather than a savings rule created primarily for working households.
