How Much Do I Need to Retire?

To determine retirement savings needs, multiply expected annual spending by 25, based on the 4% rule, to sustain withdrawals for 30 years. Factors like early retirement, healthcare costs, and legacy plans increase savings needs, while pensions, homeownership, or lower living costs reduce them. Use realistic assumptions for returns, inflation, and longevity, and consider professional advice to manage taxes, withdrawal risks, and Social Security timing.
