The amount you need depends on your expected annual expenses, other income sources (Social Security, pensions), and how long you expect to be retired. A common guideline is the 4% rule: you need 25 times your annual expenses minus guaranteed income saved. For example, if you need $60,000 per year beyond Social Security and pensions, you would need approximately $1.5 million in retirement savings.
