This calculator tells you how much you will be withdrawing from your retirement accounts, how much you will earn from them in total, and what your total income tax and penalties will be given those amounts. It then shows you these figures in year-by-year tables. It helps you to answer key questions related to achieving your retirement goals, and considers your age, expected length of retirement, estimated living expenses, Social Security benefits, taxable vs. tax-advantaged savings, inflation, and more.
