The Amer­i­can Insti­tute for Eco­nom­ic Research (AIER) has released a new study exam­in­ing retire­ment draw-down strate­gies, mov­ing beyond the stan­dard 4% Rule to take into account the full range of finan­cial risks and oppor­tu­ni­ties that retirees will like­ly face. The AIER analy­sis finds that no sin­gle rule works for every­one; that the ear­ly retire­ment years mat­ter most in suc­cess­ful retire­ment finance; and that a flex­i­ble draw-down strat­e­gy leads to bet­ter retire­ment out­comes.
