Guyton-Klinger decision rules · Also called: Guyton-Klinger
A spending method that starts from an inflation-adjusted amount and cuts or raises it by a set percentage whenever the current withdrawal rate drifts outside upper and lower limits.
When the withdrawal rate rises too far above its starting level, spending is cut (the capital preservation rule); when it falls far enough below, spending is raised (the prosperity rule). The method supports a higher starting withdrawal in exchange for accepting occasional cuts.
