What is the marginal withdrawal rate?

The marginal withdrawal rate refers to the percentage of an individual's or household's income or assets that is drawn down for consumption or expenses at a specific point in time, particularly in the context of retirement or investment accounts. It helps assess how much of their savings is being used to support living expenses, influencing long-term financial sustainability. A higher marginal withdrawal rate may indicate a risk of depleting resources too quickly, while a lower rate suggests more sustainable financial health. Understanding this rate is crucial for effective financial planning and retirement strategies.
