Retirement spending

Overview
This article is the entry point for the topic Retirement Spending. Its purpose is to provide a high level summary of the information contained in the associated articles.

Many studies on retirement spending start with an assumed total savings at retirement and then estimate the spending that might be allowable each year afterwards. Such studies are often especially concerned with estimating the maximum spending that won’t lead to premature depletion of personal savings, known as the Safe Withdrawal Rate. These models treat the Total Savings at Retirement as the key independent variable. The spending for each year in retirement is adjusted so that the savings last as long as planned.

This article series takes the opposite approach. Retirement Spending is being treated here as the key independent variable. The future retiree first develops an estimate of their desired spending in retirement. Next the planning process incorporates assumptions about longevity, inflation, and investment returns. Finally, an estimate is obtained for the total savings at retirement necessary to sustain the desired retirement spending rate.
