The Art of Managing Retirement Assumptions

A retirement plan is built on a set of assumptions that can’t be validated until it’s too late. One key to successful retirement planning is carefully setting assumptions and revising them often.

Retirement calculators make it so easy. Pick a retirement date. Estimate your living expenses in retirement and choose an inflation rate. Figure out a rate of return for your investments. Guess how long you think you’ll live. Put these assumptions into the calculator, and it will tell you just how much you need to have at retirement in order to receive the income stream you desire.

The problem is your assumptions could be off. And if they’re off by just a little, they could skew the result by a significant amount over your remaining life. Consider this:

  • If a portfolio withdrawal rate is set to last to age 90 and you make it to your 91st birthday, the plan failed. You can’t do retirement projections without making some assumptions. But most of the self help tools out there make assumption-setting seem too easy. Some even have default settings, which imply that the metric in question — a 3% inflation rate, for example — is what any reasonable person would choose. To change it would be to go against the conventional wisdom, a scary proposition for anyone who isn’t even sure what the inflation rate is based on.

For example, people often:

  • Underestimate retirement spending. Most people have not tried to estimate how much money they will need for retirement. Those who have calculated this amount often underestimate what they will need to maintain their pre-retirement lifestyle in retirement.
  • Don’t plan for contingencies. Many workers will retire before they expect to because of disability, job loss, or the need to care for a spouse, parents, or other family members.
  • Underestimate health care. Many people underestimate their chances of needing long term care.
  • Take the cash. Although people find guaranteed lifetime income attractive, they usually choose to receive retirement plan benefits in a lump sum, failing to recognize the difficulty of self-insuring longevity.
  • Fail to explore investment options. Many workers misunderstand investment returns and how investment vehicles work.
  • Underestimate income. Workers misunderstand what their primary sources of income will be in retirement, and may be disappointed when trying to live on the income available to them.
  • Don’t seek help. A significant number of retirees and pre-retirees do not seek the help of an advisor, yet they indicate a strong desire to work with a qualified professional.

Here are some things you can do to get ready for retirement:

  • Establish initial assumptions that are as accurate as possible. This requires considerable knowledge and judgment — the opposite of “pick a number.” Get some help.
  • Revise the assumptions going forward to keep the plan on track. As new information comes in and the plan plays out, the original assumptions may need to be changed and the plan revised accordingly.
  • Get help. Advisors are experienced in setting assumptions and can help you set reasonable assumptions for your particular plan. Consider the following issues when discussing assumptions with your advisor.

Reasonableness of the assumption. This is one of the main challenges for people doing retirement planning on their own: they simply don’t know what is reasonable, especially when it comes to financial matters. Is it reasonable to expect a consistent annual 6% rate of return over the next 30 years? Is a 3% inflation rate realistic if the mortgage is paid off and the bulk of your spending in retirement is on food, energy, travel, and health care? Are tax rates likely to go up, down, or stay the same?

Potential consequences if you’re wrong. Some assumptions carry such drastic consequences if they are wrong that it influences how the assumption is set to begin with. Outliving one’s life expectancy is just about the worst, because by the time you find it out, it’s too late to do anything about it. This is why most advisors recommend a life expectancy of 90 to 100 years rather than the average life expectancy past which half of all people will live. Underestimating health care needs can be another disastrous assumption.

The interplay of multiple assumptions is that some assumptions impact one another. For example, retirement age and life expectancy determine how many years you have left to save and how long the portfolio must last in retirement. By extending one, you shorten the other, and vice versa. Two other assumptions that impact one another are estimated expenses and life expectancy: the longer the withdrawal period, the less annual income you may receive, and vice versa — unless you adjust something else, such as the expected rate of return. The permutations are endless and may be one reason people get bogged down with retirement planning.

At the same time, you have information that may influence the assumptions that should be used. For example, you may decide to shorten or extend the life expectancy assumption based on what you know about your particular family history, health status, and lifestyle. Another important factor is your willingness to revise your goals if one or more of the major retirement risks should threaten to play out. Ask yourself if you would be willing to work longer (or go back to work if already retired) or lower your standard of living in order to either save more now or reduce expenses in retirement.

When planning your retirement, visualize your life all the way through and establish appropriate assumptions for each phase, including a final phase that may require several years of living assistance or nursing care. Collaborate with your advisor. You and your advisor each have information and insights that can increase the accuracy of assumptions. Your advisor’s understanding of the markets and the economy, his experience with clients who are already retired, and his number crunching ability can give you a professional advantage over web-based retirement calculators designed for individuals to use on their own. The less willing you are to revise your goals, the more conservative the assumptions need to be.
