As most retirees will tell you, one of the most important preparations you can make for a fulfilling, low-stress retirement is getting clarity on your retirement income and expenses. Probably most important is setting up a retirement budget that takes into consideration your various sources of income, including Social Security, any pensions to which you’re entitled, and your projected income stream from investments and savings. Your budget should also include a careful estimate of your anticipated expenses, including healthcare, living expenses, travel, and costs for any other activities and needs you anticipate. All of this is foundational to being able to embrace and enjoy your retirement lifestyle.
But is there a way to put in place some guidelines or “guardrails” that can help you ensure that your retirement spending doesn’t outstrip your sources of income over time? After all, most retirees list “outliving my money” (otherwise known as “longevity risk”) as a key concern as they approach and enter retirement, and the best way to avoid that is to make sure that your income projections balance out with your expected expenses over time.
Allowing for Changes in Expenses, Income, and Savings
What we’re talking about is how to control for longevity risk and plan for sustainable spending in retirement. We all know that expenses aren’t the same year to year, or even month to month. They go up and down in tandem with the circumstances of life. If you live in a colder climate, your heating bills are higher during the winter, and if you live farther south, your bills are probably higher in the summer, when the air conditioning is running nonstop. During the holidays, you may spend more on groceries and entertainment as you receive family and friends. You may even go through a period of higher healthcare costs when an injury or disease requires you to pay more deductibles and copays than normal.
But in the same way, your retirement income is dynamic. For one thing, those collecting Social Security can typically look forward to some sort of cost-of-living adjustment (COLA) in years when inflation is elevated (for example, the 2027 Social Security COLA is estimated at around +3.4%, though it won’t be officially announced until October 2026) and some pensions also allow for periodic cost-of-living increases. Beyond these sources, your withdrawal rate from savings, investment, and retirement accounts can also move up and down, depending on various market and portfolio factors.
When should spending increase or decrease?
For example, in years when financial markets are on the upswing, your investments are likely to be increasing in value. So, depending on the percentage your plan stipulates for withdrawals (some retirees follow the “4% rule,” though this can vary), you may be able to increase your withdrawal percentage a bit in years with rising markets, and nudge it lower in years when asset values are declining. By doing this, it is possible to maintain your income at a sustainable level while still enjoying periodic “raises” when market conditions permit. This flexible, “guardrail” approach allows you to avoid overspending when markets are less favorable, but it also permits you to avoid underspending (and potentially missing out on opportunities you would otherwise enjoy) during periods when the markets are rising. The end result is a sustainable spending plan that takes into consideration portfolio volatility and your projected income needs over your expected lifetime.
How do retirement income guardrails work?
Let’s say that generally, your retirement spending plan calls for withdrawing 4% of your total portfolio value yearly. If you have a $1 million dollar portfolio, that means you’re pulling $40,000 dollars each year, on average, from your holdings to support your retirement lifestyle. Now, let’s assume that in a given year, your holdings increase in value by 7.5% (the average increase in the S&P 500 for the last 30 years, net of inflation). You might opt to withdraw a bit more than 4% that year. But suppose that the very next year, the market falls by 5%. In that case, you might choose to reduce your withdrawal percentage. By adjusting your withdrawals to keep them within the “guardrails” of the changes in your portfolio value, you can course-correct, resting in the assurance that your spending plan is remaining within the appropriate boundaries for your lifestyle needs over time.
How can I create a retirement spending plan with “guardrails”?
Creating a flexible, sustainable plan for retirement spending is greatly enhanced by the assistance and advice of a fiduciary, professional financial advisor. Your advisor can work with you to assess all your sources of income, project your expenses, and develop a sustainable, flexible spending model that can allow you a less stressful, more carefree retirement lifestyle.
