Why the "80% Replacement Rule" isn't for Everyone

What if the "80% replacement rule" that many advisors preach could be costing you years of freedom?

In our opinion, this widely accepted benchmark might be one of the most significant oversimplifications in retirement planning today.

For those of you that don’t know, the 80% replacement rule generally means that you will need to replace at least 80% of your annual salary from your working years to live comfortably in retirement.

To bring our opinion to light, let’s talk about a fictional couple, David and Susan, who delayed retirement by three years following this common thought, blindly.

When they finally discussed their situation with their financial advisor, they discovered they had been saving far more than necessary all along.

Unfortunately, those were three extra years of their lives that they'll never get back.

The truth is, your income level often changes how much you actually need in retirement, but this crucial detail can get buried beneath one-size-fits-all advice.

If you're earning $50,000 annually, you might indeed need to replace about 80% of that income.

But what if you're earning closer to $200,000? Some research shows you might only need to replace about 55%.

Think about that for a moment: that difference could potentially represent not only additional unnecessary savings but also unnecessary time spent to accrue that savings.

You might be wondering here, why such a massive gap? And how do you find your personal number that could help you feel more confident in your journey?

Let’s take a look at three critical factors that we see so often overlooked.

First, our progressive tax system means higher earners face higher tax rates during working years that could potentially dramatically drop in retirement.

When you're no longer earning your salary, your tax burden could theoretically decrease—especially for those in higher income brackets.

Let’s break this down: Say we have a hypothetical client named Richard and he was earning $220,000 annually before retirement, paying nearly $45,000 in federal taxes per year.

In his first year of retirement, despite maintaining a comfortable lifestyle, his specific plan resulted in a tax bill that dropped to just $12,000—a reduction of almost 75%.

This caveat could have an immediate boost in one’s ability to spend that cookie-cutter calculators may completely miss.

Second, you have to take into account the potential for elimination of certain work-related expenses when you retire.

Daily commuting costs, professional wardrobe requirements, workplace meals, and even those small daily coffees can add up significantly.

The Third factor to account for is that your essential spending baseline could shift as well.

Basic necessities like housing, food, and utilities consume a much larger portion of a lower earner's budget, while higher earners generally allocate more to discretionary spending—areas which may be more easily adjusted in retirement.

But these are just a few factors that many in the financial industry might disregard when planning for one’s retirement journey.

What if the way you'll actually spend money throughout retirement isn't what’s been forecasted at all?

In the majority of cases we’ve witnessed, retirement spending isn't a straight line—it follows what some refer to as the "smile pattern" with three distinct phases that mirror life's natural journey.

Yet most financial calculators plan as if your spending will remain constant throughout your entire retirement, or simply rise with inflation in a straight line, year after year.

This fundamental disconnect could be causing you to live with artificial restrictions during what could be viewed as one’s most enjoyable years.

Picture your spending like a smile on a graph: starting high, dipping in the middle, then rising again later in life.

Really honing in on understanding this pattern has changed multiple trajectories and outcomes during retirement planning conversations we’ve had.

By mapping one’s specific retirement journey against this spending pattern rather than assuming constant expenses, we can gain a better understanding of when the opportune time to move on to the next chapter in life might be.

During the beginning years of retirement, you may be spending more due to your new found freedom. Travel, going out with friends and picking up new hobbies may become larger parts of your budget. As you enter the next phase of retirement generally from ages 75-85, that spending statistically seems to slow down for one reason or another. Finally, during your later years in life, after 85, spending usually seems to rise again but for another reason, specifically medical.

The U.S. Bureau of Labor Statistics reports that healthcare expenses in retirement cost Americans an average of $7,030 each year, representing 13.5% of overall expenses—a percentage that typically increases in later years while other categories decrease.

By accounting for this natural spending pattern rather than assuming constant inflation-adjusted withdrawals, some research indicates you could potentially significantly increase your initial withdrawal rate when compared to constant-spending models.

This thought pattern may also justify starting retirement with less accumulated wealth while maintaining the same probability of success.

The Final Word:

Of course, everyone’s situation is different and this is not advice for any specific situation.

By calculating your personalized income replacement rate depending on your current earnings and mapping your anticipated spending across life's natural chapters, you might be better positioned to fully embrace each day of your retirement journey with confidence.

One key takeaway we like to speak about is the understanding that money is merely a tool for creating a life of purpose, connection, and joy.
