What Millennials Need to Retire Wealthy

Rule of 72

It’s official—Millennials are serious about building wealth.

According to a recent study, Millennials (ages 25 to 40) have an average of $51,300 in personal savings, while their retirement accounts have an average balance of $63,300.Âą

That’s far higher than it was just a few years ago. In 2019, they had saved just $23,000 for retirement.² They’ve nearly tripled their wealth in less than 3 years!

It’s no surprise. Few generations have gotten kicked in the pants quite like Millennials. Between recessions, pandemics, frenzied housing markets, and international instability, they’ve learned that wealth isn’t a luxury—it’s an absolute necessity.

But Millennials still have a long way to go before they retire wealthy. Here’s what they need if they’re going to arrive at their long-awaited destination…

Millennials must know—and use—the Rule of 72.

The Rule of 72 is a simple mental math shortcut that estimates when your money will double, given a fixed compounding interest rate. Here’s what it looks like…

72 Ă· interest rate = years to double

It’s simple, it’s powerful, and it might change the course of your financial future.

Let’s say you’re 35 years old with $60,000. That’s a solid start. But how can you turn $60,000 into $1 million by age 67?

Think of it like this—you need to double your money just over 4 times to reach $1 million.

Now, subtract your current age from your retirement age. That’s how long you have left to build wealth.

67 - 35 = 32 years

So you have 32 years to double your money just over 4 times. In other words, your money needs to double every 8 years.

Now it’s time to use the Rule of 72, but with a slight twist—swap the interest rate with the years for each double.

72 Ă· years for each double = interest rate needed

Plug in your numbers, and you get…

72 Ă· 8 years = 9% interest rate

In this scenario, you’d need just over a 9% interest rate to retire as a millionaire.

Armed with that knowledge, you’ll be better able to see through gimmicks like a “high-interest savings account” that offers .06% interest. You’ll also be left with just one question—where can you find an account with 9% interest?

Answer that question with your financial professional, and you’re on the right track for retiring wealthy.

Try the exercise above with your age and personal savings. What was the result? Then, contact a financial educator who can help you fine-tune a strategy to reach your retirement goals.
