Five ways to build your first $1 million

$1 million is an age-old retirement benchmark. It's also an entirely possible benchmark for most Americans. These five tips offer different methods one could go about earning $1 million for retirement. 

A million dollars is a frequently-cited retirement benchmark, though it’s a decidedly feeble attempt to put a number on a moving target. The value of a $1 million nest egg is substantially different depending on whether you’re living in Kansas City or San Francisco, retiring at 62 or 70, or planning on a life expectancy of 75 or 90.

Still, it’s the number at which many Americans feel they’ll be able to retire, and it’s certainly a good starting point. Someone who is able to amass $1 million by age 65 and expects to live another 20 years should be able to take out roughly $55,000 a year with inflation adjustments, according to this calculator.

How do you build that kind of capital? As it turns out, when you save can be just as important as what you save. “By starting early, an individual can harness the power of compound growth to build their wealth. The sooner the compounding begins, the greater the effect over the long term,” says Andy Tilp, president of Trillium Valley Financial Planning in Sherwood, Oregon.

Let’s say a 25-year-old college graduate currently earns $50,000, and his salary will increase 3% a year. Here are five ways he could build $1 million if he starts saving right now:

1. Deposit cash in savings

Savings account rates are dismal these days, but you can earn as much as 1% with an online bank. To build up $1 million at that interest rate, this person would have to save $1,700 a month. That’s 40% of his income, a savings rate not possible for most people.

Only after 35 years of salary increases would that $1,700 account for a more reasonable 15% of income, the percentage most experts recommend saving.

2. Save enough to grab 401(k) matching dollars

The average employer matching contribution to a 401(k) these days is dollar for dollar up to the first 6%, which is undeniably a hefty chunk of money. An employer match is invaluable, Tilp says, because it boosts a younger investor’s savings rate early on, so that money starts compounding sooner.

If this 25-year-old contributed enough to his 401(k) to grab a 6% match and invested at a 7% annual return, he’d have close to $1.8 million at age 65.

3. Get that 401(k) match, then max out a Roth IRA

If this person maxed out a Roth IRA (based on the current contribution limit of $5,500 per year, with an increase to $6,500 at age 50 due to catch-up contributions) in addition to getting his 401(k) match, he’d have another $1.2 million, for a total of $3 million at age 65.

This is probably the sweet spot, as it’s a goal achievable by many people. Maxing out an IRA and contributing 6% to a 401(k) puts this 25-year-old’s saving rate at a little above 15%. If you feel like that kind of savings rate isn’t within reach, consider this suggestion from Tilp: Each time you get a raise, increase your retirement contribution by the amount of your raise.

4. Max out a 401(k)

Let’s say our 25-year-old skipped the Roth and instead chose to max out his 401(k) each year, which currently has a pre-tax contribution limit of $18,000 and allows catch-up contributions of an extra $6,000 a year beginning at age 50. With an employer match, and again assuming a 7% return, he should have roughly $4.7 million at age 65.

That may very well be more than he needs, and saving $18,000 a year on a $50,000 salary is unrealistic for many.

5. Max out a 401(k) and a Roth IRA

Finally, this is the real get-rich-quick scheme: Maxing out both a 401(k) and a Roth IRA every year would lead to close to $6 million by the time our worker reached 65. This person would be living large in retirement — but very, very small while he’s young, saving close to half of his income. In short, it’s not an attainable strategy for many people.

The bottom line

Most people don’t have to worry about saving too much for retirement, and it’s unlikely that many 20-somethings will be able to put away half of their income each year.

But the message here is that you don’t need to. Building $1 million in capital for retirement is entirely possible on even a small salary, provided you start early, prioritize your savings efforts, set an asset allocation that keeps pace with the overall market over time and grab matching dollars from employers that offer them along the way.
