The Power of Investing 4% More

If you struggle to invest at least 20% of your income for retirement, the good news is that you could still build substantial wealth by investing what you can. If you can invest just 4% more of your income starting in your 20s or 30s, you could make a huge difference to your net worth by the time you turn 62—even if you make $30k to $55k a year.

Investing 4% more on a $30k income

If you earn $30k a year, investing 20% of your income is just not possible unless you split your housing expenses with a roommate or partner. But if you can invest anything at all—even 4% of your gross income or $100 a month—your contributions could significantly boost your progress toward financial independence.

But if investing 4% is too much, investing 3% of your income ($75 a month), 2% of your income ($50 a month), or even 1% of your income ($25 a month) could still help you build wealth.

Your most important wealth-building tool is time, not money, which is why you can still build wealth on a lower income. The longer your money is invested, the more money you have.

If you earn $30,000 a year and invest $100 a month—just 4% of your gross income—starting in your 20s, you could have an extra $308k to $774k by the time you turn 62 if you average a 10% rate of return:

Making incremental progress helps your money work smarter, not harder.

Small progress matters because your most powerful wealth-building tool is time, not money. What matters most to creating compound interest is the time that your money is invested, not necessarily how much you invest.

The longer your money is invested, the more money you could have. Smaller amounts of money invested for longer period of time could potentially build much more wealth than larger amounts of money invested for a shorter period of time.

Procrasting on investing because you don’t think that incremental progress matters is the worst mistake you could make because you’re wasting your most powerful wealth-building tool: time.

The longer you wait to start investing, the harder building wealth becomes. So investing what you can is just letting your money work smarter, not harder.

If you invest $100 a month from age 20 to age 60 and you average a somewhat conservative 8% rate of return, you could have $349,100 by the end of that time period. But you will have only contributed $48,000 of your own money—in this scenario, you’ve gained $310,100 in compound interest:

A chart shows that if you invest $100 a month for 40 years, you will have contributed $48,000 and your money could grow to $349,100 after 40 years. — Investing $100 a month for 40 years with an 8% rate of return

If you invest $1,000 a month for 15 years and get an 8% rate of return, your money could grow to $346,038 by the end of that time period. However, you will have contributed $180,000 of your own money, so you will have gained only $166,038 in compound interest.

A chart shows that if you invest $1000 a month for 15 years and get an 8% rate of return, your money could grow to $346,038. $180,000 of that amount would be money that you contributed. — Investing $1,000 a month for 15 years with an 8% rate of return

In the first scenario, you contributed $48,000 of your own money, which is $132,000 less than what you contributed in the second scenario ($180,000), but you ended up with $144,062 more in compound interest.

If you invest what you can and harness the power of small progress, your money grows more efficiently.

Even though you’re investing smaller amounts of money for a longer period of time ($100 a month for 40 years), your money has grown significantly more than the scenario where you invested large amounts of money for a shorter period of time ($1,000 a month for 15 years).

When it comes to investing, less is more if you harness the power of your most powerful wealth-building tool: time.

What if you can’t invest 4% more?

If you can’t invest 4% more (or even if you can’t invest 4% in the first place), you should start by investing what you can. You could still make massive progress toward financial freedom if you invest 3%, 2%, or 1% more of your income, even if you earn $30k to $55k a year. Check out these articles to see how your wealth could grow if you harness the power of small, incremental progress:

Is investing 4% more enough?

Whether or not investing 4% more is enough depends on how much you’re already investing and whether or not you’re on track to meet your inveting goals.

If you’re starting from zero, you shouldn’t stop at investing 4% more: You should work your way up to investing at least 20% of your income for retirement.

But even though investing 4% more won’t be enough in most cases, making this change could potentially empower you to retire early, especially if you make this change in your 20s or even early 30s.
