How the Invesco QQQ Trust can turn $500 per month into $432,300

The Invesco QQQ Trust advanced 1,250% during the last two decades, compounding at 13.9% annually. But if dividend payments are included, the index fund achieved a total return of 1,470%, increasing at 14.7% annually.

Admittedly, anticipating an annual return of 14.7% may be overly optimistic. So, investors should introduce a margin of safety by assuming a more modest annual return of 12%. At that pace, $500 invested monthly in the Invesco QQQ Trust will be worth $105,200 in one decade and $432,300 in two decades.

Importantly, some investors may wish to save more or less than $500 per month. The chart below details how different monthly contribution amounts will grow over time, assuming an annual return of 12%.

Returns were determined using the investor.gov compound interest calculator.

Investors need two more pieces of information. First, the Invesco QQQ Trust has been very volatile throughout history because it is so heavily weighted toward the technology sector. In the last decade, the index fund fell more than 10% from its record high eight times, and it fell more than 20% from its record high four times.

Second, the Invesco QQQ Trust has a modest expense ratio of 0.20%, so shareholders will pay $20 annually on every $10,000 invested in the index fund. Comparatively, the average expense ratio of U.S. index funds and mutual funds was 0.34% in 2024.
