The right investment can transform your finances, and investing in exchange-traded funds (ETFs) is one of the simplest ways to build life-changing wealth. Each fund contains dozens or hundreds of stocks, helping diversify your portfolio with minimal research or effort on your part.

A supercharged ETF to grow your savings
Growth ETFs can be incredibly powerful investments, and one popular choice is the Vanguard Mega Cap Growth ETF (MGK +0.60%).
Mega-cap stocks are generally defined as those with a market cap of at least $200 billion, and this ETF contains 66 of the largest U.S. stocks that still have growth potential. With a median market cap of $2.5 trillion, this fund is chock-full of industry-leading juggernauts from a variety of market sectors.
One of the advantages of this particular fund is its mix of stability and growth. Because mega-cap stocks are so large, they stand a better chance of surviving periods of market volatility. They may still experience short-term turbulence, but they’re more likely to recover over time compared to smaller companies.

Despite their relative stability, the mega-cap stocks within this ETF are also more likely to earn above-average returns. Over the last 10 years, the Vanguard Mega-Cap Growth ETF has earned total returns of more than 431%, compared to 262% for the S&P 500.
In other words, if you’d invested $5,000 a decade ago, you’d have around $26,000 with the Vanguard Mega Cap Growth ETF compared to just $18,000 with an S&P 500 ETF.
Just keep in mind that with most growth ETFs, you’re likely to see steeper downturns during periods of volatility compared to broad market funds. If you choose to invest in any growth fund, be prepared to hold your investment for at least five years or so to help limit the impact of short-term market turbulence.
Turning $100 per month into $949,000
There’s no way to know exactly how this ETF — or any investment — will perform in 2026 and beyond. However, examining this fund’s past performance can give you a rough idea of its earning potential.
Over the last 10 years, the Vanguard Mega Cap Growth ETF has earned an average rate of return of just over 18% per year. For comparison, the market as a whole has historically earned an average return of around 10% per year.
If you were to invest $100 per month, here’s approximately how that would add up over time depending on whether you’re earning average returns of 18% or 10% per year:
| Number of Years | Total Portfolio Value: 18% Avg. Annual Return | Total Portfolio Value: 10% Avg. Annual Return |
|---|---|---|
| 15 | $73,000 | $38,000 |
| 20 | $176,000 | $69,000 |
| 25 | $411,000 | $118,000 |
| 30 | $949,000 | $197,000 |

With enough time, $100 per month invested in this ETF could potentially grow to nearly $1 million. But even if this ETF underperforms or you can’t stay in the market for that long, it’s still possible to accumulate hundreds of thousands of dollars.
ETFs can be lucrative wealth-building opportunities, but time and consistency are key. By investing regularly and keeping a long-term outlook, the Vanguard Mega Cap Growth ETF could help you earn more than you might think.
