How Much Money Can You Make Investing in the S&P 500? A 50-Year-Old's Retirement Journey (2025)

Imagine starting your retirement journey with a substantial nest egg, all thanks to a simple yet powerful investment strategy. But here's the eye-opener: if a 50-year-old invests just £500 a month into S&P 500 shares, the results by retirement age could be life-changing. And this is the part most people miss—it’s not just about the money; it’s about the power of consistency and compounding over time. Let’s dive into how this could work for you.

Investing in the S&P 500 has long been a favorite strategy for those seeking steady, long-term growth. Even in the past five years, the index has created staggering wealth, largely fueled by the performance of the ‘Magnificent Seven’ stocks. For instance, someone who invested £1,000 in a passive index tracker five years ago would now have over £2,085—more than double their initial investment. But here’s where it gets controversial: if they had instead chosen to invest exclusively in Nvidia, that same £1,000 would now be worth a jaw-dropping £13,407! This raises the question: Can the largest U.S. stocks keep delivering such extraordinary returns? And for a 50-year-old investor, how much could they realistically accumulate by the time they retire at 67?

Setting Realistic Expectations

The S&P 500’s 108% total return over the last five years is undeniably impressive, translating to an average annualized return of 15.8%. Compare that to the historical average of 10% for the U.S. stock market, and it’s clear why this period stands out. But is this sustainable? Likely not. The past five years have been exceptional, driven by unprecedented events like the 2020 stimulus, the rapid post-pandemic recovery in 2021, and the continued dominance of tech giants like Nvidia. Such periods of outperformance are rare and are often followed by a reversion to the mean.

History tells us that boom years are typically followed by slumps. For example, the dotcom bubble (1995–2000) saw a 22% average annual return, only to be followed by a 40% market drawdown from 2000 to 2002. Similarly, the financial crisis boom (2003–2007) yielded 14% annually, but the market then plummeted by 57% in 2008–2009. While the post-pandemic boom (2020–2025) has been remarkable, time will tell if it follows the same pattern.

The Good News for Late Starters

Even if the S&P 500 reverts to its long-term average of 10%, that’s still more than enough to build significant retirement wealth. For a 50-year-old investing £500 monthly, compounding could turn that into £266,132 by age 67. That’s right—a quarter-million pounds, just by staying consistent and letting time work its magic. But here’s a thought-provoking question: Is relying solely on the S&P 500 enough, or should investors explore additional strategies to maximize their gains?

Maximizing Wealth: The Stock Picker’s Advantage

While a £266,132 retirement fund is impressive, skilled stock pickers could potentially unlock even greater wealth. For example, beating the market by just 3% annually could add roughly another £100,000 to your pension pot. Of course, investing always comes with risks, but certain S&P 500 companies are worth considering. Take Toast (NYSE:TOST), a cloud-based restaurant management platform I’ve recently added to my portfolio.

Toast is revolutionizing the restaurant industry by offering all-in-one solutions for payment processing, ordering, delivery, payroll, and even capital financing. With 156,000 U.S. locations already on board, its adoption is accelerating, driving phenomenal revenue and profit growth. However, it’s not without challenges. Competition limits its pricing power, and its reliance on transaction fees makes it vulnerable to economic downturns. Yet, with over 700,000 restaurants in the U.S. alone and significant international expansion potential, I remain optimistic about its long-term growth. But what do you think—is Toast a risky bet or a smart addition to a growth-focused portfolio?

In conclusion, whether you’re starting at 50 or earlier, the S&P 500 offers a robust foundation for retirement planning. But the real question is: Are you willing to explore beyond the index to potentially amplify your gains? Let’s discuss—do you think sticking to the S&P 500 is enough, or is there value in taking calculated risks with individual stocks? Share your thoughts below!
