Warren Buffett has spent more than eight decades outperforming Wall Street. Yet, ordinary Americans can follow a much simpler strategy to build wealth.

"America has been a wonderful place to invest money," Buffett told CNBC's Becky Quick in an interview (1).

When Buffett bought his first stock in 1942, he recalled, the Dow Jones Industrial Average had just crossed 100. At the time of the interview, it was hovering around 52,000 (roughly 520 times higher) before counting the dividends investors could have collected and reinvested. So far in 2026, the Dow Jones has hit a new record high 24 times (2).

"The village idiot could have made it," Buffett joked.

His point was that investing in productive American businesses has historically created tremendous wealth. In his 2018 letter to Berkshire Hathaway shareholders, for instance, Buffett calculated that a hypothetical $114.75 invested in a no-fee S&P 500 index fund in 1942 would have grown to $606,811 by January 2019 with dividends reinvested (3).

Despite this advantage, investors can undermine their positions with fashionable assets, constant trading or needlessly complicated strategies.

Once investing becomes unnecessarily complicated, Buffett warned, it starts looking like gambling.

Here's how you can put his simple philosophy to work for your retirement.

Own a broad piece of American business

Buffett has made billions identifying exceptional individual companies. But his regular recommendation for everyday investors is far easier to follow.

"My regular recommendation has been a low-cost S&P 500 index fund," Buffett wrote in his 2016 letter to shareholders (4).

An index fund allows you to invest in a large collection of companies through a single purchase. The Securities and Exchange Commission (SEC) says this kind of diversification can reduce portfolio risk, although it can't eliminate losses (5). Popular options include the Vanguard S&P 500 ETF (NYSEARCA: VOO) and the iShares Core S&P 500 ETF (NYSEARCA: IVV).

If you prefer the hands-off, tech-forward approach to building wealth, Vanguard's Digital Advisor puts the investing expertise of one of the world's largest asset managers right at your fingertips.

It takes the guesswork out of investing by building a personalized portfolio for you using Vanguard's well-known low-cost ETFs and mutual funds — then keeps things running smoothly with automatic rebalancing.

The platform also offers guidance on saving for retirement and lets you set additional goals as your life evolves. It can even help you think through debt repayment strategies, potentially freeing up more cash to invest toward your long-term plans.

With a minimum investment of just $100, it's an easy way to get started with professionally guided investing.

For every $10,000 in an all-index portfolio, you'll pay approximately $15 to $16 per year.*

You can even test-drive the Vanguard experience with no advisory fees for the first 90 days.

*All investing is subject to risk, including the possible loss of the money you invest.

Starting with smaller investments

The real beauty of ETF investing is its accessibility. Anyone, regardless of wealth, can take advantage of it.

Even small amounts can grow over time with tools like Acorns, an app that automatically invests your spare change.

Signing up for Acorns takes just minutes: All you have to do is link your cards, and Acorns will round up each purchase to the nearest dollar, investing the difference — your spare change — into a diversified portfolio of ETFs managed by experts at leading investment firms like Vanguard and BlackRock.

With Acorns, you can start building the habit of investing in a dividend ETF with as little as $5. Plus, if you sign up today, Acorns will add a $20 bonus to give your portfolio an early boost.

Understand what you own

Buffett treats a stock as a piece of an actual business. In the interview with CNBC, he said the investing trick is finding businesses that can earn high returns on capital for extended periods.

This means that before buying an individual company, you might want to consider how it earns money, whether it has sustainable advantages, how much debt it carries and whether its valuation reflects realistic expectations.

Your ideal mixture of stocks, bonds and cash depends on your age, retirement date, income needs and tolerance for losses. According to the SEC, investors with shorter time horizons may prefer less volatile investments than those who have decades to recover from a downturn (6).

For older investors with larger portfolios, these financial decisions often become increasingly nuanced. Managing withdrawals, minimizing tax exposure and ensuring long-term sustainability can require greater coordination and strategic planning.
