How much to invest in S&P 500 to be a millionaire?
If the S&P 500 outperforms its historical average and generates, say, a 12% annual return, you would reach $1 million in 26 years by investing $500 a month.
As a result, the broad-market index has an excellent historical track record of generating wealth. Over its history, the S&P 500 has generated an average annual return of 9%, including re-invested dividends. At that rate, even a middle-class income is enough to become a millionaire over time.
According to our calculations, a $1000 investment made in February 2014 would be worth $5,971.20, or a gain of 497.12%, as of February 5, 2024, and this return excludes dividends but includes price increases. Compare this to the S&P 500's rally of 178.17% and gold's return of 55.50% over the same time frame.
Once you have $1 million in assets, you can look seriously at living entirely off the returns of a portfolio. After all, the S&P 500 alone averages 10% returns per year. Setting aside taxes and down-year investment portfolio management, a $1 million index fund could provide $100,000 annually.
Assuming that you can earn this 10% average return over your investing career, if you are getting started investing this year and you want to become a millionaire in 30 years, you would need to invest $506.60 per month. This amount may seem like a lot, but it may actually be pretty doable for many people.
Here's how a 10.25% return would break down if you invested $5,000 at the beginning of each year over four decades. Data source: Author's calculations. As you can see from the chart, investing $5,000 annually in the S&P 500 would make you a millionaire in a little over 30 years, assuming average 10.25% annual returns.
Basic Info. S&P 500 10 Year Return is at 180.6%, compared to 174.1% last month and 161.9% last year. This is higher than the long term average of 114.4%.
| Discount Rate | Present Value | Future Value |
|---|---|---|
| 17% | $1,000 | $23,105.60 |
| 18% | $1,000 | $27,393.03 |
| 19% | $1,000 | $32,429.42 |
| 20% | $1,000 | $38,337.60 |
In 1980, had you invested a mere $1,000 in what went on to become the top-performing stock of S&P 500, then you would be sitting on a cool $1.2 million today.
For example, if an investment scheme promises an 8% annual compounded rate of return, it will take approximately nine years (72 / 8 = 9) to double the invested money.
Is it risky to only invest in S&P 500?
Investing in an S&P 500 fund can instantly diversify your portfolio and is generally considered less risky. S&P 500 index funds or ETFs will track the performance of the S&P 500, which means when the S&P 500 does well, your investment will, too. (The opposite is also true, of course.)
That's because your investment gives you access to the broad stock market. Meanwhile, if you only invest in S&P 500 ETFs, you won't beat the broad market. Rather, you can expect your portfolio's performance to be in line with that of the broad market. But that's not necessarily a bad thing.
These funds buy or sell very few shares each year, so most generate very little in terms of taxable capital gains, if any. But there are usually taxes due on S&P 500 funds' dividends. The exact amount of taxes varies by taxpayer, though.
Let's consider an investment in dividend stocks for $3,000 a month. If the average dividend yield of your portfolio is 4%, you'd need a substantial investment to generate $3,000 per month. To be precise, you'd need an investment of $900,000.
Too many people are paid a lot of money to tell investors that yields like that are impossible. But the truth is you can get a 9.5% yield today--and even more. But even at 9.5%, we're talking about a middle-class income of $4,000 per month on an investment of just a touch over $500K.
Historically, the stock market has an average annual rate of return between 10–12%. So if your $1 million is invested in good growth stock mutual funds, that means you could potentially live off of $100,000 to $120,000 each year without ever touching your one-million-dollar goose. But let's be even more conservative.
One way to become a millionaire
Over its history, the S&P 500 has generated an average annual return of 9%, including re-invested dividends. At that rate, even a middle-class income is enough to become a millionaire over time. $500 a month, for example, is less than 10% of the median U.S. household's monthly income.
S&P 500 Monthly Return is at 3.10%, compared to 5.17% last month and 3.51% last year. This is higher than the long term average of 0.56%. The S&P 500 Monthly Return is the investment return received each month, excluding dividends, when holding the S&P 500 index.
The actual rate of return is largely dependent on the types of investments you select. The Standard & Poor's 500® (S&P 500®) for the 10 years ending December 31st 2023, had an annual compounded rate of return of 15.2%, including reinvestment of dividends.
How much will $100k be worth in 20 years? If you invest $100,000 at an annual interest rate of 6%, at the end of 20 years, your initial investment will amount to a total of $320,714, putting your interest earned over the two decades at $220,714.
Does 401k double every 7 years?
One of those tools is known as the Rule 72. For example, let's say you have saved $50,000 and your 401(k) holdings historically has a rate of return of 8%. 72 divided by 8 equals 9 years until your investment is estimated to double to $100,000.
| Period (start-of-year to end-of-2023) | Average annual S&P 500 return |
|---|---|
| 10 years (2014-2023) | 11.02% |
| 15 years (2009-2023) | 12.63% |
| 20 years (2004-2023) | 9.00% |
| 25 years (1999-2023) | 7.18% |
Investing $1,000 a month for 20 years would leave you with around $687,306. The specific amount you end up with depends on your returns -- the S&P 500 has averaged 10% returns over the last 50 years. The more you invest (and the earlier), the more you can take advantage of compound growth.
To turn $5,000 into more money, explore various investment avenues like the stock market, real estate or a high-yield savings account for lower-risk growth. Investing in a small business or startup could also provide significant returns if the business is successful.
If you're still investing $100 per month, you'd have a total of around $518,000 after 35 years, compared to $325,000 in that time period with a 10% return. There are never any guarantees in the stock market, but with the right strategy, a little cash can go a long way.
