How long does it take invested money to grow?
Do you know the Rule of 72? It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.
A common rule of thumb, the rule of 72, states that you can know how long it'll take for your investment to double by dividing 72 by the rate of return. A 10% annual return means your money should double every 7.2 years.
Discount Rate | Present Value | Future Value |
---|---|---|
10% | $1,000 | $6,727.50 |
11% | $1,000 | $8,062.31 |
12% | $1,000 | $9,646.29 |
13% | $1,000 | $11,523.09 |
Here's the formula:
Years to double your money = 72 ÷ assumed rate of return. Consider: You've got $10,000 to invest and you hope to earn 8% over time. Just divide 72 by 8—which equals 9. Now you know it'll take approximately 9 years to grow your $10,000 to $20,000.
Years Invested | Balance At the End of the Period |
---|---|
10 | $102,422 |
20 | $379,684 |
30 | $1,130,244 |
40 | $3,162,040 |
Let's say you want to become a millionaire in five years. If you're starting from scratch, online millionaire calculators (which return a variety of results given the same inputs) estimate that you'll need to save anywhere from $13,000 to $15,500 a month and invest it wisely enough to earn an average of 10% a year.
If you had invested $1,000 in Google stock on Aug. 19, 2004, today, you would have $60,107. Likewise, if you had invested $1,000 in an index fund replicating Nasdaq, you would have $9,000. A similar $1,000 investment in an index fund that replicates the S&P 500 would be worth $4,815.
Over the years, that money can really add up: If you kept that money in a retirement account over 30 years and earned that average 6% return, for example, your $10,000 would grow to more than $57,000. In reality, investment returns will vary year to year and even day to day.
Investing $100 per month, with an average return rate of 10%, will yield $200,000 after 30 years. Due to compound interest, your investment will yield $535,000 after 40 years. These numbers can grow exponentially with an extra $100. If you make a monthly investment of $200, your 30-year yield will be close to $400,000.
The short answer to what happens if you invest $500 a month is that you'll almost certainly build wealth over time. In fact, if you keep investing that $500 every month for 40 years, you could become a millionaire. More than a millionaire, in fact.
Is 25 too late to invest?
No matter how old you are, the best time to start investing was a while ago. But it's never too late to do something. Just make sure the decisions you make are the right ones for your age—your investment approach should age with you.
Is it too late to start investing if you're older than 30? So if you can start investing before 30, I encourage you to do that. But if you're 32 and that ship has sailed, don't worry, you are not behind. Most Americans retire at 61.
This chart shows you how, over a period of 30 years, investing $50 every week could grow your portfolio to more than $1 million. Chart by author. Assuming a 15% annual growth rate (on average), a $50 per-week investment could grow to a value of more than $1.5 million after 30 years.
Suppose you're starting from scratch and have no savings. You'd need to invest around $13,000 per month to save a million dollars in five years, assuming a 7% annual rate of return and 3% inflation rate. For a rate of return of 5%, you'd need to save around $14,700 per month.
So, what do you need to do to have $1 million after five years? If you have never invested before (you have zero balance in your investment account), you need to invest approximately $12,821 at the end of every month for the next five years.
Annual compounding results in slightly lower numbers, while monthly or weekly compounding results in higher numbers. At a 12% average return, it would take a monthly investment of around $4,350 to become a millionaire in 10 years. At a 14% return, it would take around $3,875 per month.
The simplest path from $100,000 to $1 million
The simplest way to invest your money is by using a simple broad-market index fund. An index fund that tracks the S&P 500 or a total stock market index typically has low fees, and it's going to closely match what the overall stock market returns.
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.
Imagine you wish to amass $3000 monthly from your investments, amounting to $36,000 annually. If you park your funds in a savings account offering a 2% annual interest rate, you'd need to inject roughly $1.8 million into the account.

What if you invested $1,000 in Netflix 10 years ago?
So, if you had invested in Netflix ten years ago, you're likely feeling pretty good about your investment today. A $1000 investment made in March 2014 would be worth $9,728.72, or a gain of 872.87%, as of March 4, 2024, according to our calculations. This return excludes dividends but includes price appreciation.
In 1998, Google's founders got their first investment, a $100,000 check. It took some time to deposit because they had not set up a bank account.
To potentially turn $10k into $100k, consider investments in established businesses, real estate, index funds, mutual funds, dividend stocks, or cryptocurrencies. High-risk, high-reward options like cryptocurrencies and peer-to-peer lending could accelerate returns but also carry greater risks.
The value of the $1 million today is the value of $1 million discounted at the inflation rate of 3.2% for 40 years, i.e., 1 , 000 , 000 ( 1 + 3.2 % ) 40 = 283 , 669.15.
