What is the 72 hour rule in stocks?
The classic rule of 72 formula delivers the amount of time it takes to double an investment at a given compound interest rate, meaning the interest is calculated on the initial amount and the amount of accrued interest each subsequent year. That is accomplished by dividing 72 by the expected rate of return.
The Rule of 72 is a quick, useful formula that is popularly used to estimate the number of years required to double the invested money at a given annual rate of return. Alternatively, it can compute the annual rate of compounded return from an investment, given how many years it will take to double the investment.
The Rule of 72 is a calculation that estimates the number of years it takes to double your money at a specified rate of return. If, for example, your account earns 4 percent, divide 72 by 4 to get the number of years it will take for your money to double. In this case, 18 years.
If the index rises at its historical average of around 10%, you'd double your money in about 7.2 years (72/10 = 7.2). If you believed that the S&P 500 is more likely to return, say, 15% due to strong earnings, you'd double your money in 4.8 years (72/15 = 4.8).
Using the Rule of 72, you would see that your investments should double roughly every 7.2 years (72 divided by 10). This allows the investments that you make this year to double four times before retirement (30 divided by 7.2).
Errors and Adjustments
The rule of 72 is only an approximation that is accurate for a range of interest rate (from 6% to 10%). Outside that range the error will vary from 2.4% to 14.0%. It turns out that for every three percentage points away from 8% the value 72 could be adjusted by 1.
How the Rule of 72 Works. For example, the Rule of 72 states that $1 invested at an annual fixed interest rate of 10% would take 7.2 years ((72/10) = 7.2) to grow to $2. In reality, a 10% investment will take 7.3 years to double (1.107.3 = 2). The Rule of 72 is reasonably accurate for low rates of return.
Final answer:
It will take approximately 15.27 years to increase the $2,200 investment to $10,000 at an annual interest rate of 6.5%.
Try Flipping Things
Another way to double your $2,000 in 24 hours is by flipping items. This method involves buying items at a lower price and selling them for a profit. You can start by looking for items that are in high demand or have a high resale value. One popular option is to start a retail arbitrage business.

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.
Buffett's headline rule is “don't lose money” and his second rule is “don't forget rule one”. This might sound obvious. Of course, it is. But it's important to look at the message within.
Warren Buffet's 2013 letter explains the 90/10 rule—put 90% of assets in S&P 500 index funds and the other 10% in short-term government bonds.
Buffett has a simple investment rule on retained earnings to assess management's capital allocation. He discussed this concept in a 1983 letter to shareholders. “We test the wisdom of retaining earnings by assessing whether retention, over time, delivers shareholders at least $1 of market value for each $1 retained.”
The so-called Rule of 42 is one example of a philosophy that focuses on a large distribution of holdings, calling for a portfolio to include at least 42 choices while owning only a small amount of most of those choices.
1 At 10%, you could double your initial investment every seven years (72 divided by 10). In a less-risky investment such as bonds, which have averaged a return of about 5% to 6% over the same period, you could expect to double your money in about 12 years (72 divided by 6).
One can also use this to compute the returns a portfolio should generate to double money in a given time period. If you want to double it in five years, the portfolio should be invested such that it yields 72/5=14.4%.
One awesome thing that you can take advantage of is compound interest. It may sound like an intimidating term, but it really isn't once you know what it means. Here's a little secret: compound interest is a millionaire's best friend. It's really free money.
Can you live off interest of one million dollars?
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.
So, if the interest rate is 6%, you would divide 72 by 6 to get 12. This means that the investment will take about 12 years to double with a 6% fixed annual interest rate.
Final answer: To reach $7,500 with an 8% interest rate, it would take approximately 9.7 years. Using a calculator, we find that time is approximately 9.7 years.
Hence, it will take 8.8 years to double the investment.
