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.
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%.
The formula to determine the Rule of 114 is, to divide 114 by the interest rate equal to the number of years it will take to triple your money. For instance, if you deploy Rs 1,00,000 into an investment with a 12% annual expected return, then the time to triple is 114/12, or 9.5 years.
You simply take 72 and divide it by the interest rate number. 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.
What is the future value of $10,000 on deposit for 5 years at 6% simple interest? Hence the required future value is $13,000.
As per this thumb rule, the first 8 years is a period where money grows steadily, the next 4 years is where it accelerates and the next 3 years is where the snowball effect takes place.
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.
Hence, it will take 9.2 years for an investment to triple if it is compounded continuously at 12%.
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%.
Before buying an item, figure out how many times you'll use it. If it breaks down to $1 or less per use, I give myself the green light to buy it.
