What is the rule of 72 credit card?
The Bankrate promise
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.
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.
If your money is in a savings account earning 3% a year, it will take 24 years to double your money (72 / 3 = 24).
You can also apply the Rule of 72 to debt for a sobering look at the impact of carrying a credit card balance. Assume a credit card balance of $10,000 at an interest rate of 17%. If you don't pay down the balance, the debt will double to $20,000 in approximately 4 years and 3 months.
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.
The value 72 is a convenient choice of numerator, since it has many small divisors: 1, 2, 3, 4, 6, 8, 9, and 12. It provides a good approximation for annual compounding, and for compounding at typical rates (from 6% to 10%); the approximations are less accurate at higher interest rates.
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.
The Buffett Rule is the basic principle that no household making over $1 million annually should pay a smaller share of their income in taxes than middle-class families pay. Warren Buffett has famously stated that he pays a lower tax rate than his secretary, but as this report documents this situation is not uncommon.
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.
How long will it take $1000 to double at 6% interest?
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. This calculator flips the 72 rule and shows what interest rate you would need to double your investment in a set number of years.
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%.
Expert-Verified Answer
The time value of money states that a dollar today is worth more than a dollar in the future due to the potential to invest and earn interest. In this case, $10,000 right now has a higher time value than $20,000 one year later.
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.
Choose the right career
And one crucial detail to note: Millionaire status doesn't equal a sky-high salary. “Only 31% averaged $100,000 a year over the course of their career,” the study found, “and one-third never made six figures in any single working year of their career.”
When you invest, your money can increase or decrease depending on the day-to-day changes in the market, so there is much more risk. "An FDIC-insured savings account is nearly risk-free for short-term savings and is not subject to market fluctuations," says Sebastian Rollén, senior investing researcher at Betterment.
Example of the Rule of 72
Dividing 72 by the interest rate of 8 gives the number of years required to double the investment, which in this case is 9 years. So, if an individual invests Rs. 10,000 at an 8% annual interest rate, they can expect the investment to double to Rs. 20,000 in approximately nine years.
Although Einstein is often credited with discovering the rule of 72, it was more likely discovered by an Italian mathematician named Luca Pacioli in the late 1400s. Pacioli also invented modern accounting.
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%.
The rule is an easy-to-remember calculation: Simply divide 72 by the annual rate of return for an investment. If an investment has an expected annual rate of return of 6%, that means it can be expected to double in 12 years.
What is the magic number 72?
The magic number
The premise of the rule revolves around either dividing 72 by the interest rate your investment will receive, or inversely, dividing the number of years you would like to double your money in by 72 to give you the required rate of return.
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.
