However, the Rule of 72 is based on a few assumptions that may not always be accurate, such as a constant rate of return and compounding period. It also does not take into account taxes, inflation, and other factors that may impact investment returns.
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.
Disadvantages Explained
Works against consumers making minimum payments on high-interest loans or credit card debts: If you only pay the minimum, your balance could continue growing exponentially as a result of compounding interest. This is how people get trapped in a "debt cycle."
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.
This rule is based on the principle of compounding interest and suggests that if you invest in a mutual fund with a 12 per cent annual return, your investment will double approximately every 8 years. After the first doubling, it will double again in the next 4 years, and then a final time in the subsequent 3 years.
Compound interest is better for you if you're saving money in a bank account or being repaid for a loan. If you're borrowing money, you'll pay less over time with simple interest. Simple interest really is simple to calculate.
Most investors are familiar with the magic of compounding interest but they often fail to realize that when the portfolio loses money, the math of compounding works against them.
Compound interest causes principal to grow exponentially over time. In the case of invested assets, it is a powerful tool to build wealth. However, for those who pay compound interest on loans, it can dig a deep hole that may be difficult to escape.
The Bottom Line. Safe assets such as U.S. Treasury securities, high-yield savings accounts, money market funds, and certain types of bonds and annuities offer a lower risk investment option for those prioritizing capital preservation and steady, albeit generally lower, returns.
The Rule of 72 applies to compounded interest rates and is reasonably accurate for interest rates that fall in the range of 6% and 10%.
Alternatively you can calculate what interest rate you need to double your investment within a certain time period. For example if you wanted to double an investment in 5 years, divide 72 by 5 to learn that you'll need to earn 14.4% interest annually on your investment for 5 years: 14.4 × 5 = 72.
Einstein also said that “If people really understood the Rule of 72 they would never put their money in banks.” Suppose that a 10-year-old has $500 to invest. She puts it in her savings account that has a 1.75% annual interest rate.
To answer the question of how to double my money quickly, simply invest in a portfolio of investment options like ULIPs, mutual funds, stocks, real estate, corporate bonds, Gold ETFs, National Savings Certificate, and tax-free bonds, to name a few.
For other compounding frequencies (such as monthly, weekly, or daily), prospective depositors should refer to the formula below. Hence, if a two-year savings account containing $1,000 pays a 6% interest rate compounded daily, it will grow to $1,127.49 at the end of two years.
This means, not only will you earn money on the principal amount in your account, but you will also earn interest on the accrued interest you've already earned. The idea of compound interest (as compared to simple interest) is fundamental to investing because it can ultimately lead to a greater return in your account.
Susan invested $50,000 and Bill invested $150,000. Why did Susan have a higher balance at the age of 65? Susan had a larger balance at the age of 65 because she began saving at the age of 25 and continued for ten years, giving her investments 40 years to increase.
Bonds and bond funds
Bonds are usually seen as a good compounding investment. They are essentially loans one gives to a creditor, whether that's a company or government. That entity then agrees to give a specified yield in return for the investor buying the debt.
Simple interest is paid only on the money you deposit. So, for example, if you put $10,000 into a savings account that pays simple interest of 4% per year, after one year you'd earn $400 ($10,000 x 0.04), for a total of $10,400.
Compound interest makes your money grow faster because interest is calculated on the accumulated interest over time as well as on your original principal. Compounding can create a snowball effect, as the original investments plus the income earned from those investments grow together.
The 8-8-8 Rule would be the best place to start if you want to enhance your creativity. This rule states that you should dedicate eight hours to sleep, eight hours to work, and eight hours to leisure activities. By following this schedule, your body will be ready to focus on creative tasks when it is time for leisure.
The 15-15-15 rule suggests investing 15% of your income for 15 years in a mutual fund with 15% annual returns. Compounding is the process of reinvesting earnings to generate more returns. The longer you stay invested, the greater the compounding effect. =
