What Is The Rule of 72
The rule of 72 is a simple way to calculate how long it will take for an investment to double, given a fixed annual rate of return. To use the rule, simply divide 72 by the annual rate of return. The resulting number is the approximate number of years it will take for the investment to double.
For example, earning an 8% annual return on your investment will take approximately 9 years for your investment to double (72/8 = 9). Likewise, if you are earning a 12% annual return on your investment, it will take approximately 6 years for your investment to double (72/12 = 6).
The rule of 72 is a rough estimate and does not consider compounding, which can significantly impact the length of time it takes for an investment to double.
Compounding occurs when the interest earned on an investment is reinvested so that the next period’s interest is earned on both the original and reinvested interest. This has the effect of accelerating the growth of the investment.
The rule of 72 is a useful tool for estimating how long it will take for an investment to grow, but it is important to remember that it is only an estimate. For a more accurate calculation, you can use a compound interest calculator.

What Are Three Things The Rule Of 72 Can Determine?
The rule of 72 can be used to estimate the following:
- Given a fixed annual rate of return, how long will it take for an investment to double.
- The approximate number of years it will take for an investment to double.
- That compounding can significantly impact the length of time it takes for an investment to double.
How Deferred Annuities Can Use The Rule For Retirement Savings
Deferred annuities can use the rule of 72 to estimate how long it will take for the investment to double. Given a fixed annual rate of return, the deferred annuity will grow at a set rate. The rule of 72 can be used to help estimate how long it will take for this growth to occur so that retirees can plan accordingly.
For example, if a deferred annuity has an annual return of 6%, it will take approximately 12 years for the investment to double (72/6 = 12). This means that if a retiree wants their money to last 20 years in retirement, they would need to start withdrawing from the account after 8 years (20-12 = 8).
Retirees should remember that the rule of 72 is a rough estimate and does not consider triple-compounding from the annuity. This means that the actual length of time it will take for the investment to double could be less or more than what is estimated using the rule.
Despite this, the rule of 72 can still be a helpful tool for retirement planning. It can give retirees a general idea of how long their savings will last and help them decide when to start withdrawing from their accounts.
How Does The Rule Of 72 Work With Inflation?
Inflation is the rate at which the prices of goods and services increase over time. The rule of 72 can be used to estimate how long it will take for the price of goods and services to double, given a fixed annual inflation rate. To use the rule, simply divide 72 by the inflation rate. The resulting number is the approximate number of years it will take for the prices of goods and services to double.
For example, if the inflation rate is 3%, it will take approximately 24 years for the prices of goods and services to double (72/3 = 24). Likewise, if the inflation rate is 6%, it will take approximately 12 years for the prices of goods and services to double (72/6 = 12).
The rule of 72 is a useful tool for estimating how long it will take for the prices of goods and services to double, but it is important to remember that it is only an estimate. Your actual results may vary.
What Are The Disadvantages Of Using The Rule Of 72?
- One potential disadvantage of using the rule of 72 is that it does not consider compounding, which can significantly impact the time it takes for an investment to double.
- Another potential disadvantage of using the rule of 72 is that it is only an estimate. Your actual results may vary.
- Finally, the rule of 72 does not account for inflation, which can erode the purchasing power of your investment over time.
- Despite its potential disadvantages, the rule of 72 is a useful tool for estimating how long it will take for an investment to grow or for the prices of goods and services to double.
Rule Of 72 Calculator
The rule of 72 is a simple way to calculate how long it will take for an investment to double. All you need to do is divide 72 by the annual rate of return. For example, if you’re earning a 6% annual return, it will take 72/6, or 12 years, for your investment to double.
The rule of 72 is a valuable tool because it can help you understand the impact of compound interest. With compound interest, your investment grows over time and earns interest on the interest that has already been earned. As a result, investments can grow much more quickly than most people realize. The rule of 72 is a helpful way to estimate how long it will take for an investment to double and to harness the power of compound interest.
