Rule of 72: Easily estimate how quickly your investment doubles
What's the story
The Rule of 72 is a simple formula to estimate the number of years it would take to double an investment at a fixed annual rate of return.
By dividing 72 with the expected annual interest rate, investors can quickly gauge how long their money will take to grow twofold.
This rule comes especially handy for those looking to make informed decisions about savings/investments without complex calculations.
Formula basics
Understanding the formula
The Rule of 72 is simply dividing the number 72 by the annual interest rate in percentage.
For instance, if your investment is giving a 6% annual return rate, dividing 72 by six gives you 12 years - the time it will take for your investment to double.
This simple calculation comes in handy for investors to plan their financial goals.
Real-world uses
Practical applications
Investors frequently employ the Rule of 72 for quick comparisons of various investment opportunities in the market.
Be it stocks, bonds, or savings accounts, this rule offers a ballpark figure that assists in decision-making processes.
Additionally, it acts as a yardstick for assessing whether certain investments fulfill personal financial goals over time.
Potential drawbacks
Limitations and considerations
While helpful, the Rule of 72 comes with limitations. It assumes a constant interest rate and does not account for taxes or fees that might affect returns.
Also, it may not be accurate for very high or low interest rates due to its simplicity.
Investors should consider these factors when using this rule as part of their broader financial strategy.
