What is the ‘Rule of 70’ in finance?
When it comes to personal finance, understanding the impact of inflation on our money is crucial. Inflation can erode the purchasing power of our hard-earned cash, making it essential to plan and invest wisely. One simple yet effective tool to estimate the future buying power of money is the “Rule of 70.” In this blog post, we’ll delve into the details of the Rule of 70, its significance, and how it can help you make informed financial decisions.
The Rule of 70 is a straightforward formula used to calculate the number of years it takes for the value of money to halve due to inflation. The formula is simple: divide 70 by the inflation rate. The result shows how many years it will take for the rupee’s value to lose half of its purchasing power. For instance, if the inflation rate is 4%, dividing 70 by 4 gives us 17.5 years. This means that if something costs ₹100 today, it will cost approximately ₹200 in 17.5 years, effectively reducing the rupee’s purchasing power by half.
To illustrate this concept further, let’s consider a few examples. Suppose the inflation rate is 5%. Using the Rule of 70, we divide 70 by 5, which gives us 14 years. This means that if you have ₹100 today, its value will be equivalent to ₹50 in 14 years, assuming a constant inflation rate of 5%. Similarly, if the inflation rate is 3%, dividing 70 by 3 gives us 23.33 years. This implies that the value of ₹100 today will be equivalent to ₹50 in approximately 23.33 years.
The Rule of 70 serves as a valuable reminder of the impact of inflation on our money. It highlights the importance of investing in assets that can keep pace with or outperform inflation, such as stocks, mutual funds, or real estate. By doing so, we can protect our purchasing power and ensure that our money retains its value over time.
In addition to the Rule of 70, there are other essential money rules that can help you achieve financial security. For example, the Rule of 72 is a similar formula used to estimate the number of years it takes for an investment to double in value, based on the interest rate it earns. Another important rule is the 20x life insurance rule, which suggests that you should have life insurance coverage equal to 20 times your annual income. These rules, including the Rule of 70, can provide a solid foundation for your financial planning and help you make informed decisions about your money.
In conclusion, the Rule of 70 is a simple yet powerful tool for estimating the future buying power of money. By dividing 70 by the inflation rate, you can determine how many years it will take for the rupee’s value to halve. This knowledge can help you plan and invest wisely, protecting your purchasing power and ensuring that your money retains its value over time. Remember to consider other essential money rules, such as the Rule of 72 and the 20x life insurance rule, to achieve financial security and peace of mind.
