What is the ‘Rule of 70’ in Finance?
As individuals, we often struggle to understand the impact of inflation on our hard-earned money. The value of money can fluctuate over time, and it’s essential to have a clear understanding of how inflation can erode the purchasing power of our savings. One useful tool in finance that can help 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 be applied to make informed financial decisions.
The ‘Rule of 70’ is a simple yet effective formula that helps estimate the number of years it takes for the value of money to halve due to inflation. The formula is straightforward: divide 70 by the inflation rate to determine the number of years it will take for the value of money 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 at an inflation rate of 4%, something that costs ₹100 today would cost approximately ₹200 in 17.5 years, resulting in the rupee losing half of its purchasing power.
To illustrate this concept further, let’s consider a few examples. If the inflation rate is 5%, dividing 70 by 5 gives us 14 years. This means that at an inflation rate of 5%, something that costs ₹100 today would cost approximately ₹200 in 14 years. Similarly, if the inflation rate is 3%, dividing 70 by 3 gives us 23.33 years, indicating that it would take approximately 23.33 years for the value of money to halve at an inflation rate of 3%.
The ‘Rule of 70’ is an essential tool for individuals to understand the impact of inflation on their savings and investments. It helps us appreciate the importance of investing our money wisely to stay ahead of inflation. By investing in assets that offer returns higher than the inflation rate, we can ensure that our purchasing power is not eroded over time. For example, if we invest in a fixed deposit that offers an interest rate of 6%, and the inflation rate is 4%, our investment will grow at a rate of 2% above inflation, helping us maintain our purchasing power.
In addition to the ‘Rule of 70’, there are other important money rules that individuals should be aware of to achieve financial security. For instance, the ‘Rule of 72′ is a formula that estimates the number of years it takes for an investment to double in value based on the interest rate it earns. Similarly, the ’50/30/20 rule’ is a guideline that suggests allocating 50% of our income towards necessary expenses, 30% towards discretionary spending, and 20% towards saving and debt repayment.
In conclusion, the ‘Rule of 70’ is a valuable tool in finance that helps estimate the future buying power of money. By understanding how inflation can erode the value of our savings, we can make informed decisions about our investments and ensure that our purchasing power is not compromised over time. As individuals, it’s essential to be aware of the various money rules that can help us achieve financial security, including the ‘Rule of 70’, ‘Rule of 72′, and ’50/30/20 rule’. By applying these rules and formulas, we can take control of our finances and build a secure financial future.
