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 rising costs of goods and services can erode the purchasing power of our savings, making it essential to plan and invest wisely. One useful tool that can help us estimate the future buying power of money is the ‘Rule of 70’. In this blog post, we will delve into the concept of the ‘Rule of 70’, its significance, and how it can be applied in personal finance.
The ‘Rule of 70’ is a simple yet effective method used to 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, and the result will show 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 would cost approximately ₹200 in 17.5 years, assuming a constant inflation rate of 4%. In other words, the rupee would lose half of its purchasing power in about 17.5 years.
To understand the significance of the ‘Rule of 70’, let’s consider an example. Suppose you have saved ₹10,000 in a savings account that earns a nominal interest rate of 4% per annum. Over time, the purchasing power of your savings will decrease due to inflation. If the inflation rate is 4%, the ‘Rule of 70’ suggests that the value of your savings will halve in approximately 17.5 years. This means that the ₹10,000 you saved today will have the same purchasing power as ₹5,000 in 17.5 years. This example highlights the importance of considering inflation when planning for long-term financial goals.
The ‘Rule of 70’ has significant implications for investment decisions. When inflation is high, the value of money decreases rapidly, making it essential to invest in assets that can keep pace with inflation. For instance, if the inflation rate is 7%, the ‘Rule of 70’ suggests that the value of money will halve in approximately 10 years. In such a scenario, investing in fixed deposits or savings accounts may not be the best option, as the returns may not be sufficient to keep pace with inflation. Instead, investors may consider investing in assets such as stocks, mutual funds, or real estate, which have the potential to generate higher returns and keep pace with inflation.
Another important aspect of the ‘Rule of 70’ is its relationship with interest rates. When interest rates are high, the ‘Rule of 70’ suggests that the value of money will decrease more rapidly. This is because high interest rates often accompany high inflation, which can erode the purchasing power of money. In such scenarios, investors may need to reconsider their investment strategies and opt for assets that can generate higher returns to keep pace with inflation.
In addition to its application in investment decisions, the ‘Rule of 70’ can also be used to estimate the impact of inflation on retirement savings. For instance, if you are planning to retire in 20 years and expect to live off your savings for 20 years after retirement, you will need to consider the impact of inflation on your savings. Using the ‘Rule of 70’, you can estimate how much your savings will be worth in 20 years and plan accordingly. This can help you make informed decisions about your retirement savings and ensure that you have sufficient funds to maintain your standard of living after retirement.
In conclusion, the ‘Rule of 70’ is a simple yet powerful tool that can help individuals estimate the future buying power of money. By dividing 70 by the inflation rate, we can determine how many years it will take for the value of money to halve due to inflation. This knowledge can be used to make informed investment decisions, plan for retirement, and ensure that our savings keep pace with inflation. As the famous saying goes, “inflation is a silent thief that steals the purchasing power of our money.” The ‘Rule of 70’ can help us understand the impact of inflation and make smart financial decisions to secure our financial future.
