What is the ‘Rule of 70’ in finance?
The world of finance is filled with various rules and formulas that help individuals make informed decisions about their money. One such rule is the ‘Rule of 70’, which is used to estimate the future buying power of money. In simple terms, the Rule of 70 is a way to calculate how long it will take for the value of money to halve due to inflation. In this blog post, we will delve into the details of the Rule of 70, how it works, and its significance in personal finance.
The Rule of 70 is a straightforward formula that involves dividing 70 by the inflation rate to determine the number of years it will take for the value of money to decrease by half. 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, assuming an inflation rate of 4%. In other words, the rupee will lose half of its purchasing power in 17.5 years.
To understand the significance of the Rule of 70, let’s consider an example. Suppose you have ₹100,000 in a savings account that earns a nominal interest rate of 4%. Over time, the purchasing power of your money will decrease due to inflation. If the inflation rate is 4%, the Rule of 70 tells us that it will take approximately 17.5 years for the value of your money to halve. This means that in 17.5 years, your ₹100,000 will have the same purchasing power as ₹50,000 today.
The Rule of 70 is an essential concept in finance because it highlights the impact of inflation on the value of money. Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. As inflation rises, the purchasing power of money decreases, and the value of savings and investments declines. The Rule of 70 helps individuals understand the effects of inflation on their money and make informed decisions about investments and savings.
In addition to the Rule of 70, there are other important rules in finance that individuals should be aware of. For example, the Rule of 72 is a 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 individuals should have life insurance coverage equal to 20 times their annual income.
The Rule of 70 is also closely related to the concept of compounding. Compounding is the process of earning interest on both the principal amount and any accrued interest over time. When money is invested or saved, it can earn interest, which can then earn interest on itself, resulting in exponential growth. The Rule of 70 takes into account the effects of compounding, providing a more accurate estimate of the future value of money.
In conclusion, the Rule of 70 is a valuable tool in finance that helps individuals estimate the future buying power of money. By dividing 70 by the inflation rate, individuals can determine how many years it will take for the value of money to halve. This rule is essential in understanding the impact of inflation on savings and investments and making informed decisions about personal finance. As reported by ET, the Rule of 70 is a simple yet effective way to calculate the effects of inflation on the value of money.
