Compounding is a fundamental concept in finance that allows investors to calculate the future value of an investment based on its present value. It is a crucial tool for individuals and businesses to understand the potential growth of their investments over time. In this article, we will explore the multi-period formula for compounding a present value into a future value.
The multi-period formula accounts for the compounding effect over multiple time periods. It takes into consideration the interest rate or the rate of return and the number of periods over which the investment is compounded. By using this formula, investors can accurately calculate the future value of their investments.
One popular mathematical shortcut used to estimate the time it takes for an investment to double in value is the Rule of 72. This rule states that by dividing 72 by the interest rate or rate of return, one can approximate the number of periods it takes for the investment to double. For example, if the interest rate is 8%, it would take approximately 9 years for the investment to double in value.
