Compound Interest in Excel

Compound interest represents a fundamental concept in finance, essential for calculating the growth of investments and savings over time. This interest type accounts for both the initial amount invested or borrowed (the principal) and the interest that accumulates over periods of investment. Excel's capabilities in dealing with compound interest calculations make it an indispensable tool for financial analysis and planning.

The formula used in Excel for compound interest calculations, = P(1+R/T)^(NT), along with the FV function, simplifies the process of understanding how one's investments will grow under different scenarios. For example, adjusting the period of compounding from annual to quarterly or monthly can significantly affect the outcome, showcasing the power of compound interest over time.
