Compounding Interest Concepts and Calculations

This video tutorial introduces the concept of compounding interest, explaining how it works and its financial implications. It covers the formula for calculating compounded interest, including the roles of principal, rate, and compounding frequency. An example is provided using semi-annual compounding, and a comparison is made with daily compounding to show the impact of different frequencies. The tutorial concludes with a demonstration of graphing the exponential growth of compounded interest over time.
