Review Questions
How does the principal amount influence the calculation of both simple and compound interest?
The principal amount acts as the base figure for calculating both simple and compound interest. In simple interest calculations, the formula uses the principal to determine how much interest accrues over a specified period. For compound interest, the principal not only determines initial interest but also serves as a foundation for future interest calculations on previously accrued amounts, leading to growth in total investment value over time.
Discuss how changes in the principal amount can affect future financial decisions related to investments or loans.
Changes in the principal amount can significantly impact future financial decisions. If an investor increases their principal amount, they can expect higher returns due to greater accrued interest over time. Conversely, for loans, a higher principal means increased total repayments. This dynamic makes it crucial for individuals to consider their principal amounts carefully when planning their finances, as it influences their overall financial health and decision-making.
