Present Value vs Future Value Calculations
Present value (PV) and future value (FV) calculations are essential tools for understanding how money values change over time. Present value determines what a future sum of money is worth in today's dollars, while future value calculates what current money will be worth at a specific point in the future.
These calculations consider key variables including the principal amount, interest rate, compounding frequency, and time period. The compound interest formula demonstrates how money grows exponentially rather than linearly, highlighting the power of starting investments early and allowing time for growth.
Practical applications include evaluating whether to take a lump sum payment or annuity, comparing investment options with different time horizons, and determining how much to save for future goals like retirement or education expenses.
