Understanding the Time Value of Money
This calculator allows you to solve for four standard financial variables: Future Value (FV), Present Value (PV), Interest Rate, and Periods. Provide the remaining inputs, including periodic payment when applicable, to analyze loans, investments, and personal wealth growth.
The Four Variables
- N (Periods): The total number of payment periods (usually months or years).
- Annual Rate (%): The annual interest rate percentage.
- Present Value (PV): The current value of a sum of money or the initial principal.
- Future Value (FV): The value of an investment or the remaining balance at the end of the term.
How It Works
This tool uses standard financial mathematical formulas to determine the relationship between your current savings and future goals. For accuracy, it assumes payments (PMT) and initial principal (PV) are investments (outflows), while the final result (FV) is the money you receive (inflow).
Common Use Cases
- Solving for Future Value: Determine how much your current savings and monthly contributions will be worth in 10 or 20 years.
- Solving for Present Value: Figure out how much you need to invest today to reach a specific goal in the future.
- Solving for Interest Rate: Calculate the return you need on your investments to reach your goals.
- Solving for Periods: Find out how long it will take to reach a savings target.
