Using the Calculators
1. Future Value (FV)
Purpose: Calculate the future value of an investment based on periodic, constant payments and a constant interest rate.
Input Fields:
- Present Value (PV): The current value of the investment.
- Interest Rate (I/Y) (%): The annual interest rate (as a percentage).
- Number of Periods (N): The number of periods (years, months, etc.).
- Payment (PMT): The amount of any additional periodic payments.

- Enter Interest Rate (I/Y): Provide the annual interest rate (e.g., enter 5 for 5%).
- Enter Number of Periods (N): Specify how many periods the money will be invested for.
- Enter Payment (PMT): If you plan to add periodic payments, enter the amount here.
- Calculate: Click “Calculate FV” to see the future value.
- Result: The future value will be displayed below the form.
Example:
- PV: $1,000
- I/Y: 5%
- N: 10 years
