This tool helps you find the interest rate needed to achieve a desired future value given a present value.
How to Use the Interest Rate Calculator
Enter the Present Value (PV), Future Value (FV), and the Number of Periods (n) into the appropriate fields and click “Calculate”. This calculator will compute the interest rate (r) required to grow the Present Value to the Future Value over the specified number of periods.
Detailed Explanation:
The formula used for this calculation is derived from the compound interest formula:
FV = PV * (1 + r)^n
Rearranging to solve for r, we get:
r = (FV / PV)^(1/n) - 1
This interest rate is then converted to a percentage and rounded to six decimal places for precision. The displayed results include the entered parameters and the computed interest rate.
Limitations:
This calculator assumes a consistent interest rate over all periods. It does not account for varying interest rates, fees, taxes, or any other potential real-world considerations that might affect the actual rate.
