How to Use the Interest Calculator
This interest calculator helps you to understand how your investments will grow over time with compound interest. To use the calculator:

How It Calculates Results
The calculator works by applying the compound interest formula iteratively for each year. The formula used is:
Future Value = Start Balance + (Start Balance * (Annual Interest Rate / 100)) + Annual Contribution
The results table shows the balance at the start of each year, the interest earned during the year, and the balance at the end of each year.
Limitations
The calculator assumes a fixed annual interest rate and doesn’t account for taxes or fees. Also, it assumes that annual contributions are made at the end of each year. For more accurate financial planning, consider consulting a financial advisor.
