Investment Calculator

Estimate how your investments can grow over time with compound interest and regular contributions.

What Is an Investment Calculator?

An investment calculator helps you estimate the future value of your investments based on your initial amount, monthly contributions, annual interest rate, and time period. Whether you’re planning for retirement, education, or long-term savings, this tool allows you to understand how your money can grow over time.

How the Investment Calculator Works

This calculator uses the compound interest formula to project future investment value. By entering your initial investment, monthly contribution, annual interest rate, and investment duration, you can instantly see your potential returns. Compound interest means that your returns grow not only on the principal but also on accumulated interest.

Formula Used

The formula for compound interest with regular contributions is:
FV = P(1 + r/n)nt + PMT × [(1 + r/n)nt − 1] / (r/n)
Where: – FV = Future Value – P = Principal amount – r = Annual interest rate – n = Compounding periods per year – t = Number of years – PMT = Regular contribution

Example Calculation

If you invest $5,000 initially, contribute $200 monthly, with a 6% annual return for 10 years, your total investment would be $29,000. Your estimated return would grow to approximately $39,700, resulting in a profit of nearly $10,700 from interest alone.
