The Magic of Compound Interest Explained
Albert Einstein supposedly called compound interest the "eighth wonder of the world," and for good reason! Compound interest is when the interest you earn on your money starts earning interest of its own.
For example, if you invest $1,000 at a 10% annual return, you earn $100 in the first year. In the second year, you don't just earn 10% on your original $1,000; you earn 10% on $1,100! Over 10, 20, or 30 years, this snowball effect creates massive wealth, especially if you continue making regular monthly contributions.
Our calculator uses the standard financial formula for compound interest, compounding your monthly contributions automatically to give you the most accurate real-world projection possible.

Frequently Asked Questions (FAQs)
What is a good annual interest rate to use?
If you are investing in a standard high-yield savings account, your rate might be between 3% to 5%. If you are investing in broad stock market index funds (like the S&P 500), financial advisors often suggest using an estimated average return of 7% to 10% per year.
Does this tool calculate taxes or inflation?
No, this calculator provides a gross estimate of your investment growth. It does not account for capital gains taxes or the annual inflation rate, which can vary wildly depending on your country and local economy.
Is this the same as an SIP Calculator?
Yes! A Systematic Investment Plan (SIP) calculator works on the exact same principles of compounding monthly contributions. You can use this tool to calculate your mutual fund SIP returns perfectly.
