💰 Compound Interest Calculator – Your Smart Investment Planning Tool

Looking for a quick and accurate way to calculate your investment growth over time? Our Compound Interest Calculator is the ultimate tool to help you plan your financial future. Whether you’re saving for retirement, education, or long-term wealth, this tool will help you see how your money grows using the power of compounding.


📈 What is Compound Interest?

Compound interest means you earn interest not just on the principal amount, but also on the interest that accumulates over time. Unlike simple interest, where only the principal earns interest, compound interest multiplies your earnings faster.

This is what makes compound interest one of the most powerful tools for wealth creation. The more frequently your interest is compounded, the faster your money grows.

  3. Add the Annual Interest Rate in percentage.

  4. Set the Investment Period (in years).

  5. Choose Compounding Frequency: Monthly, Quarterly, Half-Yearly, or Yearly.

  6. (Optional) Add Monthly Deposits to see how regular contributions boost your savings.

Once you enter the data, the calculator instantly computes your future investment value using the standard compound interest formula.


🧠 Formula Used:

ini
A = P(1 + r/n)^(nt) + [D × ((1 + r/n)^(nt) - 1) ÷ (r/n)]

Where:

  • A = Future Value

  • P = Principal Amount

  • r = Annual Interest Rate (as decimal)

  • n = Compounding Periods per Year

  • t = Time in Years

If you invest ₹1,00,000 at an interest rate of 7.5% per annum for 10 years, compounded monthly, with an optional ₹2,000 monthly deposit — the calculator will show your total future value and interest earned.
