Compound Interest Calculator – Calculate Investment Growth & Returns

A compound interest calculator helps you estimate how your investment grows over time by earning interest on both your initial principal and accumulated interest. This powerful concept, known as compounding, allows your money to grow exponentially over time. Whether you are saving for retirement, investing in mutual funds, or planning long-term wealth, this calculator gives you a clear projection of your future returns.

By using this compound interest calculator online, you can easily visualize how small investments turn into large amounts with time and consistency.

What is Compound Interest?

Compound interest is the process of earning interest on both your initial investment and the interest already earned. Unlike simple interest, where you earn interest only on the principal, compounding accelerates growth over time.

This is why compound interest is often called the “power of compounding” in finance.

Compound Interest Formula

The formula used in this calculator is:

A = P (1 + r/n)^{(n × t)}

• P = Principal (initial investment)
• r = Annual interest rate
• n = Number of times interest is compounded per year
• t = Time in years
• A = Final amount

This formula helps calculate how your investment grows over time with compounding.

Example of Compound Interest

Let’s understand with a simple example:

• Investment = ₹1,00,000
• Interest rate = 10% annually
• Time = 10 years
• Compounding = Yearly

After 10 years:

• Total value ≈ ₹2.5–2.6 lakh
• Interest earned ≈ ₹1.5 lakh+

This shows how compounding significantly increases your wealth over time.
