🔢 Compound Interest Calculator: Easily Grow Your Wealth Over Time

A compound interest calculator helps you estimate how much your money will grow over time when interest is added not just to the principal amount but also to the interest already earned. It’s a smart way to plan your savings, investments, and financial goals.

📌The Formula to Calculate Compound Interest:

Compound interest is calculated using the formula:
A = P (1 + r/n)^(nt)

Where:

  • A = Final amount

  • P = Initial principal (starting amount)

  • r = Annual interest rate (in decimal)

  • n = Number of times interest is compounded per year

  • t = Time (in years)

This formula helps you understand how money grows faster when interest is compounded — for example, quarterly or monthly.

❓ Frequently Asked Questions (FAQs)

What is compound interest?

Compound interest is the interest calculated on both the initial principal and the interest accumulated from previous periods. It helps your money grow faster compared to simple interest.

Yes, compound interest is better for long-term investments because it earns “interest on interest,” resulting in exponential growth over time.

It depends on the investment type. Common compounding frequencies include annually, semi-annually, quarterly, monthly, and daily. The more frequent the compounding, the higher the final return.

Yes, this calculator can be used to estimate returns on SIPs or mutual funds by entering monthly contributions and adjusting the compounding frequency.

Early withdrawal may reduce the compounding effect, and some investments may also have penalties or reduced returns for early exit.
