What Is Compound Interest?

Compound interest is the interest calculated on the original principal plus any accumulated interest from previous periods. This exponential growth makes compound interest a powerful tool for long-term wealth building.

The formula for compound interest is:

A = P × (1 + r/n) ^ (nt)

Where:

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

To simplify this, our calculator handles everything behind the scenes. Just enter your amount, rate, duration, and frequency.

Want to calculate how much a one-time investment of ₹1,00,000 will be worth in 20 years at 10% interest compounded annually? Our calculator will show you instantly.
