Calculate Compound Interest
This is an estimated calculation. Actual returns may vary depending on the investment product, rate changes, and other conditions.
What is Compound Interest?
Compound interest is interest calculated on both the original principal amount and the interest already earned. This means your money can grow faster over time because you earn interest on interest.
How Does This Compound Interest Calculator Work?
This calculator uses your principal amount, annual interest rate, investment duration, and compounding frequency to estimate the final amount you may receive at the end of the selected period.
Compound Interest Formula
The compound interest amount is calculated using the following formula:
- A = Final amount
- P = Principal amount
- r = Annual interest rate
- n = Number of times interest is compounded per year
- t = Time period in years

Frequently Asked Questions
What is the difference between simple interest and compound interest?
Simple interest is calculated only on the principal amount. Compound interest is calculated on the principal amount plus the interest already earned.
Is higher compounding frequency better?
Generally, yes. More frequent compounding can increase the final amount, although the difference may be small depending on the rate and time period.
Can compound interest help in long-term wealth creation?
Yes. Compound interest becomes more powerful over longer periods because the interest earned also starts earning interest.
Are compound interest returns guaranteed?
It depends on the product. Fixed deposits may offer fixed returns, while market-linked investments can vary.
