💬 Frequently Asked Questions (FAQ) – Compound Interest Calculator

❓ What is compound interest?

Compound interest is the interest earned on both your initial principal and the interest already added from previous periods.
It helps your money grow faster because you earn “interest on interest.”

❓ How is compound interest calculated?

The formula for compound interest is:
A = P × (1 + r/n)^(n×t)
Where:

A = Final amount
P = Principal amount
r = Annual interest rate (in decimal form)
n = Number of compounding periods per year
t = Number of years

Our online calculator automatically applies this formula for you.

❓ What is the difference between simple and compound interest?

Simple interest grows linearly — you only earn interest on the original amount.
Compound interest grows exponentially — you earn interest on both the principal and accumulated interest.

This means compound interest can grow your money much faster over time.

❓ How often does interest compound?

Interest can compound:

Annually (1x per year)
Semi-annually (2x)
Quarterly (4x)
Monthly (12x)
The more frequently it compounds, the more interest you earn.

❓ Why is compound interest important for savings and investments?

Because it’s the foundation of long-term wealth building. Even small regular savings can grow into large sums over time due to the compounding effect. That’s why it’s used in fixed deposits, retirement plans, and mutual funds.

❓ Can I calculate compound interest in different currencies?

Yes ✅ — our calculator supports USD, PKR, EUR, GBP, and INR. The formula stays the same; only the currency symbol and formatting change.
