About Compound Interest Calculator
Compound Interest is the result of interest being calculated on the principal plus accumulated interest. Albert Einstein famously called it the 'eighth wonder of the world'. It makes your money grow exponentially over time.
How it works?
A = P (1 + r/n)^(nt)- A = Future Value
- P = Principal Amount
- r = Annual Interest Rate (decimal)
- n = Number of times interest is compounded per unit t
- t = Time

Frequently Asked Questions
How often should interest compound?
The more frequent the compounding (e.g., daily vs annually), the higher the returns.
Compound vs Simple Interest?
Simple interest is calculated only on the principal. Compound interest is calculated on principal + accumulated interest, leading to much faster growth.
What is the Rule of 72?
It's a shortcut to estimate doubling time. Divide 72 by your interest rate (e.g., 72 / 12% = 6 years to double money).
