Compound Interest Calculator
Calculate compound interest based on principal, interest rate, time, and compounding frequency.
Introduction
Compound interest allows your money to grow exponentially — interest is calculated on both the original amount and previously accumulated interest.
Compound Interest Formula
A = P × (1 + r/n)nt
- A = Final Amount
- P = Principal Amount
- r = Annual Interest Rate
- n = Compounding per Year
- t = Time in Years
How to Use the Calculator
- Enter the starting amount (Principal).
- Enter the annual interest rate.
- Enter the time period in years.
- Enter compounding frequency (e.g., 12 = monthly).
- Click Calculate to see results.
Examples
- ₹10,000 at 8% for 10 years (annual) → ₹21,589.25
- ₹50,000 at 6% for 15 years (monthly) → ₹120,712.60
- ₹1,00,000 at 12% for 20 years (quarterly) → ₹9,89,997
