Introduction to Compound Interest Calculator
A Compound Interest Calculator is a powerful financial tool that helps you calculate how your money grows over time when interest is added to the principal as well as previously earned interest. This calculator is essential for anyone planning long-term investments, savings, or wealth creation.
What is Compound Interest?
Compound interest means earning interest on both your initial principal and on the accumulated interest from previous periods. This creates exponential growth for savings and investments.
Compound Interest Formula
The standard formula for compound interest is:
A = P (1 + r/n)^(n × t)
- A = Future Value
- P = Principal Investment
- r = Annual Interest Rate (decimal)
- n = Number of compounding periods per year
- t = Time (years)

Example
Suppose you invest ₹500,000 at 7.5% annual interest, compounded quarterly, for 10 years. This calculator will display the future value and total interest earned.
Q: How does compounding frequency affect my investment?
A: The more frequently interest is compounded, the higher the total returns. For instance, monthly compounding gives higher returns than yearly compounding at the same rate.
Q: Is compound interest better than simple interest?
A: Yes, because compound interest accumulates on both principal and past interest, while simple interest grows only on the principal.
