Summary

How to Use the Interest Calculator

Our advanced Interest Calculator is a versatile tool designed to help you handle various financial calculations in one place. Whether you are an investor looking to project your wealth growth or a borrower planning loan repayments, this tool covers it all.

1. Investment (Compound)

Use this mode for Savings accounts, SIPs, or Fixed Deposits. It uses the compound interest formula A = P(1 + r/n)^(nt) to show how your money grows over time with optional monthly contributions.

2. Loan Calculator (EMI)

Planning to take a Home Loan or Car Loan? Switch to the "Loan" tab. This amortized calculator computes your monthly EMI and total interest payable using the standard banking formula.

3. Simple Interest

Best for short-term non-compounding loans or basic educational calculations. It uses the classic formula SI = (P × R × T) / 100.
