How to Use This Calculator

  3. Change one input at a time so you can see what actually moves the result.
  4. Compare at least two scenarios, such as conservative and optimistic assumptions.

How the Calculation Works

The calculator uses the EMI formula, then shows how repayment gradually shifts from interest to principal.

Formula Used

Each period interest = outstanding balance x monthly rate; principal repaid = EMI - interest.

Input Field Explanation

Loan Amount

Enter the main amount used for this calculation. For best results, use the actual value you want to plan with.

Interest Rate (%)

Enter the annual percentage rate. Use a realistic rate rather than an overly optimistic one.

Tenure (Years)

Enter the number of years for the estimate. A longer period can change the result significantly.

Example Calculation

In early years, a larger part of EMI often goes toward interest. Later, principal repayment becomes faster.

Early years usually carry more interest, while later years repay principal faster. Replace the sample values with your own numbers before using the estimate for planning.
