About This Tool
Amortization Calculator helps you understand EMI repayment and the principal-interest split. It is designed for loan and EMI planning and keeps the calculation simple enough to compare scenarios without confusion.

How to Use This Calculator
- Enter the values that match your real situation, not just ideal numbers.
- Review the main result first, then look at the supporting figures and chart where available.
- Change one input at a time so you can see what actually moves the result.
- 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.
