Loan Calculators and Amortization Schedules
A loan calculator is a financial tool used to compute the Equated Monthly Instalment (EMI) payable on a loan, based on key parameters such as the loan amount, interest rate, and repayment tenure. In parallel, a loan amortization schedule provides a detailed breakdown of each loan payment over time, delineating the proportion allocated towards interest and principal reduction. Together, these tools offer borrowers critical insight into their loan repayment structure.
Loan Calculator
Purpose:
A loan calculator determines the monthly installment (EMI) required to repay a loan by factoring in the principal amount, applicable interest rate, and total duration of the loan.
Formula:
P×R×(1+R)^N / (1+R)^N-1
Where:
- P = Principal amount
- R = Monthly interest rate (annual interest rate divided by 12 and expressed as a decimal)
- N = Total number of monthly installments
- Illustrative Example:
Suppose a borrower avails a loan of ₹50 lakhs at an annual interest rate of 9%, repayable over a tenure of 240 months. Using the EMI formula, the monthly installment would be approximately ₹44,986. - To explore this in detail, refer to the article: “Illustration of How Your Loan EMI is Calculated.”
Loan Amortization Schedule
Purpose:
An amortization schedule is a table that outlines each EMI payment throughout the loan tenure, dividing it into interest and principal components. It shows how the outstanding balance reduces with each installment.
Key Components:
- Period (e.g., month number)
- Opening balance
- EMI amount
- Interest component
- Principal component
- Closing balance
Payment Structure:
In the initial stages of repayment, a greater portion of the EMI is applied towards interest. As the loan matures, the principal repayment gradually increases, while the interest portion decreases.
Illustrative Example:
For a car loan, the amortization schedule would detail how each monthly installment is split between interest charges and principal repayment, illustrating the gradual reduction of the loan balance.
Calculation Method:
To calculate the principal and interest for a specific month:
- Multiply the outstanding principal by the interest rate.
- Divide the result by 12 to obtain the interest for the current month.
- Subtract the interest amount from the EMI to determine the principal repayment for that month.

Significance for Borrowers
- Transparency: Provides a clear understanding of how loan repayments are structured over time.
- Financial Planning: Enables borrowers to plan for prepayments, refinancing, or balance transfers.
- Tracking Progress: Helps in monitoring the reduction of outstanding loan balance and total interest paid.
