Everyone who takes a loan—whether it’s for a home, car, education, or business—deals with monthly repayments called EMIs. But how is this EMI calculated? That’s where the amortization formula comes in. It helps break down each EMI into two parts—interest and principal—so you can see exactly how your loan gets paid off over time.The amortization formula is a mathematical equation that helps calculate the monthly payment needed to pay off a loan over a specific period at a given interest rate. You use this formula to know your EMI and to track how much interest you’ll pay overall. It answers the core question: How much do I pay monthly, and how does that amount reduce my loan balance? Using the formula correctly helps you choose better loan terms, manage your EMI without stress, and avoid overpaying on interest.
What Is Amortization?
Amortization is the process of repaying a loan gradually through scheduled monthly payments. Each EMI reduces the loan balance, which is called the principal, and pays off the interest charged by the lender. amortization is used because:
- It helps break large loan amounts into smaller, manageable payments.
- It allows for equal monthly outflows, making budgeting easier.
- It ensures that the borrower repays both the loan and interest in full by the end of the loan term.
What is Amortization Formula?
The amortization formula calculates your EMI (Equated Monthly Instalment). It tells you how much you must pay monthly to fully repay a loan over a certain period at a fixed interest rate.
The Formula:
| EMI = P × [r(1 + r)^n] / [(1 + r)^n – 1] |
Where:
- EMI = Monthly payment
- P = Loan principal
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (loan term in months)
Example: Loan- ₹5,00,000
Interest rate: 10% annually (0.10/12 = 0.0083 monthly)
Tenure: 60 months
Plug into the formula:
EMI=500000×0.0083(1+0.0083)^60(1+0.0083)^60−1
The EMI comes to approximately ₹10,624. This payment remains fixed, but its composition changes monthly.
