What is an EMI?
EMI stands for Equated Monthly Instalment — the fixed monthly amount you pay to repay your loan. Each EMI payment consists of two components: a portion goes towards repaying the principal amount, and the rest covers the interest charged for that month. Over time, the principal component increases and the interest component decreases.
The EMI Formula
The standard formula for calculating EMI is:
EMI = P × r × (1 + r)^n / [(1 + r)^n – 1]
Where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the loan tenure in months.
Example Calculation
If you take a home loan of ₹50 Lakh at 8.5% per annum for 20 years (240 months), your monthly EMI would be approximately ₹43,391. Over the tenure, you would pay a total of ₹1,04,13,840, of which ₹54,13,840 is interest.
Factors That Affect Your EMI
- Principal Amount: Higher the loan, higher the EMI
- Interest Rate: Even a 0.5% change significantly impacts your EMI
- Loan Tenure: Longer tenure means lower EMI but higher total interest paid
How to Reduce Your EMI
There are three main ways to reduce your EMI: negotiate a lower interest rate (improve your CIBIL score for this), extend your loan tenure, or make a larger down payment to reduce the principal. Part-prepayments during the loan tenure can also reduce either your EMI or the remaining tenure.
Understanding Amortisation
In the early years of a loan, a larger share of your EMI goes toward interest and a smaller share toward principal. This gradually reverses over time. This is why prepaying a loan early in the tenure saves the most interest.
