For many borrowers, EMI’s (equated monthly installment), Loan Tenure, Interest Rate are the most commonly used loan definitions – These three loan components are pivotal in establishing the total payment for borrowed funds, payment duration, total cost associated with the loan, the borrower must understand these three terms so that they may make educated choices when selecting the loan product, as well as to assist them in the general management of their budgets.

What does EMI mean and how does it work?

In essence, the term EMI means ‘Equal Monthly Instalment’. The EMI is the fixed dollar amount paid monthly throughout the life of the loan, until the loan is fully paid off. Payments can be made in manageable amounts (monthly) rather than repaying the entire amount borrowed at once.

Each EMI you pay comprises two components: 

Principal - the amount you borrowed originally

Interest - the cost charged by the lender for giving you the loan

In most fixed-rate loans, the EMI remains the same throughout the repayment period. This consistency helps borrowers estimate their monthly expenses without any surprises.

What determines your EMI?

The following three factors impact your EMI payment:

Principal Amount: The principal amount you will be borrowing. (Example: If you borrow a higher amount, your EMI will also be higher as you are paying off a larger loan).

Interest Rate: The percentage of interest you will pay to the lender for borrowing the funds. A higher interest rate will result in a higher EMI, and conversely, a lower interest rate will yield a lower EMI.

Loan Tenure: The timeframe you set for the complete repayment of the loan.

Longer tenure → Lower EMI, but more total interest paid

Shorter tenure → Higher EMI, but less total interest over time

There's a delicate balance between EMI and tenure, which holds the key to financial stability.

How EMI is calculated

Lenders use a standard formula to calculate EMI:

EMI = P × r × (1 + r)n / [(1 + r)n – 1]

Where:

P = Loan amount

r = Monthly interest rate (annual rate divided by 12)

n = Total number of monthly instalments

This formula ensures that EMI remains the same throughout the tenure, even as the distribution between principal and interest changes each month.

Interest vs Tenure — What's the right choice?

Interest and tenure have a significant relationship that determines the overall cost of a loan.

Longer Tenure

• Results in lower monthly EMI
• Makes the repayment easier with the monthly cash flow
• But it increases the total interest paid because the loan remains active longer

Shorter Tenure

• EMI goes up, putting additional load on the monthly income
• But it reduces the overall interest cost
• Helps to close the loan more quickly

Example:

A loan repaid in 10 years will have lower EMI than the same loan repaid in 5 years, but the total interest paid over the longer tenure will be far higher.

The tenure should be selected by the borrowers in accordance with their budget and not pose any long-term financial burden.

Throughout the life of your loan, even though your EMI does not change, the distribution of what you pay each month will continue to change. Initially, a large portion of your EMI is paid in interest while a minimal amount is paid toward paying down the principal balance. Over time, as you make your repayments or as your principal balance decreases, the interest payment will continue to decline.Towards the latter part of the loan, most of the EMI goes towards the repayment of the principal amount.

This is referred to as the reducing balance method, in which you pay interest only on the outstanding loan amount, not the original amount.

Prudent Borrowing Tips

To help choose the best loan arrangement for you, be sure to use the following tips:

First, when evaluating different loan amounts, interest rates and durations of loans, use an EMI calculator to discern what would be best for you before applying to any lender.

Second, do not try to take out a loan with a very long duration solely for the purpose of decreasing your EMI; find out how much additional interest you would have to pay.

Third, if permitted, consider making prepayment(s) / part prepayment(s) as this would reduce your principal and decrease your total interest.

Fourth, do not borrow more money than what you require; do not take a bigger loan just because the EMI is lower than the actual amount you would pay in a smaller loan. Ensure EMI falls comfortably within your monthly income so repayments do not disrupt essential expenses. Understand whether your loan has a fixed or floating interest rate; the latter may change over time.

Conclusion

The structure of your loan is based upon your EMI, interest rate and tenure. Once you know how these elements interact with each other, you will be able to make informed financial decisions and be less anxious about repayments on loans because you have a complete picture of your monthly instalments, when they will end and how much they will ultimately cost over time.When you understand these concepts clearly, you will be better equipped to plan, deal with unexpected future expenses, and pay off your loan effectively and with confidence.
