EMI vs Prepayment: How Home-Loan Interest Works

Understand home-loan principal, interest, amortisation, fixed and floating rates, illustrative repayment schedules, and prepayment trade-offs and lender terms.

EMI’s are usually composed of interest plus principal repayments. The initial EMIs paid when you take out a fully amortising loan will be higher in interest due to the higher outstanding principal. As you start to pay down your loan the interest charged on the outstanding will decrease and more of your payment will make up your principal.

Depending on your loan agreement you may be charged a fixed, variable or other specified rate. There may be fees attached as well as a rule about when you can reset your rate. Your repayment dates and any rules around prepayment will also affect your cost. To ensure you know what you’re paying you should refer to your sanction letter and loan agreement.

Principal refers to the amount still owed on your loan, interest refers to the cost of borrowing the money. An EMI is an amount that is to be paid based on your loan terms. In a standard repayment schedule, your EMIs will cover your interest payment for the period and you’ll be paying down the amount owed (outstanding). This will depend on how your lender calculates it and any additional fees.

As an example, let’s look at an example loan of 30 Lakhs with a hypothetical 8% rate and 20 year term. This EMI will not reflect current market rates and will not include all possible fees. Your monthly rate may vary, this is due to the day count convention and when payments are made. Ensure you refer back to your terms.

Why your initial payments look different.

Your interest will be calculated based on the outstanding principal. Initially your interest will be high as your outstanding will be large. However, as you make multiple repayments your principal will reduce and therefore your interest will reduce if your rate remains fixed. This is known as an amortisation schedule.

You will get a repayment schedule showing how much of each repayment is going towards interest, principal and a new outstanding balance. You should review this when you take out your loan, when you reset your rate and if you make a prepayment. Your rate may change and therefore your EMIs, term or both may change depending on your agreement and any regulations. Ensure you check with your lender what changes they have made.

Fixed and Variable Rates

With a fixed rate the rate will be fixed based on your contract. You should ensure you understand what “fixed” means and any rules around resetting or converting. With a variable rate your rate will be based on the benchmark, spread or other allowed terms. If rates increase your lender may increase your EMIs, term or both. If rates decrease it will depend on your terms and how it works.

A variable rate can mean there is some uncertainty around your repayments and total interest. A fixed rate may give you more certainty around your repayments, however there could be different rates or conversion terms. A fixed or variable rate does not necessarily mean one loan is cheaper overall. Check with your lender what the offer is, what the rules are around resetting and any fees. Also check how flexible your repayments are and how risky it is based on the rates.

Prepayments

A prepayment is an extra payment towards your outstanding principal. Based on your lenders processes the prepayment may reduce your outstanding balance which could result in a shorter term, lower EMIs or other changes. Ask your lender how they will apply this amount and if there is anything you need to tell them to do what you want.

Paying down your principal sooner means that your interest will be less going forward. This will depend on when you pay, how much is outstanding, your interest rate, how much time is left and any fees/conditions. If your loan has been running for years, ensure you use the current balance and rate in your calculator.

Example:

If your outstanding balance was hypothetically 20 Lakhs and you paid an extra 1 Lakh towards your principal. Assuming your lender applies the full amount to your principal with no fees you’ll now have an outstanding of 19 Lakhs. Your future interest will be less based on your terms.

This is not necessarily true, as the 1 Lakh you’re paying is already yours. The benefit of paying is that it avoids interest being paid on the outstanding. However, if you need this money for medical bills, emergency savings or something else urgent you may want to consider this.

Liquidity

Paying off your home loan can be satisfying as you’ll reduce your outstanding balance but you’ll have less liquid funds. Consider your emergency savings, upcoming bills, other debts, insurance requirements and how liquid your income is. You may not be able to get this money back easily unless you apply for further borrowing. How much liquidity you have will depend on your situation.

Opportunity Cost

By paying off your loan you’re losing the opportunity to use this money for something else. While you may get a guaranteed reduction in interest based on your contract, there may be uncertainty around how much you could get back from investing. This may be taxed and there may be risk involved. This article will not advise what is best for you.

Lenders Terms and Fees

Ensure you understand your lenders terms and conditions. Check if there is a minimum amount you can pay, if there is a certain method you can make the payment through, how it will affect your EMIs, term, if partial prepayments are allowed and any fees for this specific loan type and category. Regulations can vary depending on your loan and may change.

Save your proof of payment and ask for an updated repayment schedule. Ensure that your payment was applied to your principal and see what your new outstanding is. If your lender gives you the option to reduce your EMIs or term understand the impact it will have on your cashflow and interest.

Common mistakes with EMIs.

Your calculator may assume your rate is fixed throughout your term. However, if you have a variable rate there may be a reset. There may not be any fees, insurance, tax or other fees included. Your calculator may assume a standard monthly repayment schedule when your lender may have different calculations. This will be a model.

Comparing loans based solely on the EMIs. Your EMIs may be lower because your term is longer and your total interest is higher. Check what your rate is, what your total payments will be based on the assumptions, fees, reset terms, flexibility of prepayment and how long your loan is for. Ask your lender for a full amortisation schedule.

Conclusion

Your EMIs will include payments towards your interest and principal. By making a prepayment your lender may reduce your principal sooner. You should consider if you want to pay less interest based on how liquid you are, any other commitments and what the terms of your contract are. Having a fixed or variable rate will have different levels of certainty and risk. Ensure you check with your lender what the terms are and what the current RBI guidance is. Do not rely on an example calculator and should refer to your lenders repayment statement.

What happens when your rate resets?

If you have a variable rate loan, ensure you understand what your lender has said. Check what your new rate, outstanding principal, EMIs and term are. Your payment may be the same but your term may have increased which could impact your total interest. If your EMIs have increased ensure your household can afford this. Ask your lender how they have calculated this and what options there are within your agreement.

Do not assume that your loan will shorten or your EMIs will reduce if your rate goes down. This will depend on the terms of your contract and how your lender processes it. Save all your updated schedules so you can track how your balance and term are changing. If your statement does not seem to make sense ask your lender via their official channel.

Track all payments to principal.

Save your proof of payment and ask for an updated loan statement. Ensure your payment has been applied to your principal and see what your new balance is. If your lender allows you to reduce your EMIs or term ask for both schedules. This will show the difference in cashflow.

Ensure you make your prepayment using your lenders authorised method. Do not send money into your own account or rely on someone promising to apply it to your loan. Ensure you have proof from an official statement.
