Why Borrowers May End Up Paying Higher Interest Than Expected?

In India, access to credit has expanded significantly. Credit cards, personal loans, EMI-based purchases, top-ups, and app-based credit facilities allow borrowers to access funds quickly and with minimal documentation. While this improves convenience, it can also make the long-term cost of borrowing less visible at the time of decision-making.

In many cases, higher interest outgo is not the result of a single large borrowing decision. It typically arises from a series of small, seemingly reasonable choices. Examples include opting for longer loan tenures to reduce monthly instalments, paying only the minimum amount due on revolving credit, postponing prepayments, accepting bundled add-ons without reviewing costs, or refinancing loans later in the repayment cycle. Individually, these actions may appear manageable. Over time, they can increase the total interest paid.

This article explains common structural and behavioral factors that can increase borrowing costs and outlines general considerations that may help borrowers better understand interest-related outcomes.

Why Can a Lower EMI Result in a Higher Total Repayment?

Loan comparisons are often made using the monthly EMI as the primary reference point. Extending the loan tenure usually reduces the EMI, which can make repayments feel more manageable from a cash-flow perspective. However, a longer tenure typically increases the total interest payable because interest is charged over a greater number of periods.

As a result, while the EMI may be lower, the aggregate amount repaid over the full tenure may be significantly higher. Evaluating both the EMI and the total repayment obligation provides a more complete picture of the cost of borrowing.

Why Does the Interest Component Appear Higher in the Initial EMIs?

Most standard loans follow an amortisation structure in which interest is calculated on the outstanding principal. Since the principal is highest at the beginning of the loan tenure, the interest portion of early EMIs is also higher. Over time, as the principal reduces, the proportion of each EMI allocated to principal repayment increases.

This structure is relevant when considering prepayments or refinancing. Prepayments made earlier in the tenure generally have a greater impact on reducing total interest, subject to the loan terms and how the lender applies such payments.

How Do Fees and Add-Ons Increase the Cost of Borrowing?

In addition to interest, loans may involve several ancillary charges that affect overall cost, including:

• Processing and documentation fees
• Applicable taxes on fees
• Credit-linked insurance products
• Charges for loan conversions or modifications
• Late-payment or cheque-bounce penalties

While these may not be described as interest, they increase the total repayment obligation and should be reviewed as part of the overall borrowing cost.

Which Common Habits Can Lead to Avoidable Charges?

Certain recurring patterns can increase borrowing costs:

•  Making minimum or partial payments that keep balances outstanding
• EMI bounces caused by timing mismatches or low account buffers
• Using credit for routine expenses without a defined repayment plan
• Maintaining low-yield cash balances while servicing high-interest debt

Improving payment discipline and maintaining a modest liquidity buffer can help reduce avoidable charges.

What Checks Help in Understanding the True Cost of a Loan?

General checks that support informed borrowing include:

1. Reviewing the total amount payable over the full tenure
2. Confirming whether the interest is flat or reducing-balance based
3. Examining the repayment schedule or amortisation structure
4. Understanding how prepayments are applied to the loan
5. Prioritising repayment of higher-cost borrowings
6. Setting up payment automation with sufficient balance buffers
