When you compare the various options available to borrow funds, loans often stand out for several reasons. You get access to larger amounts, and interest rates are much lower than credit cards. However, chief among them is the predictable and systematic process of repayments.
That said, if for any reason there is a delay in a scheduled repayment, the amount you owe to the bank can quickly get out of hand. This is primarily due to penal interests. If you don't know what they are, you are in the right place. This post will tell you everything you need to know about them, from why they exist to how they are calculated and more.

Penal Interest, as the name suggests, is a penalty in the form of added interest that is levied when an EMI payment has been missed or delayed. It is not a part of the interest component that you already pay as part of your EMI, but rather:
The penal interest is always mentioned in the loan agreement, so do go through the document carefully before you commit to a loan.
Lenders charge penal interest for several reasons.
Lending comes with an element of risk. Delayed payments mean their cashflows are hampered. It also adds to their operational costs as it leads to follow-ups, system adjustments, and additional monitoring.
Penal interest helps offset these operational costs without increasing regular interest rates for compliant borrowers.
Most importantly, it encourages customers to prioritise EMI payments when they know that any delays will incur additional costs.
Penal interest calculation depends on the terms mentioned in your loan agreement. In most cases:
However, the exact method may vary by lender and product.
For example, consider that your EMI amount is ₹10,000 per month and is due to be paid on the 5th of each month. Per your loan agreement, the lender will charge you a penalty interest of 2% per month.
If you say pay your EMI on the 15th instead of the 5th, then the penal interest works out to be: EMI × (2% / 30) × 10 days = ₹10,000 × 0.0006667 × 10 ~ ₹66.67
However, this is not the only additional charge you may encounter in the event of a delayed payment. Some lenders also levy a flat late payment fee and/or EMI bounce charges. Additionally, a 18% GST is applied to these extra payments.
Thankfully, the RBI enforces that penal charges are to be non-compounding and can only be levied on overdue amounts.

The only way to avoid paying penal interest is to clear your EMI due on time. To do this:
Most importantly, never over-borrow. Always ensure that your debt-to-income ratio, i.e., all your EMIs put together, is less than 30 to 35% of your take-home income.
If, for some reason, you know beforehand you may not be able to pay your EMI on time, get in touch with your lender. They may offer temporary solutions like loan restructuring or guidance, and in some cases, even defer penal charges for a grace period.
While penal interest itself does not directly lower your CIBIL score, the reason it's levied (the delayed or missed payment) does. Lenders are required by law to report delayed payments to credit bureaus, and each delayed payment drops your credit score by at least 50 points (more if the delay is more than 30 days).
The lower your credit score drops, the lower your access to credit and the possibility of future loans being approved.
