The Traditional Player: Personal Loans
A personal loan is a classic financing tool. A bank or an NBFC gives you a lump-sum amount of money that you repay in fixed monthly installments (EMIs) over a predetermined period, typically ranging from one to five years. These are unsecured loans, meaning
you don’t need to provide collateral. Personal loans are designed for significant, planned expenses like funding a wedding, covering medical emergencies, renovating your home, or consolidating other debts. The application process involves a thorough credit check, income verification, and other documentation. Because the structure is transparent, you know the exact cost of borrowing from day one—the interest rate and EMI are fixed, making it easier to budget for repayments.
The New Challenger: Buy Now, Pay Later (BNPL)
Buy Now, Pay Later is a form of short-term, point-of-sale financing that has exploded in popularity, especially on e-commerce sites and food delivery apps. It allows you to purchase a product or service immediately and pay for it in smaller installments over a few weeks or months. Many BNPL services offer an initial interest-free period, which is a major part of their appeal. The convenience is unmatched: approval is often instant with minimal to no documentation, making it accessible even for those with a limited credit history. However, BNPL is best suited for small-ticket, impulsive purchases. The danger lies in missing a payment, which can trigger high late fees and interest charges, sometimes as high as 30-40% annually.
The Key Metric: Your Debt-to-Income (DTI) Ratio
Before comparing how these products affect you, it's crucial to understand the Debt-to-Income (DTI) ratio. This is a simple percentage that lenders use to assess your ability to manage more debt. The formula is your total monthly debt payments (including existing EMIs and credit card dues) divided by your gross monthly income, then multiplied by 100. For example, if your total monthly EMIs are ₹30,000 and your gross monthly salary is ₹1,00,000, your DTI is 30%. Lenders in India generally prefer a DTI ratio below 40-50%, as a lower number indicates you have enough income left over to handle a new loan payment without financial stress.
How Each Loan Type Affects Your DTI and Credit Score
A personal loan has a direct and predictable impact. The moment you take one, its fixed EMI is added to your monthly debt obligations, increasing your DTI ratio. Because personal loans are formal credit products, every on-time payment helps build a positive credit history, while any default is immediately reported to credit bureaus like CIBIL, damaging your score.BNPL's effect is more nuanced but equally important. Thanks to the RBI's Digital Lending Guidelines, most BNPL providers now operate in partnership with regulated lenders and are required to report your repayment behaviour. This means timely BNPL payments can help build your credit score, but defaults will hurt it. The bigger risk with BNPL is "debt stacking"—using multiple services for small purchases. While one ₹2,000 payment seems harmless, five such payments in a month add ₹10,000 to your obligations, straining your cash flow and indirectly worsening your ability to manage debt, even if it's not all immediately reflected in a formal DTI calculation by a bank.
Strategies for Responsible Digital Borrowing
Managing your DTI in the age of easy credit requires discipline. The first step is to always calculate your current DTI ratio before applying for any new credit. This gives you a clear picture of how much more debt you can realistically handle. Match the product to the purpose: use personal loans for large, planned expenses that require a longer repayment tenure, and use BNPL only for small, affordable purchases you are confident you can pay off within the interest-free window.Avoid the temptation of using multiple BNPL services simultaneously. It becomes incredibly difficult to track various due dates, increasing the risk of missed payments and late fees. Treat a BNPL payment with the same seriousness as a loan EMI. Set reminders for due dates to ensure you never miss a payment, protecting your credit score. Finally, if you find yourself juggling multiple debts, consider creating a clear repayment plan. Prioritise paying off high-interest debts first to reduce your overall interest burden and free up cash flow faster.
