Personal Loan vs Credit Card: Which Is Actually Cheaper?

Rs. 2 lakh unplanned expense. Personal loan at 13% for 24 months = EMI Rs. 9,500. Credit-card revolver at 42% = interest Rs. 70k/year on unpaid balance. For ANY borrowing beyond a month, personal loan crushes credit card by 3-4x in cost. Yet Indians default to cards because approval is instant and the cost is invisible until the first interest-bearing statement arrives. Understanding which tool fits which situation saves Rs. 50-80k on a typical borrowing event.

By the end, you will know when each instrument is the correct tool, the math threshold, the 30-45 day free-credit window that credit cards uniquely offer, and the card-EMI conversion that matches personal loan rates.

The two windows. When each tool is right

CREDIT CARD: best used as 30-45 day FREE CREDIT (billing cycle + grace period) if paid in full by due date. The grace period is your interest-free float. A purchase on day 1 of the billing cycle gets 50+ days of free credit until due date. Beyond that (revolving balance), credit card becomes the WORST-POSSIBLE interest rate in retail credit. 36-48% annualised.

PERSONAL LOAN: best used for planned 1-5 year needs (wedding, medical, higher education top-up) where monthly EMI fits budget. Interest rates 12-18% depending on credit profile and employer. Fixed EMI, fixed tenure, predictable. Processing fee 1-2% upfront. For any borrowing beyond 2 months, personal loan math dominates.

Effective cost comparison

Credit card revolver

42% effective

Compounded daily

For a Rs. 2 lakh borrowing for 24 months: personal loan total interest ~Rs. 28k + Rs. 3k processing fee = Rs. 31k cost. Credit card revolver at 42% for 24 months: total interest + principal compounding = Rs. 1.3-1.6 lakh cost depending on paydown pattern. Card revolver costs 4-5x more.

Card EMI conversion. The middle ground

Most credit cards offer EMI CONVERSION on specific large purchases at 14-18%. Roughly matching personal loan rates. Terms: (a) minimum purchase amount typically Rs. 2,500-Rs. 10,000, (b) tenure 3-24 months, (c) processing fee 1-2% of amount, (d) 18% GST on interest (additional, often overlooked). Net effective rate after GST: 18-22%. Still much better than revolving at 42%, but slightly costlier than direct personal loan.

When card EMI beats personal loan: small amounts (Rs. 20-50k) where personal loan processing overhead + documentation is not worth it. Personal loan minimum typically Rs. 50,000; for smaller needs, card EMI is the fastest route. When personal loan wins: amounts > Rs. 1 lakh, tenures > 12 months, where lower base rate compounds into meaningful savings.

Convert to EMI on card

Most cards offer EMI conversion at 14-18% + 18% GST on interest. Effective rate ~18-22%, roughly matches personal loan. Use this instead of revolving at 42%. Read fine print for GST, foreclosure charges, and minimum-tenure conditions.

Convert to EMI on card

Card EMI conversion at 14-18% + GST on interest ~= 18-22% effective. Matches personal loan. Use this vs revolving at 42%. Watch fine print.

Personal-loan alternatives for specific uses

Education loan (section 80E interest deduction, no cap) for education use cases. Gold loan (9-13% bank, 13-24% NBFC) for short-term secured borrowing. LAP (loan against property) at 9-12% for large multi-year needs. Each has niche advantages vs generic personal loan.

Pre-approved personal loan offers

Banks push pre-approved personal loans to good-profile customers. Rates 10-14%, instant disbursement, minimal paperwork. Worth accepting if genuine need + rate is good; routine at banks like HDFC / ICICI for 3+ year salary customers. Decline otherwise; unused offers lapse harmlessly.

Key Takeaways

Credit card: 30-45 day free credit only if paid in full each cycle.
Personal loan: planned 1-5 year needs at 12-18% with fixed EMI.
Revolving cards = 42% = ~4x personal loan cost over 2 years.
Card EMI conversion can match personal loan rate for mid-sized amounts.
Never roll unpaid card balance beyond one cycle.
