The headline: credit card is cheaper only if you pay in full
A credit card at 0% (the grace period) is free. A personal loan at 11%–18% is not. The credit card wins by a wide margin — IF you pay the statemented balance in full.
If you don't pay in full, the credit card becomes the most expensive debt in India (3.5%–4.25% per month = 42%–51% per annum). The personal loan is dramatically cheaper.
The worked example
You borrow ₹5 lakh for 12 months.
Credit card (paid in full during grace period)
- Borrow ₹5,00,000.
- Pay ₹5,00,000 by the due date (within the grace period).
- Cost: ₹0 in interest. Possibly a 1.5%–2% processing fee if you take a cash advance, but if you charge purchases, no fee.
Credit card (revolving balance)
- Borrow ₹5,00,000 (cash advance or carry over).
- Pay 3.5%–4.25% per month (42%–51% per annum).
- Total interest over 12 months: ₹1,80,000–₹2,10,000.
- GST on interest: ₹32,400–₹37,800.
- Total cost: ₹2,12,400–₹2,47,800.
Personal loan at 13% per annum
- Borrow ₹5,00,000.
- Processing fee: 1%–2% + GST = ₹5,900–₹11,800.
- Interest: ₹36,500 (approximately).
- Total cost: ₹42,400–₹48,300.
Loan against credit card at 16% per annum
- Borrow ₹5,00,000.
- Processing fee: 2% + GST = ₹11,800.
- Interest: ₹43,500.
- Total cost: ₹55,300.
The 5X cost difference
The credit-card revolving rate (42%–51%) is 3X–4X more expensive than a personal loan (11%–18%). If you're considering a credit-card cash advance to fund a purchase, the personal loan is dramatically cheaper.
When the credit card is the right tool
Short-term float
If you have a ₹1 lakh purchase due in 30 days and you have the cash to pay, but you'd rather earn 30 days of interest on the cash, charging the credit card and paying the statemented balance in 30 days is free. You're effectively borrowing for free.
Reward optimisation
If you spend ₹5L/year on credit cards and earn 3% in rewards, the rewards (₹15,000) are a real offset to the cost of paying interest (if you pay in full). But the rewards don't justify revolving interest — the math is asymmetric (rewards are 3%, revolving is 42%).
Foreign currency purchases
For international purchases, the credit card with 0% forex markup (HDFC Infinia, DCB) is dramatically cheaper than other options. Even with the rewards, the savings on forex markup alone justify the credit-card use.
When the personal loan is the right tool
Large purchases you can't pay in full
If you need to buy a ₹5L laptop and can't pay the full amount in 30 days, the personal loan is dramatically cheaper than revolving on a credit card. Even a personal loan at the higher end (18%) is 3X cheaper than credit-card revolving.
Debt consolidation
If you've already accumulated a credit-card balance and can't pay it off in full, take a personal loan to pay off the credit-card balance. The personal loan at 11%–18% is 3X cheaper than the credit card at 42%–51%. You'll save thousands in interest.
Long-term financing
For purchases you'll finance over 24–60 months (home renovation, wedding, large medical), the personal loan is the right tool. The credit card's EMI conversion is shorter-term (3–24 months) and more expensive than a personal loan.
The decision matrix
| Need | Best tool |
|---|---|
| ₹1L for 30 days, can pay in full | Credit card (free) |
| ₹5L for 12 months, can pay in full | Personal loan (cheaper if not) |
| ₹5L for 5+ years | Personal loan or home loan |
| International purchase, can pay in full | 0% forex credit card |
| Cash advance | Personal loan (don't use credit card) |
| Existing credit-card balance | Personal loan to consolidate |
The hidden cost of personal loans
Personal loans have costs the headline rate doesn't show:
- Processing fee: 1%–2% of loan amount.
- GST: 18% on processing fee.
- Documentation fee: ₹500–₹2,000.
- Foreclosure fee: 2%–4% of outstanding if you prepay.
- Insurance bundling: some banks require you to take a credit-life insurance policy with the loan (₹5,000–₹15,000 added cost).
- Income requirement: the bank may require minimum income proof that excludes some applicants.
Total cost of a personal loan: typically 2%–5% above the headline rate.
The hidden cost of credit cards
Credit cards have costs the headline rate doesn't show:
- GST: 18% on all fees and interest.
- Annual fee: ₹0–₹12,500.
- Forex markup: 1%–3.5% on international transactions.
- Cash advance fee: 2.5%–3.5% of the cash amount.
- Late fee: ₹100–₹1,200 per missed payment.
Total cost of a credit card: 0%–3.5% above the headline rate (depending on usage).
The right credit card use case
The credit card is designed for:
- Disciplined transactors who pay in full every cycle. They earn rewards + 0% forex markup + dispute protection.
- Short-term float of 18–25 days within the grace period.
- High-reward categories (dining, travel) where rewards exceed interchange.
The credit card is NOT designed for:
- Long-term borrowing. Use a personal loan.
- Cash advances. Use a personal loan or your savings.
- Revolving balances. Convert to EMI or pay off.
The bottom line
The credit card is free if you pay in full. The credit card is the most expensive debt in India if you don't. The personal loan is 3X–4X cheaper than revolving on a credit card. The right tool depends on your discipline and your timeline. Use the credit card for transactors; use the personal loan for borrowers. The math rarely lies.
