Credit Cards
Credit Card Interest (Finance Charge)
~3.5%/month on revolved balances — the costliest common debt.
Unpaid balances attract finance charges around 3–3.5% per month (36–42% annualised), plus GST, with no interest-free window on fresh spends while you revolve. Cash advances add upfront fees and immediate interest. Never borrow on a card what you would not borrow at 40%.
Example
Revolving ₹50,000 for 6 months costs roughly ₹10,000+ in interest — more than most cards' yearly rewards.
