How this calculator works
Credit card interest in India is 36–48% per annum — the most expensive form of debt. Paying only the minimum (5% of balance) on a ₹1L balance means it takes 5+ years and costs you ₹70,000+ in interest to repay. This calculator shows the real numbers.
Monthly interest = Outstanding balance × (Annual rate / 12) | Payoff timeline: Month by month balance reduction

Never pay only minimum
The "minimum due" trap is one of the most expensive mistakes in personal finance. Always pay the full statement balance.
Grace period is your friend
If you pay the full balance before the due date, you pay zero interest. The 45–50 day grace period is free credit.
Balance transfer to 0%
Some cards offer 0% balance transfer for 3–6 months. Use this to pay off high-interest card debt faster.
