About this tool
See how many years and how much interest it takes to clear a credit card balance if you only ever pay the minimum due.
Credit Card Minimum Due Calculator simulates your card balance month by month when you pay only the minimum amount due. It applies the monthly finance charge, adds 18% GST on that interest, recalculates the shrinking minimum each cycle, and reports how many years the debt lasts and what it costs in total. It also compares that against paying a fixed amount every month, so you can see exactly what the minimum-due trap costs you.

No shortcut formula — the balance, interest, GST and recalculated minimum are stepped through every cycle.
18% GST on the finance charge is tracked separately rather than capitalised, in line with card interest rules.
See the months and rupees saved by paying a fixed amount instead of the minimum due.
Your account stays current and no late fee applies, but interest keeps accruing on the revolved balance. On a typical Indian card at 3.5% per month with a 5% minimum, a 1 lakh balance takes well over 30 years and costs several times the original amount in interest and GST.
Most Indian issuers set it at around 5% of the total outstanding, subject to a floor of about 100-200 rupees, plus any EMI instalments, over-limit amount and past dues. Check your statement — the exact formula varies by issuer.
It avoids the severe hit of a missed payment, but the high outstanding balance keeps your credit utilisation elevated, which typically drags the score down. It also means you lose the interest-free grace period on new purchases until the balance is cleared in full.
Yes — 18% GST applies to interest and other card charges in India. This calculator adds it on top of the finance charge so the total cost you see is realistic. This is general information, not tax advice.
