The credit card minimum payment trap, explained

Paying the minimum due keeps a card “current” in the sense that matters for a credit score, but that says nothing about whether the actual balance is going anywhere. Often, it barely is.

Why the minimum due can fail to shrink the balance at all

The minimum due is a percentage of next month’s statement balance — which already includes this month’s interest, added before that percentage is applied. Unless the minimum due percentage clears the monthly interest rate with real room to spare, the payment barely covers the new interest, and the balance doesn’t reliably shrink.

Even when it technically works, it’s brutally slow

This calculator’s own default (the same ₹50,000 balance at 3.5%/month, but a 5% minimum due instead of 3%) does clear the math needed to shrink the balance. That doesn’t mean it shrinks at any usable pace.

Run the same decay rate forward and the balance does eventually reach zero — in roughly 53 years. Over just the first 30 of those years, the minimum-due path costs ₹1,04,238.80 in interest on an original ₹50,000 purchase, without the balance ever actually clearing.

There is a way out of a revolving balance

Most issuers offer a way to escape this specific trap: converting the outstanding balance into a fixed-tenure EMI at a much lower rate than the card’s own revolving rate. Whether that conversion is actually worth it, and when the one-time processing fee outweighs the interest saved, is a separate question with its own math.
