Minimum-Due Interest Shock

Short answer

Enter your bill and this tool shows what paying only the minimum due (5%) costs: the months to clear the balance and the total interest, modelled at a typical ~3.6% per month rate (indicative, as of 2026). Paying in full always shows the same result β€” β‚Ή0.

Minimum-Due Interest Shock

See what paying only the minimum due actually costs β€” months to clear and total interest, on any bill size, at a typical Indian card rate.

You pay monthly
~β‚Ή62,935extra interest on a β‚Ή30,000 bill, paying only minimum (5%) each month for 10 years β€” and it is still not cleared. That is with zero new spending.

Illustrative model at a typical rate; actual bank rates vary (roughly 2.5–4% per month, as of 2026). The lesson doesn’t vary: pay in full.

What this tool does

It runs a simple amortisation: each month, interest is added to the balance and a payment is subtracted, until the balance clears (or 120 months pass). You choose whether the payment is the minimum (5%), half the bill, or the full amount.

The full-payment option always returns the same answer: β‚Ή0 interest. That is the entire lesson, made visible.

Why the numbers look so bad

Three mechanics compound:

  1. Interest applies to the entire balance, not just the unpaid portion.
  2. The minimum payment shrinks as the balance shrinks, so progress slows over time.
  3. New purchases would lose their grace period β€” and this model does not even include them.
The model assumes zero new spending, which is the most optimistic possible assumption. A real card in real life usually clears more slowly than this.

What the tool cannot know

  • Your card's exact interest rate (check the schedule of charges).
  • Your issuer's exact minimum-due formula, which typically includes EMIs, fees and taxes in full.
  • Whether interest is calculated daily or monthly, which changes the total slightly.

That is why every output is labelled illustrative. The direction of the answer is what matters, and it does not change with the rate.

What to do with the result

If the number shocked you: Set autopay to Total Amount Due today. That one change makes this calculator permanently irrelevant to your life, which is the outcome we are hoping for.

If you are already carrying a balance, read the minimum due trap for the practical way out β€” including when a structured EMI conversion is cheaper than revolving.

All figures on this page are indicative and dated. Rates and fees differ by bank and change over time. Always verify with your bank's official schedule of charges.

Frequently asked questions

What interest rate does this calculator use?

A typical 3.6% per month, which is roughly 43% a year β€” a mid-range figure for Indian credit cards as of 2026. Real rates run from about 2.5% to 4% a month depending on the bank and card, so treat the output as illustrative rather than a quote.

Does the model include new spending?

No β€” it assumes you stop using the card entirely, which is the most optimistic case. Real balances usually clear more slowly because new purchases lose their interest-free period the moment a balance is carried.
