The Minimum Payment Trap

Banks didn't invent the minimum payment to be helpful. They invented it to be profitable. Drag the sliders. Watch the math destroy you in real time.

Real numbers · ₹50,000 balance @ 36% APR · paying minimum only

Pay only the minimum on a typical Indian credit card and this is what happens.

For comparison · paying ₹5,000/month would clear it in 12 months and cost ~₹9,000 in interest. Same debt. Same APR. Five times less pain.

Where your money goes

The trap: A ₹2,500 minimum on a ₹50,000 balance means about ₹1,500 goes to interest and only ₹1,000 actually reduces your debt. You're essentially renting the bank's money — and the rent is ridiculous.
Two perspectives

Why does the minimum payment exist?

The bank's plan

Keep you barely able to pay

  • Minimum is set at 2-5% of balance — just enough to keep your account "in good standing"
  • ~60% of your minimum payment goes to interest, not principal
  • Interest income is the largest revenue stream for credit card divisions
  • The longer you carry a balance, the more they earn — without doing anything
  • "Convenience" features like EMI conversions are just other ways to keep you paying interest
Your move

Pay it in full. Always.

  • Pay full statement balance before due date — zero interest, ever
  • Set up auto-pay for full balance — remove human decision from the loop
  • Treat your card as a 30-day float, not a loan source
  • If you can't pay the full balance, pay as much as possible — every extra ₹100 saves ~₹3 in interest each month
  • Never use credit cards for things you can't pay off this month
