Assumptions

  • Indian credit cards typically quote a monthly finance charge (commonly 3-3.5%) rather than an annual rate — this calculator shows both.
  • Assumes interest accrues on the full outstanding balance from the statement date, the common practice when only the minimum due is paid.
  • Informational only.

Frequently asked questions

Why do credit cards charge such high interest?

Credit card debt is unsecured and revolving, carrying higher risk for the lender than a secured loan — this is reflected in significantly higher interest rates, often annualizing to 40-50%+.

How can I avoid credit card interest entirely?

Pay your full statement balance by the due date every month — interest only applies to outstanding balances carried beyond the interest-free grace period.

Does paying the minimum due avoid interest?

No — paying only the minimum due still accrues interest on the remaining outstanding balance, which is why credit card debt can grow quickly if only minimum payments are made.

Why Paying Only the Minimum Can Cost More Than Your Original Balance
