What is a credit card revolving balance?

A revolving balance is the amount carried forward after a credit card balance is not cleared in full. It can continue to attract finance charges under the card issuer's terms. This calculator models the carried balance month by month.

What is the minimum payment used by this calculator?

The calculator uses a simplified assumption of 5% of the opening balance or Rs.200, whichever is higher. This is a model for comparison, not a universal rule for every card.

How long can it take to clear a credit card by paying only the minimum?

Under this calculator's default example of Rs.1,00,000 at 3.75% monthly interest with the simplified 5% minimum payment, adding GST on modeled interest can make the repayment period exceed the calculator's 600-month limit. This is a planning model, so use your own numbers and compare payment amounts.

Does adding a new purchase affect the payoff timeline?

Yes. A new purchase increases the balance that needs to be cleared. The calculator lets you add a purchase to a selected month and see how it changes the month-by-month repayment schedule.

Interest and GST

See modeled monthly interest and 18% GST on that interest as your balance is carried forward.

Repayment schedule

Follow the opening balance, interest, GST, payment, principal reduction, fees and closing balance month by month.

Minimum due and scenarios

Credit Card Balance, Revolving Balance and Interest

Your credit card balance is the amount you owe. When you do not clear the full amount due and carry part of it into the next billing cycle, that carried amount becomes a revolving balance. It can continue to attract finance charges under your card issuer's terms. See our guide to how credit cards work for the billing cycle, credit limit, minimum due and repayment basics.

Monthly interest

Opening Principal x Monthly Rate

GST on interest

Monthly Interest x 18%

Principal balance

Opening Principal - Principal Paid + Purchases

This is a monthly planning model. Interest, GST and fees are kept separate from principal, so unpaid charges do not themselves generate interest in the model. Actual card finance charges can depend on transaction dates, daily balances, payment allocation and issuer-specific rules.

Why Paying Only the Minimum Due Can Take So Long

The minimum due may look manageable, but a large part of the payment can go toward interest, GST and other charges, leaving less to reduce the principal. That can keep a revolving balance around for a long time.

In this calculator, Minimum Due Only uses the simplified assumption of 5% of the opening balance or ₹200, whichever is higher. Try a higher payment above and compare the payoff time. For more detail, see why paying only the minimum due can cost more.

Frequently Asked Questions

A revolving balance is the amount you carry forward after not clearing the full amount due. It can continue to attract finance charges under your card issuer's terms. This calculator models that carried balance month by month.

The calculator applies the entered monthly rate to the opening principal balance for each month, then adds 18% GST on the modeled interest. Interest, GST and fees are tracked separately from principal, so unpaid charges do not themselves generate interest in this model. Actual card issuers can use transaction dates, daily balances and card-specific finance charge rules, so your bank's statement may differ.

The calculator uses a simplified assumption of 5% of the opening balance or ₹200, whichever is higher. This is a model for comparison, not a universal rule for every card. Check your statement for the actual minimum amount due.

It can take years. Under this calculator's default example of ₹1,00,000 at 3.75% monthly interest with the simplified 5% minimum payment, adding GST on modeled interest can push the payoff beyond 50 years. Use your own numbers because the result changes sharply with the rate and payment rules.

The selected month is shown as skipped, no payment is made, and the calculator adds its illustrative late fee assumption plus 18% GST. The missed payment increases the balance and can extend the payoff timeline. Actual late fee amounts and when they become payable depend on your issuer and card terms.

Yes. A new purchase increases the balance you need to clear. Use the + Purchase button to see how a new spend changes the month-by-month repayment schedule. The calculator uses a monthly model, so the purchase is added to that month's closing balance.

If you can afford to pay more without missing essential expenses, a higher payment generally reduces the time you carry the balance and the interest charged under the calculator's model. Try two payment amounts and compare the payoff timeline rather than guessing.

Yes. The calculator models 18% GST on each month's calculated credit card interest. GST is kept separate from principal, so the GST amount does not itself generate interest in this model. Actual tax treatment and statement amounts can depend on the charges billed by your card issuer.

It is a planning model, not a replacement for your card statement. The calculator uses monthly interest on the opening principal balance, 18% GST on modeled interest, a simplified minimum due assumption and illustrative late fee slabs. Actual issuers can use transaction dates, daily balances and card-specific payment rules.

This calculator is a planning model.
