Your credit card bill arrives with two big numbers on it: the total amount due and a much smaller minimum amount due. Pay the first and the card has cost you nothing. Pay only the second and you start paying card interest, which is usually far higher than the rate on a personal loan or home loan. Knowing how the bill is built is the difference between a free loan and an expensive one.
This guide walks through the statement date, due date, interest-free period, minimum amount due, finance charges and late fees, and then the RBI rules that protect you, including the rule that a card must be closed within seven working days of your request.
Statement date, billing cycle and due date
Three dates run your card account, and they are printed on every statement.
- Billing cycle: the period, roughly a month, over which your spends are collected into one bill. The RBI defines it as the regular length of time between the closing dates of two consecutive bills.
- Statement date: the day the cycle closes and the bill is generated. Everything you spent in the cycle appears on this bill.
- Payment due date: the last day to pay without interest or late fees. The RBI requires card issuers to give you at least a fortnight to pay before interest starts.
Issuers do not all use the same billing cycle. Under RBI rules, you must be given the option to change your billing cycle at least once, to any date you prefer, through channels such as the helpline, email, internet banking or the mobile app. If your salary comes on the 1st and your due date falls on the 28th, shifting the cycle so the due date lands after payday can save you a lot of stress.
How the interest-free period works
The RBI defines the interest-free credit period as the time from the date of a transaction to the payment due date, during which you pay no interest, on one condition: you must pay the entire outstanding by the due date.
As an illustration, say your cycle runs from the 16th of one month to the 15th of the next, and your due date is the 5th. A purchase made on 16 March lands on the bill dated 15 April and is due on 5 May, giving you about 50 days of free credit. A purchase made on 15 April lands on the same bill and gets only about 20 days. That is why the interest-free period is usually described as a range rather than a single number.
Two exceptions catch people out:
- Cash withdrawals on a credit card are priced differently from purchases. Your card’s most important terms and conditions must list the cash advance fee and the finance charges on cash advances, so read them before you use the card at an ATM. On many cards there is no free period on cash.
- Any unpaid balance kills the free period. RBI rules require the card’s terms to explain that the interest-free period is suspended if any balance from the previous bill is outstanding. Carry forward even ₹500, and new purchases start attracting interest from the day you make them.
Minimum amount due on a credit card bill
The minimum amount due (MAD) is the smallest payment that stops the bill from being treated as overdue. Paying it keeps you clear of late fees and keeps your account from being reported as past due. It does not stop interest.
The RBI requires issuers to set the minimum amount due so that there is no negative amortisation. In plain terms, your minimum payment must at least cover the interest, taxes and charges for the month, so the balance does not grow while you keep paying. The RBI’s own example: if a month’s interest is ₹200 and taxes and charges are ₹50, the MAD cannot be less than ₹250.
Every statement must also carry a warning that making only the minimum payment every month stretches repayment over months or years, with compounded interest on your balance. Take that warning seriously. Paying only the MAD on a large balance can keep you in debt for years while most of each payment goes to interest.
Finance charges: what you pay when you do not clear the bill
If you pay anything less than the total amount due, the interest-free period is lost for that bill. Interest is then charged from the date of each transaction, not from the due date. That is the part most people miss.
There is a protection here. RBI rules say that after a partial payment, interest is charged on the outstanding amount, adjusted for your payments, refunds and reversals as and when they are credited, and not on the total amount due. Unpaid charges, levies and taxes cannot be capitalised for charging interest on them.
As an illustration, say your bill is ₹40,000 and you pay ₹10,000 on the due date. Assume a card rate of 3.5% a month for illustration. You will pay interest on the full ₹40,000 from each purchase date until your ₹10,000 payment, and on ₹30,000 after that, until you clear it. Even for one month, the ₹30,000 alone costs about ₹1,050, plus taxes. Add the interest on new purchases that no longer get a free period, and a single partial payment can cost far more than people expect.
Card issuers must quote the annualised percentage rate (APR) for different situations, such as purchases, cash advances and late payment, and explain with examples how it is calculated. The APR and the annual fee must be shown with equal prominence. Look for this in the key fact statement and in the most important terms and conditions (MITC) that come with your card.
Late payment fees and the three-day rule
Late fees used to kick in the day after the due date. That is no longer allowed. Under the RBI’s directions, an issuer can levy late payment charges, or report your card account as past due to credit bureaus, only when the account remains past due for more than three days.
The days past due are still counted from the payment due date. So if your due date is the 5th and you pay on the 7th, you should not see a late fee or a bureau report, though interest will still apply because you missed the interest-free window. Pay on the 10th and the late fee, and a possible hit to your credit score, are back on the table.
Late fees too can be charged only on the outstanding amount after the due date, adjusted for payments and refunds, and not on the total amount due. The method of calculating the late fee and the number of days must be shown prominently. Any change in charges must be made with at least one month’s notice, and if a change goes against you, you can surrender the card without an extra charge after paying your dues.
RBI rules on your credit card bill at a glance
The rules above come from the RBI’s Master Direction on credit and debit cards, first issued in April 2022 and amended in March 2024. On 28 November 2025 the RBI re-issued these rules as separate directions for each type of card issuer, such as commercial banks and small finance banks, with the same core billing protections. The table sums them up.
| Rule | What it means for you |
|---|---|
| At least a fortnight to pay | The bill must reach you with at least 15 days before interest starts |
| Billing cycle change | You can change the billing cycle at least once |
| No negative amortisation | The minimum due must cover interest and charges, so the balance does not grow |
| Three-day grace on penalties | No late fee or bureau reporting unless past due for more than three days |
| Interest on outstanding only | After a part payment, interest is on what is left, not the whole bill |
| Disputed bills | The issuer must explain, with documents where needed, within 30 days of your complaint |
| Refunds before due date | Refunds and reversals must be adjusted against the payment due immediately |
| No credit limit breach without consent | The sanctioned limit cannot be crossed without your explicit consent |
Closing a credit card: the seven working day rule
Cancelling a card used to mean letters, calls and retention offers. The RBI has made it simpler. A request to close a credit card must be honoured within seven working days, provided you have paid all dues. Once the card is closed, you must be told immediately by email or SMS.
Issuers must let you ask for closure through several channels, such as the helpline, a dedicated email, IVR, a visible link on the website, internet banking or the app. They cannot insist on a request by post. If they fail to close the card within seven working days, they must pay you a penalty of ₹500 for each calendar day of delay until closure, provided there is nothing outstanding on the account.
A few related rules:
- If you have not used a card for more than a year, the issuer may start closing it after telling you. If you do not reply within 30 days, the account is closed once dues are paid.
- After closure, the closure must be updated with credit bureaus within 30 days.
- Any credit balance left on the card must be transferred to your bank account.
Before you close a card, think about your credit score. Closing your oldest card or a card with a large limit can raise your credit utilisation ratio. The site’s credit score guide covers this in detail.
Disputing a wrong charge on your bill
Read every bill, line by line, the day it arrives. If you spot a charge you do not recognise, call the issuer at once and block the card if fraud is possible. For a billing error or a disputed charge, raise a written complaint. The RBI requires the issuer to give you an explanation, and documentary evidence where applicable, within 30 days of your complaint.
If the issuer does not resolve it, escalate to its grievance officer. If you get no reply within 30 days of your complaint, or you are unhappy with the reply, you can complain to the RBI Ombudsman under the Integrated Ombudsman Scheme, 2026, which replaced the 2021 scheme from 1 July 2026. Filing is free, but you must first have complained to the card issuer, and the Ombudsman complaint should be made within 90 days of the reply or of the end of the waiting period. Keep screenshots, emails and reference numbers.
Key takeaways: a monthly credit card bill checklist
- Note your statement date and due date; change the billing cycle if it clashes with payday.
- Pay the total amount due, not the minimum, every month. Set up an auto-pay for the full amount if you can.
- Avoid cash withdrawals on a credit card.
- Remember that any carried balance removes the interest-free period on new spends.
- Check every line of the bill and dispute errors in writing.
- To close a card, clear your dues and ask through any official channel; the issuer has seven working days.
A credit card is one of the few loans that can cost you nothing. Treat the due date as a hard deadline and the full amount as the only amount, and it stays that way.
