Credit utilisation and your CIBIL score explained

Updated 30 Oct 2026 · by SwipeWise editorial team · how we write

Credit utilisation is the share of your card limit that is in use. It can be worked out from the limit and balance of each card. This guide shows the arithmetic, explains what RBI’s rules say about reporting to credit information companies (CICs, the bureaus), and says plainly what we could not confirm.

A note on sources. TransUnion CIBIL’s website blocked automated access, so we could not read its own pages on utilisation. We therefore do not state how CIBIL weighs utilisation or what ratio it considers good. The regulatory points below come from RBI documents and two issuers’ MITCs.

The arithmetic

Utilisation = balance shown on your cards divided by total credit limit, as a percentage.

Example (invented figures, for the arithmetic only): two cards with limits of ₹1,00,000 and ₹50,000, total ₹1,50,000. Balances of ₹30,000 and ₹15,000 give ₹45,000 / ₹1,50,000 = 30%.

Per card: ₹30,000 / ₹1,00,000 = 30% and ₹15,000 / ₹50,000 = 30%. If the whole ₹45,000 sat on the ₹50,000 card, the overall figure would still be 30% but that card would be at 90%. Check whether your own report shows both figures for each card.

Closing a card changes the denominator. With ₹30,000 owed on the ₹1,00,000 card and nothing on the ₹50,000 card, utilisation is 30,000 / 1,50,000 = 20%. If the ₹50,000 card is closed, it is 30,000 / 1,00,000 = 30%. RBI’s 2025 card directions require the issuer to report the closure of a card account to the CICs, and to update the CIC within 30 days where it closes a card unused for more than a year.

What reaches the bureaus, and when

RBI’s amendment directions of 4 December 2025 for commercial banks (RBI/DOR/2025-26/110), in force from 1 July 2026, say each commercial bank must submit credit information as on the 9th, 16th, 23rd and last day of each month. The last-day file is a full file due by the 5th of the next month. For the other three dates only “incremental accounts” are sent, within four calendar days, including accounts where the outstanding balance has changed because of an action by the borrower such as a repayment, and accounts with overdue amounts. The text applies to commercial banks; we did not check what applies to non-bank card issuers. We read the text as reproduced by TaxGuru, not on rbi.org.in.

So balance changes can reach a bureau several times a month. What we could not confirm is which figure a given issuer sends as your card balance (statement balance, current balance or another) or when a bureau displays it. Many articles say that paying before the statement date lowers the reported balance. We found nothing in RBI’s text or the MITCs to confirm that. SBI Card’s MITC says it submits cardholder data to a CIC weekly. Open your own report, find the balance and the date it was last updated for each card, and compare with your statement.

Late payment, default and corrections

  • RBI’s card directions say an account can be reported as past due to CICs only if it remains past due for more than three days, counted from the due date on the statement.
  • Before reporting a default, issuers must follow a Board-approved procedure and inform the cardholder. If you settle after being reported, the issuer must update the status with the CIC within 30 days of settlement. HDFC Bank’s MITC says updates appear in CIBIL and other bureaus within 30 days of receiving payment; SBI Card’s MITC says 45 to 60 days.
  • RBI’s Credit Information Companies Directions, 2025, as reproduced by TaxGuru, include one free full credit report, including the score, in each calendar year, and a 30-calendar-day limit for resolving a complaint, with the lender getting 21 days and the CIC the rest. They provide for compensation of ₹100 per calendar day of delay beyond the 30 days. We did not read these from rbi.org.in.

Limits and increases

RBI’s card directions say issuers must assess the credit limit for a customer taking into account all limits from other lenders, using self-declaration or CIC data, and must not raise a limit without the cardholder’s explicit consent. A higher limit adds to the denominator, which lowers the ratio for the same spending. See how banks set limits.

What we cannot verify

  • The “30%” level is widely quoted. We found no TransUnion CIBIL page to confirm it as a threshold, so treat it as a rule of thumb, not an official figure.
  • How much utilisation moves a score for any one person, and the relative weight of payment history, account age and enquiries, is not something we could confirm from CIBIL’s own material.
  • Whether paying before the statement date improves a reported ratio, for the reason above.

Interest, though, is documented

Carrying a balance costs interest regardless of any effect on a score. SBI Card’s MITC quotes up to 3.75% per month (45% a year) and HDFC Bank’s quotes 3.75% for most variants; see interest and minimum due and the billing cycle guide.

What to check before you apply

  • Your report for errors, and the balance and limit shown for each card.
  • Your total limit and balances, and the resulting ratio.
  • Whether you can pay the full bill each month.
  • The issuer’s eligibility terms. Approval is the bank’s decision and no outcome is guaranteed; entry options are in our first credit card picks.
