Credit utilisation ratio is the percentage of your available credit that you are using. For a credit card with a Rs 1,00,000 limit and a Rs 25,000 outstanding balance, it is 25%. CIBIL identifies utilisation as one of the factors affecting your credit score, alongside repayment history, account age and credit enquiries. The calculation helps explain why paying on time and using a large share of a card limit are different parts of your credit profile.
| Question | Answer |
|---|---|
| What is the formula? | Outstanding card balance divided by credit limit, multiplied by 100 |
| What does 25% mean? | One quarter of the limit is being used |
| Does this calculate a CIBIL score? | No, it calculates a usage percentage |
How to calculate credit utilisation ratio
Start with two figures for the same card: its credit limit and the outstanding balance you want to measure. Divide the balance by the limit, then multiply by 100. Both rupee figures must refer to the same point in time if you want a meaningful comparison. Using an old limit with a new balance can give you a misleading percentage.
The formula is: utilisation (%) = outstanding balance / credit limit × 100. In the example above, Rs 25,000 / Rs 1,00,000 × 100 = 25%. This is a calculation of how much borrowing capacity is occupied. It does not measure your income, savings or how much of the balance you can comfortably repay.
Consider a second hypothetical card with a Rs 50,000 limit. If its balance is Rs 10,000, utilisation is 20%. If the balance rises to Rs 35,000 with the limit unchanged, utilisation becomes 70%. The increase is 50 percentage points, even though the borrower remains below the card's maximum permitted limit.
The reverse calculation also helps make percentages concrete. Thirty per cent of a Rs 50,000 limit is Rs 15,000, calculated as Rs 50,000 × 30 / 100. Thirty per cent of a Rs 1,00,000 limit is Rs 30,000. The same ratio therefore represents very different rupee balances on cards with different limits.
What is a good credit utilisation ratio?
In its consumer education article on credit card use, CIBIL describes spending restricted to 30% of the limit as a healthy ratio. This is educational guidance. That page does not establish a guaranteed score gain for staying at 30%, or a fixed points penalty for crossing it.
For example, Rs 29,000 against a Rs 1,00,000 limit equals 29%, while Rs 31,000 equals 31%. The difference is two percentage points of utilisation. It would be incorrect to convert that difference into a specific number of CIBIL points using the utilisation formula. That formula contains no information about the rest of the borrower's credit record.
CIBIL's guide to understanding a credit report says higher utilisation can suggest that a borrower is financially stretched. It also identifies payment history, credit age and enquiries as major score factors. Consequently, a low ratio alone cannot establish what score someone should have.
How does utilisation work with two credit cards?
For a simple combined calculation, add the balances and add the limits before dividing. Suppose card A has a Rs 1,00,000 limit and Rs 40,000 outstanding. Card B has a Rs 50,000 limit and Rs 5,000 outstanding. Combined utilisation is Rs 45,000 / Rs 1,50,000 × 100 = 30%.
The individual ratios are 40% and 10%. Averaging those two percentages would produce 25%, which is wrong for the combined calculation because the limits differ. This example shows how to calculate an aggregate percentage; it does not describe the weight CIBIL assigns to individual accounts inside its scoring model.
Changes in the denominator matter too. With Rs 25,000 outstanding, a Rs 1,00,000 limit produces 25% utilisation. A hypothetical reduction of the limit to Rs 50,000 produces 50%, despite no additional borrowing. If a limit rises instead, the percentage can fall without the debt falling. A lower percentage and a smaller rupee obligation are separate outcomes.
What should you compare in your credit report?
CIBIL's report guide describes account information including the lender, account type, current balance, overdue amount and repayment record. Compare those details with your own records before interpreting a percentage. An amount overdue describes a payment problem; an outstanding balance describes money still owed. A utilisation calculation alone does not tell you whether a payment is late.
The official CIBIL questions and answers also explain that the bureau compiles information supplied by lenders and cannot independently change those records. If the balance is inaccurate, investigate that discrepancy rather than assuming a different percentage will fix it. Our guide to credit report corrections explains that separate process.
