CIBIL is India's oldest and best-known credit bureau, and its score is the number most lenders pull first. It runs from 300 to 900, and above 750 is generally treated as comfortable for approval.
What the bands actually mean
Below 600 you will struggle to get an unsecured loan or a decent card at all, and offers that do arrive carry high rates. Between 600 and 700 approval becomes possible but the pricing is poor. Between 700 and 750 most lenders will say yes at ordinary rates. Above 750 you reach the band where you can negotiate, and above 800 you are in the territory where banks compete for you.
A special case trips people up: a score of -1 or NA/NH does not mean bad credit. It means there is no credit history to score — usually a young applicant who has never borrowed. Lenders treat it as an unknown rather than a negative, but it can still slow a first loan.
What moves the number
Five inputs, and they are not equally weighted.
Repayment history is the single largest factor. One payment more than 30 days late is recorded and visibly drags the score for a long time. This is the lever that matters most, and it is entirely within your control.
Credit utilisation is how much of your available limit you are using. Keeping it under 30% is the widely-used benchmark. Someone with a ₹2 lakh limit who habitually carries a ₹1.6 lakh balance looks stretched, even if every payment is on time.
Length of history rewards age. The oldest card on your file is doing quiet work, which is why closing it can lower your score rather than tidying things up.
Credit mix slightly favours a blend of secured borrowing, like a home or car loan, and unsecured borrowing like cards.
Recent enquiries count. Each formal application triggers a hard enquiry, and several within a short window reads as someone urgently seeking credit. Checking your own score does not do this — that is a soft enquiry and is free of consequence.
How to check it without cost
Every credit bureau operating in India is required to give you one free full credit report each year. You can also see a score free through many banking and fintech apps, though those often show a bureau other than CIBIL, so the number may differ slightly from the one your lender sees.
There is no reason to pay for routine monitoring, and no legitimate service can remove accurate negative information from your file.
Fixing errors, which are more common than people expect
Pull the full report, not just the score, and read the account list line by line. Loans you never took, accounts you closed years ago still showing open, an incorrect overdue amount, a duplicate entry — all of these appear regularly, and each one is costing you.
Disputes are raised free on the bureau's own website. The bureau must investigate with the lender, and the timeline is measured in weeks. Correcting a genuine error is the fastest available improvement, because it does not require you to change any behaviour.
Rebuilding a low score
There is no shortcut, and anyone selling one is selling a fraud. What works is unglamorous.
Clear every current overdue first, because an active default outweighs everything else. Then pay every bill on time without exception, since recent behaviour carries more weight than old behaviour. Bring utilisation down, either by paying balances or by requesting a higher limit and not using it. Stop applying for new credit while you repair. And keep old accounts open, because their age is an asset.
If you have no history at all, a secured card against a fixed deposit is the standard way to start one.
Expect visible movement in three to six months and a genuine recovery over a year or two. Our guide on how to improve your credit score sets out the sequence in more detail, and the related credit score entry covers how the other bureaus differ.
