What is a credit score, and what is CIBIL?
It does not measure whether you are good with money. It measures whether you have borrowed and paid it back.
What it measures, and what it does not
It does not measure wealth. Plenty of high earners carry mediocre scores, and plenty of modest earners carry excellent ones. It does not measure character, responsibility, or whether you are good with money in any broader sense.
It measures one thing: did you borrow, and did you pay it back, on time, repeatedly. That is the entire soul of it.
Which means the score has no idea you exist until you borrow something. This produces the system's famous cruelty: no history means no score, no score means no credit, and no credit means no way to build history. The credit invisible are not judged badly. They are not judged at all, which in a credit-driven economy is functionally worse.
How it is actually calculated
The exact formulas are proprietary, but the weightings are broadly consistent across bureaus and markets. Repayment history carries the most weight by a distance: a pattern of on-time payments, unbroken, over years. Next comes utilisation, meaning how much of your available credit you are currently using. A person using 80 percent of their limit looks stretched; a person using 20 percent looks comfortable, even if both pay on time.
After those two, the length of your history, the mix of credit types, and how recently you have applied for new credit each contribute something smaller.
The myths worth killing
Checking your own score does not lower it. Bureaus distinguish between your own enquiry and a lender's.
Closing an old credit card can genuinely hurt you, because it shortens your average account age and removes available limit, raising your utilisation ratio on everything else.
Having no debt at all is not the same as good credit. A person who has never borrowed is invisible, not virtuous.
And you can check the raw material yourself. Pull your own report free once or twice a year and read the report rather than just the number: errors are genuinely common, they are disputable, and disputes work.
It is a reference letter written by every institution you have ever borrowed from, in a language of two variables: did you pay, and how close to the edge do you live.
Where you meet it
Every loan application, credit card approval, and increasingly every rental agreement.
