What is CIBIL score and how is it calculated

You apply for a home loan at HDFC. You’ve been working for six years, you earn ₹85,000 a month, and you’ve never missed a salary. The loan officer types something into their system, glances at a number, and the whole conversation changes. That number is your CIBIL score — and most people have no idea how it actually works until it bites them.

Here’s what you need to know.

What Exactly Is a CIBIL Score

CIBIL stands for Credit Information Bureau India Limited. It’s one of four credit bureaus licensed by the RBI to track how Indians borrow and repay money. The score they generate — a three-digit number between 300 and 900 — tells any lender, in seconds, how likely you are to repay a loan.

Think of it as a financial trust score. The higher it is, the more banks compete to lend to you. The lower it is, the more they charge you — or refuse you entirely.

A score above 750 is generally considered good. That’s where most banks will approve you without drama and offer decent interest rates. Below 650, you’re in difficult territory — higher rates, stricter conditions, or outright rejection.

How Your CIBIL Score Is Actually Calculated

There are five factors that go into your score. But not all five matter equally, so stop treating them like they do.

Payment history is the big one — it accounts for roughly 35% of your score. This is simply whether you paid your EMIs and credit card bills on time. Every missed payment gets reported to CIBIL by your bank. Miss a ₹3,200 EMI on your HDFC personal loan in March, and it sits on your credit report for years.

The second factor that actually moves the needle is credit utilisation — about 30% of your score. This is how much of your available credit limit you’re actually using. If your SBI credit card has a limit of ₹1,00,000 and your outstanding balance is ₹75,000, your utilisation is 75%. That’s too high. Lenders get nervous. Keeping utilisation below 30% — so using no more than ₹30,000 of that ₹1,00,000 limit — signals that you’re not financially stretched.

The remaining 35% is split across three smaller factors: the length of your credit history (older accounts help), the mix of credit types (having both a secured loan like a car loan and unsecured credit like a credit card is better than having just one), and recent credit enquiries (every time you apply for a new loan or card, a “hard enquiry” is recorded and slightly dents your score).

The Thing Most People Get Wrong

Here’s where a lot of salaried professionals in their late twenties quietly sabotage their own scores without realising it.

Say you’re earning ₹70,000 a month in Bengaluru. You’ve been good with money — no big loans, no defaults. You decide to apply for a home loan and, before that, you check your eligibility on three different bank websites in the same week: SBI, Axis, and ICICI. Each of those checks is a hard enquiry. Three hard enquiries in seven days sends a quiet signal to CIBIL that you’re suddenly hungry for credit. Your score can drop by 10 to 25 points just from that.

The fix is simple: check your own score first (checking your own score is a “soft enquiry” and doesn’t affect it), decide which one or two lenders make the most sense, and apply only there.

What Actually Moves Your Score Up

If your score is sitting at 680 and you want it at 750 within a year, the two levers worth pulling are:

First, pay everything on time — without exception. Set up auto-debit for your credit card’s minimum due at the very least. A single missed payment on a ₹500 outstanding balance can drop your score by 50 points. It’s not about the amount; it’s about the pattern.

Second, bring your credit card utilisation down. If your total credit limit across cards is ₹1,50,000, keep your monthly spending billed to those cards under ₹45,000. If that’s hard because you put everything on the card, ask your bank to increase your credit limit — that lowers utilisation without you spending less.

Do both consistently for 6 to 12 months, and a 680 can comfortably become a 740+.

Frequently Asked Questions

Does checking my own CIBIL score reduce it?

No. Checking your own score is called a soft enquiry and has zero impact on your score. You can check it as often as you want. Only when a bank or lender checks your score — after you’ve applied for credit — does it register as a hard enquiry and slightly affect your score.

How long does a missed payment stay on my CIBIL report?

Negative information, including missed EMIs and defaults, typically stays on your CIBIL report for seven years from the date it was reported. Paying the overdue amount closes the account but doesn’t erase the history.

What CIBIL score do I need for a home loan?

Most major banks — SBI, HDFC, ICICI — prefer a score of 750 or above for home loans. You may still get approved with a score between 700 and 749, but expect a slightly higher interest rate. Below 650, most lenders will decline or ask for a co-applicant.

Can I have a CIBIL score of zero?

Yes. If you’ve never taken a loan or owned a credit card, you have no credit history and your score shows as -1 or “NH” (No History). This isn’t bad — it just means lenders have nothing to judge you on. Getting a secured credit card or a small personal loan and repaying it cleanly is the fastest way to build a score from scratch.

Does my salary affect my CIBIL score?

No. Your income, savings, or investments don’t appear in your CIBIL report and have no direct effect on your score. CIBIL only tracks how you borrow and repay. That said, lenders look at your income separately when deciding your loan eligibility — the maximum amount they’re willing to lend you.
