Improvement is boring and slow. Indian bureaus describe the inputs to their models but publish no weights and no timeline, so anyone promising you “+50 points in 30 days” is selling something. What is public and worth acting on fits on one line: repay on time, use a modest share of your limits, keep accounts old, apply rarely — and check the report so nothing false sits there.
1. Repay every due, on time
Payment history is the first thing every bureau names. A late EMI is not just a fee; it becomes a days-past-due entry that lenders read for years. Set standing instructions so a busy month does not become a report entry, and remember co-signed, guaranteed and joint accounts: you are equally liable, and the other person's missed payment lands on your file.
2. Watch credit utilisation
Utilisation is outstanding ÷ limit, per card and overall. CIBIL lists high utilisation among its key factors and says it may negatively impact the score; no bureau publishes a safe number, so treat it as a dial you control. Our calculator shows the ratio and the paydown to a target you set yourself. Closing a card you do not use cuts your available limit and usually pushes the ratio up, not down.
3. Keep the mix and the age
A blend of secured debt (home, auto) and a small amount of unsecured credit reads better than a wall of personal loans. Account age matters, so an old, well-behaved card is an asset — do not close it to tidy up. Do not take a loan you do not need just to “build” a score.
4. Apply in moderation
Each application leaves a hard enquiry. Bureau guidance treats a cluster of recent enquiries as rising debt appetite. Space applications out and start with the lender most likely to say yes.
5. Read the report, not the score app
Claim your free full credit report from each bureau once a year and read the account list: an account you never opened, a balance you cleared, a loan shown open after closure, a default a lender admitted was an error. Anything inaccurate is a dispute — free, and on a clock. See how to dispute a wrong entry for the 30-day rule and the ₹100-per-day entitlement.
What does not work
- Paying a third party to “fix” a score — corrections are free at every bureau.
- Closing your oldest card, which trims account age and available limit.
- Opening a new card while utilisation is already high.
- Waiting for a bureau to spot an error: bureaus report what lenders give them; only you can catch a wrong entry.
Realistic timelines
A successfully disputed error can move within a dispute cycle (30 days by rule). A cleared balance needs the lender to report it, then the bureau to update — the RBI reporting regime runs on four reference dates a month, so expect weeks. An accurate missed payment stays in the record no matter what you do next.
