A credit score in the 600s feels like a closed door. But the mechanics of credit scoring mean that consistent positive behaviour starts reflecting in your score within 30–90 days. Here is a systematic, actionable plan to improve your score in a quarter.

Week 1: Get Your Credit Report and Fix Errors

You are entitled to one free credit report per year from each credit bureau — CIBIL, Experian, Equifax, and CRIF Highmark. Download your CIBIL report from cibil.com. Look for: accounts you do not recognise (identity theft), loans marked "Settled" that you paid in full, incorrect personal details, or enquiries you did not make. Dispute errors online — CIBIL must resolve disputes within 30 days.

Important: "Settled" loans — where you negotiated a lower payoff — are very damaging to your score and can persist for up to 7 years. A "Closed" account (paid in full) is neutral or positive. If a lender incorrectly marked your account as Settled, raise an immediate dispute with documentary proof.

Month 1: Pay Every Due on Time

Payment history constitutes 35% of your credit score — the largest single factor. Set up NACH mandates or automated payments for every EMI and credit card due date. Missing even one payment is worse than having a low score; paying on time consistently is the fastest rebuilder.

Month 1–2: Reduce Credit Card Utilisation Below 30%

Credit utilisation — the percentage of your credit card limit you are using — accounts for 30% of your score. If your credit limit is ₹1,00,000 and your balance is ₹70,000, your utilisation is 70% — damaging to your score. Pay down balances to bring utilisation below 30%. If possible, request a credit limit increase without spending more, which automatically lowers your utilisation ratio.

Month 2–3: Do Not Apply for New Credit

Every loan or credit card application triggers a hard enquiry, which drops your score by 5–10 points and stays on your report for 2 years. During your credit recovery period, do not apply for any new credit products. If you need credit, explore pre-approved offers from your existing bank — these use soft enquiries that do not affect your score.

The 90-Day Outcome

Borrowers who fix report errors, pay all dues on time, and reduce credit utilisation consistently see 40–80 point improvements within 90 days. Moving from 620 to 680–700 significantly improves your loan approval probability and can reduce your interest rate by 3–5 percentage points on a personal loan application.
