How Your CIBIL Credit Score Is Calculated — The Complete 2026 Guide

About 80% of loans approved in India go to people with a score above 750. Below 700, you may get a higher interest rate or face rejection. A 50-point score difference can mean 1–2% higher home loan rate — on a ₹50 lakh loan over 20 years, that can be roughly ₹6–12 lakh extra interest.

Updated from Jan 2025 onward, many credit profiles refresh more frequently than the older “once a month” mental model — check your report after big life changes (new loan, closure, limit change).

• 1) Payment history — 35% weight: The single most important factor. Miss one EMI by 30 days → score can drop ~30–50 points immediately; 90+ days late can drop 100+ points. One missed payment in three years is a smaller blemish than repeated misses. Pro tip: autopay the minimum due, then pay the full bill manually so you never miss the due date.
• 2) Credit utilisation — 30% weight: How much of your credit limit you use. ₹40,000 of ₹1,00,000 limit = 40%. Ideal: below ~30%. Above ~50% can hurt significantly. Pro tip: ask your bank to increase the credit limit — spending stays the same but utilisation falls.
• 3) Credit mix and duration — 25% weight: Mix means both secured (home loan, car loan) and unsecured (credit card, personal loan) can help when reported cleanly. Duration means older accounts boost your score — never close your oldest credit card if you can keep it fee-free (even unused).
• 4) New credit inquiries — 10% weight: Every loan application can create a hard inquiry; each hard inquiry may drop the score ~5–10 points. Five loans in one month is risky. Checking your own score is a soft inquiry — no impact. Pro tip: apply for one loan at a time and space applications (many people use ~6 months as a practical gap).

From Dec 2025, RBI’s push for uniform credit reporting formats aims to make disputes and corrections more predictable — treat “reporting errors” as fixable, but always keep proof (NOCs, bank emails, payment receipts).

• Score ranges and real impact: 300–549 very poor (many applications rejected); 550–649 poor (high rates); 650–699 average (limited options); 700–749 good; 750–799 very good (best rates often start here); 800–900 excellent (room to negotiate).
• Things that usually don’t affect score: your income/salary, checking your own score, savings account balance, age/gender, and investments.

• Day 1: Pay all overdue bills immediately.
• Day 30: Utilisation improves as you pay dues and reduce revolving balances.
• Day 45: Check your CIBIL report for errors (you can access bureau reports periodically; keep PDFs).
• Day 60: Dispute inaccuracies with evidence (plan for a ~30-day resolution cycle in many workflows).
• Day 90: Your score starts reflecting sustained improvements if new negatives stop.
