What actually moves the number
| Factor | Approx. weight | What it means practically |
|---|---|---|
| Payment history | ~35% | Every missed or late EMI/credit-card payment is remembered for years |
| Credit utilisation | ~30% | Balance carried vs. total credit limit — lower is better, ideally under 30% |
| Credit history length | ~15% | Older accounts in good standing help; this is why closing your oldest card can hurt |
| Credit mix | ~10% | A mix of secured (home/auto loan) and unsecured (credit card) credit, handled responsibly |
| Recent hard inquiries | ~10% | Multiple loan/card applications in a short window signal credit-hungry behaviour |
Common mistakes that quietly hurt your score
- Closing your oldest credit card — this shortens your average credit history and can raise your utilisation ratio on remaining cards.
- Applying for multiple loans/cards in a short window — each hard inquiry has a small negative effect, and several together compound it.
- Only paying the minimum due — this keeps utilisation high even though the account shows as “paid,” and interest accrues on the rest.
- Being an unaware co-signer/guarantor — the primary borrower’s missed payments can affect a co-signer’s score too.
- Never checking your report for errors — incorrect entries (a loan that isn’t yours, a wrongly marked late payment) are more common than people expect and can be disputed.
A realistic improvement timeline
| Action | Typical time to see effect |
|---|---|
| Paying down utilisation before statement date | 1 billing cycle |
| Correcting an error on your credit report | 30-45 days after dispute resolution |
| Recovering from a single missed payment (if resolved quickly) | A few months, with consistent on-time payments after |
| Recovering from a default/settlement | Multiple years of clean repayment history |
Before applying for a large loan (home/car)
- Check your score at least 2-3 months in advance, not the week you plan to apply.
- Avoid opening new credit lines or making large purchases on existing cards in that window.
- Pay down revolving balances to under 30% utilisation before the lender pulls your report.
Bottom line
Payment history and utilisation are the two levers that matter most, and utilisation is the one you can influence fastest. Treat your credit score as a maintained habit, not a one-time fix.
