Credit Score
What Makes Up Your Credit Score?
Last updated 17 June 2026Key Takeaways
- Five main factors shape your score: payment history, credit utilisation, history length, credit mix, and new credit/enquiries.
- Payment history and credit utilisation matter most — they're the biggest levers.
- History length, credit mix and new credit are supporting factors.
- Your income is not a scoring factor — it matters for loan eligibility, not the score itself.
- Exact weightings aren't published by the bureaus; treat precise percentages with caution.
The Factors That Build Your Score
Your credit score is a summary of your credit report — the record of how you've handled credit. TransUnion CIBIL groups the inputs into a few main factors. Here's what each means and where to go deeper:
- Payment history — whether you've paid your loans and cards on time. This is generally the most influential factor.
- Credit utilisation — how much of your credit limit you're using (keep it below ~30%). The second major lever.
- Credit history length — how long you've held and managed credit. A longer, well-managed history helps.
- Credit mix — the balance of secured and unsecured credit. A supporting factor.
- New credit — recently opened accounts and recent applications (hard enquiries).
Which Factors Matter Most
Although exact weightings aren't published, the consistent guidance across bureau material is a clear hierarchy:
| Factor | Relative weight | Your main lever |
|---|---|---|
| Payment history | Highest | Pay every bill in full, on time |
| Credit utilisation | High | Keep balances well under 30% of limits |
| Credit history length | Moderate | Keep old, good-standing accounts open |
| Credit mix | Lower | Let it develop naturally; don't force it |
| New credit / enquiries | Lower | Apply only when you genuinely need credit |
The practical takeaway: focus your energy on the top two — they move the needle most.
What Does NOT Affect Your Score
- Your income or salary — it isn't part of the score (though lenders assess it for eligibility).
- Checking your own score — that's a soft enquiry and never lowers it.
- Your savings or investments — deposits and assets aren't credit-report data.
Worked Example
This is illustrative. Imagine two people with the same income:
- Person A pays every EMI on time and keeps card utilisation at 15%. Their payment history and utilisation — the two biggest factors — are strong, supporting a healthy score.
- Person B earns the same but often pays late and runs cards near their limit. Despite the identical income, their score is likely lower, because the score reflects behaviour, not earnings.
The lesson: the score rewards how you manage credit, not how much you earn.
Common Mistakes to Avoid
- Chasing one factor while ignoring payment history — nothing outweighs paying on time.
- Assuming a high salary lifts the score — it doesn't.
- Closing old cards — this can shorten history and raise utilisation.
- Applying for lots of credit at once — it clusters enquiries and lowers average account age.
- Trusting "exact percentage" claims — bureaus don't publish them.
Expert Verdict
Don't overthink credit scoring. Five factors matter, but two — payment history and utilisation — do most of the work. Pay everything on time, keep your card balances well below a third of your limits, and let the rest (history length, mix, new credit) take care of itself over time. Everything else is noise, including your income, which affects loan eligibility but not the score.

Frequently asked questions
What are the main factors in a CIBIL score?
Payment history, credit utilisation, credit history length, credit mix, and new credit (recently opened accounts and enquiries). Payment history and utilisation carry the most weight.
Which factor affects my credit score the most?
Payment history is generally the most influential, followed by credit utilisation. The others are supporting factors.
Does my income affect my credit score?
No. Income isn't part of the score, though lenders consider it separately when assessing loan eligibility.
Are the exact factor weightings published?
No. The bureaus describe the factors but do not publish exact percentage weightings, so treat precise figures with caution.
Does checking my own score affect these factors?
No. Checking your own score is a soft enquiry and has no effect on your score.
How quickly can I improve my score?
It depends on the factor. Utilisation can improve within a billing cycle or two; payment history and history length improve gradually with consistent behaviour.
