How your credit score affects your loan interest rate

When a lender prices your loan, the first number they look at is your credit score — a three-digit summary of how you have handled debt in the past. The score typically ranges from 300 to 900, and where you fall on that band decides not just whether your loan is approved, but how much it costs you.

What lenders see in each score band

• 760 and above — treated as prime. Best published rates, fastest approvals, higher negotiating power on processing fees.
• 700 – 759 — comfortably approved. Rates are usually 0.25% – 1% above the best band.
• 650 – 699 — approvable, but expect a rate premium of 1% – 3% or a lower sanctioned amount.
• Below 650 — most large lenders decline; NBFC options exist but at significantly higher rates.

Why the rate difference matters so much

On a ₹50 lakh, 20-year home loan, a 0.5% rate difference changes your total interest by roughly ₹4 lakh. On unsecured loans the swing is larger, because the rate itself starts higher. Over a full tenure, your credit score is quite literally worth lakhs.

What actually moves your score

• Payment history — the single biggest factor. Every on-time EMI and credit-card payment helps; every missed payment hurts for years.
• Credit utilisation — keep card usage below 30 – 40% of your total limit, both per card and overall.
• Age of credit — older, well-serviced accounts help. Avoid closing your oldest card casually.
• Hard enquiries — multiple loan applications in a short window read as credit hunger and pull the score down.
• Credit mix — a healthy blend of secured and unsecured accounts is viewed positively.

Check your score three to six months before you plan to apply for a loan, not after. That window is enough to fix utilisation, clear small delinquencies and correct report errors.

If your score needs work, start with the levers above and give it two reporting cycles. If you already have a strong score, use it — ask competing lenders to match or beat each other's offers before you sign.
