Your credit score is a three-digit number that determines your creditworthiness and how lenders generally assess your profile as a borrower. This is why it plays a significant role in your financial life when you apply for a home loan. Banks and NBFCs scrutinise this number very carefully.

Your credit score determines whether your loan will be approved and what interest rate you will pay. The difference between a good credit score and a poor one can result in lakhs more in interest over the loan tenure. A small improvement in your CIBIL score can help you save significantly.

In this guide, we will take a closer look at how the credit score directly impacts the interest rates offered to you. We will also learn what strategies you can use to improve your CIBIL score.

Key Takeaways

  • CIBIL scores can directly affect interest rates.
  • Lenders generally offer the most competitive rates to people with a CIBIL score of 750 and above, and reject or offer less favourable terms if the credit score is below 650.
  • A credit score is calculated using factors such as payment history, credit utilisation, credit mix, and creditworthiness.
  • A high credit score can save you lakhs in interest payments.
  • Credit scores help banks determine risk, and a higher score means less risk.

What is a Credit Score and How is It Calculated?

Your credit score represents your creditworthiness. In India, credit scores generally range from 300 to 900. Credit bureaus calculate these scores based on your credit behaviour.

Your score is calculated based on:

  • Your payment history
  • Credit utilisation
  • Length of credit history
  • Credit mix
  • Recent credit inquiries

How are Credit Score and Interest Rate Related?

Banks use credit scores to assess lending risk. A higher score indicates responsible credit management, which translates into better interest rates. A lower score signals higher risk, resulting in higher rates or rejection.

Credit Score Ranges and What They Mean for Home Loans

Different credit score ranges have different implications for home loan approval and interest rates.

  • Excellent (750 - 900): Most banks will approve your application without hesitation. You can qualify for the best interest rates available.
  • Good (700 - 749): Most banks are more likely to approve your application. You still qualify for competitive interest rates.
  • Fair (650 - 699): A few banks will approve your application. Those who approve you may offer higher interest rates. NBFCs may be more flexible but usually charge higher rates.
  • Poor (Below 650): Most traditional banks will reject your application. You might only qualify for loans from NBFCs at significantly higher interest rates.

Note: In addition to the credit score, applicants also need to meet other eligibility criteria set by the lenders to ensure approval.

What a Rate Cut Actually Does to Your EMI

Here’s an example of how a small difference in rates can impact the amount you pay:

How Different Lenders View Credit Scores

Traditional banks typically require a minimum credit score of 650 to 700. Scores above 750 are likely to get the best offers. NBFCs are more lenient and may grant loans to people with a score of 600, but at a much higher rate.

Strategies to Improve Credit Score Before Applying for a Home Loan

If your credit score is below 750, you should work on it and then apply to get a home loan. Even improving by 50 points can save a lot of money. The following are some of the steps that you can take:

  • Pay All Bills on Time: Payment history is the most important factor. Set up automatic payments so that you never miss a payment.
  • Reduce Your Credit Utilisation: Aim to keep your credit utilisation below 30%. Repay all dues on time or request a credit limit increase.
  • Maintain a Diverse Credit Mix: Having different credit types demonstrates responsible credit management.
  • Limit New Credit Applications: Each loan application triggers a hard inquiry that lowers your score. Avoid applying to multiple lenders at the same time, since your score may drop significantly.
  • Check Your Credit Report for Errors: When you get your credit report, review it carefully for any errors. If you find any, dispute them immediately.

Timeline for Credit Score Improvement

It can take some time to improve your credit score. You can look forward to this:

  • Consistent effort can lead to significant improvements in 3-6 months.
  • Major changes typically require 6-12 months.

Conclusion

Your home loan interest rate is largely based on your credit score. A better score makes you eligible for lower interest rates and may save you a lot of money throughout the period of your loan.

Before submitting a home loan application, verify your credit score and make some efforts to improve it where needed. In case your score is lower than 750, take 6 to 12 months to work on it and then apply. Before seeking a loan, it is good to ensure that you settle all your bills within the due dates and clear any outstanding debts.
