Credit score and your home-loan rate: how lenders price the spread over repo

Rules and rates as of 16 October 2026.

Two people can walk into the same bank in the same week, ask for the same ₹50 lakh home loan, and be quoted different rates. The repo rate is the same for both. What differs is the spread the bank adds on top, and part of that spread is priced on how risky the bank thinks each borrower is. Your credit report is a big input to that judgement.

How a repo-linked rate is built

Since 1 October 2019, every new floating-rate housing loan from a bank has had to be linked to an external benchmark, under the RBI's circular of 4 September 2019. The permitted benchmarks are the RBI policy repo rate, the 3-month or 6-month Treasury Bill yield published by FBIL, or another FBIL market rate. Your sanction letter names the benchmark your loan uses; this article assumes it is the repo rate.

The rate you pay is simple to describe: benchmark + spread. On 7 October 2026 the Monetary Policy Committee raised the repo rate by 25 basis points to 5.50% (RBI press release 2026-2027/1264). So a loan quoted at "repo + 2.50%" carries 8.00% today.

The RBI's Interest Rates on Advances Directions, 2025 for commercial banks (28 November 2025) restate the rules. A bank "is free to decide the spread over the external benchmark", but it must have a board-approved policy setting out the components of the spread, how each is worked out, and the range of spread for each category of borrower. In practice the spread has two kinds of parts:

• Credit risk premium. The part that reflects the risk that you, specifically, will not repay. The Directions describe it as based on a credit risk rating or scoring model, along with factors such as the customer relationship and collateral.
• Other components, such as the bank's operating cost and business strategy. These are set for a loan category, not for you.

The Directions also say neither the business strategy component nor the credit risk premium can be negative.

Where the credit score comes in

No RBI rule says which credit score earns which spread. That is each bank's own policy, set out in its board-approved pricing policy. What the rules do say is that the credit risk premium must come from the bank's risk assessment of you, and your credit report from a credit information company is one of the main inputs. A stronger score usually means a lower premium. A thin or patchy history, late payments, or a high balance on credit cards can push you into a costlier band.

When the spread can change after you sign

This is the part that matters for the next 20 years. Under the 2019 circular, carried into the 2025 Directions:

• The credit risk premium may change only when your credit assessment "undergoes a substantial change", as agreed in the loan contract.
• The other components, including operating cost, can be altered only once in three years. Banks may reduce them earlier for a loan category to retain customers, on grounds that are justified and do not discriminate.
• The Directions add that the spread charged to an existing borrower shall not be increased except on account of a deterioration in that borrower's credit risk profile, backed by a full review of the risk profile.
• The rate must be reset at least once in three months, so repo changes pass through to everyone, whatever their spread.

Two things follow. A poor score at sanction can lock in a higher spread, and an improved score later does not by itself lower it; you have to ask. And a falling score during the loan can, if your contract provides for it, raise your premium. Read the clause in your sanction letter or loan agreement that defines a "substantial change" in credit assessment.

Worked example: two borrowers, ₹50 lakh for 20 years

The spreads here are illustrative, not any bank's rate card. Borrower A is priced at repo + 2.00%, so 7.50%. Borrower B, with a weaker score, is priced at repo + 2.50%, so 8.00%.

EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where P is ₹50,00,000, n is 240 months, and r is the annual rate ÷ 12.

• Borrower A, r = 7.50% ÷ 12 = 0.625% a month: EMI ₹40,280. Total paid ₹40,280 × 240 = ₹96,67,200, so interest is ₹46,67,200.
• Borrower B, r = 8.00% ÷ 12 = 0.6667% a month: EMI ₹41,822. Total paid ₹41,822 × 240 = ₹1,00,37,280, so interest is ₹50,37,280.

Half a percentage point of spread costs Borrower B ₹1,542 more each month and ₹3,70,080 more in interest over 20 years (computed on rounded EMIs), assuming the repo rate never moves. If it does, both move together and the gap stays.

Spread over repo (5.50%)	Loan rate	EMI on ₹50 lakh, 20 years	Total interest
2.00%	7.50%	₹40,280	₹46,67,200
2.25%	7.75%	₹41,047	₹48,51,280
2.50%	8.00%	₹41,822	₹50,37,280
2.75%	8.25%	₹42,603	₹52,24,720

Each quarter-point of spread on this loan adds ₹767 to ₹781 a month, or about ₹1.84 lakh to ₹1.87 lakh of interest over the term.

Your rights on your credit report

The RBI's Credit Information Reporting Directions, 2025 (6 January 2025) give you tools to check and fix the input before a bank prices you:

• A free full credit report, with score, once a year. Credit information companies must give you one free full credit report including your credit score, once in each calendar year (January to December), on request after checking your identity.
• Alerts. Credit information companies must send an SMS or email alert when a lender pulls your report, and lenders must alert you when they report a default.
• A 30-day limit on fixing errors. A complaint must be resolved within 30 days overall: the lender has 21 days to send corrected data, and the credit information company the rest. If it is not resolved within 30 calendar days of your complaint, you are entitled to compensation of ₹100 for each calendar day of delay, paid by whichever of the two caused it.

Before you sign

Ask each bank for the spread, not just the rate, and for the score band it has placed you in. Check the loan agreement for what counts as a substantial change in your credit assessment. These rules bind banks; if you are borrowing from a housing finance company, ask in writing how its rate is set and when it can change.
