How Your Bank Actually
Decides Your Loan Rate

When a bank quotes you 16% on a personal loan and your colleague at the same company gets 12.5% from the same bank, that's not luck or favouritism. It's the output of a scoring model that weighs several factors about each borrower. The model is internal and banks don't publish it, but the factors it uses are well understood.

Knowing what goes into the rate gives you something actionable: a list of things you can change before you apply.

The basic formula

Every bank's personal loan rate follows the same structure:

For a personal loan today, the base rate is roughly 8 to 9%. The risk spread is where the 10.5% and the 24% loans diverge. Low-risk borrowers get a small spread. High-risk borrowers get a large one.

The factors that determine your risk spread

CIBIL score: the biggest single factor

A borrower with a score above 800 might get a spread of 2 to 3%. A borrower with a score of 680 might get a spread of 8 to 12%. The difference isn't small. Banks have extensive data showing that default rates climb sharply as scores fall below 700, so they price accordingly.

Your employer and employment type

Banks segment employers into categories internally. Central government employees sit at the top, then state government, then large listed companies, then mid-size private companies, then small private companies, then self-employed professionals, then self-employed business owners. Each category carries a different default risk in the bank's historical data, and rates reflect that.

This is why two people with identical CIBIL scores can get different rates: one works for a listed company, the other works for a small private firm.

Your income level and stability

Higher income reduces risk in two ways. First, a ₹1 lakh EMI is less stressful for someone earning ₹3 lakhs a month than for someone earning ₹80,000. Second, higher earners tend to have more financial cushion during emergencies. Banks reward this with lower spreads.

Income stability matters too. Three years at the same employer is better than six months, even at a higher income. Banks want to see that the income is reliable, not just current.

Existing relationship with the bank

If you have a salary account with the bank, they already know your actual income, spending patterns, and savings behaviour. This information reduces uncertainty for the bank, and they price that lower risk into your loan. Salary account holders at the same bank regularly get rates 1 to 2% lower than walk-in applicants with identical CIBIL scores.

Loan amount and tenure

Larger loan amounts sometimes get lower rates on a percentage basis because the absolute profit margin is higher. A ₹20 lakh loan at 12% generates more revenue than a ₹2 lakh loan at 18%, so banks have some flexibility with larger borrowers.

Longer tenures carry more risk of default over time, so some banks price longer-tenure loans at slightly higher rates.

Debt-to-income ratio

Your total existing EMI burden as a percentage of income tells the bank how much financial stress you're already under. A borrower paying ₹10,000 in existing EMIs on a ₹1 lakh salary is under less strain than one paying ₹40,000. Banks want your total EMI obligations including the new loan to stay below 40 to 50% of your income.

What this means practically

Factor	Unfavourable	Favourable	Rate Difference
CIBIL score	Below 700	Above 800	4 – 8%
Employer type	Small private company	Govt / large listed	1 – 3%
Bank relationship	Walk-in customer	Salary account holder	1 – 2%
Income level	₹30,000/month	₹1,50,000/month	0.5 – 2%
Existing debt	High EMI burden	Low or no existing EMIs	1 – 3%

The total potential difference between the worst and best position on these factors is 8 to 18 percentage points. That's the difference between 10.5% and 28% on the same bank's personal loan product.

How to use this to get a better rate

Most of these factors can't be changed overnight. But a few can be optimised before you apply:

• Apply after moving your salary to the lender's bank. Three to six months of salary history is often enough to qualify for their salary account benefits.
• Pay down credit card balances before applying. This improves your CIBIL score and reduces your debt-to-income ratio simultaneously.
• Apply when you have no other recent loan applications. A clean enquiry history signals that you're not desperate for credit.
• Negotiate using a competing offer. If you have a written offer from Bank B at a lower rate, Bank A has to respond. The rate isn't always final until you push back.
