How is a credit limit decided?
Two people earn the same salary. One is offered eighty thousand, the other twenty-five. Neither was told why. Here is what actually goes into that number.
A credit limit feels arbitrary from the outside. It arrives as a number, with no explanation, and it is rarely the number you expected. It is not arbitrary. It is the output of an assessment, and the inputs are reasonably well understood.
Income sets the ceiling, not the number
Income is the starting point, but it is a ceiling rather than an answer. What a lender is really calculating is how much of your income is already spoken for. EMIs, rent, existing card balances, anything that has to be paid before you get a choice about it.
Someone earning eighty thousand a month with four existing loans has less room than someone earning sixty thousand with none. That is the first reason two similar salaries produce different limits.
A higher salary does not automatically mean a higher credit limit. What matters is how much of that salary is already committed.
The other six things in the calculation
- Credit score and history. Not just the number, but how long the file goes back.
- Repayment record. Whether you have paid on time, and what happened during any month you did not.
- Existing limits elsewhere. A lender looks at your total available exposure, not just theirs.
- How you use what you have. Someone who routinely uses cards close to the limit reads differently from someone who uses a third.
- Employment and income stability. How long you have been in the same job or business.
- Your relationship with the lender. A bank already receiving your salary knows more than a new one does.
Why two similar incomes get different limits
| PERSON A | PERSON B | |
|---|---|---|
| Monthly income | ₹80,000 | ₹80,000 |
| Existing EMIs | None | ₹22,000 |
| Credit history | Six years, no misses | Eight months, one late payment |
| Existing card limits | ₹60,000, uses a third | ₹2,00,000, usually near the limit |
| Banking relationship | Salary account with the lender | New customer |
Same income. Very different picture. A lender extending credit to Person B is taking a materially different risk, and the limit reflects that.
Worth knowing
None of this is a judgement about the person. Someone with an excellent habit and a thin file often gets a lower first limit simply because there is not enough record to read yet.
