One is a facility you dip into; the other is a loan that closes. The cheaper option on paper is the one people carry for years without noticing.

An overdraft charges interest only on what you use, only for the days you use it. That makes it cheaper on paper and, for a lot of people, more expensive in practice — because nothing ever forces it to close.
A salary overdraft is a standing limit on your salary account that you dip into and repay as you like, with interest charged daily only on what you have used. A salary advance is a fixed loan with a fixed end date. The overdraft is cheaper for short, occasional use and quietly more expensive for anyone who never brings it back to zero.
Your bank sanctions a limit against your salary account — often two to three times your monthly salary. The limit sits there whether you use it or not. Spend below your balance and nothing happens; go past it and you are into the overdraft, and interest begins on that amount from that day.
Interest is calculated daily on the used portion only. Use ₹10,000 for six days and you pay six days of interest on ₹10,000, not a month's interest on the sanctioned limit. When your salary lands, it automatically reduces the outstanding.
That mechanism is genuinely elegant for short gaps. If you are ₹8,000 short for the last four days of the month, an overdraft is close to the perfect instrument, and far cheaper than any loan.
A loan has an amortisation schedule. Every EMI reduces the principal whether you think about it or not, and one day the loan is finished.
An overdraft has no such mechanism. Your salary arrives and reduces the balance; your spending pushes it back up. If you never deliberately clear it, the outstanding drifts along month after month, quietly accruing interest. People commonly discover they have been carrying an overdraft balance for two or three years, having intended it as a two-week bridge.
The second issue is that a salary account with a permanent overdraft balance reads poorly to other lenders. It suggests income does not cover outgoings, which is exactly what it means.
| Salary overdraft | Advance salary loan | |
|---|---|---|
| Structure | Standing limit, use as needed | Fixed amount, fixed schedule |
| Interest | Daily, on the used amount only | On the full amount for the tenure |
| Rate | Usually lower | Usually higher |
| Repayment discipline | None — entirely up to you | Built in |
| Does it end? | Only if you make it | Yes, on a known date |
| Availability | Salary account holders, by invitation | Anyone who qualifies, at many lenders |
| Renewal | Annual review; can be reduced or withdrawn | Not applicable |
| Best for | Small, short, occasional gaps | A defined need with an end date |
Take the overdraft if your gaps are small, short and irregular — a few days before payday, a few times a year. It is cheaper for that pattern than any loan, and you pay nothing when you are not using it.
Take the advance if you have a defined amount to cover and want it gone. The forced schedule is not a limitation; for most people it is the main benefit. It is also the better choice if you know yourself well enough to admit that an open facility will stay used.
Take neither if the shortfall is monthly and structural. Neither product fixes that, and both will quietly make it worse. Consolidation or a plain budget review is the honest answer there.
Salary overdrafts are usually extended by invitation to account holders with a good salary-credit history — often after a year or more. If you have not been offered one, check your net banking; many people have a pre-approved limit sitting unused. If not, a salary advance is the accessible option, and the eligibility checks tell you where you stand.
Whichever you take, be clear about the cost. The rates page covers what to ask, and the amount page covers how much you can sensibly borrow.
Both instruments have their place. The advance salary loan guide covers the advance in full, including the situations where neither product is the answer and the budget is.
Q1. Is a salary overdraft cheaper than a salary advance?
For short, occasional use, clearly yes — interest is charged daily only on what you draw. Over a balance you carry for months, the advantage disappears, and the absence of a repayment schedule often makes it more expensive in the end.
Q2. How is overdraft interest calculated?
Daily on the outstanding used amount, then charged monthly. Use ₹10,000 for six days and you pay six days of interest on ₹10,000. Nothing is charged when the balance is zero.
Q3. Does an unused overdraft limit affect my loan eligibility?
An unused limit usually has little effect. A consistently used one does — lenders may treat the drawn portion as an obligation, and a permanently overdrawn salary account raises questions about whether income covers spending.
Q4. Can the bank withdraw my overdraft limit?
Yes. Limits are reviewed periodically and can be reduced or withdrawn, particularly if your salary credits stop or your credit profile weakens. It is a facility, not a guarantee, which is worth remembering before relying on it.
Q5. Does using an overdraft show on my credit report?
Usually yes, as a revolving credit line with a limit and a balance. Consistently high usage affects your score in the same way a maxed-out credit card does.
Q6. Can I have both an overdraft and a salary advance?
If your total obligations stay within the lender's ceiling, yes. Whether it is wise is another matter — needing both at once usually points to a shortfall that neither product is designed to solve.
