You have 50 manat in your account, but you need to make a payment of 70 manat — and the transaction still goes through. This is the work of an overdraft: the bank lets you spend more than the amount in your account. Convenient as it looks, an overdraft is essentially a short-term loan and can be expensive if not used properly. In this article we explain how an overdraft works, its interest, its limit, and how to use it responsibly.
What is an overdraft?
An overdraft is a short-term credit line that lets you spend up to a certain limit even after your account balance reaches zero. That is, your account goes "into the negative," and you cover this negative amount later, when income comes in. It is often tied to a salary card and is meant to bridge an unexpected short-term cash shortfall.
How does it work?
The mechanism is simple: the bank sets you an overdraft limit (for example, up to 50% of your monthly salary). Within this limit, payments keep going through even if your balance runs out. When money comes into your account — usually at the next salary — the amount you used is automatically covered and the limit is restored. So the overdraft works like "revolving" credit: use, repay, use again.
How is interest calculated?
Overdraft interest is charged only on the amount you use and only for the days you keep it in the negative — not on the whole limit. That is, if you have a 1000 manat limit but use only 100 manat and cover it 3 days later, interest is charged only on those 3 days of the 100 manat. This makes an overdraft relatively cost-effective in the short term, but its annual interest rate is usually higher than that of an ordinary consumer loan. This is why staying in the negative for a long time is expensive.
The difference between an overdraft, a credit card, and a loan
| Criterion | Overdraft | Credit card | Consumer loan |
|---|---|---|---|
| Term | Very short | Flexible | Fixed term |
| Interest-free period | Usually none | Often present | None |
| Interest is on | The amount used | The outstanding debt | The whole amount |
| Typical use | Short cash gap | Everyday purchases | Planned large expense |
Rules for responsible use
- Use it only for urgent, short-term gaps — in an amount you will cover by the next salary.
- Cover it as soon as possible. Since interest accrues every day, delay increases the cost.
- Do not use the whole limit. A permanently near-zero balance shows a lack of planning.
- Monitor your account. Using it without knowing you are in the negative leads to unexpected interest.
What are the risks?
The main risk of an overdraft lies in its convenience: since payments go through even when your account is in the negative, you may not feel that you have gone into debt. Over time the overdraft comes to feel like your "normal" balance, and each salary only just covers it. In addition, if you try to exceed the limit, some banks reject the transaction while others charge an additional penalty. An overdraft is also assessed as part of your debt burden and can raise your debt-to-income ratio — which in turn affects your future loan applications.
Conclusion
Used correctly, an overdraft is a useful tool that comfortably bridges short-term cash gaps, but when it turns into a permanent source of debt it becomes an expensive trap. Keep it only for short gaps you will cover quickly, and do not see the limit as a substitute for planning. If you experience a continuous shortfall, consider replacing the overdraft with a cheaper and planned consumer loan.
