Borrowing and credit

What is an arranged overdraft?

Quick definition: An arranged overdraft is an overdraft limit agreed with the bank in advance, allowing borrowing through a current account up to that limit.

At a glance

  • The bank agrees the limit before it is used.
  • Interest may be charged when the overdraft is used.
  • The limit can be reviewed, reduced or withdrawn under the terms.
  • It is different from an unarranged overdraft.

Explain it simply

An arranged overdraft is a borrowing limit your bank agrees before you use it. If your current account runs out of your own money, you may be able to borrow up to that agreed limit. For example, if the limit is 250 pounds, the bank may allow payments that take the account below zero up to that amount. It can still cost money, and the bank can set rules about how it is used and repaid.

Student explanation

Arranged overdrafts are planned borrowing facilities attached to current accounts. They can help manage temporary timing gaps, such as a bill due the day before wages arrive. The cost is often shown using an interest rate such as EAR, and the actual cost depends on how much is borrowed and for how long. Students should understand that an arranged overdraft may appear in the available balance, but it is still debt. Providers may assess eligibility and can change limits under the account terms.

Professional explanation

An arranged overdraft is an agreed credit limit on a current account, established through underwriting, eligibility and customer acceptance processes. It permits debit balances up to the approved limit, subject to terms, pricing and ongoing monitoring. Conduct requirements include clear pre-contract and ongoing information, cost transparency, alerts, treatment of financial difficulty and responsible lending considerations. Operationally, arranged overdrafts interact with payment authorisation, available balance presentation, credit bureau reporting, collections and limit management. They should be distinguished from unarranged overdrafts, where borrowing occurs without prior agreement or outside the approved limit.

UK example

Mina has an arranged overdraft of 300 pounds and uses 45 pounds for two days before her wages arrive.

Why it matters

Arranged overdrafts can be useful for short gaps, but users need to know the cost and not mistake the limit for their own money.

Common misunderstanding

An arranged overdraft is agreed borrowing, but it is not guaranteed to stay available forever or to be cost-free.
