How to Compare UK Current Accounts With Overdrafts
An overdraft is short-term borrowing attached to a current account. A useful comparison uses the same negative balance and number of days across providers, because an EAR on its own does not show what you will actually pay.
FCA rules make overdraft pricing easier to compare
The FCA requires personal current-account overdraft charging structures to be simple and transparent and generally requires charges to be expressed as interest rates rather than a mix of daily and fixed usage fees. The rules also stop a bank charging a higher interest rate for an unarranged overdraft than the arranged rate that applies to that customer.
That does not mean every bank charges the same rate. Providers still set their own overdraft interest and can offer interest-free buffers or different rates for particular accounts. Eligibility and the limit offered are also individual lending decisions.
Compare the actual offer you receive rather than only the account's representative rate. An overdraft advertised at a representative EAR can still produce a smaller, larger or zero approved limit for you depending on credit and affordability checks.
Translate EAR into pounds using the same scenario
NatWest currently shows a representative 39.49% EAR variable on its Select account. Its own illustration says using a £500 arranged overdraft costs about £3.24 for seven days, £13.87 for 30 days and £28.13 for 60 days.
Lloyds Classic currently shows a lower representative 29.9% EAR variable, with no interest-free amount on that standard account. The difference is material only when converted into the way you borrow. A customer who never uses the overdraft pays no overdraft interest, while someone who spends much of each month below zero can pay repeatedly.
For a fair comparison, choose a balance such as £500 and model seven, 30 and 60 days. Then repeat with your likely worst month. The lower EAR normally helps, but an interest-free buffer on another account can beat a lower rate for very small, short dips. A one-percentage-point EAR difference matters less on a £50 overdraft used for two days than on a £1,000 overdraft used for most of the month. Keep the balance and duration fixed when comparing providers, then repeat the calculation with your own worst realistic month so the lower quoted rate is not given more importance than it deserves.
Arranged and unarranged use can have different consequences
An arranged overdraft is agreed in advance up to a limit. An unarranged overdraft arises when the account goes below zero without enough agreed facility, or a payment takes you beyond the arranged limit. Banks can decline payments rather than allow unarranged borrowing.
NatWest currently charges interest on unarranged borrowing on standard adult accounts and also publishes a monthly charging cap that includes certain unpaid transaction fees. Lloyds Classic states that it does not charge unarranged overdraft interest, fees or charges, but a payment can still be refused and missed payments can damage your credit record.
The important comparison is therefore not simply "does the bank charge?". Check whether payments are likely to be returned, whether alerts arrive in time to move money, and what happens to essential Direct Debits when the balance is insufficient.
Interest-free buffers can be valuable for predictable shortfalls
Student and graduate accounts can have large interest-free portions, while premium or specialist accounts may have smaller buffers. NatWest's Graduate account currently offers an interest-free arranged overdraft of up to £3,250 in the first year after graduation, reducing in later years, subject to eligibility.
A buffer is valuable only for the portion inside it. If an account gives £1,250 interest-free but you use £2,000, the remaining £750 can still be charged at the standard overdraft rate. Do not describe the whole overdraft as free when only a band is interest-free.
Also treat the limit as temporary credit, not income. Banks can review overdrafts and they are normally repayable on demand. Build a plan to return the account to credit rather than budgeting permanent spending around the full limit. Check whether the buffer applies automatically or only after approval, and whether the bank can review it. A buffer that depends on student, graduate or premium-account status can disappear when that status changes, so put any scheduled reduction date in your calendar instead of treating the interest-free amount as permanent.
When repeated overdraft use means the account is not the problem
If you are overdrawn for a few days before payday, comparing account pricing can save money. If you remain overdrawn most of the month, the more important question is whether the overdraft has become long-term debt.
A £500 balance used for 30 days at NatWest's current illustration costs about £13.87. Repeat a similar pattern for many months and the annual cost becomes meaningful. A lower-rate account can help, but it does not solve a persistent cash-flow deficit.
Use low-balance alerts, move bill dates where practical and review fixed spending. If borrowing is structural rather than occasional, compare alternative debt options or free debt guidance instead of repeatedly switching current accounts for a marginal EAR improvement. If you cannot clear the overdraft after salary arrives, record the balance one day after payday for several months. A pattern where the account returns only briefly to credit, or never does, is a sign that the borrowing has become structural. In that case, a cheaper overdraft can reduce cost but should sit alongside a repayment plan rather than replacing one.
BankOfferScout editorial view
The editorial lens on Current Accounts With Overdraft Options is deliberately practical: model the likely amount and duration of borrowing, then judge annual account cost, everyday usability and borrowing exposure. This reduces the chance that a temporary headline benefit dominates a decision it should not control.
The editorial test for Current Accounts With Overdraft Options is whether the choice still works under normal behaviour. The strongest option is not necessarily the one with the loudest rate, reward or bonus. A better fit is the one that still works after allowing for borrowing more often or for longer than expected, with recurring costs and benefits translated into a common period.
The last step is freshness. Confirm interest or arranged-overdraft pricing on the provider tariff, eligibility page and current account terms; where a scheme, tax or regulatory rule matters, use the relevant payment-system or regulatory source as well. The final application, transfer or switch should always use current information.
Sources and related guides
Overdraft rules and product examples were checked on 30 September 2026 against the FCA Handbook and current NatWest and Lloyds pages. Future updates should recheck EAR, interest-free buffers, monthly caps and the provider's pound-cost examples. Keep representative pricing separate from the personal limit and rate actually offered to an applicant.

Do not copy a bank's monthly cap or unpaid-item fee into another provider section. If an account-specific rate varies by customer, describe the published representative rate as an example rather than a guaranteed personal price.
