Is a credit card or overdraft usually cheaper?
The cheaper option is the one with the lower total cost over the time you will actually borrow, not the one with the easiest application or the largest limit. An arranged overdraft charges interest when the current-account balance goes below zero. A credit card charges according to the card agreement and may avoid purchase interest where the statement balance is paid in full by the due date.
MoneyHelper’s overdraft guide explains that an overdraft is borrowing and can be an expensive way to stay in debt. Its credit-card guide explains the different card types and the need to compare borrowing options.
For a small gap lasting days, convenience may make an overdraft practical even when its APR is higher. For a planned purchase repaid over several months, a suitable card may cost less. Neither should fund a recurring budget deficit without a plan to fix the underlying shortfall.
Which numbers should you compare?
Collect the arranged-overdraft interest rate, credit-card purchase APR, any promotional rate and its end date, transfer or cash fees, annual fees, late-payment charges and the amount you expect to borrow. Then calculate the cost for a realistic repayment period.
| Question | Credit card | Arranged overdraft |
|---|---|---|
| When does interest start? | Depends on transaction and whether the statement is cleared | Normally while the account is overdrawn |
| Required repayment | At least the contractual minimum | No fixed instalment, but incoming money reduces the balance |
| Common extra costs | Cash, transfer, late or annual fees | Interest and possible charges outside the arranged limit |
| Main behaviour risk | Paying only the minimum | Salary repeatedly disappearing into the overdraft |
MoneyHelper’s borrowing-options tool is a useful independent cross-check. Provider examples must be read with the full terms because representative APR does not guarantee the rate offered to one applicant.
What does a credit card vs overdraft worked example show?
Assume £1,000 is borrowed for 90 days and no extra fee applies. One arranged overdraft charges an illustrative 39.9% effective annual rate. One credit card charges an illustrative 24.9% purchase APR and interest starts immediately for this simplified comparison.
Using a rough daily-interest estimate, the overdraft cost is about £1,000 × 39.9% × 90 ÷ 365 = £98.38. The card cost is about £1,000 × 24.9% × 90 ÷ 365 = £61.40. The card is around £36.98 cheaper in this simplified scenario.
Real statements may compound interest, use different daily rates, apply interest-free purchase periods, and charge fees. The example therefore demonstrates the comparison method rather than quoting a live product. Check the exact agreement and use MoneyHelper’s overdraft explanation before deciding.
When can a credit card be the better option?
A credit card can be preferable when the rate is lower, the borrowing has a clear purpose, the repayment plan clears the balance before a promotion expires, and the borrower can make at least the required payment every month. Paying the full statement balance on a standard purchase card can also avoid purchase interest where the agreement provides an interest-free period.
Cards can provide useful purchase protections in some circumstances, but protection rules do not make unaffordable borrowing safe. Cash withdrawals on a card are commonly treated differently from purchases and may attract fees and immediate interest. Balance-transfer offers can also have transfer fees and revert rates.
The MoneyHelper credit-card guide recommends comparing borrowing options and using eligibility tools that do not mark the credit file where possible. Avoid repeated full applications. A lower advertised rate is not useful if the credit limit is insufficient, the actual offered rate is higher, or the monthly repayment is unaffordable.
When can an arranged overdraft be the better option?
An arranged overdraft can suit a small and genuinely temporary mismatch, such as a direct debit leaving shortly before salary arrives. It is already linked to the current account, incoming money automatically reduces the amount owed, and there may be no separate minimum-payment date.
The danger is that an overdraft can become invisible long-term debt. When salary arrives into an overdrawn account, the account may only return briefly toward zero before normal spending pushes it negative again. A facility intended as a buffer can then become permanent borrowing at a high rate.
Stay within the arranged limit, check whether the bank can reduce or remove the limit, and set a date to return the account to credit. MoneyHelper’s arranged-overdraft guidance notes that cheaper borrowing methods may be available. An unarranged overdraft or refused payment can create different consequences, so do not assume all negative balances are priced identically.
What should you do if neither option is affordable?
Do not use one form of credit simply to keep another account from defaulting without first reviewing the whole budget. Contact the lender early, explain the financial difficulty and ask what support is available. Priority bills such as housing, energy and essential taxes may need attention before unsecured borrowing.
Cancel non-essential spending, stop new card use, list every balance and interest rate, and work out what remains after essential living costs. Paying the most expensive non-priority borrowing first can reduce interest, but only after protecting priority commitments and maintaining agreed payments where possible.

Seek help promptly where repayments are being missed, the overdraft never clears, cash withdrawals are funding bills, or borrowing is being used for food and utilities. A credit comparison cannot solve an income shortfall on its own.
Frequently asked questions
Is an overdraft cheaper than a credit card?
Sometimes, particularly for a very short gap, but many overdrafts have high rates. Compare the actual rate and borrowing duration.
Does a credit card charge interest immediately?
It depends on the transaction and agreement. Purchases may have an interest-free statement period when paid in full, while cash transactions often differ.
Does using an overdraft affect credit history?
Lenders may consider overdraft use and conduct. Persistent use or exceeding the arranged limit can indicate financial stress.
Should I use a card to clear an overdraft?
Only after comparing total costs, fees and repayment dates. Moving debt without changing repayment behaviour can postpone rather than solve the problem.
Where can I get free debt help?
Use MoneyHelper’s debt-advice locator or another recognised free debt-advice provider, especially before taking secured consolidation credit.
