Loans, Overdrafts and Credit Cards Compared

A man holding a bank card and phone deciding how to pay, with a drawn diagram of £500 splitting into a loan, an overdraft and a credit card on the wall beside him

A personal loan, an overdraft and a credit card all let you use money that must be repaid. That is where the similarity ends.

A loan gives you a lump sum with an agreed repayment schedule. An overdraft lets your current account move below zero. A credit card gives you a reusable limit that can be used for purchases and, usually at a higher cost, cash withdrawals.

The cheapest option cannot be identified from the product name alone. You need to consider the actual rate, fees, repayment pattern and total cost offered to you.

With poor credit, the rates available may be higher and the limits may be lower. You might also be declined. Check affordability before applying and avoid making several full applications within a short period.

What happens to the same £500?

£500borrowed three ways
  • Personal loan

    1. You receive £500 as a lump sum.
    2. You make agreed repayments over a fixed term.
    3. The balance is cleared at the end of the term.
  • Overdraft

    1. Your bank account falls to minus £500.
    2. Interest is normally charged while the account remains overdrawn.
    3. Money paid into the account automatically reduces the amount being used.
  • Credit card

    1. The card provider pays for a purchase costing £500.
    2. The balance appears on your next statement and you must make at least the minimum payment.
    3. Paying only the minimum can keep the debt running for much longer.

These are general characteristics. Individual products and agreements differ. Always read the terms provided by the lender, bank or card issuer.

How a personal loan works

A personal loan provides one amount of money at the start. You then repay it, usually with interest, over an agreed number of months or years.

The repayment is normally fixed, although some loans have variable rates. The payment schedule is designed to clear the balance by the end of the term.

This structure can make budgeting easier because you know:

  • How much you borrowed
  • The normal monthly repayment
  • How many repayments are required
  • The total amount repayable
  • When the agreement should end

A loan may be worth considering for one planned expense where the amount is known and fixed repayments are affordable.

However, a lower monthly payment does not automatically mean a cheaper loan. Extending the term usually means paying interest for longer, so choosing the right repayment term matters. Compare the total repayable and the APR as well as the monthly amount.

You cannot normally reuse money that has been repaid without making another application.

How an overdraft works

An overdraft is borrowing attached to a current account. If the balance falls below zero, the account is overdrawn.

An arranged overdraft has a limit agreed with the bank. An unarranged overdraft happens when the account goes below zero without an agreed facility or moves beyond the agreed limit.

Interest is normally calculated on the amount being used. Under FCA overdraft rules, banks must price arranged and unarranged overdrafts using a single interest rate rather than daily or monthly fees. When wages or other money enter the account, they reduce the overdrawn balance automatically.

This makes an overdraft flexible, but it can also hide how long the debt has been outstanding. There is no normal final repayment date forcing the balance to reach zero.

An overdraft may be considered for a short and temporary gap when the account holder knows how it will be cleared. It is less suitable as permanent extra income.

The bank may review the facility and its terms. Do not assume an overdraft limit will always remain available.

Example without a rate
Account balance-£500
Wages paid in+£1,200
New balance£700

If an account is £500 overdrawn and £1,200 in wages is paid in, the new balance becomes £700 before other transactions. The overdraft has been repaid, but normal spending could cause the account to become overdrawn again.

Repeatedly entering an overdraft soon after income arrives can be a sign that normal spending is relying on borrowed money.

How a credit card works

A credit card provides a reusable credit limit.

The card can be used to make purchases. Each statement shows the balance, the minimum payment, the due date and other important information.

Paying the full statement balance by the due date can avoid purchase interest on many standard cards, depending on the terms. If only part of the balance is paid, interest may be charged and the remaining debt moves into the next statement period.

Only making the minimum payment can keep the account up to date, but it may clear very little of the balance. Continued spending can prevent the debt from reducing at all.

The Financial Conduct Authority treats an account as being in persistent debt when, over an 18 month period, the customer has paid more in interest, fees and charges than they have repaid from the amount borrowed. Card providers must contact customers at defined stages and provide further support where required. The FCA’s credit card rules explain the process.

Credit cards and purchase protection

A credit card has one feature that a normal personal loan or overdraft does not provide.

Section 75 of the Consumer Credit Act may protect qualifying purchases costing more than £100 and up to £30,000. The credit card provider can share responsibility with the seller if goods are faulty, not supplied or misrepresented.

The rules are more detailed than the price range alone. The protection can depend on what was purchased, who bought it and how the payment was processed. MoneyHelper explains how you are protected when you pay by card.

Do not use a credit card solely to gain protection if the resulting balance would be unaffordable.

Cash withdrawals on a credit card

Using a credit card to withdraw cash can be expensive. A cash withdrawal may attract a fee and interest can start immediately rather than after the normal period for purchases.

Cash withdrawals can also be recorded differently from ordinary card spending and may be considered by future lenders.

If you need money in your bank account rather than a way to pay a retailer, check carefully whether a credit card cash withdrawal makes sense.

Why comparing APR alone is not enough

APR is useful, but these products do not all behave in the same way.

A loan has an agreed amount and term. An overdraft balance can change daily. A credit card balance changes as the card is used and repaid.

Compare the following:

  • The actual rate offered
  • Any fees that apply
  • How much will be borrowed
  • How long the balance is likely to remain
  • The required monthly payment
  • The planned monthly payment
  • The total expected cost in pounds
  • Whether the rate is fixed or variable
  • What happens if a payment is late
  • Whether the borrowing has a clear end date

Do not compare a loan’s representative APR with an assumed overdraft or card rate. Use the personal figures supplied by each provider.

The repayment structure matters

The major difference between these products is not access to money. It is what happens after the money is used.

A loan creates a schedule

The borrower follows a series of payments intended to clear the debt by a particular date.

An overdraft follows the bank balance

Money entering the account reduces the overdraft, but spending can take the account below zero again.

A credit card follows the borrower’s payments

The borrower must make at least the minimum payment, but can normally pay more. Paying more usually clears the balance sooner and reduces interest.

This is why two products with similar rates can produce very different total costs.

Compare the borrowing shape

Choose the situation closest to yours to see how the shape of each product fits it.

Illustrative example

Representative example: Borrowing £1,000 over 18 months with an annual interest rate of 59.97% fixed, you would make 18 monthly repayments of £89.22. The total amount repayable would be £1,605.96. The total interest charged would be £605.96. Representative 79.5% APR variable.

  • Cash withdrawals can involve immediate interest and fees

What if you have bad credit?

Poor credit does not automatically decide which product is suitable. It can, however, affect which products are available, the rate offered and the credit limit. Lenders also look at more than your credit score.

A person with poor credit may receive:

  • A smaller loan
  • A higher loan rate
  • A lower overdraft limit
  • A credit card with a low limit and high APR
  • No offer at all

Check eligibility before making a full application where a genuine soft search is available. Confirm that the check will not leave a visible hard search before submitting it. Our guide to soft and hard searches explains the difference.

Do not make several applications simply to see which one is accepted.

When none of the three is suitable

A loan, overdraft or credit card may all be unsuitable if you:

  • Cannot cover essential living costs
  • Are already missing repayments
  • Need new credit to make existing credit payments
  • Have no realistic plan to repay
  • Are depending on an uncertain future payment
  • Would be left with no room for unexpected costs

In this position, comparing credit products does not solve the underlying shortfall. MoneyHelper’s bill prioritiser shows which commitments to deal with first, and its free Debt Advice Locator can put you in touch with an adviser. Its overview of options for borrowing money covers alternatives beyond these three products.
