Both a balance transfer card and a personal loan can consolidate existing debt into one place. Which one costs less depends on how much you owe, how quickly you can repay, and the rates you are offered.
This article is information, not financial advice. It sets out how both options work and what to weigh up. Your own circumstances will differ, so you may want to speak to a free debt adviser or use the tools below before deciding.
What is the difference between the two options?
A balance transfer card lets you move existing credit card balances onto a new card, often at 0% interest for a set promotional period. You pay a one-off transfer fee when you move the balance, then repay the outstanding amount before the promotional period ends. After that, the rate reverts to the card's standard rate.
A personal loan gives you a fixed sum upfront, which you use to pay off existing debts. You repay the loan over a set term at a fixed (or occasionally variable) interest rate, with the same monthly payment each time.
The core difference is structure. A balance transfer card can be cheap if you clear the balance within the 0% window. A personal loan costs interest from day one, but gives you a predictable repayment schedule.
How do the two options compare side by side?
| Feature | Balance transfer card | Personal loan |
|---|---|---|
| Interest cost | 0% during promotional period; reverts to standard rate after | Interest charged throughout the term; rate fixed at the point of offer |
| Upfront fee | Transfer fee, typically 1% to 3% of the amount moved | None in most cases; some lenders charge an arrangement fee |
| Repayment flexibility | Minimum monthly payment required; can overpay freely | Fixed monthly instalment; some lenders charge an early repayment fee |
| Repayment period | Promotional periods commonly range from 12 to 30 months | Terms typically 1 to 7 years |
| Typical APR after promo | Can be high once promotional period ends | Representative APR varies by lender and applicant |
| Borrowing limits | Generally lower credit limits | Loans can reach £25,000 or more depending on lender and creditworthiness |
| Best for | Clearing card debt fast within the 0% window | Structured repayment of larger or mixed debts over a longer period |
| Credit score impact | Hard search on application; new credit utilisation on file | Hard search on application; closed accounts and new loan on file |
Which suits whom?
Balance transfer card may be worth considering if:
- Your existing debt is mostly on credit cards.
- The total balance is manageable within a 12 to 30 month payoff plan.
- You have a strong enough credit history to qualify for a long 0% period.
- You can commit to paying more than the minimum each month.
- You want to avoid paying interest, and can clear the balance before the promotional rate expires.
Personal loan may be worth considering if:
- Your existing debt includes loans, overdrafts or other non-card balances.
- The total balance is large and needs more than two years to repay.
- You prefer a fixed monthly payment so you always know where you stand.
- You are at risk of reverting to spending on a card if it remains open and available.
- The loan rate is competitive compared with the transfer fee plus revert rate risk.
What are the key costs to check?
For a balance transfer card:
- The transfer fee. Most cards charge 1% to 3% of the amount transferred. On a £5,000 balance, that is £50 to £150 upfront.
- The revert rate. This is the APR that applies once the promotional period ends. If you have not cleared the balance, you start paying interest at this rate.
- The minimum monthly payment. Paying only the minimum is unlikely to clear the balance in time. It can help to divide the total balance by the number of months in the 0% period and use that as your monthly target.
For a personal loan:
- The APR. The advertised figure is the representative APR, which at least 51% of accepted applicants receive. You may be offered a different rate. Comparing the total amount repayable across lenders, not just the headline rate, gives a more accurate picture of cost.
- The term. A longer term reduces monthly payments but increases total interest paid.
- Early repayment charges. Some lenders charge a fee if you pay off the loan early. It is worth checking this before committing, particularly if your circumstances might change.
What to check before you apply
Before applying for either product, a few checks can reduce the risk of a declined application affecting your credit file.
Use an eligibility checker. Both card providers and loan lenders typically offer soft-search eligibility checkers. These show your likelihood of acceptance without leaving a mark on your credit file. A hard search, which is triggered by a full application, can cause a small, temporary dip in your credit score.
Check your credit report. Your credit file shows what lenders see. Errors on the file can affect the rate you are offered. Checking it with one of the three main credit reference agencies (Experian, Equifax or TransUnion) before applying is a useful first step.
Work out your total monthly outgoings. Lenders carry out an affordability check before approving any credit. This looks at income, existing commitments and the new repayment. The affordability checklist can help you map this out before applying.
Run the numbers. The loan repayment calculator can show what a personal loan would cost at different rates and terms. For a balance transfer, divide your balance by the number of months in the 0% period to check whether the monthly payment is achievable.
What can go wrong?
Even at low risk, both options carry pitfalls worth knowing.
Balance transfer card risks:
- Missing the end of the promotional period. Reverting to the standard rate unexpectedly can make the remaining balance more expensive than the original debt.
- Spending on the card. If the card remains open and you use it for purchases, you may build new debt alongside the balance you are trying to clear.
- Transfer not completing. Balance transfer requests can be declined or partially approved. If that happens, you may need to contact the new card provider before assuming the transfer is done.
Personal loan risks:
- Being offered a higher rate than advertised. The representative APR is not the rate you will necessarily receive. If the actual rate is significantly higher, the loan may cost more than expected.
- Early repayment charges. Paying off the loan early to save interest may trigger a fee that offsets some of the saving.
- Extending the debt period. A lower monthly payment may look appealing, but a longer term means more total interest paid.

Frequently asked questions
Can I transfer a personal loan balance onto a balance transfer card?
Most balance transfer cards only accept existing credit card balances, not personal loan balances. Some cards do accept loan balances as a 'money transfer', but this is a different product with different fees. Check the card's terms carefully before applying.
Will applying for either option hurt my credit score?
A full application for either product involves a hard search on your credit file, which may cause a small, temporary dip in your credit score. Using an eligibility checker first uses a soft search and does not affect your score. It is worth checking eligibility before applying formally.
What happens to a balance transfer card when the 0% period ends?
The interest rate reverts to the card's standard purchase or balance transfer rate, which can be considerably higher. If you have not cleared the balance by then, remaining debt starts accruing interest at the revert rate. Setting a monthly payment plan to clear the balance before the promotional period ends is a useful precaution.
Is a personal loan better if I need to borrow more money on top of consolidating?
A personal loan can cover both consolidation and additional borrowing in one amount, with a fixed repayment plan. A balance transfer card is designed for moving existing balances rather than providing new funds, though some cards offer a separate purchase rate for new spending.
Does the representative APR apply to me?
No. The representative APR is the rate that at least 51% of accepted applicants receive. You may be offered a higher rate depending on your credit history and circumstances. Checking your rate before accepting is important, as the actual cost could differ from the advertised figure.
Can I use both a balance transfer card and a personal loan together?
It is possible, but taking on multiple new credit products at once affects your credit file and monthly outgoings. Lenders will assess affordability based on all existing commitments. A useful first step is to check whether one option alone can cover what you need before considering both.
