Head to head
| Factor | Short-term personal loan | Credit card |
|---|---|---|
| Interest rate | 39.9–149.9% APR (indicative) | 20–30% (standard); 0% intro deals available |
| Interest structure | Fixed — calculated at start | Variable; compounds if not cleared monthly |
| Monthly payment | Fixed — same every month | Minimum only (dangerous); you choose amount |
| Speed to cash | Same day if approved | 3–5 days for new card; instant if existing |
| Approval requirement | Affordability + credit check | Credit check; good score needed for 0% deals |
| Flexibility | Fixed term, fixed amount | Revolving — can reuse as you repay |
| Overpayment | Yes, early settlement any time | Yes, pay any amount any time |
| Missing a payment | Late fee + credit mark | Late fee + loses 0% deal + credit mark |
| Best case scenario | Know exact cost from day one | 0% for 18+ months = zero interest cost |
| Worst case scenario | Fixed rate, predictable | 30%+ APR compounding on a growing balance |
The key question: will you clear it in time?
The entire case for a 0% credit card rests on one assumption: you clear the balance before the 0% period ends. If you do, you've borrowed for free. If you don't, the revert rate (typically 22–30% APR) applies to the full remaining balance from that point.
A personal loan has no cliff edge. You know from day one exactly what you'll pay, when you'll finish, and there are no penalty rates. For people who aren't confident they'll clear a card in time, the "more expensive" loan is often cheaper in practice.
Rule of thumb: If you have a 0% card offer, can qualify for it, and are highly confident you'll clear it — take the card. If any of those three conditions is uncertain, a loan with a fixed rate and fixed end date is the safer bet.
When a short-term loan wins
You need cash, not a purchase card
Personal loans pay cash into your account. Most credit cards can't be used for cash without a cash advance fee (3–5%) and immediate interest from day one — even on 0% cards.
You want certainty
A loan's total cost is fixed before you sign. You know the exact end date and total repayable. Cards are variable and rely on discipline.
Your credit score won't get you the best card deal
0% deals typically require a good to excellent credit score. A short-term personal loan lender may approve you where a 0% card wouldn't.
The amount is under £500
Most credit cards have minimum spend requirements for 0% offers. For smaller amounts, a short-term loan is often the cleaner option.
When a credit card wins
You qualify for a 0% offer and will clear it
If you can get a 0% purchase card and the discipline to pay it off before the deal ends, you borrow for free. Nothing beats that on pure cost.
You're buying from a retailer (Section 75)
Credit card purchases between £100–£30,000 get Section 75 protection — if the retailer fails or the goods don't arrive, your card issuer shares liability.
You need flexibility
Revolving credit means you can repay and redraw as your situation changes. A loan is a one-shot amount; a card lets you use what you need.
Your purchase is spread over time
If you're paying a builder in stages over several months, a card lets you manage the spend incrementally.
A worked example
You need £800 and will repay over 12 months.
Personal loan
£800 at 49.9% APR, 12 months
~£76/month
Total repayable: ~£910
Interest: ~£110 — fixed. No surprises.
0% credit card (cleared in time)
£800 at 0%, paid over 12 months
~£67/month
Total repayable: £800
Interest: £0 — if cleared. If not: ~25% APR kicks in.

FAQ
A short-term personal loan gives you a fixed lump sum upfront, with fixed monthly repayments over a defined term — you know exactly when the debt ends. A credit card gives you a revolving limit you can use repeatedly, with variable minimum payments and no fixed end date unless you choose to pay it off.
It depends on how you use them. Credit cards often have lower rates for borrowing held over years, but if you only pay the minimum each month, the total cost can be very high. A short-term loan has a fixed cost you can calculate before you borrow — Cash Train loans, for example, have a fixed daily interest rate and a 100% total cost cap.
Yes. Some people use a personal loan to consolidate credit card debt into a single monthly payment at a fixed rate. Before doing this, check that the total cost of the loan (interest + fees) is lower than the total remaining interest on the credit card balance.
Generally yes. For a specific, one-off purchase where you want certainty about the cost and a fixed repayment end date, a short-term personal loan is often more suitable than putting it on a credit card, where it is easy to carry the balance indefinitely while paying only the minimum.
