Borrowing costs more than most people realise — and less than it needs to, if you match the right product to the right use case. The difference between choosing a 7% APR personal loan and a 35% APR credit card for the same £5,000 could be over £1,500 in additional interest over a 3-year term. Getting the comparison right before you apply is worth the time.
This hub covers personal loans, credit card borrowing, guarantor routes, payday alternatives, and how APR works in practice. For managing existing unaffordable debt, see the Debt Solutions hub.
Borrowing Options Compared — 2026
| Borrowing type | Typical APR | Amount | Best use case |
|---|---|---|---|
| Personal loan (best rate) | 3–7% APR | £7,500–£25,000 | Planned large purchase, home improvement, car |
| Personal loan (standard) | 7–15% APR | £1,000–£7,500 | Smaller planned purchases |
| 0% purchase credit card | 0% for 12–24 months | Up to limit | Short-term planned spend cleared within promo period |
| Credit union loan | 3–42.6% APR (capped) | £50–£15,000 | Community lending, lower rates for members |
| Authorised overdraft | ~39.9% EAR | Up to limit | Short-term emergencies only |
| Guarantor loan | 30–50% APR | £500–£10,000 | Poor credit, last resort |
| High-cost short-term credit | 100%+ APR equivalent | Small amounts | Avoid — almost always cheaper alternatives exist |
Worked Example — Personal Loan vs Credit Card for £5,000
Scenario: Alex needs to borrow £5,000 for a home improvement project. He has two options.
| Option | APR | Monthly payment | Term | Total repayable | Total interest cost |
|---|---|---|---|---|---|
| Personal loan (7%) | 7% | ~£154 | 36 months | ~£5,556 | £556 |
| Standard credit card (24.9%) | 24.9% | ~£180 | 36 months | ~£6,480 | £1,480 |
| 0% purchase card (clears in 18 months) | 0% | £278 | 18 months | £5,000 | £0 |
The 0% purchase card is cheapest — but only if Alex can sustain the £278/month payment and clear the balance before the promotional rate expires. The personal loan is cheaper than the credit card and offers predictable fixed payments. The standard credit card is the worst of the three options if Alex cannot clear the balance quickly.
How APR Works — Practical Breakdown
APR (Annual Percentage Rate) allows you to compare borrowing costs across different products and terms. Key points:
- Representative APR means at least 51% of approved applicants receive that rate — up to 49% may be offered higher
- EAR (Equivalent Annual Rate) is used for overdrafts and current accounts
- Total repayable is the most honest single number — always check this, not just the monthly payment
| Loan amount | APR | Term | Monthly payment | Total repayable |
|---|---|---|---|---|
| £5,000 | 7% | 3 years | ~£154 | ~£5,556 |
| £5,000 | 15% | 3 years | ~£173 | ~£6,228 |
| £10,000 | 6% | 5 years | ~£193 | ~£11,580 |
| £10,000 | 12% | 5 years | ~£222 | ~£13,320 |
Best rates (3–6% APR) typically apply to loans of £7,500–£25,000 with a clean credit history. Smaller loans tend to have higher rates proportionally.
Personal Loan vs Credit Card — When to Use Each
| Scenario | Better option | Reason |
|---|---|---|
| £500–£2,000, can repay in 12 months | 0% purchase credit card | Free financing if cleared before promo end; Section 75 protection |
| £2,000–£5,000, 2–3 years | Personal loan or 0% card | Depends on rates available |
| £5,000+, 3–5 years | Personal loan | Loan APR typically lower; fixed monthly payments |
| Purchase between £100–£30,000 | Credit card (part payment) | Section 75 protection applies |
| Flexibility needed | Credit card | Minimum payment option; loan has fixed commitment |
Choosing a Personal Loan — Eligibility and Credit File
Your credit score significantly affects the rate offered. Key eligibility factors lenders consider:
| Factor | Effect |
|---|---|
| Credit score (good–excellent) | Access to best 3–7% rates |
| Credit score (fair) | Likely 10–20% APR range |
| Credit score (poor) | May be declined or offered 25%+ APR |
| Electoral roll registration | Improves verification and approval odds |
| Existing debt-to-income ratio | High existing commitments can trigger rejection |
| Multiple recent applications | Hard searches reduce approval odds |
Use soft-search eligibility tools before applying. Each full loan application creates a hard search on your credit file, visible to lenders for 12 months. A cluster of hard searches in a short period signals financial difficulty to future lenders.
Safer Borrowing Routes — Credit Unions and DWP Loans
Before using high-cost credit, always check lower-cost alternatives:
| Alternative | Who it suits | Key benefit |
|---|---|---|
| Credit union loan | Members of a local or employer credit union | APR capped at 42.6% by law; typically far lower for members |
| DWP Budgeting Loan | People receiving qualifying benefits | Interest-free — repaid through benefit deductions |
| Local welfare assistance | Those in crisis with low income | Council grants/loans for essential items |
| Employer salary advance | Employed workers | 0% or very low cost, deducted from next payslip |
| 0% balance transfer | Existing credit card debt | Freeze interest while you repay |
High-Cost Credit — Recognising the Danger Signs
High-cost short-term credit (formerly called payday loans) can appear affordable by quoting a weekly cost rather than APR. Always convert to APR for comparison.
Signs of a high-cost product to avoid:
- Advertised rate is a daily, weekly, or monthly percentage — not annual APR
- No credit check required
- Approval in under 10 minutes
- Very short repayment terms (30–90 days) for significant amounts
- Rollover or extension options built in
The FCA has capped the total cost of high-cost short-term credit at 100% of the original borrowed amount — but this still represents extremely expensive borrowing compared to alternatives.
