The cost of a loan depends on:
Your credit score – this shows how well you’ve managed borrowing in the past. Lenders use it to help decide whether to offer you credit and what APR to charge
Your income – how much you earn
The loan amount – it’s generally best to borrow only what you need. The more you borrow, the more interest you’ll pay overall
The loan term (length of time you repay it over) – the longer the term, the more interest you’ll pay in total, although your monthly repayments may be lower
Affordability – whether the repayments look manageable alongside other costs.

How the loan term affects your repayments
Repaying over a longer term means smaller monthly payments but more interest overall.
Here’s how a £5,000 fixed-rate personal loan compares when repaid over 2, 3 or 4 years, assuming no extra fees (based on Compare the Market's representative 10.3% APR^).
Loan term | Monthly repayment | Total interest | Total amount repayable |
|---|
2 years | £230.36 | £528.73 | £5,528.73 |
3 years | £160.97 | £794.88 | £5,794.88 |
4 years | £126.44 | £1,069.00 | £6,069.00 |
Illustrative example: Priya’s bathroom loan
Priya needs £5,000 for a new bathroom. She has savings but wants to keep an emergency buffer, so she’s considering a personal loan. She has a job and a fair-to-good credit score, and can afford to set aside around £200 a month.
Monthly repayments on a two-year loan would cost more than her £200 budget. Borrowing over four years would give her the cheapest monthly payments but cost about £540 more in interest than a two-year loan (£6,069 vs £5,529).
She picks a three-year term as a compromise: manageable repayments at £161 per month (10.3% rep APR^, assuming she qualifies) and around £795 in total interest.
^Representative example: Borrowing £7,500 over 48 months on a personal loan at a fixed interest rate of 10.3% p.a. results in monthly payments of £191.30 and a total repayable of £9,182.48. Representative 10.3% APR (fixed). Correct as of September 2026.
What our expert says...
“Before applying for a loan, take a few minutes to make sure it’s right for your budget. Check what the repayments will be each month, how much you’ll pay back overall and whether you could still afford the loan if your circumstances changed. It’s also worth checking your credit report for any mistakes.
“A little preparation can improve your chances of being accepted and help you borrow with confidence.”
