About Personal Loan Calculator (UK)
Unsecured credit is priced on you, not on collateral — which is why the UK personal-loan quotes span such a wide band. The defaults here (£7,500 at 6.7% over 4 years) sit mid-market; type in the exact offer you've been given to see the instalment, the total interest and how fast the balance actually falls. UK loan pricing has a famous shape: rates drop sharply at £7,500–£15,000 (the default £7,500 at 6.7% reflects that sweet spot) and rise for smaller amounts — borrowing £4,000 can cost a higher APR than £7,500. Remember 'representative APR' only has to be offered to 51% of accepted applicants; your personalized quote after a soft-search eligibility check is the number that matters. The Consumer Credit Act gives you strong exit rights: you can settle early at any time, with the lender allowed to charge at most ~1–2 months' interest as compensation (s.95 rebate rules), and you have a 14-day right of withdrawal after signing. Soft-search eligibility checkers across multiple lenders won't dent your credit file — use them before any hard application.

Frequently asked questions
What is the monthly instalment on a £7,500 personal loan?+
At 6.7% for 4 years the reducing-balance formula gives the figure shown above. Because personal loans are short, small rate differences matter less than fees — a 2% upfront processing/origination fee on £7,500 often outweighs a 0.5% rate discount. Compare total cost, not the rate alone.
Why was I offered a higher rate than the advertised APR?+
Only 51% of accepted borrowers must receive the representative APR; the rest are priced on their credit file, income and loan size. If your quote is well above representative, try a different lender's soft-search tool — pricing models differ surprisingly, and your existing bank often (not always) prices loyalists better.
Is it cheaper to borrow a bit more in the UK?+
Sometimes genuinely yes — £7,500 at the sweet-spot APR can cost less in total interest than £6,500 at a small-loan APR. Run both scenarios in this calculator and compare total repayment. Only do it if the surplus has a purpose; cheap debt is still debt.
Will prepaying a personal loan save me much?+
Yes, but mostly in the first half of the term — that's when the interest share of each instalment is largest. Check your lender's prepayment clause first: rules differ by market and by fixed vs floating pricing, and a stiff prepayment fee can eat a year's worth of interest savings.
