About This Tool
Why use Loan Calculator?
UK personal loans are usually fixed-rate and repaid in equal monthly instalments. Lenders advertise a representative APR, and the rules only require that at least 51% of successful applicants receive that rate, so your personal offer may be higher.
Before borrowing, check your credit report with the main credit reference agencies and use soft-search eligibility checkers so you do not leave multiple hard searches on your file. Car finance is often arranged as hire purchase (HP) or personal contract purchase (PCP), which work differently from a straightforward personal loan.
Key Benefits
Fixed monthly instalments
Matches how most UK personal loans are structured, with the same payment every month.
Overpayment savings
See how overpaying reduces interest. UK lenders can charge an early settlement fee, often up to one or two months' interest.
Affordability check
Compare the repayment with your take-home pay before applying, as lenders will assess affordability too.

Loan Calculator FAQs
What does representative APR mean?
It is the rate a lender expects at least 51% of successful applicants to receive. The rest may be offered a higher rate depending on their credit history and circumstances, so always check your personal APR.
Can I repay a UK personal loan early?
Yes. You have a legal right to settle a regulated loan early. The lender may charge a limited early settlement fee, but you will usually still save interest overall.
How much can I borrow with a personal loan?
Lenders look at your income, existing commitments and credit history. Keeping total monthly debt repayments comfortably within your take-home pay improves your chances of approval.
Which currency does this loan calculator use?
Amounts are shown in British Pounds (GBP). The formulas are the same everywhere, so you can switch to another country version if you need a different currency.
