APR calculator (UK)
See the true annual cost of a loan once fees are included, and how far the APR sits above the interest rate.
APR calculator
Only the fees you enter are included — a fee left out cannot show up in the answer. In the United Kingdom, an advertised rate is often "representative", meaning most successful applicants are offered it rather than everyone.
Estimate only. This result is produced from the figures you entered and the assumptions listed on this page. It is not financial advice, not a quotation and not an offer, and no provider is bound by it. Check current terms with the provider before acting.

How this is worked out
The rate at which the present value of every repayment equals the money actually received.What this assumes
A calculator is only as good as what it leaves out. These are the assumptions built into the result above.
- Repayments are equal and made on schedule.
- Only the fees you enter are included. A fee left out cannot show up in the answer.
- The rate is fixed for the term.
- A lender’s advertised APR is often "representative", meaning most applicants are offered it — not everyone.
