Annual Percentage Rate (APR)

A standard measure of the cost of credit

APR stands for annual percentage rate. It is a standardised way of expressing the total cost of borrowing as a yearly percentage, so that different credit products can be compared on a like-for-like basis. Crucially, the APR is not the same as the interest rate alone. It brings together the interest charged and any compulsory fees associated with the credit, and expresses them as a single annualised figure calculated according to a prescribed method. Because the calculation also reflects when payments fall due over the life of the agreement, the APR captures the real cost of the money over a year rather than a headline interest figure.

The purpose of this standardisation is to protect consumers from being misled by a low advertised interest rate that hides fees, or by quoting practices that make one deal look cheaper than another when it is not. By folding the compulsory costs into one comparable number, the APR lets a borrower judge the true relative cost of competing offers.

Representative APR versus personal APR

Where a lender advertises credit, it usually quotes a representative APR. This is the rate that a defined proportion of successful applicants are expected to receive, and it is the figure that appears in a representative example alongside other required information. It gives prospective customers a realistic sense of the typical cost, while acknowledging that not everyone will be offered exactly that rate.

The rate an individual is actually offered is the personal APR, and it may be higher or lower than the representative figure. Many UK lenders use risk-based pricing, where the price reflects the assessed risk of the particular applicant, so a strong credit profile may attract a lower personal APR and a weaker one a higher rate. This is why a customer can apply for an advertised product and be offered a different rate: the representative APR describes the typical outcome across many applicants, whereas the personal APR is specific to them.

As an illustrative example only, an advertising a loan might show a representative APR used in the required example, while individual applicants receive personal rates set by their own assessment. The specific figures in any real example depend on the lender and should not be inferred from illustration.

APR in UK credit advertising and decisioning

Displaying APR is not optional in UK consumer credit. The rules require that credit advertising which quotes a rate or an incentive includes a representative APR and a representative example containing prescribed information, so that the headline cannot be presented without the full comparable cost. These requirements sit within the broader framework of the Consumer Credit Act and the FCA's rules in CONC, and are reinforced by the Consumer Duty's expectations around clear communications, fair value and helping customers understand what they are buying.

For a lender, APR connects pricing, decisioning and compliance. Risk-based pricing sets the personal APR an applicant is offered, affordability assessment ensures the resulting repayments are sustainable, and the advertising rules govern how the product is presented in the first place. Getting these to work together, pricing fairly, lending responsibly and communicating the cost clearly, is central both to treating customers well and to meeting the regulator's expectations. A clearly presented APR is one of the simplest signals a lender can give that it is competing on genuine cost rather than on how the price is dressed up.
