When you start comparing car finance deals, APR is the number that appears everywhere. But if you have ever applied for finance and received a rate that looks nothing like the figure advertised, you are not alone and there is a straightforward explanation for why that happens.
What is APR in car finance?
APR stands for Annual Percentage Rate. It represents the true annual cost of borrowing, expressed as a percentage, and includes both the interest rate and any associated fees. It exists specifically to allow you to compare finance deals on a like-for-like basis, regardless of the lender or the product type. In short, the higher the APR, the more the finance will cost you over its full term.
What does representative APR actually mean?
Here is where a lot of car buyers get understandably confused. When a lender or broker advertises a representative APR, they are not promising that rate to everyone. Under FCA regulation, the representative APR is simply the rate that must be offered to at least 51% of accepted applicants. That means up to 49% of people who are approved may receive a higher rate than the one advertised.
This is not a bait and switch — it is a legal advertising standard. The representative rate gives you a useful reference point for comparison, but it is not a guarantee of what you personally will be offered.
