How useful are Annual Percentage Rates for consumers?

APR isn’t perfect, but still a useful figure, feels like the honest take. It gives people a quick way to compare deals, even if most don’t fully understand how it’s worked out. It’s better than having no benchmark at all, but it can still feel a bit unclear, and the real cost doesn’t always match what people expect. Good as a starting point, just not something to rely on blindly.

Interest and costs should be clear, readily understandable, easily comparable and standardised across advisers so clients can shop around without being bamboozled.

I believe the "True Cost" of the mortgage during the fixed rate period (where relevant), as well as the actual interest cost (in pounds and pence), and balance at the end of the fixed rate period are far more valuable to the client in making the right decision. APRC factors in the current lender SVR (Standard Variable Rate) for the remaining term after the fixed period, which is not only impossible to predict but with the modern mortgage culture helping clients re-mortgage or rate switch after their fixed rate may be more misleading than of any use. Especially for comparison purposes where lenders SVRs can differ wildly.

The illustration document itself (often called an ESIS) should also come with a simplified A4 (at most) cover with the key figures up front, rather than just burying them in 9 pages of jargon.

APRs are useful in theory, but in practice they often give customers a false sense of clarity. The intention is right: one headline figure to help people compare borrowing costs. The issue is that borrowing is rarely that simple. Many customers see APR and assume it tells them exactly what they will pay, when the real cost depends on the loan size, term, fees, product structure, repayment behaviour and whether the rate is fixed, variable or promotional. In mortgages especially, the lowest APR is not always the best outcome. A product with a slightly higher rate but lower fees, more flexibility or better suitability may be more appropriate. I do not believe most customers fully understand APRs; not because they lack intelligence, but because the figure is technical, not human-friendly. APRs can support good outcomes, but only alongside clear explanations of total cost, monthly payments, fees, risks and what happens if circumstances change. A number on a page does not replace advice now.

APR is the wrong figure to compare fixed rate mortgages on, and the consumer confusion the research is picking up is entirely rational. The APR calculation assumes a borrower stays on the lender’s reversion rate for the rest of the term. We contact every client ahead of their fixed rate expiring to review options and switch them onto a new deal, so for the vast majority of borrowers that reversion rate never applies. The headline figure is built on a scenario that will not happen. Clients should still read APR, it is a regulated disclosure for good reason, but the number that actually matters is total cost over the fixed period: rate, product fee, valuation, broker fee, and interest paid. That tells a client what the deal will cost them in pounds across the period they will hold it. APR, for the way the UK fixed rate market is used, answers a question almost no borrower is asking.

APRs are useful in theory as a standard benchmark for comparing total borrowing costs, which can assist in comparing rates across lenders.

In practice their usefulness is limited as many consumers misunderstand what they include, and may focus on the headline rates as opposed to the real underlying borrowing costs.

They tend to be more useful for long-term borrowing as for short term loans they can be misleading as they annualise the costs that are only applicable over the short term.

APRs are inherently flawed, but they are often too complex to be fully effective in giving consumers real insight to borrowing costs. Better education about APRs alongside wider financial education would be helpful for many.
