APR and total repayable: how to understand the real cost of borrowing

What APR means

APR stands for annual percentage rate of charge. Under the FCA’s consumer credit rules it is worked out as the yearly rate that balances the money you receive against everything you repay, including charges.

Because it brings interest and fees together, MoneyHelper suggests comparing APRs rather than interest rates alone. A loan with a lower interest rate but a large arrangement fee can cost more than one with a higher rate and no fee, and the APR shows that.

What APR includes and what it leaves out

The APR is built from the total charge for credit, which is the total cost of the credit to you. That includes interest and compulsory charges. A fee you pay to a credit broker counts too, when the lender knows about it.

Representative APR is not always your APR

Adverts often show a representative APR. Under the FCA’s rules, that is a rate the advertiser reasonably expects at least 51% of the agreements from the advert to be at or below.

That means up to 49% of people who are accepted could be offered a higher rate. MoneyHelper points out that you usually only find out your actual rate after you apply. Ask for your personal APR and total before you agree to anything.

The total amount repayable

The total amount repayable, sometimes called the total amount payable, is the clearest figure for most people. In the FCA’s rules it is the total charge for credit added to the amount you borrowed, plus any advance payment.

It answers the question most people actually have: how much will I hand over in total? It is fixed at the start for fixed-rate credit, and it appears in the information you must be given before you sign.

What a representative example must show

If an advert mentions an interest rate or any amount relating to the cost of credit, it must also include a representative example. Under the FCA’s rules the example has to show:

• the rate of interest, and whether it is fixed or variable
• any other charges included in the total charge for credit
• the total amount of credit
• the representative APR
• the duration of the agreement, the total amount payable and the amount of each repayment

Use the example to compare like with like. It is a worked illustration, not a quote for you.

Why short loans can show very high APRs

APR is calculated on an annual basis. On credit that lasts only weeks or months, turning the cost into a yearly rate can produce a very large percentage. That is why APR works best for comparing credit of a similar length, and why the total amount repayable matters so much for short-term borrowing.

Whatever the length, compare the total you will repay with what you can genuinely afford each week or month.

Cheaper ways to borrow

If you need to borrow, check the cheaper options first. In Great Britain, credit unions cannot charge more than 3% a month on the balance, including all their administrative costs. MoneyHelper gives that as 42.6% APR. If you are on certain benefits, there may also be government help, and a free debt adviser can talk you through the options.

Common questions

Is a lower APR always cheaper?

Not always. APR compares credit well when the amount and length are similar. For a different length of loan, look at the total amount repayable and the size of each payment too.

Does the APR include late payment fees?

No. Charges for missed or late payments are not part of the total cost of credit, so they are not included in the APR.

Why was I offered a higher rate than the advertised APR?

The advertised rate is a representative APR. Only at least 51% of agreements from the advert have to be at or below it, so some people are offered more. You usually find out your own rate after you apply.

Can I pay off a loan early to reduce the cost?

Yes. You can repay a regulated consumer credit agreement in full at any time by giving notice and paying what is due, less any rebate of charges.
