What APR includes and what it does not
APR stands for annual percentage rate. It is a standardised way to show the yearly cost of credit as a percentage, so you can compare loans more easily. Under the Consumer Credit Act 1974 and FCA rules in CONC, lenders must present APR in certain credit advertisements and pre-contract information. It usually includes the interest rate and most compulsory fees, such as arrangement fees. It generally does not include optional products, charges that apply only if you break the agreement, or costs you can avoid.
APR is not the same as the interest rate. The interest rate tells you how much interest is applied to the amount you borrow, while APR adds most compulsory fees into one annual figure. APR is also not the same as the monthly payment. The total amount you repay depends on the amount borrowed, the term, the repayment schedule, and when payments are made.
Representative APR and your personal APR
A representative APR is the rate a lender must show in many regulated credit advertisements. It must be representative of the deals the lender expects to offer. Under FCA rules, it must be available to enough successful applicants for the claim to be fair. You can read more about how representative APR works in our guide to representative APR.
The APR you are actually offered is your personal APR. It is based on the lender's assessment of your circumstances, including your credit history, income, existing debts, and the amount and term you request. A lender may offer you a higher APR than the representative APR, or decline the application. The FCA expects firms to act fairly and to provide clear information.
APR, interest rate, and total cost compared
APR is useful, but it is not the only number that matters. The table below shows how the main figures differ.
| Measure | What it shows | What it leaves out |
|---|---|---|
| Interest rate | The annual cost of borrowing the balance, before compulsory fees. | Arrangement fees and other compulsory costs. |
| APR | The annual cost of credit including interest and most compulsory fees. | Optional products, some default charges, and your actual repayment behaviour. |
| Monthly payment | The amount due each month under the repayment schedule. | The total cost over the life of the loan. |
| Total amount repayable | The full amount you are scheduled to repay if you keep to the agreement. | Costs that arise if you change the agreement or miss payments. |
When you compare loans, use APR as a starting point, then check the total amount repayable and the monthly payment. The loan comparison guide explains how to weigh these factors together. Our loan comparison calculator can help you test different terms and repayments without treating APR as the only measure.
How APR is calculated in principle
APR is calculated using a standard method set out in consumer credit rules. It takes the amount you receive, the payments you make, their timing, and compulsory fees, then finds the annual rate that balances their present values. APR is therefore a time-value-of-money measure, not a simple fee total.
The calculation usually assumes you keep the loan for the full term, pay on time, and do not repay early. It may also assume a variable rate stays at its initial level. APR is therefore a comparison tool, not a forecast. The FCA CONC rules and the Consumer Credit Act 1974 set the framework.
The broad steps are:
- Identify the credit amount, the term, the repayment schedule, and all compulsory charges.
- List the cash flows: money advanced to you and each repayment you make.
- Find the annual percentage rate that balances the present value of those cash flows.
- Apply the required rounding and disclosure rules when the figure is shown to you.
Why APR can be misleading
APR is a strong comparison tool when you compare similar products over similar terms. It can mislead when products are very different. A short-term loan may have a high APR because the cost is annualised, even though the loan lasts only a short time. A longer loan may have a lower APR but a higher total amount repayable because you pay interest for longer. That is why APR should not be read on its own.
APR also assumes that you repay on time and keep the agreement for its full term. It does not capture missed payments, late payments, or early settlement. If you repay early, the lender may recalculate interest and apply a rebate under early settlement rules. Our guide to early repayment explains the principles. For flexible credit such as overdrafts or credit cards, APR may be less useful because your balance and repayment pattern can change.
If a lender or broker gives you misleading information about APR or the cost of credit, you can complain. The Financial Ombudsman Service can review complaints about regulated financial businesses through its complaint process. You can also see our complaints guide.
Your legal and regulatory protections
The Consumer Credit Act 1974 gives borrowers certain rights and protections. It covers the form of credit agreements, statements, and early settlement. For fixed-sum credit, section 77 lets you ask the lender for a copy of the agreement and a statement of account. The early settlement regulations set out how rebates can work when you repay early.
FCA rules add further requirements. Firms must be authorised where required, and they must follow rules on financial promotions, pre-contract information, affordability, and fair treatment. The CONC 5A rules deal with the calculation and use of APR in credit advertisements. The Consumer Credit Act also contains an unfair relationship test in section 140A, which allows a court to consider whether the relationship between lender and borrower is unfair.
Before you sign, check the agreement and pre-contract information. If something is unclear, ask the lender to explain it. You can also check whether a firm is authorised using the FCA register. If a dispute cannot be resolved, the Financial Ombudsman Service may be able to help. Our FCA regulation and your rights guide explains the wider framework.
How to use APR when comparing loans
Start by comparing the APR for loans of the same type and similar term. Then look at the total amount repayable, the monthly payment, and whether the rate is fixed or variable. Check whether the APR is representative and whether you are likely to qualify for it. A lender must not present a representative APR as if every applicant will receive it. The FCA rules on APR are relevant here.
Read the early repayment terms before you borrow. Some loans allow overpayments or early settlement with an interest rebate, while others may have different conditions. Our early repayment guide and overpayment calculator can help you understand the effect of paying more than required. Also check how the lender assesses affordability and what happens if your circumstances change. Affordability checks are part of the regulated lending process.
Finally, protect yourself. Check your credit file before applying, because multiple applications can affect your score. See our guide to checking your credit file. Be alert to scams and never pay an upfront fee for a loan that is not clearly explained. The loan scam guide offers practical checks.
