Every personal loan advert shows a representative APR. It is the number in large print. It is the number comparison sites sort by. And it is the number that up to 49% of accepted applicants do not receive. The representative APR is a legal requirement: the lender is expected to offer it to at least 51% of the borrowers who take out a loan as a result of the advert. The remaining 49% are offered a higher rate based on their individual credit profile, and the gap between the advertised rate and the rate actually offered can be several percentage points.
This tool shows what that gap costs. Enter the advertised representative APR, the loan amount, and the term, and the tool generates three scenarios: the advertised rate, an illustrative near-prime rate, and an illustrative higher rate. If you have a personal rate from a soft-search eligibility check, enter it in the fourth panel to see exactly where you sit. All non-representative rates are illustrative. This tool is for informational purposes and does not constitute financial advice.

The representative APR is offered to at least 51% of borrowers who take out a loan as a result of the advert. Up to 49% may be offered a higher rate. This tool shows what the gap costs.
The 51% rule is set by the Consumer Credit (Advertisements) Regulations 2010. It means a lender advertising 6.9% representative APR is expected to offer 6.9% or lower to at least 51% of the people who take out a loan through that advert. The other 49% may receive 8%, 12%, 18%, or higher, depending on their credit profile. The representative APR is the best case for the majority, not the rate everyone gets.
-
Three scenarios show the monthly payment and total cost at the representative rate, a near-prime rate (+4pp), and a higher rate (+12pp). The cost bars make the gap visual.
On a £10,000 loan over 3 years, the difference between 6.9% and 18.9% APR is approximately £1,850 in total interest. The borrower offered 18.9% is paying nearly £1,850 more than the headline rate suggested, for the same loan from the same lender. The three scenario cards make this gap impossible to miss.

Enter your personal rate from a soft-search eligibility check to see where you sit in the range. This turns the tool from illustrative to personalised.
A soft-search eligibility checker returns an indication of the rate likely to be offered. Entering that rate into the “your rate” panel shows the monthly payment, total cost, and how much more (or less) you would pay compared to the representative APR. If the personal rate is significantly above the representative, comparing other lenders through additional eligibility checks may reveal a better option.

About this tool
Useful for understanding what the headline rate actually means and what the loan might cost if the rate offered is higher than the representative APR.
The three scenarios (representative, near-prime, higher) show the range of outcomes from the same lender’s product. The “your rate” panel personalises the comparison.
No other tool on the market shows what the representative APR system costs the 49% of borrowers who do not receive the headline rate. This tool translates percentage points into pounds of additional interest.
The +4pp and +12pp scenarios are illustrative composites. The rate any individual is offered depends on their profile. Use soft-search eligibility checkers to see your actual personal rate.
How to use this tool
This is the rate shown in the lender’s advert or on the comparison site. Common representative APRs for mainstream personal loans range from 3% to 15%, with the most competitive products in the 5% to 8% range.
Enter the amount and term you are considering. The three scenarios and the “your rate” panel all use the same amount and term, making the comparison purely rate-driven.
The representative rate shows the best case (what 51% get). The near-prime rate shows a common outcome for borrowers just outside the top tier. The higher rate shows what borrowers with fair or lower profiles may face. The cost bars and difference labels make the gap tangible.
If you have run a soft-search eligibility check and received a personal rate indication, enter it in the navy panel. The tool shows the monthly payment, total cost, and how much more (or less) you would pay compared to the representative. This is the figure that matters for your decision.
What the gap between representative and personal rate costs
The representative APR is a marketing figure that shows the rate available to the strongest applicants. It is useful for comparing lenders against each other (a lender advertising 5.9% is broadly cheaper than one advertising 8.9% for the strongest borrowers), but it is not useful for predicting what any individual borrower will pay unless they are confident they fall in the top 51% of accepted applicants.
The cost of the gap between the representative rate and the personal rate grows with the amount and the term. On a £5,000 loan over two years, a four-percentage-point gap costs approximately £200 in additional interest. On a £15,000 loan over five years, the same four-percentage-point gap costs approximately £1,600. These are not trivial amounts, and they are invisible to borrowers who assume the representative APR is the rate they will receive.
The guide to understanding APR on personal loans covers the representative APR system in full, and the guide to what credit score you need covers how different score bands typically translate into different rate tiers.
Using your personal rate from an eligibility check
The “your rate” panel in the tool is designed for borrowers who have already run a soft-search eligibility check and received a personal rate indication. This rate is the lender’s estimate of what it would offer, based on the applicant’s actual credit file data. It is not guaranteed (the rate can change at formal application), but it is a far more accurate prediction than the representative APR.
Entering the personal rate into the tool shows exactly where the borrower sits in the range: at the representative rate (top tier), between the representative and near-prime (above average), or above the near-prime (where the additional cost becomes significant). If the personal rate is substantially above the representative, this is a signal to check rates with other lenders through additional eligibility checks, because a different lender’s scoring model may price the same borrower more favourably.
The guide to soft searches and eligibility checkers covers how to use these tools to compare personal rates across multiple lenders before submitting a formal application. The guide to how to find a low-rate personal loan covers the full comparison process.

What does “representative APR” actually mean?
The representative APR is the annual percentage rate that a lender is expected to offer to at least 51% of the borrowers who take out a loan as a result of a particular advert. It is a legal requirement set by the Consumer Credit (Advertisements) Regulations 2010, designed to ensure that the rate shown in adverts reflects the rate that a majority of successful borrowers receive. It is not a guarantee that any individual applicant will receive that rate.
The remaining 49% of accepted applicants may be offered a higher rate based on their individual credit profile, income, existing commitments, and the lender’s own scoring model. Some of the 49% may receive a rate only slightly above the representative. Others may receive a rate that is significantly higher. The tool’s three scenarios illustrate this range.
How do I know which tier I fall into?
The only reliable way to know is to run a soft-search eligibility check with the lender. This performs a soft credit check (invisible to other lenders) and returns an indication of the rate likely to be offered. If the indicated rate matches the representative APR, you are in the top tier. If it is higher, you are in the 49% who are offered a different rate, and the tool shows what that difference costs.
Without an eligibility check, the credit score provides a general guide. Borrowers with scores in the excellent range at all three agencies are most likely to receive the representative APR. Borrowers in the good range may receive it or a rate slightly above. Borrowers in the fair or poor range are more likely to be in the higher-rate tiers. The guide to what credit score you need covers the typical relationship between score bands and rate tiers.
Can I be declined even though the advert shows a rate?
Yes. The representative APR applies to accepted applicants only. A lender can decline any applicant who does not meet its credit, income, or affordability criteria, regardless of the rate advertised. The 51% rule means that of the borrowers who take out a loan as a result of the advert, at least 51% receive the representative rate or lower. It says nothing about the acceptance rate itself. A lender could decline 70% of applicants and offer the representative APR to 51% of the 30% it accepts.
This is why soft-search eligibility tools are valuable. They show not just the likely rate but also the likely acceptance decision, before a formal application triggers a hard search. A “likely to be declined” result from an eligibility checker is useful because it prevents a wasted hard search on the credit file.
Why are the illustrative rates +4pp and +12pp?
The +4 percentage points and +12 percentage points are illustrative offsets chosen to represent common real-world gaps. A borrower with a good but not excellent credit profile might receive a rate 3 to 5 percentage points above the representative. A borrower with a fair or poor profile might receive a rate 10 to 15 percentage points above. The +4pp and +12pp offsets sit in the middle of these ranges and produce representative illustrations of the cost gap.
The actual gap for any individual depends on the lender’s pricing model and the borrower’s specific profile. The “your rate” panel allows the user to enter the exact rate from an eligibility check, which replaces the illustrative offsets with a personalised figure. If the personal rate is available, it is always more accurate than the illustrative scenarios.
Is a lower representative APR always better?
For comparing the headline rate, yes: a lower representative APR means a cheaper product for the borrowers who receive it. But the representative APR does not tell you what rate you specifically will receive. A lender with a 5.9% representative APR that offers you 12% is more expensive than a lender with a 7.9% representative APR that offers you 8%. The personal rate, not the representative rate, determines the actual cost.
This is why comparing personal rates from eligibility checkers across multiple lenders is more useful than comparing representative APRs from adverts. The representative APR is useful for shortlisting (identifying lenders with broadly competitive pricing), but the personal rate from an eligibility check is the figure that determines the actual cost of borrowing.
Could the representative APR rules change?
The FCA published a consultation paper (CP26/15) in April 2026 inviting views on whether the representative APR framework should be updated. The consultation asks whether the 51% threshold should be changed (it was 66% before 2010, when the concept was called a “typical” APR), whether the word “representative” should be replaced, and whether total cost disclosures in pounds and pence should supplement or replace the APR in adverts. The consultation closed in June 2026 and the FCA expects to publish its outcome later in the year.
As of now, the current rules remain in effect. The representative APR is still defined by the Consumer Credit (Advertisements) Regulations 2010, and the 51% threshold still applies. If the rules change, this tool and the guidance on this page will be updated to reflect the new framework.
Squaring Up
The representative APR is the rate shown in every personal loan advert, and up to 49% of accepted applicants do not receive it. This tool shows what the gap costs: at the representative rate, at a near-prime rate, and at a higher rate, translated from percentage points into pounds of additional interest. For borrowers who have a personal rate from a soft-search eligibility check, the “your rate” panel shows exactly where they sit. The representative APR is useful for shortlisting lenders. The personal rate is the figure that matters for the actual borrowing decision.

What changed in this update
The calculator’s interest rate conversion was refined to use the effective annual rate method, which is the basis for how APR is legally defined in the UK. Illustrative figures in the article text were recalculated to match the updated tool output. The regulatory description was updated to reflect the precise wording of the Consumer Credit (Advertisements) Regulations 2010, and a new FAQ was added covering the FCA’s April 2026 consultation on potential changes to the representative APR framework.
The tool’s accessibility was improved with WCAG 2.1 AA-compliant colour contrast across all text elements, screen reader support (aria-valuetext for sliders, aria-live for dynamic results, explicit label associations), and non-colour tier indicators on the personal rate panel. The tool intro was updated to the site-wide standard styling.
This tool is for illustrative purposes only and does not constitute financial advice. The representative APR is a legal requirement under the Consumer Credit (Advertisements) Regulations 2010 and is described accurately. The near-prime and higher rate scenarios are illustrative composites and do not represent any specific lender’s pricing. The rate offered to any individual depends on their credit profile, income, existing commitments, and the lender’s own criteria. Missed repayments can affect your credit rating and may result in further action.
