Car Finance Refund Calculator 2026

Car Finance Refund Calculation

Understanding how much you could receive from a car finance refund claim can feel like tackling a complex maths problem. With the Financial Conduct Authority (FCA) currently reviewing historical car finance agreements, millions of people across the UK are wondering how they are affected by Discretionary Commission Arrangements (DCAs) and what their potential compensation might be.

This guide clarifies the FCA's approach to estimating potential compensation. You will discover the methodology behind calculating redress, including interest rate markups and the 8% compensatory statutory interest. By the end, you will have a clear understanding of the numbers involved and how our free tool simplifies your path to a claim.

Understanding Discretionary Commission Arrangement (DCA) Interest Markups

The heart of the car finance scandal lies in Discretionary Commission Arrangements (DCAs). These hidden financial structures allowed car dealers and brokers to inflate the interest rates on finance agreements, directly increasing the commission they earned.

What is a Discretionary Commission Arrangement (DCA)?

Before 28 January 2021, many car finance agreements included a DCA. This meant that the lender set a "benchmark" interest rate, but then allowed the dealer or broker selling the car to decide the final interest rate offered to you. The higher the interest rate they charged above the benchmark, the larger the commission payment they received from the lender.

The Conflict of Interest: This arrangement created a clear conflict of interest. Dealers and brokers had a direct financial incentive to offer you a higher interest rate, even if you qualified for a lower one. This meant you often paid more in interest than necessary, without ever knowing the true nature of the commission structure. The primary focus for the dealer shifted from securing the best deal for you to maximising their own profit.

When DCAs Were Banned: Recognising the widespread harm caused by this practice, the FCA banned DCAs on 28 January 2021. This measure prevented new agreements from exploiting this loophole, but the legacy of past agreements continues to impact millions.

How DCAs Led to Overpayments

DCAs operated in the shadows. Most consumers had no idea their interest rate included a hidden markup that benefited the dealer, not them. Your Annual Percentage Rate (APR) appeared as a single figure on your agreement, but underneath, a percentage of that rate was directly feeding a commission payment.

Inflated APR: The dealer's ability to adjust the APR meant that borrowers, often unaware they could have secured a lower rate, signed up for more expensive finance than they needed. This inflation of the APR directly translated into higher monthly payments and a greater overall cost of credit over the life of the agreement. Over months and years, these small increases accumulated into substantial overpayments.

Are You Eligible for a Claim?

Determining your eligibility forms the first step towards a potential refund. Not every car finance agreement qualifies, but millions do.

Agreements Covered: You could be eligible if you took out a Personal Contract Purchase (PCP) or Hire Purchase (HP) agreement with a motor finance provider between 6 April 2007 and 1 November 2024. The key factor involves an undisclosed DCA being in place on your agreement. The FCA's current review specifically targets these agreements.

Key Criteria for Eligibility:

• You entered into a PCP or HP agreement within the specified dates.
• The finance agreement included an undisclosed Discretionary Commission Arrangement (DCA).
• The agreement was with a regulated lender (which most mainstream providers are).
• You suffered financial detriment as a result (i.e., you paid more in interest).

Exclusions: Certain types of agreements fall outside the scope of this review. These commonly include:

• Finance agreements for leased cars (personal contract hire).
• Business finance agreements.
• Finance taken out directly with a manufacturer or dealer where no third party lender was involved.
• Agreements where the commission structure was fully transparent and non discretionary.

If you are unsure whether a DCA was part of your agreement, you can use our check if you had a DCA guide, or simply make a complaint; the lender will confirm the commission type.

The Official Compensation Formula: How the FCA Calculates Redress

The FCA initiated an industry wide review into historical car finance commission arrangements in January 2024. The goal revolves around ensuring consumers who were unfairly charged more due to DCAs receive appropriate redress.

FCA Redress Scheme Overview

An industry wide compensation scheme is now in motion, although the precise mechanics and exact payout dates remain subject to ongoing legal developments. The FCA's proactive intervention aims to avoid protracted individual court cases by establishing a standardised framework for compensation.

Expected Payouts: While specific figures depend on individual circumstances, initial estimates suggest average payouts could range from £700 to £830 per agreement. These figures reflect the estimated overpayments due to inflated interest rates and associated costs.

Current Status and Timelines: As of 17 August 2026, the FCA has paused the usual 8 week deadline for lenders to respond to complaints regarding DCAs. This pause allows the FCA to gather more information and resolve outstanding legal challenges. While the scheme aims for efficiency, delays are inevitable. Many anticipate that eligible consumers will start receiving payouts in late 2026 or 2027. You can stay informed about these developments by visiting our FCA car finance compensation scheme page.

Two Main Compensation Methods

The FCA has outlined two primary methods for calculating redress, designed to cover a range of scenarios. The specific method applied depends on the severity and nature of the DCA within your agreement.

Criteria: This approach usually applies if:

• An undisclosed DCA was in place.
• The commission paid to the dealer/broker was equal to or greater than 50% of the total cost of credit (the total interest and fees paid).
• AND the commission paid was equal to or greater than 22.5% of the original loan amount.

Calculation: If your case meets these stringent criteria, your compensation generally involves:

• The full amount of commission paid to the dealer or broker.
• Plus 8% simple compensatory interest on that commission amount, calculated from the date you took out the agreement until the date of your refund.

Compensation Formula: The redress amount calculated through this method equals the average of two components:

• Component A: Actual Commission Paid. This represents the exact amount the lender paid to the dealer or broker under the DCA.
• Component B: Estimated Loss based on APR Adjustment. This component calculates how much you overpaid due to the inflated APR. The FCA provides specific adjustments:

Plus: On top of the average of Component A and B, you will also receive 8% simple compensatory interest on this total redress amount, calculated from the agreement start date until the point of refund.

Expert Insight: The FCA's tiered APR adjustments reflect their analysis of average commission markups over different periods, recognising that market conditions and commission structures evolved, influencing the extent of consumer detriment.

Key Information You'll Need

To accurately estimate your potential refund, you will need to gather several key pieces of information from your original finance agreement:

• Amount financed (excluding deposit): The principal loan amount.
• Your actual Annual Percentage Rate (APR): This figure indicates the total cost of borrowing.
• Loan term (duration in years/months): How long your finance agreement lasted.
• Agreement start date: The date you entered into the finance agreement.
• Type of finance (PCP or HP): To confirm eligibility.

If you no longer possess your original agreement, contact your lender directly to request a copy. They are legally obliged to provide this information.

Step by Step Breakdown: Worked Example of Compensation Calculation

Let us walk through a realistic, simplified example using the Hybrid Approach, which will apply to most cases. This will demonstrate the maths involved, step by step.

Scenario

Mrs. Smith took out a Personal Contract Purchase (PCP) agreement for a car in May 2016.

• The amount financed (after her deposit) was £15,000.
• Her actual APR on the agreement stood at 9.9%.
• The loan term stretched over 48 months (4 years).
• Later, Mrs. Smith discovered a Discretionary Commission Arrangement was in place on her finance.

Step 1: Gather Agreement Details

To begin our calculation, we consolidate Mrs. Smith's finance agreement details:

• Amount Financed: £15,000
• Actual APR: 9.9%
• Loan Term: 48 months (4 years)
• Agreement Start Date: May 2016

Her agreement start date of May 2016 places her within the FCA's 17% APR adjustment bracket (agreements from 1 April 2014 to 1 November 2024).

Step 2: Calculate Total Interest Paid (Based on Actual APR)

Next, we determine the total interest Mrs. Smith paid over the life of her loan. For illustration, we will use an approximate total interest figure. Our car finance refund calculator automates this precise calculation, but for this example, we will assume a reasonable total.

• Example Calculation: A £15,000 loan at 9.9% APR over 4 years typically results in approximately £3,200 in total interest paid.

Step 3: Estimate a Fair APR (without DCA) and Corresponding Interest

Now we apply the FCA's methodology to estimate what a fair APR would have been without the DCA, and calculate the interest that would have been paid at this fair rate.

• Apply the FCA's APR adjustment: We take the actual APR and reduce it by the relevant FCA percentage.

• Example Calculation: A £15,000 loan at this adjusted 8.217% APR over 4 years would have resulted in approximately £2,650 in total interest paid.

Step 4: Calculate the Estimated Loss (Overpaid Interest due to DCA)

This step reveals the direct financial detriment Mrs. Smith likely suffered due to the inflated APR.

• Estimated Loss = Total Interest Paid (Actual APR) Total Interest Paid (Fair APR)
• Example Calculation: £3,200 (actual interest) £2,650 (fair interest) = £550.

* This £550 represents Component B of the Hybrid Approach.

Step 5: Determine the Commission Paid to the Dealer

The actual commission paid to the dealer forms Component A of the Hybrid Approach. This information is held by the lender and will be confirmed upon complaint. For the purpose of this example, we will assume a plausible figure for the commission.

• Assumed Commission: Let us assume the lender confirmed a commission payment of £400 to the dealer.

Step 6: Apply the Hybrid Formula (Average of Commission and Estimated Loss)

With both components identified, we now apply the Hybrid Formula to determine the initial redress amount.

• Average Redress = (Estimated Loss + Assumed Commission) / 2
• Example Calculation: (£550 (Estimated Loss) + £400 (Assumed Commission)) / 2 = £950 / 2 = £475.

* This £475 represents the core redress amount before compensatory interest.

Step 7: Add Compensatory Interest

The FCA's scheme also includes compensatory interest to account for the time you have been without your money. For these claims, the standard 8% simple compensatory interest will be applied from the date of the loss (agreement start date) until the refund is paid.

• Time Period for Interest: Mrs. Smith's agreement started in May 2016. As of 17 August 2026, this spans approximately 10 years and 3 months. For simplicity in this example, we will use 10 years.
• Interest Calculation: Compensatory Interest = Redress Amount Annual Interest Rate Number of Years
• Example Calculation: £475 0.08 10 years = £380.
• Total Estimated Payout = Initial Redress + Compensatory Interest
• Total Estimated Payout = £475 + £380 = £855.

Based on this worked example, Mrs. Smith could expect an estimated payout of £855.
