Audi RS3 Finance Calculator: APRs, Pricing and Monthly Payments Explained
Financing an Audi RS3: The dealer's quote you've got might be impressive, or it might not be. There's only one way to know for sure.
Prefinance runs that check for you: we take the dealer's own finance example for the exact RS3 you're looking at and compare it against the best available rate from our panel of finance brokers for that type of vehicle. On average, that turns up savings of up to 30% against dealer finance — though that's an average across many deals, not a promise for yours, and some dealer RS3 finance is already competitively priced. Rates and calculations correct at time of posting but are subject to change.

Across Audi finance generally, Prefinance customers have seen an average APR of 8.81% through our panel, compared with a dealer average of 12.12%, working out to an average monthly saving of £59.26 and an average total saving of £2,738.09, based on 311 comparisons. Your actual saving will depend on your credit profile, the lender, and the specific deal in front of you.
What's the difference between PCP and HP on an RS3?
Both are hire purchase agreements in the legal sense — the car isn't yours until the final payment clears — but they split the cost differently. HP spreads the full price, minus your deposit, evenly across the term, so every payment builds toward ownership, which usually means a higher monthly figure than an equivalent PCP deal. PCP, which is what all four examples above use, defers a chunk of the price to a Guaranteed (Minimum) Future Value at the end, keeping the monthly payment down; you can then pay it to keep the car, hand it back, or roll it into your next one.
One assumption underpins the instant comparison: Prefinance assumes the new lender's GFV matches the dealer's own. If your matched broker structures it differently, your actual monthly payment could come out higher or lower than the illustrative figure.
How does Prefinance work out the saving?
You give us the vehicle by registration, by make and model, or by pasting in a link from a dealer site or a listings site like Autotrader, provided that page shows a finance example. We read the dealer's own quote and compare it against the best available rate from our broker panel for that type of vehicle. The comparison assumes you'd qualify for the panel's best rate, which depends on your credit profile, and that the dealer you're buying from is FCA authorised. Every comparison you run is saved, so you can come back and check previous ones too.
Representative APR means at least 51% of customers offered finance by that provider get that rate or better, a genuine benchmark, not a guarantee of your own rate.
What affects the rate you're offered?
Your credit score does most of the work, but deposit size, term length and the car's age move the number too, as the table above shows. A longer term usually lowers the monthly payment but adds to the total interest paid, worth weighing carefully on a car like the RS3, where depreciation and running costs are a bigger factor than on a family hatchback. And a factor most buyers never think about: dealers and brokers earn commission for arranging finance, which is a genuine reason two near-identical RS3s can be offered at different rates by different dealers; exposing that gap is a large part of what our comparison actually does.
On the maths: a flat rate of 5% on £35,000 over four years works out to roughly £1,750 a year in interest. As a rough rule of thumb, APR runs at close to double the flat rate, so a 5% flat rate typically shows up as something like a 9.8–9.9% APR.
What to check before you apply
Confirm the deposit and mileage in your comparison match the dealer's actual quote — the deposit is editable, but a mismatch elsewhere skews the result.
Ask what happens to your monthly payment if the matched lender's GFV differs from the dealer's — don't assume it'll match exactly.
Weigh term length carefully: a longer term lowers the monthly payment but adds to the total interest, as the 24-month and 60-month examples above show.
Read the broker's full representative example before signing anything — it carries the exact figures for your deal, not the illustrative ones above.
The only way to know whether the dealer's RS3 quote in front of you is already good is to run the comparison on your specific car and see what the panel delivers.
