BMW 1 Series Finance Calculator Explained
Financing a 1 Series? Before you sign the dealer's quote, compare it with Prefinance for potential savings.
Prefinance runs a comparison for you: we take the dealer's own finance example for the exact 1 Series you're looking at and set 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 1 Series finance is already competitively priced.

What's the difference between PCP and HP on a 1 Series?
Both are hire purchase agreements in the legal sense; the car isn't yours until the final payment is paid, but they split the cost differently. HP spreads the full price, minus your deposit, evenly across the term, so every payment builds toward ownership; that's exactly why the HP quote above on the 7,805-mile 1 Series comes out well above its own PCP quote on the identical car. PCP 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 either way: Prefinance assumes the new lender's GFV matches the dealer's own. If your matched broker structures it differently, your real monthly payment could come out higher or lower than the illustrative figure.
How does Prefinance work out the savings?
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 panel of brokers 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. How much you'd actually save depends on the specific car and your own circumstances. Dealers and brokers also earn commission for arranging finance, which is a real reason two near-identical 1 Series cars can be offered at different rates by different dealers; exposing that gap is a large part of what our comparison actually does.
What affects the rate you're offered?
Your credit score does most of the work, but deposit size, trim and term length all move the number too. As the table above shows, the two PCP/HP quotes on the identical 7,805-mile car are a clear illustration of how much the finance structure alone can shift the monthly figure. A longer term usually lowers the monthly payment but adds to the total interest paid, which is part of why the 60-month 128ti and M135i xDrive quotes above show comparatively modest monthly figures against their price.
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.
If comparing PCP against HP on the same car, look at both the monthly payment and whether you actually want to own the car outright at the end — the difference can be substantial, as the table above shows.
Looking at the 128ti or M135i xDrive? A longer term can flatter the monthly figure — check the total amount payable across the full agreement, not just the headline monthly number.
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.
Read the broker's full representative example before signing anything — it carries the exact figures for your deal, not the illustrative ones above.
None of this confirms upfront whether the dealer's 1 Series quote in front of you is already good... The only way to know for sure is to run the comparison on your specific car and see what the panel of brokers comes back with.
